You should check out cooking with Fresnel Lenses.

That’s severe radiation Boys and girls....can you say “Severe radiation”?....Good!

Pretty efficient and the old satellite dish is a great base because it has an easy to locate focal point. I’d like to see one made out of one of those old satellite dishes...on about 4 feet in diameter....that could be a lot of fun....

Elsewhere, I’ve seen how such an intense, point heat can be turned into something more practical.

Essentially a very insulated box, with a substance like sheet aerogel as the insulator, but inside is material that holds heat very well, having a high “heat capacity”. Then a conductive rod in the box has a metal ball target for the high temperature solar oven outside the box.

Alternatively, a much easier way to do this is by taking a Fresnel lens from a wide screen TV.

How is this any different or stronger than any mirrored dish of that size? Having mirrored tiles as opposed to a uniform mirrored sheet wouldn’t increase its power.

“Death Ray” indeed.

Rob Cockerham over at www.cockeyed.com made his out of an twelve foot satellite dish. He calls it the Light Sharpener.

Before sealed beam headlights cars used parabolic reflectors. We used to play with them, they will concentrate a lot of heat.
