Building a homemade stirling engine.?
As a school project I need to build a stirling engine out of household parts (just no kits) that will be powered by a household iron. The main criteria is efficiency as this is what a large portion of the mark will be based on.
Firstly what configuration is more efficient, simplistic (Alpha, beta, gamma)?
Would anyone know any good links for plans or instructions where I could get some good initial ideas?
Any other tips of construction, materials, etc.?
Thanks for any help.
