  1. They are very handy and you can carry one in your wallet

  2. Large Fresnel lenses are free in any rear projection TV. Every RPTV has one the size of the screen. Do a you tube search. Not terribly portable, but quite handy for cooking without power. Be careful!! Treat it like a cutting torch. I hear the ones from older RPTVs work best

    Do a YT search for solar ovens/cookers and rocket stoves. Lots of ideas out there.
