I works! I used lamp oil before I read that I should use alcohol but it still runs well.
Now I want to know how it works. I see that the hot side can have higher pressure than the cool side and push the cylinder to the right but what causes it to go the left? Also what is the design of the fitting between the glass tubes?
I am very satisfied!
