Fresnel lens solar cooker using TV lens

Solar cooking using my fresnel lens solar cooker made using a 2'x4' fresnel lens from a rear projection TV. I show it cook minced pork, burn a leaf within seconds and how to find the focal length. See also my video "Fresnel lens and mirror solar cooker cast iron pan" to see how I use a mirror with this fresnel lens to put the bright light on the bottom of the pan so it's not in your eyes: http://youtu.be/hWDkCnpLRPA And to learn all about fresnel lenses watch "Fresnel lens - what is it, testing focal lengh, solar heat generated": http://youtu.be/11n0ZaZMj3A For more, see: http://rimstar.org/renewnrg/fresnel_lens_solar_cooker.htm My cone solar cooker: http://rimstar.org/renewnrg/cone_funnel_solar_cooker.htm and sun finder: http://rimstar.org/renewnrg/sun_finder.htm Follow me on Twitter: https://twitter.com/#!/RimStarz - http://rimstar.org
