Sounds like the basics of a Sterling engine.
I saw one on the internet that ran a small
Piston "engine" from the heat of your
hand holding the copper bottom which also served
as the heat chamber. (URL=?)

Hi folks,
My first attempt to post to the list, here. Ever heard of a heat pipe, a
tube with liquid in the bottom and a gas above it? The liquid boils above
room temperature. When the liquid turns to gas at the bottom, it bubbles up
to the other end, cools, condensed, and falls back to the bottom. An example
of this effect can be see in those Christmas tree lights with a tube above
them that bubbles.
I was wondering about applying this to locomotion. A piston might be pushed
due to heating a phase change of a liquid/gas in a chamber under the piston.
Cooling to room temperature would cause it to contract again. Anyone heard
of such an idea before?
