Have a look at these videos.
Very interesting !

Also here is one interesting wireless power transfer:

Here is a link to Marin Soljačić's work in transmitting power wirelessly at MIT.

Tesla demonstrated the same kind of technology in 1899.

I was always wondering if one put a tesla coil in the middle as a transmitter and couple 4-5 others around will all the outside coils power their own light bulbs the same?
And if yes is the power input in the transmitter the same?
If the answer is yes to both then the aether it behaves like an incompressible fluid and all vibrations are transmitted all around with same intensity no matter how many receivers you have

wireless power concept seems very simple even over long distances....

If you point two speakers at each other it will transfer the sound waves to the other speaker.

The receiving coil in the speaker will then turn it back into usable energy that it received from the sound waves hitting the cone.

Now from what i have seen they have speakers that you can pin point like a laser beam that let sound waves travel at long distances without breaking up

I do not know if its ever been tried but it sounds like it may work as long as the path for the sound stayed clear!

There's something I've been wondering about, with these wireless Tesla transmitters.  If the bottom of the transmitter secondary (not primary!) is connected to the bottom of the receiving coil (creating a common ground point), does that affect output power?  Has anyone tried this?
