Solar charging

[gfish]

Turns out my dad has a nice 10 watt folding solar panel that I can borrow. (I really shouldn't be surprised.) So the cost for charging digital camera batteries just went from $120+ to $8.92 for a 12v charging unit. I like it when projected costs drop by an order of magnitude.

Unfortunately, 130 watts isn't very much when it comes to standard appliances (http://www.flatheadelectric.com/energy/appliancewattage.htm). I'm sure you could run a modern little LCD TV from it, though. Or a laptop. Best to have it charging a battery that other things run off of, of course.

Hrm. The problem most people have with getting exercise is that they'll buy the equipment/membership and then not use it. What if you had a bike powering a small TV/DVD player, with some added DRM so it takes special DVDs that only play on it. Rent them out from a Netflix-type service. Now, the equipment purchase includes an ongoing reward you can only get by doing the exercise. I know I'm hooked enough on certain shows that I'd keep peddling for hours to finish the season...

Hmm. So you could run most of a computer or... oh, cool, an ice-cream maker! I wonder if that includes chilling it, or just turning it?, or a stereo, or most of a TV...

I think I'm with you on the bicycle-tv combo. Turn zombie time into productive exercise! Or maybe bicycle while surfing the web, though dripping sweat on the computer is probably a bad idea. The trick would be to wire the tv or computer so it *won't* run without a certain input wattage from the bicycle.

I'd sure be willing to pedal for an hour a day to watch Stargate, or the Tick.
