We used to make them with a razor blade, wire wrapped around a cardboard tube and a piece of pencil lead on a safety pin. They were called the Fox Hole radio.
You can use the same idea for power instead of radio. Its called a rectenna. Hook up a dipole antenna to an antenna to coax adapter. Connect that to a germanium diode and then the diode to the ground. Enjoy your free power.

I was in the Canadian army from '69-'72. We built those Fox Hole radios when I was in grade 5 or 6. I think you can still find the plans online.
