  2. Hi,

    The part A we use is on our website greenpowerscience com and is listed under reflective material. Part A is a good choice. (worldwide shipping) To cut in strips do this:


    Thank you for enjoying our videos.

  3. i am having some dificulties on buying the reflective tape. i bougt an aluminium and another was silver but both are not reflecting not good. can you help me please? is there any special one in the market? From Portugal .. love your work. thanks

  4. im sorry for posting again but i had another question what if want a flow of water to pass through the trough with a pump and a tank what tube do i have to get??

  5. hi dan i wanna ask a question im buliding a trough and i want to know some things does the water in the evacuated vacum tube go in and out i mean is it open from both sides and how can i get the ?? please reply asap

  6. Hey Dan!!! great job you’re doing man … thanks from the kid in me! I had a question if you don’t mind. I was wanting to make as much steam as possible and thought of two things. 1) if I put 2 or 3 heating tubes in series together in one trough, do you presume it would produce more heated water? 2) if I made the heating tube out of a piece of rectangle tubing, off set the inlet/outlet to the top, half full of water, to get more steam less water? a little more surface area also? Maybe? Thank you

  7. I have a solar thermal system on my off grid solar house this looks like a new project for me 8)

  8. Vertical requires a heliostat tracking device. If you place it horizontal and East West you only need to adjust for seasonal sun positioning. The later is less efficient as you lose about 20-30% in the AM and PM.

  9. how often do you have to reposition the trough?

  11. About $25 dollars on ebay. Give or take. Its cheaper if you buy 10,000 of them..

  12. Hi Dan
    Another fantastic development! Seems you already did what it was I thought would be great to see. Now, what really interests me is the following question.
    If you were to fill the two dimensional area of the parabolic mirror (2ft wide) with as man vac tubes as would fit, which would give you the greater output? I thought of putting these in an array, but it might be better to use use vac tube? Have you dont any research on the output?

  13. The way to do it is to use oil in the tube and a 4ft steel pipe 3/8″ dia in the oil with water in the steel pipe. The thin glass does not support more than 15 PSI, so the oil acts as an exchange medium at zero pressure. The caps on the steel pipe need to be sanded to fit. Oil alone will reach 400F+ without a trough and well beyond the smoke point without a heat remover.

  14. Has anyone successfully used evacuated solar tubes to produce enough steam for a steam turbine? I’m interested in doing this as an undergrad project for college. Perhaps a battery of them side by side at the focal point of a large parabolic mirror which could track the sun. The steam would travel to a Tesla Turbine and then into a condenser to be reused. Any thoughts?

  15. They are from solar water heaters, They are about $20 each but almost impossible to safely ship. Smaller ones are much easier.

  16. Where can I get vactube this size and what is the cost?

    By killawat1000 on Apr 16, 2013

  17. how much do the evacuated tubes cost?

  18. :-)  Thank you for the nice comment.

  19. Dan!!! You are the man!!!!

  20. hey, i am very health conscious, i wonder, does the metalic film in the tube is sprayed on the very inside that touches the water or on outside of inner wall ( outside-glass-vaccum-film-glass-inside ) ?

  21. does this parabala mirror optimise focus of energy from certain angle? Will energy reach the tube if it is coming from other angles?

  22. Your work I like. If you can -look at my Chinese water shoes.
