Warren Edward Buffett was born on August 30, 1930, to his mother Leila and father Howard, a stockbroker-turned-Congressman. The second oldest, he had two sisters and displayed an amazing aptitude for both money and business at a very early age. Acquaintances recount his uncanny ability to calculate columns of numbers off the top of his head
While other children his age were playing hopscotch and jacks, Warren was making money. At only six years old, Buffett purchased six-packs of Coca-Cola from his grandfather’s grocery store for 25 cents and resold each of the bottles for a nickel, pocketing a 5-cent profit. Five years later, Buffett took his first step into the world of high finance.
Find your passion
At eleven years old, he purchased three shares of Cities Service Preference at $38 per share for both himself and his older sister Doris. Shortly after buying the stock, it fell to just over $27 per share. A frightened but resilient Warren held his shares until they rebounded to $40. He promptly sold them—a mistake he would soon come to regret. Cities Service shot up to $200.1 The experience taught him one of the basic lessons of investing: Patience is a virtue.

Banking in India in the mdern sense originated in the last decades of the 18th century . The first banks were Bank of Hindustan (1770-1829) and the General Bank of India established 1786. The largest bank and the oldest still in existence, is tge State bank of India, which originated in the Bank of Calcutta in June 1806 , which almost immediately became the bank of Bengal. This was one of the three presidency banks , the other two being The Bank of Bombay and The bank of Madras , all three of which were established under charters from the British East India Company. The three banks merged in 1921 to form the Imperial Bank of India , which , upon India’s independence became the State Bank of India in 1955. For many years the presidency banks acted as quasi-central banks , as did their successors until the reserve Bank of India was established in 1935 .
Reserve bank of India (RBI)
The Reserve Bank of India is India’s central banking institution, which controls the monetary policy of the Indian rupee. It commenced its operations on 1 April 1935 during the British Rule in accordance with the provisions of the Reserve Bank of India Act,1934 and in 1949 it was nationalized.The central office of the Reserve Bank was initially established in Calcutta but was permanently moved to Mumbai in 1937. The central office is where the Governor sits and where policies are formulated. Sir CD Deshmukh is the first Governor of RBI. The RBI has four zonal offices at Chennai, Delhi, Kolkata, Mumbai and 20 regional offices mostly located in the state capitals and 11 sub-offices. Reserve Bank of India Act,1934 is the legislative act under which the Reserve Bank of India was formed. This act along with the Comapnies Act, which was amended in 1936, were meant to provide a framework for the supervision of banking firms in india.
Scheduled and non-scheduled banks
Scheduled banks in India refer to those banks which have been included in the second schedule of Reserve Bank of India Act, 1934. Banks not under this schedule are called non-scheduled banks. In other words, Banks with a reserve capital of less than 5 lakh rupees qualify as non-scheduled banks. Unlike scheduled Banks , they are not entitled to borrow from the RBI for normal banking purposes, except, in emergency or ‘abnormal circumstances’. Coastal local Area Bank Ltd. (Vijayawasa,AP), Capital Local Area Bank Ltd. (Phagwara, Punjab), Krishna Bhima Samrudhi Local Area Bank Ltd. (Mehbubnagar, Telangana), Subhadra Local Area Bank Ltd. (Kolhapur, Maharashtra) are the only non-scheduled banks in India.
Scheduled banks are further internally classified into commercial banks and cooperative banks.
Public Sector Banks
Public sector banks (PSBs) are banks where a majority state (ie., more than 50%) is held by a government . The shares of these banks are listed on stock exchange. There are a total of 21 PSBs in India and State Bank of India group.
In 1969, the Indira-Gandhi headed government nationalised 14 major commercial banks ( Allahabad Bank , Bank of Baroda , Bank of India , Bank of Maharashtra , Canara Bank , Central Bank of India , Dena Bank , Indian Bank , Indian Overseas Bank , Punjab and Sindh Bank , Punjab National Bank, Sindicate Bank , UCO Bank , United Bank of India)
In 1980 , a further 6 banks were nationalised (Andhra Bank , Cooperation Bank , New Bank of India , Oriental Bank of Commerce, Punjab and Sindh Bank , Vijay Bank )
IDBI Bank is an Indian government-owned financial service company, formarly known as industrial Development Bank of India , headquartered in Mumbai , India .It was established in 1964 and nationalised in year 2005 .
Private Sector Banks
The ‘Private- Sector’ banks are baks where greater parts of share or equity are not held by the government but by private shareholders . There are many Indian and Foreign Banks in India . HDFC Bank , ICICI Bank , Axis Bank , Kotak Mahindra Bank , Yes Bank , IDFC Bank , RBL Bank , Federal Bank , City Union Bank are the major private banks in India.
Regional Rural Banks
Regional Rural Banks were formed on October 2,1975 upon the recommendations of M. Narsimham working group during the tenure of Indira Gandhi’s government. The object behind the formation of RRBs was to serve large unserve population of rural areas and promoting financial inclusions . They have been created with a view to serve primarily the rural areas of India with basic banking and financial services. However, RRBs may have branches set up for urban operations and their area of operation may include urban areas too.
CooperativeBanks
The cooperative banks are furtger classified into:
State cooperative banks: These are small financial institutions which are governed by regulations like Banking Regulations Act , 1949 and Banking Laws Cooperative Socities Act ,1965 . At present there are about 33 state cooperative banks of which 19 are scheduled.
Urban/ Central cooperative banks: The term urban cooperative banks (UCB) refers to primary cooperative banks located in urban and semi-urban areas . These banks till 1996 , were allowed to lend money only for non-agricultural purposes. This distinction does not hold today . They essentially lent to small borrowers abd business . There are about 2,104 UCBs of which 56 were scheduled Banks. About 79 percent of these are located in 5states- Andhra Pradesh, Gujarat, Karnataka, Maharashtra and Tamil Nadu .
Primary credit Socities: Primary Credit Societies or primary agricultural credit society (PACs) is a basic unit and smallest cooperative credit institutions in India. It works on the grassroot level (Gram panchayat and village level ) . It virtually function like banks , but whose net worth is less than Rs. 1 lakh; who are not members of the payment system and to whom deposit insurance is not extended .
