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.
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.
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!
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.
