The Small Piston Heat Engine features a piston with one-quarter
the surface area of the original Heat Engine (TD-8572). It includes
the same high-quality Pyrex cylinder and low-friction graphite
piston. In addition, the Quick Connect ports allow the two heat
engines to be used with one another or with the same set of
accessories.
Pascal’s Principal is demonstrated by
connecting two pistons of different diameters.
More weight is required on the bigger piston
to balance the weight on the smaller piston.

The Thermobile is a Nitinol wire (memory wire) loop around two
wheels. Nitinol (nickel-titanium) wire is called memory wire because
it returns to its original shape when heated. In this case, the wire
has been programmed by holding it in a straight line while heating it
to a high temperature. After cooling, the straight wire was wrapped
around the two pulleys.
When the brass wheel is immersed in hot water, the wheels will
begin to turn. When the brass wheel heats up, the wire in contact
with it is heated, and tries to straighten out. When the wheel is
spinning, the wire on one side of the wheel is hotter and bows out
more than the other end. This results in an unbalanced torque on the
wheel, causing it to turn.
