Just ran across an ad where a photocell panel was advertised for $100. It didn't give any specifics about how much juice it would put out, but got me thinking about how hard it would be to make one. I think it takes silicon and phosphorous crystals, or perhaps a lazer.
Wondered if anyone has thought about, or does generate their own electricity. What method they use, I read a little a long time ago about solar cells, batteries, windmills, and a guy who lived on a cattle farm that got his fuel to run generators and tracters off the methane he produced by putting cow patties in a silo.
Anyone thinking or have any practical experience along these lines?
