The most successful application and conclusion ( Team )

# data[].attributes.body
Our team after a lot of brainstorming sessions have reached the conclusion that the concept of inductive charging presently being used in smartphones

Finally i would like to conclude that Wireless transmission of energy is a technique that holds a strong potential. It promises to change the face of the technologies in transmission of power. Its applications can be huge. In future there are possibilities that power can be transferred over large distances without affecting the environment. Using varies theories described above; electrical energy can be transferred to remote terrains. Another important issue being use of batteries can be reduced; replacement and recharging batteries would not be required. Use of wireless technology also saves on the resources spent on wire. Laying a wireless network would be much simpler than struggling with wire in difficult terrains. The technology technique in future.also promises to be eco friendly in comparison to today’s technologies. Hence all in all wireless transmission of energy could be the key power transmission

The article posted describes the various fields where wireless electricity can be and will be used to create a hassle free network of power transmission.

The article by Witricity, one of the leading pioneers in wireless power transmission demonstrates the various fields where wireless electricity will dominate in future.

Be it electric cars, devices using inductive charging or power transmission over long distances, wireless power transmission will not only make power cheap but its transmission would be simplified and electricity could be made available more easily.

Broadly speaking there are two major forms of wireless power transmission:

1. Radiative, for long distances.

2. Non radiative, for short distances .

Though wireless electricity has been developed greatly, it still has a long way to go before it becomes commercially viable.

Much of it thus remains only at theoretical level and is yet to be put in practical use

For collecting the data first I referred to our campus library but didn’t find substantial data so this forced me to move towards Internet then I surfed internet for authentic data sources like some research papers, journals, TED talks and so many sources. Luckily I found a TED talk by Eric Eiler the CEO of MIT-inspired WiTricity and a research journal on uses of Wireless Power Transfer in Biology.

# data[].attributes.body
It is very clear that in this energy hungry world one cannot carry strings everywhere and every time with him/her so to reduce this necessity of carrying burden we invented Wireless Energy Transfer Mechanism. Wireless Power Transmission is a new and vast concept having various applications. Some examples are  :

Microwave Power Transfer

Electronic portable devices

Electric Vehicles

Theoretical applications: Aerial Vehicles and Solar Power Satellites

Making conclusion we can say that this is a revolutionary technology and even can change the world

 How i collected data???( Mayank Agrawal )

# data[].attributes.body
Wireless Electricity is a new technology. Many people are still not aware of such a technology. Therefore i faced a lot of challenges in collecting data.

First of all i want to the campus library but there was no book or any journal directly related to the topic.

Since nobody knew much about it i had to resort to internet. Then I researched on internet. I found that the idea was first drawn up by Nicola Tesla. Then i went to the website of Nicola Tesla Society. After that i read articles relating to Tesla. The second doc and answers have been taken from these sources.

After that i searched e-journals like IEEE. But found nothing convincing. After that i read the international physics journal on wireless electricity. It was very comprehensive and therefore the main doc has been taken from there.

Q 1.What were the other concepts used to produce wireless electricity???( Mayank Agrawal )

# data[].attributes.body
One British inventor, H. Grindell-Matthews, actually demonstrated his "mystery ray" apparatus in 1924 to a Popular Science Monthly.When his beam was directed toward the magneto system of a gasoline engine, it stopped the system. Afterwards, it ignited gun powder, lit an electric lamp bulb from a distance and killed a mouse in seconds! Grindell-Matthews said the secret was involved with the "carrier beam" he used to conduct a high-voltage, low-frequency electrical current. During 1936, Guglielmo Marconi experimented with extremely low frequency (ELF) waves and displayed their exceptional ability to penetrate metallic shielding. These waves could affect electrical devices, overload circuits and cause machines like generators, electric motors and automobiles to stall. Diesel engines, which do not rely on electrical ignition, were not affected. Mysteriously, Marconi's research on the subject was never found after the war.

Q 5.What is Tesla coil? And how it is linked to wireless electricity?. How can these coils help in overcoming the shortage of electricity ??? ( Mayank Agrawal )

# data[].attributes.body
A Tesla coil is a special transformer that can take the 110 volt electricity from your house and convert it rapidly to a great deal of high-voltage, high-frequency, low-amperage power. The high-frequency output of even a small Tesla coil can light up fluorescent tubes held several feet away without any wire connections. Even a large number of spent or discarded fluorescent tubes (their burned out cathodes are irrelevant) will light up if hung near a long wire running from a Tesla coil while using less than 100 watts drawn by the coil itself when plugged into an electrical outlet! Since the Tesla coil steps up the voltage to such a high degree, the alternating oscillations achieve sufficient excitations within the tubes of gases to produce lighting at a minimal expense of original power! Fluorescent tubes can be held under high-tension wires to produce the same lighting up effect.

Using a Tesla coil, high voltage AC can light up glass-enclosed vacuum bulbs coolly without any

gases inside them at all! Any number of cold light bulbs can be lit using only one Tesla coil, and since there is nothing inside them to burn out, they can last indefinitely. It seems like a low cost form of street lighting, doesn't it? In this manner it can overcome the shortage of power and can lit each and every corner of this world .

Tesla after inventing Alternating Current (A.C.) sold it's rights to George Westinghouse for $1,000,000. He used this money to pay off his prevoinvestors and to continue his work on other inventions including wireless electricity.

After successfully demonstrating the concept of wireless electricity J.P.Morgan agreed to fund him.

Q 2.How did Tesla proved the concept of wireless electricity a success???( Mayank Agrawal)

# data[].attributes.body
Tesla got a major breakthrough in 1899 at Colorado Springs by transmitting 100 million volts of high-frequency electric power wirelessly over a distance of 26 miles at which he lit up a bank of 200 light bulbs and ran one electric motor! Tesla claimed that only 5% of the transmitted energy was lost in the process which is much less than transmitting power through wires. Thus showing that the experiment was a success.

Resonant inductive coupling between two coils to transmit energy between them by Abhyuday.

# data[].attributes.body
Wireless power transfer is a generic term that refers to various methods of transferring energy using electromagnetic induction. Inductive charging is a form of wireless power transfer. It is currently used in high end smartphones e.g. Samsung Galaxy S6.

A very basic form of wireless electricity is shown in the video. It is based on Faraday's law that change in magnetic flux induces an emf in the circuit which is proportional to the change in magnetic flux.

The transistor turns current on and off in the circuit which in turn causes changing magnetic flux and thus induces an emf in the other circuit thus transferring current from one coil to another without wires.
