The whole method looks dangerous to me!
Wasn’t that smoke coming off the cook surface when you re-directed the light source? Would seem that you’d better not let your arm or hands get under that sunbeam… yowser!
Give me a good old “dutch oven” over hot coals any day. (It’s what the American pioneers used.)

I bet it was. I wasnt in the boy scouts although I roll my t-shirts boy scout style only to save space and it looks neater. It’s so fun cooking with the sun, especially if you dont need to pay to use it. (E.g. gas or electric).

I just saw your video: “INSTANTANEOUS SOLAR WATER HEATER HOT WATER ” with the 35″ parabolic mirror. I would like plans for this where can I get them?
Also what about parts? Can an 8″ mirror be used?
thanks

Good idea and video. It would be nice to see a mirror reflect the lightbeam onto the bottom of the pan also. I guess it might be better cooking if it works, but slightly more dangerous to the user, so I guess some safter measure would havea to be thought up.

Forgive me about the misspelling of cooking in the last comment. I know what caused this, I had been watching “The Swedish Chef” on the Muppets…

Hey “demofish” and “airguitarfooker” – Those are both GREAT modfications to this project. A Venetian Blind arrangement on the Fresnel lense is a simple “Off-The-Shelf” solution for temperature control. The “Morror Reflector” is also good as the heat is applied to the bottom of the pan and you are now coooking in a conventional fashion only “GREEN” . Also the mirror will not break or melt reflecting the sunlight.

@coondogtheman1234 – I know what you mean, when I was a kid in Boy Scouts we did this at almost every campout. It was a real treat!

1:25 probably the same power that kills all those guys doing deep sea drilling for oil!

@Airguitarfooker probably would break the mirror

you could install adjustable shades over tne lens to regulate the intensity

You guys are well prepared for peak oil…great job…

Thanks for the safety tip

all that’s needed is powdered sugar and cinnamon. I like this.

Why dont reflect the sunlight to a mirror or something UNDER the frying-pan…that shoots up the heat to something that are keeping the heat good, making it like a “hot owen plate”…? Sry for bad english, im retarded…

Gosh Darn it Dan, I have told you before (the time when you were drilling holes) don’t be so hard on those cast iron pans

well yeah, you can throw water onto a skillet of any kind of frying-hot oil, and that would happen.

I enjoyed the video and i enjoyed Denise as the host. I know you are married Denise but perhaps you have a sister who is single?
