Does anyone know of a source for small steam turbines?  Anything from the
size of a dentist's drill on up to something that could generate several
horsepower when properly geared.

Also I am looking for a source of small generators which could be connected
to the various sizes of steam turbine mentioned above.

The purpose is a battery replacement system that runs off available heat
or steam power.  The small version would be intended to power low load 
devices or trickle charge batteries.  A large version might power a small
portable computer.

Any other type of commercially available heat engine (ie: a sterling 
engine) that might take the place of the steam turbine would also be
a possiblity.

I'm looking for stuff that is available out of stock and wouldn't requre
me to do any custom metalwork.  I just want to bolt the items together
and watch it spin.  Low cost is more important than efficiency, this is
just ment to be a demonstration experiment.