With the rise in the online world of work, digital marketing is emerging as a crucial field of marketing. In 2019, digital marketing surpassed traditional marketing for the first time. This is due to the fact that, consumers are increasingly getting involved with the online channels. Due to the pandemic, nearly all utilities and services are shifting towards the online mode. In such scenario, digital marketing is increasingly getting popular and necessary to sustain businesses. Digital marketing refers to the marketing that is done using internet or online based technologies like laptops, mobiles, or other digital devices. It is basically advertisements done through digital platforms such as search engines, websites, social media, email, and mobile apps. By implementing an a sound digital marketing strategy, marketers can collect valuable insights into target audience behaviours while opening the door to new methods of customer engagement. Additionally, companies can expect to see an increase in profits. Digital marketing revolves around 5Ds: digital devices, digital platforms, digital media, digital data, and digital technology. The first of the 5Ds mainly focuses on digital devices such as smartphones, tablets, desktop computers, TVs, and gaming devices. It mainly deals with the target audience’s interaction and engagement on websites and mobile applications. Digital platforms like Facebook, Twitter, LinkedIn, YouTube, Instagram etc. Are the preferred platforms to capture the attention of target audience. Digital media revolves around paid, owned, and earned communications channels utilized to build engagement with the target market through several ways such as advertising e-mails, messaging, search engines, and social networks. Digital data refers audience profiles and engagement patterns with businesses. Digital technology on the other hand focuses on building interactive experiences across a wide range of platforms, from your websites and mobile apps. To gain an upper hand in the sphere of digital marketing, it is important to understand and creatively utilize the 5Ds for the benefit of the company or business. There are many platforms that assist in digital marketing. Social media is a great way to promote products or resources organically to brand followers, and engage with consumers. A vast majority of individuals have more than single social media accounts. Platforms like Facebook, Instagram etc. Are very popular and helpful in reaching out to a large audience. Social media platforms allow marketers to reach their prospects in a variety of ways. Marketing teams can use these channels to distribute paid ads and sponsored content. Each platform is different so one can choose accordingly but most have capabilities that allow marketing teams to place ads based on location, job title, interests, age, etc. E mail marketing is also very useful. It allows organizations to stay connected with prospects and customers, sending them customized newsletters or offers based on past shopping history or brand engagements. Even consumers agree that email plays a role in their purchase decisions. Furthermore, transactional emails are more likely to be opened by subscribers. Digital marketing platforms span several functions in one solution – allowing marketing teams to get a more integrated / holistic view of their campaigns.
Asymmetric information, also known as “information failure,” occurs when one party to an economic transaction possesses greater material knowledge than the other party. This typically manifests when the seller of a good possesses greater knowledge than the buyer; however, the reverse dynamic is also possible. Almost all economic transactions involve information asymmetries. Asymmetric information can also be viewed as the specialization and division of knowledge, as applied to any economic trade. Asymmetric information examples are everywhere. In the financial world, consider a situation where a lending firms enters into an agreement with a borrower. The lender establishes the terms and agreements that the borrower must stipulate to, and, usually, background checks are done.
Moral hazard is a situation in which one party gets involved in a risky event knowing that it is protected against the risk and the other party will incur the cost. It arises when both the parties have incomplete information about each other.
In a financial market, there is a risk that the borrower might engage in activities that are undesirable from the lender’s point of view because they make him less likely to pay back a loan. It occurs when the borrower knows that someone else will pay for the mistake he makes. This in turn gives him the incentive to act in a riskier way. This economic concept is known as moral hazard.
Adverse Selection describes a situation in which one party in a deal has more accurate and different information than the other party. The party with less information is at a disadvantage to the party with more information. This asymmetry causes a lack of efficiency in the price and the number of goods and services provided. Most information in a market economy is transferred through prices, which means that adverse selection tends to result from ineffective price signals.

MEPAP(MULTIPURPOSE ELECTRICITY PRODUCER INTEGRATED WITH AIR PURIFIER)
WHAT MADE ME TO DO THIS PROJECT
I was from a lower middle class family. We suffered many months without electricity and our area is prone to traffic so our area is filled with smoke and dust. Many were suffering from several respiratory disorders due to this dust and smoke. These made me to think of inventing a low cost electricity generator
The growing demand for electrical energy and increasing air pollution around the globe is the main factor that driven my research.
More than 80 percent of our energy today comes from burning fossil fuels, which is both harmful to our environment and unsustainable as well. My invention will help to solve the energy crisis by improving the efficiency of electromagnetic energy-harvesting systems, vibration energy-harvesting systems , wind energy-harvesting systems, thermal energy harvesting system and air cleanser all in a single project.
Due to increase in the carbon dioxide level and other harmful gases specially which are contributing in increase in pollution and global warming, our automobile industries are one of the easy and clear target therefore many researches has been undertaken in this field . Globally, it is estimated that about 1/3 of the total energy is utilized while remaining is rejected as waste heat. The maximum efficiency of an engine is around 25% which means that 75 % of the energy left is wasted in the form of heat from parasitic losses and friction which causes 30% waste in the engine coolant and 40% in the form of gases in exhaust.
The given figure shows the energy distribution in an Internal Combustion Engine.
MEPAP’S AIR PURIFIER
FEATURES AND WORKING
MEPAP AIR CLEANSER IS AN AIR PURIFIER WHICH PURIFIES AIR FROM THE SOURCE (VEHICLES AND FACTORIES EXHAUST) WHERE IT IS PRODUCED.
IT IS MADE TO REDUCE THE AIR POLLUTION
The compact purifier is an apt solution for the increasing pollution. The Active Oxidization Cell with its self-cleaning abilities keeps the purification process on, while the 360º air flow guards us from harmful impurities by distributing healthy air.
Active shield
The purification process eliminates sub-micron respirable particles and infection carrying microbes in the air.
Active Carbon Filter
The most advanced technology filters out bad odor, toxic gases and other harmful gases including VOCs (Volatile Organic Compounds) from the air you breathe in. The carbon filters have excellent absorbent qualities to soothe respiratory discomforts by eliminating irritants in the air.
ICC (Improved Catalytic Converter): Catalytic converters, having expensive metals namely platinum-palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases. As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide are changed to carbon dioxide and nitrogen gas, respectively. To overcome from cost and reducing the rare metal usage the project made the drive to develop an alternate source of oxidation catalyst for oxidation reaction and thus reduces the NOx and HC emissions. The substrate selected in this project is wash coat technology employed by using the silicon dioxide and alumina with silica. The catalytic converter is constructed with inner/outer shell construction supported with cones and flanges. The initial emission readings are conducted in the experimental engine. This catalytic converter reduces the harmful pollutant more efficiently and at a lower cost than the conventional catalytic converter.
Honeycomb Active Carbon Filter
The carbon filters have excellent absorbent qualities to eliminate repulsive smell, toxic gases and other odor, leaving behind fresh and pure air to breathe.
HEPA (High Efficiency Particulate Air Filter) Type Filter
The HEPA type filter removes airborne pollutants and eliminates ultra-fine particles like bacteria, pollen, and mould, which cannot be done by other air purifiers.
