Wireless Energy Lights Bulb from Seven Feet Away

Posted June 07, 2007 8:36 PM

From Scientific American - Official RSS Feed:

If you thought wireless Internet made life convenient, try wrapping your mind around wireless power. Researchers have successfully lit a 60-watt light bulb by transferring energy through the air from one specially designed copper coil to the bulb, which was attached to a second coil seven feet away [see image at right]. The ultimate goal: to shrink the coils and increase the distance between them so that a single base station emitting "WiTricity," as the inventors refer to the effect, could power a roomful of rechargeable gadgets, each containing its own small coil.

One bickering problem though, to this age old quest:

Let's say you (we) manage to create this ideal long-distance high-power system. What of someone or something blocking the path of the beam. Roasted to crisp?

Isn't it more practical with an insulated conductor of some sort?

It's like this Transcendental Meditator who told my ex-wife of their latest endeavour to maintain this all-new flight-position, hovering in mid-air. She replied: Isn't it easier and cheaper to just rent a helicopter?

The EM field will pass through mostly anything, but anything it passes through will be unharmed. I'm not impressed, though, because as much as I admire the work of ambitious MIT students, they're reinventing the wheel. Nikola Tesla came up with a similar system 100 years ago, but his system was designed to wirelessly provide power to the entire world with only a handful of strategically located broadcasting stations.

...IIRC Nic was using ULF radio, the current (oops) problem is that Wi-fi is interfering with genetic switching, cell (not cellular) level biomechanics and function with no data on the potential harm this may have on paediatric neurological development.

Certain official ostrich policies are still adhering to the issue of the thermal effects of microwave radiation as a means of establishing 'safe' standards -as long as the public are unaware of the danger. "If it isn't working, don't fix it" I think is the well trodden in phrase.

Big words don't mean things will turn out for the better.
