The water supply to your home is something you probably never think about until there is a problem. Heck, that's a way of life for most of us. Out of sight, out of mind. But with domestic water treatment plants, and even well water subject to breakdown, what can be your backup? The sun, that's what!
If you have access to the sun (heh) and a water source (almost any
water source, clean or dirty), you too could be the proud owner of a clean water plant in that backyard sometime soon. That is, if you're up to building a miniature water distillation plant
powered by the sun's rays. Yep -- no power source is needed here except the sun.
This has to be the coolest home gadget
I've seen in a while, although it would probably not be used except in an emergency, or with someone wanting to provide clean water without any outside sources except maybe a nearby stream and sun access. Are you into mirrors, parabolic arrays, mylar, and some wire? Yes, this project takes more than that (plus some serious elbow grease), but the next time a tornado comes to town (or a hurricane), this project could be a lifesaver, literally.