Anion Generator
The technology ensures that the air you breathe has no positive ions, leaving you rest assured of living in a no impurities zone. Negative ions produced by purifier bind themselves with airborne pollutants and removes them from the air thereby creating a fresh and cleaner environment
Air pollution sensors
Air pollution sensors are devices that detect and monitor the presence of air pollution in the surrounding area. They can be used for both indoor and outdoor environments. These sensors can be built at home, or bought from certain manufactures. Although there are various types of air pollution sensors, and some are specialized in certain aspects, the majority focuses on five components: ozone, particulate matter, carbonmonoxide, sulfur dioxide, and nitrous oxide.
FUTURE PLAN FOR AIR PURIFIER PART
Carbon Separator and Collector: Carbon dioxide is considered a major reason for global warming. The element jeopardizes people’s health, threatens national security, and endangers basic human needs. Yet, it also holds great promise as a fuel of the future.
The carbon dioxide splitter, which consists of copper and tin.
The splitter has an atomic layer of tin in order to trap the energy that would be lost if copper is utilized as an electrode. It also has a thin membrane between the cathode and anode to improve the reaction.
The splitter can open windows to solving the problem of storing energy from renewable sources by turning it straight into liquid fuel.
The process of splitting is efficient and carbon-neutral. It is already a well-known method of producing fuel without increasing the level of carbon dioxide in the atmosphere. CO2 is split into oxygen and carbon monoxide.
Carbon monoxide can be incorporated with hydrogen to create synthetic carbon-based fuel. CO2 is taken out of the atmosphere without being put back in, which produces clean fuel.
MEPAP ELECTRICITY GENERATOR GENERATES ELECTRICITY WITH THE HELP OF VIBRATRION(Piezoelectric Materials) AND ELECTROMAGNETIC RADIATION(with the help of MetaMaterials) ELECTROMAGNETIC induction [inductive coupling(power density is proportional to d, q, 1/d^3)] and wind energy( from purifier where mini turbine is connected with dynamo) AND ALSO THERMOELECTRIC ENERGY (power density=25µW/cm^2).
ELECTRICITY from VIBRATRION
MEPAP ELECTRICITY GENERATOR could produce enough electricity from random, ambient vibrations to power a wristwatch, pacemaker, wireless sensor , phones etc..,
MEP are highly efficient at providing renewable electrical power from arbitrary, non-periodic vibrations. This type of vibration is a byproduct of traffic driving on bridges, machinery operating in factories and humans moving their limbs.
In two of the sub generators present in PFIG (Parametric Frequency Increased Generators), the energy conversion is performed through electromagnetic induction, in which a coil is subjected to a varying magnetic field. This is a process similar to how large-scale generators in big power plants operate. It also uses piezoelectric material, which is a type of material that produces charge when it is stressed. This version has applications in infrastructure health monitoring. The generators could one day power bridge sensors that would warn inspectors of cracks or corrosion before human eyes could discern problems.
Power Density= 4 µW/cm^2
MECHANISM AND APPLICATIONS:
It contains a resonator which is used to amplify the vibration source, and a transducer device which changes the energy from the vibrations into electrical energy. The transducer consists of a magnet and coil of a piezoelectric crystal.
A number of crystals can emit an electric current when compressed or they can change shape when an electric charge is employed. This piezoelectric effect is used in ultrasound and sonar devices, as well as energy harvesting.
Piezoelectric generators utilize thin casings or beams made of piezoelectric crystals as a transducer mechanism. When a crystal is placed under strain by the kinetic energy of the vibration, a small quantity of current is produced because of the piezoelectric effect. These mechanisms are generally straightforward with few moving parts, and they have a very long service life, making them the most prevalent technique of harvesting the energy from vibrations. It is fabricated by MEMS process.
This device uses a freely rotating, unconventional brass rotor with an implanted magnet, and multiple PZT beams with a magnet on each beam.
As the magnet on the rotor draws near one of the beams, the magnets repel each other and deflects the beam, pulling the beam in a process that is described as frequency up-conversion. The gradual rate of a rotating wrist is changed into a higher frequency oscillation. This device is more efficient than a standard electromagnetic harvester, as such as those used in self-powered watches.
Another application, which is in the early stages of development, desires to use the vibrations generated during aircraft flight to power the electronics on the plane that currently depend on on batteries. Such a system would produce a reliable energy source, and reduce maintenance, since batteries would not need to be replaced and piezoelectric systems have a long service life. This system uses a resonator, which permits the airflow to produce a high amplitude steady tone. This is the same principle that is used in many wind instruments by converting the airflow furnished by the musician into a loud steady tone. This tone is used as the vibration that is transformed from kinetic to electric energy by the piezoelectric generator
ELECTRICITY from ELECTROMAGNETIC RADIATION:
Electromagnetic energy harvesting based on the “full absorption concept.” This involves the use of metamaterials that can be tailored to produce media that neither reflects nor transmits any power—enabling full absorption of incident waves at a specific range of frequencies and polarizations since the inception of collecting and harvesting electromagnetic energy, classical dipole patch antennas have been used. “Now, my technology introduces ‘metasurfaces’ that are much better energy collectors than classical antennas. microstrip patch antennas areused because of their low profile, light weight, and planar structure for RF harvesting.
Metasurfaces are formed by etching the surface of a material with an elegant pattern of periodic shapes. The particular dimensions of these patterns and their proximity to each other can be tuned to provide “near-unity” energy absorption. This energy is then channeled to a load through a conducting path that connects the metasurface to a Electromagnetic energy collector.
We can also channel the absorbed energy into a load, rather than having the energy dissipate in the material as was done in previous works. Other key applications include “wireless power transfer—directly adaptable to power remote devices such as RFID devices and tags or even remote devices in general.
The technology can also be extended to the infrared and visible spectra
Power Density= 25µW/cm^2.
ELECTRICITY from ELECTROMAGNETIC RADIATION(RF):
Wi-Fi signals are made of radio waves. Receiving antennas can wirelessly harvest electromagnetic radiation in the Wi-Fi (2.4 GHz and 5.9 GHz), global satellite positioning (1.58 GHz and 1.22 GHz), the cellular communications fourth-generation (4G) (1.7 GHz and 1.9 GHz), and Bluetooth (2.4 GHz) bands and convert the energy from these electromagnetic waves to alternating current (AC). The AC electricity is then sent to the rectifier, which converts it to direct current (DC) electricity.
Using a rectifier made from a molybdenum disulfide (MoS2) layer that is only 3 atoms thick. At this thickness, the MoS2 behaves differently than the bulk material — the atoms rearrange themselves when exposed to certain chemicals. This means the material can behave like a switch, changing from a semiconductor to metallic structure. The MoS2 creates what’s called a Schottky diode, a junction of semiconductor and metal. The diode described in their paper can convert signals at higher frequencies because the structure reduces the extra energy stored by certain materials used in electronics, known as parasitic capacitance. The researchers’ design reduces parasitic capacitance by an order of magnitude compared to current flexible rectifiers, meaning they can capture the previously elusive high-frequency Wi-Fi band radio waves.
