Published on Sep 25, 2012I'm considering this. There's potential danger in it, though. These lenses are powerful and can be dangerous.
First attempt to cook with a dutch oven and a fresnel lens. Worked okay, took three hours to make. Good for small container cooking, don't know if it will work on larger kettles. Fresnel lens and Dutch oven purchased thru A Plus Survival in Santa Ana. At the end of cooking when I was putting it in the bowl the front leg gave out and it all went on the ground, the second one I cooked the day after this was chicken and dumplings. That was great...
Update:
Greenpowerscience sells Fresnel lenses. The link to the left calculates out to 777 watts solar thermal power potential.
