Closed chamber Stirling engine generator.

@tinu,

Thank you for your help. The red one is a displacer. The blue one is a piston.

I do not think I will get a phase difference of about 90 degrees between piston and displacer,
but I will get "some" phase difference because of the distance the blue piston will travel plus the distance
the springs will compress. The question is if this is possible to engineer so that the phase difference will
be close to 90 degrees?

Here is something interesting that I?d like to buy in the near future: Stirling engine used as fan (about 0.5W). A small standardized stirling engine to play with. 
Look for MSI PowerlessAirCooler, if interested.

Cheers,

@tinu,

If we redesign a PC in such a manner that we put every heat generating component onto the same plane and in a small
area, then we could have used MEMS-TAR systems to recycle 1/2 the heat back into electricity again.

A very neat and cool CPU cooler indeed.

@tinu,

Do you think this rotary Stirling engine will work?

Engine has a fixed position rotor and a sliding piston in the rotor. The piston will run flush at the cylinder walls. The heat is applied at the top of the engine and the cold side is at the bottom of the engine. Engine is a closed gas cycle, no venting to the outside of the engine.

Now that?s a brilliant idea!
I?d go for it as of tomorrow but I never put my hands on a wankel in my whole life, so it would probably be far beyond my actual technical capabilities.
One totally minor suggestion that I hope will not cast the slightest shadow on your ingenuity: place hot and cold on diagonal. Correct angle is to be determined as a function of elliptic and gas pressure inside chambers. Mere details! Exciting idea!!! I?m speechless?

Many thanks,
Tinu