ENERGY FROM TERAHERTZ(will implement in future.):
Terahertz waves are electromagnetic radiation with a frequency somewhere between microwaves and infrared light. Also known as “T-rays,” they are produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.
Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. However, to date there has been no practical way to capture and convert them into any usable form.
MEPAP device would be able to convert terahertz waves into a direct current in future, a form of electricity that powers many household electronics.
This design (referred from MIT ) takes advantage of the quantum mechanical, or atomic behavior of the carbon material graphene. They found that by combining graphene with another material, in this case, boron nitride, the electrons in graphene should skew their motion toward a common direction. Any incoming terahertz waves should “shuttle” graphene’s electrons, like so many tiny air traffic controllers, to flow through the material in a single direction, as a direct current.
Rectifiers, devices that are designed to convert electromagnetic waves from their oscillating (alternating) current to direct current.
Most rectifiers are designed to convert low-frequency waves such as radio waves, using an electrical circuit with diodes to generate an electric field that can steer radio waves through the device as a DC current.
Solar Energy:
Photovoltaic (PV) solar panels use the sun’s power to create a flow of electricity. This is the most widely adopted method of harvesting solar energy today. These panels, which range in size from a few square centimeters to a few square meters, are constructed from many PV cells arranged in an intricate matrix. Intuitively, the larger the surface area available for sunlight to penetrate the PV cells, the more solar energy that gets harvested.
Each PV solar cell is generally made up of a compound semiconductor wafer structure, which can either be a monocrystalline or polycrystalline structure. The structure’s two thin semiconductor wafers, one P-type and one N-type, are each grown separately. The two wafers are placed on top of each other, and the natural reaction that occurs between the two semiconductor types creates a depletion zone that reaches an equilibrium point, without generating any electricity. Due to the PV cell, when light photons pass through and connect with the semiconductor wafers, their interaction releases enough energy to create an equilibrium disruption in the depletion region. That action subsequently creates a brief flow of electricity. However, because of the constant presence of light, this interaction occurs continuously and can produce massive amounts of electrical energy.
The power produced by a single photon interaction replicates across the entire surface of the PV cell. It’s compounded into a whole panel of solar cells. This minor interaction in the depletion zone can be repeated and multiplied, resulting in a significant amount of electricity. PV solar arrays, however, produce DC power. To be integrated with modern power transmission technology, such as the outlets in your home, this DC energy must be converted to AC power using an inverter. There are a variety of proprietary iterations of this fundamental technology that seek to optimize the efficiency of each PV cell on a molecular level, the assembly of the panel, and the panel’s ability to be integrated into a larger solar array.
Thin-film solar cell, type of device that is designed to convert light energy into electrical energy (through the photovoltaic effect) and is composed of micron-thick photon-absorbing material layers deposited over a flexible substrate.
Cadmium telluride thin-films have a peak recorded efficiency of more than 22.1 percent (the percentage of photons hitting the surface of the cell that are transformed into an electric current). By 2014 cadmium telluride thin-film technologies had the smallest carbon footprint and quickest payback time of any thin-film solar cell technology on the market. This is the reason why I used Cadmium telluride thin-film in MEPAP.
Power Density= 1000µW/cm^2
Energy Harvesting from a Vehicle’s Exhaust System Using Thermoelectric Generator Module(TEG):
The efficiency in an internal combustion engine ranges from 25% to 35%. About 50% – 85% of the overall energy loss in a combustion engine is heat, which is either cooled away by the vehicle’s radiator or blown out with the exhaust gases. The other losses take place in bearings and gear boxes. This energy is never put into use again and therefore is called “waste heat”. Even if a small fraction of the waste heat could be turned into useful energy again, it would be a step to the right direction of improving fuel economy.
TEG in MEPAP is a solid stated device which works on the principle of ‘Seebeck effect’.
They are found in solar energy systems like solar panels, solar hot water system, biomass power applications, energy power plants and solar pond systems .Installing a TEG with MEPAP is easy and very beneficial as it has some advantages like small in size, it has no vibrations, makes less or no noise while operating, it generally requires less or no maintenance. And major advantage is that it is using free thermal energy and converting into useful electrical energy. A thermoelectric module consists of many thermo elements connected in electrical channel in series to increase the operating voltage and to increase the thermal conductivity they are connected in parallel. According to a research the conversion of this waste heat into electricity results to an increase of fuel efficiency about 20% . A TEG in MEPAP works on the principle of a Seebeck effect. Two metallic strips, made of different metals and joined at the ends to form a loop. If the junctions are kept at different temperatures then there is an electric current in the loop and the emf developed is called the SEEBECK emf or thermo emf and the current can be used to power a load.
The TEG in MEPAP structure is sandwiched with the thermoelectric material which is then sandwiched by the heat exchanger plates at their ends respectively. The two heat exchangers remains at different temperatures, one at high temperature and the other at lower temperature and called the hot side and cold side. A thermally insulated layer is present between metal heat exchanger and material of a TEG in MEPAP. The p type and n type materials are connected by the metal electrically. A TEG in MEPAP consists of a two sides, one is cold and other is hot side. The hotter side derives the electrons in n type leg towards the cold side which pass through the metallic connection and then passes into the p type leg, hence develops current. Larger the temperature difference between cold side and hot side, larger value of emf will produce.
TEG Power Generation Calculation:
The equation involved in calculation of the performance of a TEG
Z = α2/ kR
Z is a figure of merit of thermoelectric material, R is the electric resistivity
k is a thermal conductivity and
α is a Seebeck coefficient which is
α = ∆V / ∆T,
THERMOELECTRIC METALS:
Thermoelectric materials are used in automobiles, power plants, space satellite, etc. Thermoelectric materials can be characterized according to the structure and composition. They can be classified as – chalcogenide, clathrates, skutterudites, half-heusler, oxides and silicides. The most common thermoelectric materials are the alloys of chalcogenide. The calcogenide materials are popular for their use with (Bi2Te3) and (PbTe).Thermoelectric materials made with Bi2Te3, Se and Sb for temperature use are economical. PbTe has better thermo electric properties at temperature range 500-600 ⁰C and has been used by NASA as a radioactive thermo electric generator (RTG’s) . The stability of a TE material is very important as it should not oxidize within the operating temperature when exposed in air .But nowadays; automobile industries are focusing on bismuth telluride for constructing a TEG.
