"If you bring another resonant object with the same frequency close enough to these tails then it turns out that the energy can tunnel from one object to another," said Professor Soljacic.

Wireless energy transfer has been thought about for centuries

Hence, a simple copper antenna designed to have long-lived resonance could transfer energy to a laptop with its own antenna resonating at the same frequency. The computer would be truly wireless.

Any energy not diverted into a gadget or appliance is simply reabsorbed.

The systems that the team have described would be able to transfer energy over three to five metres.

The problem is that it takes a lot of power with a big antenna for it to work.

The mythbusters tried this thing and they only got a couple volts out of a huge high-tension line.

I dunno if I would want that.. its good and all, it seems like it might be too many unknowns about that technology, and unknown long lasting effects of standing in between the energy transfer either..

that would probably be unwise to stand in the energy beam, but an array of dishes set up to recieve power from an orbital fusion plant or very large solar panel array might work...

Might make a good fence to keep out tresspassers. A to B by transmission. B to C (which is adjacent) by wire then on to D by transmission. Anyone between transmitting antennas gets jolted (or fried if you have enough power).

That would make it an excellent weapon. Put a microwave in orbit, aim it at the middle east, and set it to potato and our problems are solved.

Or should we use the popcorn setting?

A hacker with metal tooth fillings could intercept all your vital data...

... of course, it the beam is high enough intensity, it'd fry his mouth...
