Hi Dan- Rather than trying to transfer a known parabola from a dish to make a duplicate, look up parabola in Wikipedia, you will find some illustrations showing you exactly how to draw a parabola with any focal length you choose. Much easier and quicker than trying to match a dish that may not be the focal length you want. You can also reduce the weight by using just half the number of pegs if you use bender board on the pegs first, as a backer, then the acrylic goes on. Even stronger.

Check our website, I have an excel doc that works really good.

Question if you can, whats more reflective, aluminum, mylar or a parabolic mirror?

[GREENPOWERSCIENCE]

@blckjade05 Mirror, Reflective Adhesive, Aluminum Polished, Mylar, Foil, Spray paint.

IN THAT ORDER>

I wonder if I could cast iron with the Fresnel lens?

[GREENPOWERSCIENCE]

You can cast hybrid. Electric and solar. Basically use 75% less fuel. The sun alone can do small amounts with a large Spot Lens.

The problem with large amounts of metal, heat sink.

Hybrid works great

i love your videos dan, but personally would have just built it like a skateboarding haflpipe, with a parabolic curve....2 end pieces with horizontal beams..seems like a lot less work/weight

[IdahoViewing]

If you want accurate lengths then use a small block and clamp to establish the length rather than a marked line. You will be assured an EXACT duplicate each time.

Hi Dan, can you, or anyone, tell what is a cheap yet good black coating on sufaces to collect sunlight with that is also reasonably durable?

@RB13240 LOL...I spend all this time tryin to get ya all riled up and it just aint working. Darn Pantie wearing  Aerospace Engineers.....

:)

[MrSirPhase3]

@RB13240 Hey Aerospace engineer, I like the pretentious attitude. Don't get yer panties in a bunch.

[MrSirPhase3]

@athlon866 Obviously you have a much better solution, So, Don't just tell him what he did wrong........Get out yer video camera and show us yer quadratic function and draw a graph...............You've made er Sound easy, so show us how........