High charge mobility and small band gaps are the properties of two heavy elements Bi and Te and Bulk alloys of PbTe have a zT value of 0.7 at 467 ⁰C. When SrTe and PbTe are doped with Na, zT value was 2.2 at 642 ⁰C .Skutterudites (MX3) have a lower thermal conductivity due to its complex crystal structure has large voids. CoSb3 based skutterudites are versatile in accepting various actinides, lanthanides, alkalis and alkaline earth metals to be used in void filling and thermal conductivity of skutterudites lowers as the size decreases .Compounds of half heuslers are intermetallic compounds which are thermally stable, having high thermal conductivity and corresponding seebeck coefficient. The lattice thermal conductivity of these compounds reduces having nano structures due to phonon scattering. SiGe alloys are used for high temperature applications because of having very low degradation up to 1000 ⁰C. When compared to their bulk alloys, nanostructured SiGe alloys have higher zT value. Bulk Si0.8 Ge0.2 has zT value of 1 and 0.6 for n type and p type respectively. There is an improvement in zT value when nanocomposite thermoelectric materials are used.

FIG. 2 is a section view taken along line A—A of FIG. 1.
BRIEF DESCRIPTION OF DRAWINGS:
Hereinafter, a preferred embodiment of a combination air purifier and wind generator according to the present invention will be described in detail with reference to the accompanying drawings.
FIGS. 1 and 2 are sectional views of a combination air purifier and magnet-type wind generator according to the present invention. Reference numeral 1 designates a box-type housing, 2 designates a wind-receiving unit, 3 designates an air purifier, and 10 designates an electric generator.
Each of the electric generators 10 is a conventional model for converting mechanical energy into electrical energy. A shaft of the electric generator 10 is coupled with a gear 11.
The electric generator 10 is installed within the box-type housing 1 made of steel frame and plate, or the like. The gear 11 of the electric generator 10 is engaged with and rotated together with a gear 12 coupled with a lower end of a central shaft 13 which penetrates through the center of a top surface of the box-type housing 1 and is positioned in the box-type housing 1. Thus, the gear 11 connected to components for generating electricity, such as a coil and a magnet that are not shown in the figures, within the electric generator 10 converts the mechanical energy into the electrical energy.
The wind-receiving unit 2 installed on the central shaft 13 includes three wind-resistant bodies: a governor 7 fixed to an upper end of the central shaft 13, a spherical blower 6 disposed below the governor, and planar magnetic rotary plates 5 disposed below the blower 6 for receiving both artificial and natural winds.
The governor 7 fixed to the upper end of the central shaft 13 is a horizontal centrifugal rotary body and includes a plurality of cylinders 73 of which one ends are fixed to the central shaft 13, a plurality of wind cups 72 of which one ends are slidably installed within the respective cylinders 73, and springs 75 connected with the inner ends of the wind cups 72 and inner walls 74 of the cylinders 73 for elastically supporting them.
The blower 6 installed in the middle of the central shaft 13 takes the shape of a sphere defined by a plurality of grouped winglets and can obtain a rotational force even with gentle winds generated in all directions. Further, since the blower 6 is disposed in the middle of the central shaft, it can serve to provide a starting force to the central shaft 13 upon existence of the gentle wind while keeping the balance of the central shaft 13, thereby preventing the central shaft 13 from stopping.
Each of the planar magnetic rotary plates 5 installed at a lower portion of the central shaft 13 is made in the form of a rectangular bucket as shown in FIG. 2. Upper magnets 4′ are attached to the bottoms of the respective magnetic rotary plates. Repulsive forces are produced between the upper magnets 4′ and lower permanent magnets 4 (20,000 gauss or higher) that have the same polarity as the upper magnets and are attached to the top of the box-type housing 1, and thus, a levitation phenomenon occurs therebetween. Accordingly, weights of all the components installed on the central shaft 13 become zero, so that the magnetic rotary plates can be easily rotated even with the gentle wind by means of a rotational action resulting from the repulsive forces between the magnets having the same polarity. Consequently, the rotational ability of the magnetic rotary plates can be improved even under any windy conditions. Particularly, the magnetic rotary plates are constructed to be forcibly rotated with the artificial wind discharged from a blower 36 of the air purifier 3 to be described later, even in the gentle natural wind or windless state.
Moreover, as shown in FIG. 2, the wind cups 72 of the governor 7 and the magnetic rotary plates 5 are staggered so that the wind sequentially and consecutively encounters the wind cups 72 and the magnetic rotary plates 5. Thus, a continuous rotational force is transmitted to the central shaft 13.
The air purifier 3 is fixedly installed on a side of the top of the box-type housing 1 and is Y-shaped by including two air inlets 31, 31′ and one air outlet 32. One of the air inlets 31 is horizontally in line with the air outlet 32 while the other air inlet 31′ is formed to incline upward, so that a wind can be generated due to a change in ambient airflow resulting from drawn air streams and a discharged air stream. Further, a copper net 33, a silver net 34 and a hard charcoal/zeolite net 35 for purifying the polluted air are disposed to be spaced apart from one another at predetermined intervals within the air purifier so that the polluted air is caused to pass through them and to be purified. The blower 36 is interposed between the silver net 34 and the hard charcoal/zeolite net 35 so that the air is forced to be drawn and discharged. Mosquito nets 37, 37′ can be installed at the air inlets 31, 31′ to prevent insects from entering the air purifier.
Reference numeral 8, which has not yet been explained, designates a bearing for ensuring smooth rotation of the central shaft 13.
Next, the operation of the combination air purifier and wind generator according to the present invention will be described.
When the box-type housing 1 of the combination air purifier and wind generator is installed at a desired location such as the interior of a room or a roadside, a no-load state suitable for rotation of the central shaft 13 is achieved by means of the repulsive forces between the upper magnets 4′ in the magnetic rotary plates 5 and the lower magnets 4 attached to the box-type housing 1. Thus, even though a very gentle wind encounters the blower 6, the wind cups 72 of the governor 7 and the magnet rotary plates 5, the central shaft 13 immediately begins to be rotated and is further accelerated by the action of the repulsive forces between the lower and upper magnets 4, 4′. Accordingly, the desired electricity can be easily obtained through the electric generators 10.
In order to reduce loads and cause the rotational speed of the central shaft 13 to reach a normal rotational speed in a short time upon initial rotation of the central shaft 13, the wind cups 72 of the governor 7 are maintained in a state where they are pulled toward the central shaft 13 by the springs 75. The wind cups 72 are kept in the initial starting state without any change in their state so as to facilitate the rotation of the central shaft 13 until rated electricity is provided through normal electricity generation.
The initial rotation of the central shaft is facilitated even with the gentle wind by means of the repulsive forces between the lower and upper magnets 4, 4′, the inward positioned state of the wind cups 72, and the spherical blower 6. Further, the magnetic repulsive forces and the inward positioned state of the wind cups 72 continuously assist the central shaft 13, which has begun to be rotated, to cause its rotation speed to reach the rotational speed at which the desired rated electricity can be generated.
