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: youtu.be And to learn all about fresnel lenses watch "Fresnel lens - what is it, testing focal lengh, solar heat generated": youtu.be For more, see: rimstar.org My cone solar cooker: rimstar.org and sun finder: rimstar.org Follow me on Twitter: twitter.com - rimstar.org
