Robin, it would be very impractical to attempt to tap into the 60 hertz field with a device of this size. They had better stick with the high RF frequencies.

No, you just need to use resonance, though I grant that a resonant circuit at 50 or 60 Hz would probably need large capacitors/coils. Using electronics to mimic a coil using a cap, would probably waste too much energy. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
