FYI... People ARE developing it. It's expected to be used to charge small devices... I'm sure they'll improve the distance after a while... :)
A link is below...

Edit: Here's another link...

Some quotes from the site:
Most of the charging pads employ the principles of inductive coupling, which transfers energy from a transmitter to a receiver using a magnetic field. In devices like electric toothbrushes, a coil of wire in the transmitter (or charging base) creates a magnetic field that "induces" an electrical current in a second coil of wire in the toothbrush handle, which is connected to a rechargeable battery.
By adjusting the frequency at which the magnetic field resonates, the charging pads can send more or less power to a given device, or send power across a distance of a few inches (today's toothbrushes, to recharge, must sit firmly in their base station.)
A wild card entrant in the wireless power race is a team of Massachusetts Institute of Technology researchers led by Professor Marin Soljacic. In June, it demonstrated longer-range power transfer, using a magnetic field to light a 60-watt bulb seven feet away. The team, which dubbed its technology WiTricity (and received a trademark on the term), said it could eventually fill a room with enough power to safely charge laptops or other devices.
Looks like wireless power is coming soon...

It's called a microwave oven. Just screw on a waveguide and a suitable dish. You will achieve remarkable results in short time.
Just don't stand in the beam.
I SAID, DO NOT STAND IN THE BEAM!
And that is the the real problem with wireless electricity... no matter at what frequency you transmit, with any technically useful power levels biological systems get burned, cooked or harmed otherwise.
Ship radar is known to have health effect. So are radio transmitters. Ever seen an FM transmitter in the forest? The tree branches right next to the antenna are dry and dead. And they put up a fence and a warning sign for a reason. There are dangerous voltages, currents and em field close to those facilities.
So, the answer is, yes, there will be wireless electricity, as soon as we learn how to make living beings out of glass or plastic.

No way. Electricity cannot safly move in air. It would be extremely unsafe, unpractacle, and unprodicable. It's best to stick with wireing when it comes to electricity. But signals, like TV, Radio, IR, that can go wireless.

Nikola Tesla worked for years on this possibility. He was not very successful. I think someone will continue his work and solve this problem; but to answer your question at the present time there is no way to flow power with out an conductor.

I trust Kenn N. The battery desires to be exercised by way of being run down & then recharged, protecting in a relentless state of being charged will develope a "memory"; f'rinstance, in case you recharge a battery while it somewhat is basically discharged 10%, finally it is going to basically settle for a ten% charge. some laptops, certainly maximum, so some distance as I keep in mind, would be run on mains without the battery in - that must be the respond for capability-hungry apps like video games & streaming video. i might seek for a clean battery, supply it an entire charge and in destiny basically use it while out & approximately. and then run it genuine down formerly recharging.

It's possible in limited ways but air is not a very good conductor which is required for efficient transmission and distribution of power.

No, all electrical currents must have a grounded source.... If not it would be like lightning striking somewhere, once it hits the ground the current is dead

radio communications IS wireless electricity.
If you mean wireless POWER, it will never replace wires, as it is too dangerous, inefficient and impractical, regardless of what Tesla and the conspiracy whackos say.

Yes, along with free universal medical care. It will work by the real voodoo economics.

try by solar power or by wind power..
