How Small an Engine?

Postby stan.hornbaker » Fri Jul 18, 2003 2:33 pm

A mini-Wankel engine can be seen

Smaller than a quarter! It works and the set up operaion is shown.
It may be too delicate a job but why not a mini-Stirling? This would
be a real challenge for a watchmaker or a home machinist with
precision machines.
