Stirling Engine

Matt, Teresa and I built a full-scale Stirling engine for use as a power source for a future mechanical computer. Stirling engines are external combustion engines. This one will derive its power from pressure differences created by the exchange of heat between hot and cold water compartments.

We’re a bit concerned that the crankshaft may not be straight enough to maintain balance for the flywheels. Actually this is part of an overriding concern about how much power the engine will provide. We’re pretty sure it will be able to spin itself, but not clear on how much torque will be generated. It’s essential that the engine generate excess energy so that it can be connected to the mechanics of our yet-to-be-designed computing system.
