My Stirling Engine from Kontax

[JayTee441]

Here's the problem with the engine I see in the video: the top is either glass or more likely plexi- so heat transfer is very slow. Make the top and bottom from aluminum and the engine will start instantly and run much, much stronger.

This housing is plexiglass.

Kontax does make other models that use aluminum.

Aluminum is also not good as an insulator.

So, it would also lose the heat in the chamber fast.

The stirling engine works on differences between hot and cold.

So, it's an interesting concept to test.

Which material gives greater efficiency?

@RodgersResearch

Hi, you want the best conductor possible, to let heat into the displacer cylinder, and to let it out as fast as possible on the cold side. No question about it.

I've been trying for like as long as i can remember and i just recently got one working! It only worked twice tho and it really sucked just barely ran, but good enough for me lol.

awesome, I'm thinking about getting one soon, I've tried to build like 5 stirling engines from scratch and I can never get them to work so I'm just going to buy one lol.

@YupHio Keep trying. It took me over 20 times. I kept on lining up all the failure engines--Finally I started screaming when I got it working. :0
