Wireless electricity is one of the most emerging solutions to the global power crisis. It is defined as the transfer of wireless electricity or power from a source to a load without the use of any artificial interconnecting conductors such as wires. Wireless electricity is being used primarily on the basis that at times, wires can be inefficient (power is lost as wires transmit electricity over long distances), inconvenient (in terms of cost and labor) and sometimes hazardous (many people may be electrocuted or put in some sort of danger).
Our team paid attention to two different forms of wireless energy transfer- the first is through resonant inductive coupling, whereby energy supplied to a coil is transferred to a similar parallel coil without the use of any wires in order to provide enough electricity to light LED’s (Light Emitting Diodes). The second is through the use of a laser that reflects onto a solar panel attached to a capacitor that stores the energy converted by the solar panel, and transmits it to an LED placed at a distance. This time, the LED is connected through wires as the laser already shows the transfer of wireless energy. Other forms of wireless electricity transfer not looked at include the use of microwaves etc.

Wireless power transmission is not a new idea. Nicola Tesla demonstrated transmission of electrical energy without wires in early 20th century. Tesla used electromagnetic induction systems. Tesla discovered that electrical energy could be transmitted through the earth and the atmosphere. In the course of his research he successfully lit lamps at moderate distances and was able to detect the transmitted energy at much greater distances. The Wardenclyffe Tower project was a commercial venture for trans-Atlantic wireless telephony and proof-of-concept demonstrations of global wireless power transmission. The facility was not completed because of insufficient funding.
Earth is a naturally conducting body and forms one conductor of the system. A second path is established through the upper troposphere and lower stratosphere starting at an elevation of approximately 4.5 miles.
A global system for "the transmission of electrical energy without wires" called the World Wireless System, dependent upon the high electrical conductivity of plasma and the high electrical conductivity of the earth, was proposed as early as 1904
Following World War II, which saw the development of high-power microwave emitters known as cavity magnetrons, the idea of using microwaves to transmit power was researched.
William C Brown demonstrated a microwave powered model helicopter in 1964. This receives all the power needed for flight from a microwave beam. In 1975 Bill Brown transmitted 30kW power over a distance of 1 mile at 84% efficiency without using cables.
Japanese researcher Hidetsugu Yagi also investigated wireless energy transmission using a directional array antenna that he designed. In February 1926, Yagi and Uda published their first paper on the tuned high-gain directional array now known as the Yagi antenna. While it did not prove to be particularly useful for power transmission, this beam antenna has been widely adopted throughout the broadcasting and wireless telecommunications industries due to its excellent performance characteristics.
In 2006, more recent breakthroughs were made; using electrodynamics induction a physics research group, led by Prof. Marin Soljacic, at MIT, wirelessly power a 60W light bulb with 40% efficiency at a 2 meters distance with two 60 cm-diameter coils.
Researchers developed several techniques for moving electricity over long distance without wires. Some exist only as theories or prototypes, but others are already in use.

so i did it for you. your welcome.
"But oil resources offer only a glimpse of the full picture. As I noted earlier, CRS found that America’s combined recoverable natural gas, oil, and coal endowment is the largest on Earth. It’s far larger than that of Saudi Arabia, China, and Canada combined."

I love how you are doing this type of research. I think there is some severe positive implications and results than can happen from it! Best of luck!
As for the claims, they are all baseless. In order to know the end of something, you have to know the total of it. That just isn't happening. Noone knows how much of any amount of minteral/substance there is in the whole world. Period. A ludicrous claim by people who want to promote an agenda.
That being said, I think Oil is a doomed tech simply because it is inefficient (I believe the number is something like 25% of actual usable power from internal combustion engines?).
People also either have forgotten, or simply not bothered to look but the first cars made were actually electric cars (re: The Electrobat).
As for ancient technology, peopel who say it never happened are the people I want to see proof they were actually there. It is a shame that people simply close their minds to possibilities. New ideas and proofs pop up all the time, disproving previously preconceived notions of 'what was'.
Manish, I look forward to seeing what else you come up with :)
Now if we're all gonna get picky, the car is attributed to being patented by Luigi De Cristoforis in 1876. The first GASOLINE Carb was done by Enrico Bernard I in 1882.
The first electric motor is attributed to Anyos Jedlik. The first electric vehicle (train) was created in 1842. The first electric two wheel cycle was displayed in 1867 World Exposition.
I am not concerned about commercial/retail. Electricity was in people's minds before gas. That is the point.
It depends on what you mean by "car". I found this page, which I found informative: http://www.ausbcomp.com/~bbott/cars/carhist.htm
My understanding of the first Mercedes Benz (considered by some to be the first car) was that the fuel was vaporized in a externally heated tube. Thus, it didn't have anything resembling a carburetor. I admit that my recollection may be faulty.
I believe that we ended up with the (mostly) gasoline-powered ICE simply because that is the best solution. While there is some disagreement on the exact number, a gallon of gasoline is the approximate energetic equivalent to 36,650 watt-hours. Even at the efficiency level you cite (and the attendant higher efficiency of electric motors), that is an advantage that is quite difficult to overcome.
At the present, state-of-the-art technology, it takes a $40,000 battery to take a car any appreciable distance, without being recharged in some fashion.
Yes, I know that Chevrolet Volts don't cost that much to the consumer (aside from the debate as to whether 40 miles is an "appreciable distance), one commentator added up all the upstream, government subsidies of the volt, and they amounted to $50,000 to $250,000 PER CAR, depending on production, which hasn't been much (the production line has been temporarily shut down due to lack of demand).
