I think it was in the news sometime ago that MIT thought it should be possible to power a laptop computer through the air waves. Here's an example in reverse where five aluminum winds around a closed lap top pick up a 40 VAC 60 hz signal. Actually it is a square loop antennae consisting of 5 winds in series with a capacity to lower what would normally be a much higher frequency signal reception between The probe is set on 10 x and the volts per div at 2, showing a 40 volt signal. http://www.youtube. com/watch? v=YRmfHfCYPAc Heres one showing high frequency reception from twin sized series ferrite toroids, picking up EM from both a florescent lamp and the laptop computer. http://www.youtube. com/watch? v=pLEBH04Fi3Q Sincerely HDN Pioneering the Applications of Interphasal Resonances http://tech.groups.yahoo.com/group/teslafy/