Meanwhile, if the intensity of the wind is increased in a state where the rotational speed of each electric generator 10 reaches a normal rotational speed, the rotational speed of the central shaft 13 is also increased and thus the electric generator may be burdened with an overload.
In order to protect the electric generator 10 against the overload, if the central shaft 13 is rotated with a rotational force larger than a predetermined rotational force, the wind cups 72 of the governor 7 are urged outward from the center of the central shaft 13 by centrifugal forces to reduce its rotational force. On the contrary, if the rotational force of the central shaft 13 begins to be reduced, the wind cups 72 are pulled toward the central shaft by means of the restoring forces of the springs 75 so as to reduce the centrifugal forces. Therefore, it is possible to always maintain the normal rotational speed of the central shaft 13.
Meanwhile, in the very gentle natural wind state or the windless state, the blower 36 of the air purifier 3 is operated using either electric power, which has been generated by the electric generators 10 and then stored, or separate electric power. With the operation of the blower 36, the ambient polluted air is caused to be introduced into the air inlets 31, 31′. This causes a change in airflow thereabouts which in turn generates a wind. The introduced polluted air is purified by passing through the copper net 33, the silver net 34 and the hard charcoal/zeolite net 35, which are disposed within the air purifier. The purified air is discharged and then causes the magnetic rotary plates 5 to be rotated as shown in FIG. 2. As the magnetic rotary plates 5 are rotated, the blower 6 and the governor 7 installed above the magnetic rotary plates are rotated together therewith to increase the rotational force. Finally, the central shaft 13 operates the electric generators 10 so that the electricity is generated.
STORAGE SYSTEMS:
The hybrid energy-storage system(HESS) contains two supercapacitors of different sizes and a switching circuit. An adaptive-learning switching algorithm controls the switching circuit. This algorithm predicts the available source energy and the period that the sensor node will remain in the high-energy area. The algorithm dynamically switches between the supercapacitors according to available ambient RF, Vibration, Solar, EM and Thermal energy. Extensive simulation and experiments evaluated the proposed method. The proposed system showed 40% and 80% efficiency over single supercapacitor system in terms of the amount of harvested energy and sensor coverage.
In a HESS typically one storage (ES1) is dedicated to cover “high power” demand, transients and fast load fluctuations and therefore is characterized by a fast response time, high efficiency and high cycle lifetime. The other storage (ES2) will be the “high energy” storage with a low self-discharge rate and lower energy specific installation costs .
Main advantages of a HESS are:
Reduction of total investment costs compared to a single storage system (due to a decoupling of energy and power, ES2 only has to cover average power demand)
Increase of total system efficiency (due to operation of ES2 at optimized, high efficiency operating points and reduction of dynamic losses of ES2)
Increase of storage and system lifetime (optimized operation and reduction of dynamic stress of ES2)
Energy storage coupling architecture in HESS used in MEPAP:
The coupling architecture in MEPAP consists of two DC/DC-converters. Here the parallel converter topology is very common. The additional DC/DC-converter associated with the “high-power” storage is in charge of the voltage regulation of the DC-bus. It helps to operate the “high-power” storage in a broader voltage band, and hereby the available storage capacity is better utilized.
Frequency decoupling used in MEPAP is well suited for real-time applications. It is accomplished by a simple low-pass filter or by advanced filter concepts based on wavelet or Fourier transform. The low frequency component supplies the set-point value of the power controller of ES2, the high frequency component is covered by ES1.

Output power Usually, the outcome of a WPH system is DC power, which is characterized by load voltage VDD and current IDD. Measuring open-load voltage demonstrates the performance of WPH in general since VDD and IDD depend on load impedance. If the load is a sensor, VDD is more important than IDD while in applications like electrolysis or LED, current is the dominant parameter

R as:
Pr= PtGtGr (λ/4πR)2
where Gt and Gr are antenna gains, and λ is the wavelength of the transmitted signal. The received signal strength, diminishes with the square of the distance, requires special sensitivity considerations in the circuit design. Moreover, FCC regulations limit the maximum transmission power in specific frequency bands. For example, in the 900 MHz band, this maximum threshold is 4 W. Even at this highest setting, the received power at a moderate distance of 20 m is attenuated down to only 10 μW.

RESEARCH TEST FROM EXHAUST ENERGY(TEG MODULE)
Speed of the vehicle is the most important factor for the power generated by a TEG. For better Performance of TEG, speed of vehicle should be greater. As the exhaust temperature is higher, more energy is available for the conversion into electrical energy. There is increase in optimal length and reduction in optimal width based on dynamic optimization simulations when the Temperature of the exhaust increases.
The efficiency and power of a TEG remarkably depends on the temperature. Given figure shows the temperature of inlet and outlet when the engine is operated between 2500 rpm to 3400 rpm. As the engine speed increases, the temperature difference between the surfaces of TEM increases rapidly, hence the output power also increases.
It was found that there is a possibility of generating 1.4 kW of electricity form the heat recovery system in the exhaust of the car if the power produced by the engine is 150 kW and also found that it is possible to produce electricity of 5.9 MW by a waste heat energy recovery system of 500 MW of gas turbine power plant.
Another experiment has been performed for checking the power output of TEG by changing the speed of vehicle. The speed of the vehicle were 48.3, 80.6 and 112.7 km/hr and the result was the output power increased as speed of vehicle increases correspondingly mass flow rate of exhaust and inlet temperature increased as per the speed. At the speed of 80 km/hr, the power output with 72 mm * 4 mm TEM was 75 W.
Fig1. Variation in temperature due to variation in speed.
Fig2. Variation in power production.
TEG Power Generation Calculation:
The equation involved in calculation of the performance of a TEG is
Z = α2 / kR,
Z is a figure of merit of thermoelectric material, R is the electric resistivity
k is a thermal conductivity and
α is a Seebeck coefficient which is
α = ΔV / ΔT,
T ͞ is the average temperature of cold and hot plate of a TEM and when multiplied by Z it makes it Dimensionless.
ZT ͞ = α2 T ͞ /KR
And
T ͞ = (TH +TC ) / 2
As per the second law of thermodynamics,
ῃ = TH – TC / 2
The maximum efficiency of conversion of a TEG can be found using
The output efficiency of a TEG mainly depends on two variables: the temperature and MFR of exhaust. Maximum power output and corresponding heat transfer can be obtained by maximizing the
MFR ratio. As the size of a TEG increases, the output power also increases.
