Crystal radios are great projects to do with your kids, too.
The high impedance earphones are getting a little hard to find, though.

Instead of a crystal radio, make a rectenna. Same concept but its used for energy instead of radio
Is that what they used to call a joule thief?
im not totally sure what a joule thief is but ive seen them on youtube used alongside crystal radios.
a joule thief steals energy from the air?
If I remember correctly, it's based on a transformer to up the voltage from the EM hash in the air that's being emitted by all of our technojunk.
Its an induction coil. Not a transformer. A transformer will use up the current.
