I'm sure they are evaluating the impact. One of the things they must be doing is very precise load characterization to prevent house fires (put a non-compatible device on top and it might not only get cooked, but overheat enough to start a fire). So they not only test to make sure that a valid load is present before turning on the high power coils, but they probably also test to make sure that _only_ the correct load is present. Feedback between the power supply and powered device can find if too much energy is being leached into some other device. However, it will likely always be a "people with pacemakers and other medical devices or implants (insulin pumps, metal plates or pins, etc) should not come near to the device." The kicker is that I don't see a great need for this. It looks cool, and there's a certain high end market for this sort of device, but moving power a distance shorter than 6 feet (length of a power cord) isn't terribly useful. I can see it for recharging portable devices which are cumbersome to plug/unplug (palm pre has this, for instance) but for items which are typically put in place and never moved there are far cheaper and more efficient ways to get electricity and signals to them in a hidden manner. -Adam On Tue, Oct 13, 2009 at 5:15 AM, Vladimir wrote: > Hi all, > > I`m completaly dummy on this subject.
