Fresnel Lens Solar Cooker from a FREE TV on Craigslist - Total cost $3

Look on Craigslist under “free stuff“ for a old style rear projection TV, there tons it does not have to work but the screen has to be intact the bigger the better. Garage sales are a good sources of other building materials. PLEASE WEAR A WELDERS MASK/DARK SUNGLASSES FOR YOUR OWN PROTECTION and DO NOT look direct into the beam with or without glasses it WILL damage your eyes :)
