Water and Energy

Water filters and purification tablets can be invaluable. For about the same amount of money you could build a small still from an old pressure cooker, a radiator and some fittings and tubing. I've just started working on combining this simple still with a solar oven.

By the way MCG, those are great links! The page on electronics looks especially useful to me, as I need to learn about it from the ground up, and have never found anyone to teach me. So thanks!
