Slightly OT.
        I remember from a long time ago, seeing an way of getting low power
from thin air. You need a circuit resonant at the frequency of your local AM
transmitter, an antenna and earth and a rectifier tapped into the coil.
Instant free energy. With the low power requirements of a PIC it just might
be possible!(When I tried it I found I needed a longish wire antenna - but I
also needed several milliamps)

Anyone else tried this?
