Wireless Power Gets A Boost

Wrong era for this technology

[Rorian]

This stuff would (perhaps) have been really neat 10-20 years ago. Now we really need to start thinking hard about saving power in every way possible way (Global warming and all that..), and creating a technology that is only ~40% efficient (last time I looked) is NOT the way to achieve that, even for small, low-power devices.

Great idea, don't even consider bringing it to mass-market, unless you're bringing fusion power as well.

Potential danger

[Chris whatever]

what i'm wondering is how large is the magnetic field that this induction device do? They are still looking at the possibility that the magnetic fields created by power lines may create problem like cancer and stuff. We already have a screen and other low emitting devices in our offices and they are considered dangerous, what if we have something that emit a larger magnetic field for recharge? I guess it would have to be powerful enough to recharge a battery in a acceptable delay or to just be able to make the recharge possible. Or maybe they already found a material sensitive enough that react with low electrical emission? Anyways, wont see me recreate the Manhattan project in my office ;)
