When I get my next paycheck, I’m going to buy one of these, from this website.
It’s a solar powered LCD flashlight. When you buy one from their site, an additional one is sent to be distributed in the developing world, to locations where there is no electrical power. I think I know what my family is getting for gifts for a while. Now that I think of it, I may get a second one for myself to use as a battery charger for my camera batteries.
