A simple stainless steel parabolic trough mirror that produces a near perfect Linear Beam. This mirror was combined with a 30 oz vacuum tube and raised 70f water to 212f in 14 minutes.

we wanna see how to actually make one. not just some temp thing that wont hold up. anyone agree? show us the real way.

@steadfast1984 did that last year

How does that "tube" on it's own boil water?

[GREENPOWERSCIENCE]

@judoyodan it is a dark inner surface with a vacuum around it. Vacuums do not transfer heat well, they are a vary good insulator. Sunlight penetrates the clear outer glass and heats the black coating delivering heat to the water. Heat can only escape through the top. This builds temperature fast. This is a typical glass thermos but clear on the outside vs silver.

Dan! Awesome videos on vacuum tubes and parabolic concentrators... but we will always get stuck on the solar tracking for those parabolic mirrors.. do you have any DIY videos on solar tracking? I ask because the parabolas will only work efficiently during some hours, on those examples you made.. or not? are they effective when they're in a fixed position?

[hobbyguy]

ok.. where was Denise in this one??

[theboatsucks]

well if your temps, time, and water weight are correct you got 1141 btu/hr or 334.2 watts out of one small tube not bad at all. Curious about the total capture area for a guess on efficiency.

Wouldn't it be cheaper to line a cheap and bendable 1/8" plywood sheet with Mylar? That stuff is like 12 bucks for a 4' by 25' roll.....

@MTHKITEBOARDS There is a link in the info section :)

[MTHKITEBOARDS]

Where do you get that stuff "Mirror" I found it online but its like 300 bucks for stainless steel mirror 60 inch by 24'' 22 gauge

I just need something like in the video

Thanks

[impazzitoinvolo]

SImple and efficient! COngratulations!

Why not take the reflective film that Dan sells on ebay and apply it to some shiny black mylar veneer or similar black flexible surface, use it the same way as in this video. That would save buying stainless steel and would be easier than making the parabolic dish

@steadfast1984 Yeah, I have seen Dan burn so many pieces of of wood and cook lots of eggs and popcorn, I have never seen any practical application for anything he has done, he states the obvious constantly but you would think his house would now be heated, his electricity self sufficient and all his hot water free, yet we see none of this we just see a yard scattered with bits and pieces of science that most of us are aware exists and are looking to see it in a practical situation.

I see your videos are in an area I'm working in. I made

contact with you because I'd like to give you some money

for placing my link in your video description.

Call me to discuss it if you are interested 949-945-5417.
