  2. How much energy you can get of this thing? Nice work is real? Why I can’t
    see serious project with this technology? Can you give information about a
    big project with this technology.

  3. Nice Job! One limitation is that air is a fairly good insulator. I suspect
    that if you used a cheap can a lithium axle grease on the inside of the
    evacuated tube, it would hold up under the temperatures and would conduct
    the heat much faster than air to your stirling engine. Second thing, your
    radiator to expel waste heat shouldn’t be black and sitting in the sun.
    Keep as much sun off it as you can to try to get more power.

  4. question – i am a female with no mechanical or electonic experience but
    have been educating myself with the idea of passive solar heating from my
    condo window, but than discovered the solar tubes. I saw your video and
    said that is it! that is what I need to power the heat.
    Now………….here is the question – what do i need to do what you did?
    the tube, which I found on ebay, the stirling engine? But alot of them
    say low temp. Do I need a high temp? When you put the tube on the
    engine, did it cause alot of heat? I dont want to start a fire,but I want
    to create heat in my house……………. I would really appreciate
    input. I think the passive solar window idea will look like hell. this I
    could put in my window. I would be willing to hire you to make it for
    me……………. let me know. thanks.

  10. Hoe Simpel kan het zijn. Een leuke demonstratie van Roger Jonker hoe je met
    een zelfbouw oplossing van o.a. rest materialen en een demo Vacuum tube een
    sterling motortje stroom kunt laten produceren. 100% Duurzaam!

  11. Haha, Well done!

  12. You should spray foam around the opening or some type of insulator for more

  27. hi, so in summary is like a steam generator?… and honestly, a quality
    solar panel vs this evacuated tubes, which one generates more energy???
    (per square meter)

  28. I have been researching this a lot lately.
    For northern climates these tubes are more efficient because you get year
    around use. Southern climates go with flat panel.
    And also always plumb your flat panels so the fluid fills from the bottom
    to the top.
    Not top down as said in this video.
    See Dr. Ben Gravely.
