Solar Hot Air
U sing parts easily available from the internet (see helpful links) and your local stores, you can make a small solar power generator for $250 to $300. Great for rolling blackouts, life outside the power grid, or the coming zombie apocalypse. Power your computer, modem, dvd, tv, cameras, lights, fans, or DC appliances anywhere you go. Use in cabins, boats, tents, archaeological digs, or while travelling throughout the third world. Have one in the office store room in case of power failures in your highrise.
