Russell,

Do you have any pointers to real Stirling designs? Almost everything I have
seen is a toy, or an ad. The one real engine that I saw, using a Briggs and
Stratton mower engine, only had pictures. There were no design specs or
power output descriptions.

The theory makes sense: have a hot and cold side. Heat fluid to the hot side
pushing a power piston. The displacer moves the hot air to the cold side
pulling the piston back in.

What I need to some design that I can point concentrated sunlight to and
get some results. I can finally see that using a car turbocharger and
intercooler. The only missing number is the turbine inlet pressure.

Ideas?
