My students pulled this off this afternoon...I thought you guys might find it interesting.

Crazy, but I could hear the comment, "needs an indicator on the fly wheel". Anyway, would a Stirling run in hot water? I challenge the students to pull that off next.

By Indicator I think they meant a sticker or something so it would be easier to see the flywheel rotating.

They got the PSI down to about 20psi under water!

Then they wanted to go out and put goldfish in the tank!

As cool as that sounds...I had to say no.

Stirling engine under water......that would be a trick.