Street food is an essential part of the Indian culture and cuisine. There are a number of street foods from across the country that are famous, but nothing can beat the hot and crispy kachoris and samosas from Banaras or Varanasi. The holy city is situated on the banks of the river Ganges in the state of Uttar Pradesh and its food is defined by its culture and tradition. The food of Benaras or Varanasi is influenced by its people. You will find Marwari traders and people from nearby states including Bihar and West Bengal in the city have added their own regional touch to the local cuisine. The vegetarian delicacies are majorly prepared in desi ghee and mustard oil, be it spicy, sweet or sour. Most Varanasi sweets have a milk and ghee base like the Magdal, Sankat Mochan ke Laddoo, Parval Mithai, Kheer Mohan and Launglata among others.
1. Kachori Sabzi
Kachori sabji makes for the most popular Kaleva (breakfast) option in Benaras. There are two different types of kachoris- badi and choti kachori. Badi kachori is stuffed with masala made of lentils called dal ki pithi and choti kachori is stuffed with a spicy potato mixture. Both of these kachoris are savoured with garam masala wali aloo ki sazi and desi ghee jalebi. What a way to start your day!
2. Chena Dahi Vada
All the curd lovers raise your hands! Chena is similar to Rasmalai in terms of shape and is dipped in sweet yogurt and a hint of masala made of jeera and black salt. It makes for a perfect mix of sweet and sour. The coriander garnishing makes it more refreshing. A perfect dish to enjoy with your freinds and family.
3. Malaiyyo
Makhan Malaiyyo or Nimish is a popular winter street dessert that is influenced by Persian way of cooking. Milk froth is flavoured with saffron and cardamoms and garnished with pistachios and almonds. Served in purva or kulhads, this creamy froth will literally melt in your mouth.
4. Thandai And Lassi
Varanasi is a city that produces lots of milk and curd and therefore, you’ll find them in most of their preparations. Benarasi Thandai is made from seasonal fruit puree. Along with that, lassi is available at almost every other street shop from morning till wee hours of the night. It is served in a kulhad topped with Rabri and flavoured with rose essence.
Right to repair is a proposed legislation/movement that allows consumers the ability to modify and repair their own electronic devices.
Planned obsolescence is the practice when goods are manufactured with a pre-determined expiry date aimed at forcing consumers into repeat purchases. The term was first termed in the 1950s by American industrial designer Brooks Stevens. This practice was introduced in the advent of mass-produced manufacturing at the start of the 20th century. But the practice was not as severe and prevalent as it is in recent years. One of the recent changes in the product design has been to make the goods very hard for end consumers to repair.
For instance smartphones, a couple of years back had a user-replaceable battery but with more features crammed into the chassis of a phone. Manufacturers have not only made it unnecessarily difficult to replace the battery but also to even open the panels of smartphones. With the recent MacBook Pro releases, Apple has soldered the SSD (Solid State Drive) on the motherboard. The reasoning for justifying the soldering by Apple is better reliability and the thinness of the laptops. But there is also another aspect. Apple’s business model is about selling laptops and not upgrading the systems. Upgrading an SSD can be a potential loss for them and to counter that Apple might have decided to make the laptop non-upgradable. The problem is that even SSDs are definitely much more reliable than mechanical hard disks but SSDs still fail and combining them with the motherboard means that if one of the two fails, the whole system fails. This also makes it much more difficult for end-user to repair their laptop. It also becomes a problem for the third-party repair business to access the repairing of these devices. This is just one of the instances of how access to repair is being restricted by the manufacturers but various companies are attempting to follow similar practices with varying degrees.
With the introduction of newer and sophisticated technological components in electronic devices, it has become much more complicated to operate these modern devices. To reduce the access to repair these devices, manufacturers state that repairing the devices might violate their “Proprietary” rights. These repair limitations are a critical problem for not just the first owners but also for the second-hand/ used market. Due to proprietary information and diagnostics tools while evaluating a device. It has become difficult for third parties and end-user to even attempt the repair their own devices that they own. It took Apple the lawsuit to introduce the battery replacement program after the fiasco of the performance throttling issue on older iPhones. It clearly indicates that companies do not like it when consumers try to fix their products and companies deliberately try to reduce the user experience of older devices so that they can sell the newer models to maximize profits. With a monopoly on repair manufacturer’s intent is to lock down the user to the official service centers which can be significantly expensive than third-party service shops.
The right to repair movement intends to enact power into the consumer’s hands for the devices that they own. This means that consumers can open and modify everything they own. Also to root, unlock or jailbreak the software in their devices.

As mentioned in the previous section , its source code is freely downloadable and that also comes with the GPL license , you are free to follow the documentation available and customize so as to work with your unsupported hardware . This makes the Linux hardware independent .
Linux is Secure : Linux has proven , beyond doubt , the sound security level it offers . This security aspect is the key feature of Linux and its security model is entirely based on UNIX , which we all know is very robust and of proven quality . In Linux , security is not only restricted to the security from internet threats but it is also very much secure from other system related breaches or malpractices . Linux offers security at all levels , such as User level , Application level , System level , Device level , Inner threats , External threats .
Linux is Scalable : When Linux was in the gestation process , its creators wanted to make an operating system that was extensively suitable for any application , any hardware , and any process . They wanted it to work with computers with high power and capacities like of super computers , mainframes , and with computer for personal use like PCs , laptops and even with computers of limited resources like Palmtop , PDAs , etc., so that Linux fits everywhere .
On July 11, Virgin Galactic will make a giant leap toward commercial suborbital spaceflight. The company will launch its first fully crewed flight of its SpaceShipTwo space plane Unity with a special passenger on board: the company’s billionaire founder Richard Branson.
Branson, three crewmates and two pilots will launch on the historic flight after being carried into launch position by Virgin Galactic’s carrier plane VMS Eve. They will take off from the company’s homeport of Spaceport America in New Mexico, with a live webcast chronicling the flight. Here’s everything you need to know about the mission, which Virgin Galactic has dubbed Unity 22.
WHAT TIME IS VIRGIN’S GALACTIC LAUNCH & AND CAN I WATCH?
Virgin Galactic has not released a specific time for the actual Unity 22 launch, but the company has announced it will begin webcasting the mission at 9 a.m. EDT (1300 GMT). And it looks like it’s going to be fun. The crew will walk out to the ship about an hour earlier.
Stephen Colbert, host of The Late Show on CBS, will host the webcast along with singer Khalid (who will debut a new single during the launch), former Canadian Space Agency astronaut Chris Hadfield and future Virgin Galactic astronaut Kellie Gerardi, who will launch on a research flight in 2022.
The webcast will begin with the Unity spacecraft and its carrier plane taking off from its runway at Spaceport America, which is located 55 miles (88 kilometers) north of Las Cruces, New Mexico.
Branson has stated that the entire flight will take about 90 minutes, including the ascent up to launch position, release, flight to space and glide back to Earth for a runway landing at Spaceport America.
Virgin Galactic will launch six people on the Unity 22 flight, although the spacecraft is designed to carry up to eight people (two pilots and six passengers).
