 Goodbye wires…MIT team experimentally demonstrates wireless power transfer, potentially useful for powering laptops, cell phones without cords. Imagine a future in which wireless power transfer is feasible: cell phones, household robots, mp3 players, laptop computers and other portable electronics capable of charging themselves without ever being plugged in, freeing us from that final, ubiquitous power wire. Some of these devices might not even need their bulky batteries to operate. by Franklin Hadley, Institute for Soldier Nanotechnologies June 7, 2007 -------------------- |

There has GOT to be more here than the layman articles are saying as this is nothing new. It's simply a resonant air-core transformer. One article I saw indicated 40% efficiency. That's *terrible*.

Am I missing something? I don't read anything that indicates progress beyond Nikola Tesla's experiments of a hundred years ago.
I also missed an indication of operating frequency. The article just says that it operates "at MHz frequencies". That's a mighty big range -- presumably from 1 Mhz to 1 GHz. Is this a case of poor reportage of a brilliant breakthrough, or does the experiment itself demonstrate nothing new? This post has been edited by Russ Bellew: Jun 8 2007, 04:39 PM |

It's got to be in the low-MHz range. Once they get out of near field, their 'magnetic wave' rapidly becomes ordinary electomagnetic - which they indicate is no good. Higher frequencies would mean getting into far field quicker.

Has anyone seen the thing on "thinkgeek.com" about the wireless power cords? They use microwaves and has a range of what 200ft?
I wish they could do wireless power because with it we could change the car industry forever. With a good efficiency. Not to mention it might get me to buy one of those wireless mice ha ha.

I dont believe it, well I dont believe it is possible to transfer power without wires without posing a danger to people in the same room, what about pacemakers? I just dont think this is a very good idea.
