Just long enough for Apple to make it look like a little ipod.

Scientists have not 'found' wireless electricity. Tesla thought of the idea back when he wanted to install giant emitters to broadcast free energy. The problem was, and still is, the diffusion of electric fields, and that they decrease in strength rapidly with increasing distance. Yes, scientists have recently found ways to improve this efficiency, but only to the point so far that we could power small appliances from several feet away, such as charging a laptop with a remote charger under your desk.
A car powered by wireless electricity? I think we'd more likely develop cars that run on Higgs particles before that.

In order to conduct an electric current(electrical power) a medium is required. Just like a medium is required to carry the power of light radiation.
Without a medium it is imposible to transfer power of any kind,in this Universe by natural means.
Electrical waves are transmittted thru a conductor which is usually a metal.
Power of electricity can be transfered thru the air by means
of ionization of air molecules. However this occurs basically thru lightning a process that take so many millions of volt.
It Just would not be practical or safe for a power company to manufacture.
In a thunderstorm lightning thru the air would fry anything on its way. In the microworld of electricity electronic power has been produced by thermionic emission.This occurs in the electron tube.

They won't. The amount of power they transferred was only enough to charge a cell-phone battery. They were looking for a way to eliminate all the various tiny power supplies that you use in your home to charge and power various devices. None of them use more than a flashlight's worth.

To get substantial amounts of power through the atmosphere would require electric fields so strong that they'd break down the insulation of the air, yielding those sparks that you see around a Tesla coil. The power wouldn't go anywhere.

The solar power satellite might work, but it sends power over microwave beams which really screw up communications.

the concept of transmitting power to a vehicle from the road is far from original, trams for example take their power from overhead lines.

A reasonable design would be a vehicle which picked up power by inductance from the road surface, this should still have enough batteries to allow it to drive for a few miles in case of a local power failure.

Now all we need to do is spend billions of £ or $ to refit all road surfaces to allow this type of vehicle to run....

Problems with using "wireless" electricity transmission:

Setup cost - who pays for the transmitters?

ongoing cost - once you are transmitting power how do you ensure that the person recieving it is paying you for it instead of just picking it up for free?

Wireless car?

What exactly would a Wireless car be?

Yea, its the only drawback of the electric car, the 50 mile extension cable

Tesla was using the ground wave.Big difference in propagation.