Unity 22’s crew includes four mission specialists:
Sirisha Bandla, Vice President of Government Affairs and Research Operations at Virgin Galactic. She will evaluate the human-tended research experience via an experiment from the University of Florida that requires several handheld fixation tubes to be activated at various points in the flight profile.
Colin Bennett, Lead Operations Engineer at Virgin Galactic. He will evaluate cabin equipment, procedures and the experience during the boost phase and weightless environment inside Unity.
Sir Richard Branson, founder of Virgin Galactic. Branson will evaluate the private astronaut experience. He will receive the same training, preparation and flight as Virgin Galactic’s future ticket-buying astronauts and use the flight to fine ways to enhance the experience for customers.
Beth Moses, Chief Astronaut Instructor at Virgin Galactic. She will serve as cabin lead and test director in space. Her tasks include overseeing the safe execution of the test flight objectives. Moses has launched on Unity before.
Two veteran Virgin Galactic pilots will be at the helm of Unity during the launch. They have both launched to space on Unity before and are:
Dave Mackay: Mackay is Virgin Galactic’s chief pilot and grew up in the highlands of Scotland. He is a former Royal Air Force pilot and flew for Branson’s airline company Virgin Atlantic before joining Virgin Galactic.
Michael Masucci: Michael “Sooch” Masucci is a retired U.S. Air Force colonel who joined Virgin Galactic in 2013 who racked up over 9,000 flying hours in 70 different types of airplanes and gliders during more than 30 years of civilian and military flight.
Two other pilots will fly the VMS EVE carrier plane that will carry SpaceShipTwo into launch altitude. They are:
Frederick “CJ” Sturckow: A former NASA space shuttle commander who joined Virgin Galactic in 2013 with Masucci. A retired Marine Corps colonel, he was the first NASA astronaut to join the company and flew four space shuttle missions.
Kelly Latimer: Latimer is a test pilot and retired lieutenant colonel in the U.S. Air Force who joined Virgin Galactic’s pilot corps in 2015. She was the first female research test pilot to join what is now NASA’s Armstrong Flight Research Centre.
The primary objective for Unity 22 is to serve as a test flight for future passenger flights by Virgin Galactic. As its number suggests, this will be the 22nd flight of Unity, but only its fourth launch to space.
The four mission specialists will each evaluate different experiences that Virgin Galactic has promised its future customers, many of whom have already reserved trips to space with the company at $250,000 a seat.
Bandla, for example, will test the experience of performing experiments aboard Unity during different phases of the flight, including the weightless period. Branson will take note of the flight as a paying passenger to look for ways to enhance the trip for ticket holders looking for the experience of a lifetime.
Moses is Virgin Galactic’s Chief Astronaut Trainer and will ensure everyone is safe in their tests while Bennet will examine Unity’s cabin performance to look for potential enhancements.
This mission is a critical flight or Virgin Galactic, which Branson founded in 2004. VSS Unity is the company’s second SpaceShipTwo after the first, VSS Enterprise, broke apart during a 2014 test flight, killing one pilot and seriously injuring another. Virgin Galactic has made numerous safety upgrades to prevent such an accident from happening again.
The mission will begin with takeoff from Spaceport America, where Virgin Galactic has built its “Gateway to Space” terminal to serve its future customers. The crews of Unity and Eve will walk out to their vehicles at about 8 a.m. EDT (6 a.m. local time, 1200 GMT). They’ll be wearing custom Under Armour flight suits made for Virgin Galactic.
After takeoff, the carrier plane VMS EVE will haul the SpaceShipTwo VSS Unity (short for Virgin Space Ship) to an altitude of about 50,000 feet (15,000 meters), when it will drop the the spacecraft.

After separation, Unity will ignite its hybrid rocket motor, which uses a mixture of solid and liquid propellant, to begin the boost phase. This will carry Unity to its target altitude above 50 miles (80 kilometers), where the pilots and crew can expect up to 4 minutes of weightlessness. They will exist their seats and enjoy sweeping views of the Earth below through the many round windows that dot the space plane’s fuselage.
After that short encounter with weightlessness, the crew will climb back into their seats as Unity prepares to return to Earth. Pilots Mackay and Masucci will have “feathered” the spacectraft’s twin tail booms to provide stability during atmospheric reentry.
The feathered tail will then be locked back into place for the glide back to Earth, which will end with a runway landing at Spaceport America. The entire flight, from takeoff to landing, should last about 90 minutes, Branson has said.
WILL VIRGIN GALACTIC REALLY REACH SPACE WITH UNITY 22?

Virgin Galactic will launch Unity to an altitude above 50 miles (80 km), which NASA, the Federal Aviation Administration and the U.S. military classify as space. They will earn astronaut wings for reaching that height.
Another widely recognized boundary of space, the Kármán line, is at an altitude at 62 miles (100 km) above Earth. The SpaceShipTwo VSS Unity won’t reach this milestone, which has led Virgin Galactic’s competitor Blue Origin (which does fly higher than 62 miles) to call out Virgin Galactic for missing that mark.
WHERE DOES VIRGIN GALACTIC LAUNCH SPACESHIPTWO FROM?

Virgin Galactic initially launched SpaceShipTwo test flights from the company’s facilities at Mojave Air and Space Port in California. However, in 2020 the company moved Unity and its carrier craft to its permanent home at Spaceport America, where it plans to fly regular passenger flights beginning in 2022.
Spaceport America is located near Las Cruces, New Mexico and is home to Virgin Galactic’s “Gateway to Space” terminal, a welcome center and waiting room for ticketed passengers preparing for trips to space. It also sports a large hangar designed to fit multiple SpaceShipTwo spaceplanes and the VMS Eve. Virgin Galactic has also built a new vehicle, the SpaceShip III VSS Imagine.
WHEN COULD I LAUNCH TO SPACE WITH VIRGIN GALACTIC?
If you booked a trip with Virgin Galactic early and have one of the first reservations, you may get your chance to fly in space as early as 2022. If not, there’s a long wait ahead. And that’s assuming you can afford the $250,000 ticket price.
Virgin Galactic has said it plans to begin passenger launches in 2022 after a series of final test flights in 2021. The company does have hundreds of reservations for customer flights in backlog from eager would-be astronauts that have been waiting for over 17 years (since Richard Branson first announced Virgin Galactic in 2004) for the SpaceShipTwo to finally fly. The company paused taking new reservations after the 2014 accident.
Virgin Galactic is expected to resume taking reservations for “a limited number of tickets for future spaceflights” sometime this year, according to its website.
The world has just started recovering from the deadly Covid-19 virus, even though it is a thing to be happy about, there are still sectors that are trying to rise including the entertainment industry (movie productions, theaters, film cities) from the hard hit by the pandemic.
