Cool Mike, you're building a Sterling engine of sorts.  Also look into
the phase change expansion from liquid to gas, this requires lower
pressures but heat differentials that are not as extreme if the system
is kept on the edge of the liquid to gas phase.  Sort of a low
temperature steam engine...  It's not just the pressure change but how
quickly the change happens.
