Small electronics draw relatively little power. You can run a small LCD/LED TV (or radio) off solar PV and a small (regulating) battery. Large power (and heat) loads require far more (and more reliable) energy. Tapping into human energy is an option, though net net it's still fairly inefficient.

Well, electricity is made out of rotating things if you strap a magnet to them somewhere ;).

If you're powering a washing machine and a TV by pedaling, I'm not sure you'll last a full cycle ;)

ha! good point.

Although I was kind of thinking that even without the electricity, it's a benefit.

Or alternatively, you could get 20 of these, all facing each other and be sociable. Or if you have some electricity in a town, get all of them in a hall, and play movies. :-)
