first time use for parabolic cooker

Hi I'm Ronald and I took apart my flash light and took the reflector out, and to my shock it melted my cup as well made boiling water. Since then I bought an 18 inch parabolic dish from and cooked spam in it. Still trying to find the right spot and focal point instead of using my hand to feel the hot spot.
I now use it to catch rain and guide it in a big cup where its clean and quick to collect rather then a cup itself.


Greetings Ronald,

Thank you for sharing your solar parabolic and cooking experiences.
Yes, you can use the tiny parabolic from a flashlight to generate a bit of solar heat.
I heard from a gentleman who used his car headlight parabola to do the same; and that got him hooked onto solar cooking. He now uses a commercial solar parabolic to cook at temperatures of 850 F. You would not want to use your hand though to find that hot spot.

Thank you for sharing with us and if you have any other "solar discoveries", Please do share them with us.

how to catch rain drops for drinking
by: ronald

i have a photo of a parabolic dish for survival. get a tall container and with a large dish put it on top of the container to be filled with rain water. all water drops will surround the solar cooker and flow constantly through the little hole really fast. or if you have a small cup you can use the parabolic dish from the flashlight just remove the bulb and use that as a rain catcher. if none of these available use a funnel which can be used as solar and a concentrator for rain drops as above. try it it works.
