Re: Usable Power for Stirling Engines?

There are a several reasons why you only see Strirling engines which are heated. First is that, for an engine capable of producing any substantial power, you need the temperature differential between the hot and cold end to be in hudreds of degrees F. So if the warm end is at, say 70 deg. F ambient ...

Hi Wayne, Welcome to the forum! A couple of simple formulae to keep in mind. 1) The displacer cylinder is ideally divided into 1/3 cool and 2/3 hot. The displacer itself should be about 2/3 the total length of this cylinder. Also the ratio between the displacement volumes of the two cylinders is 33...

This question had not so long ago been addressed in a different thread. If you scroll down the topic list to a thread from December 2007 entitled "Suggested Readings?" you will find a number of recommended books. Hope this helps, best of luck.

I'm very new to the hobby, but to me, it would seem that you'd want the displacer to be a thermal insulator. I'm in the process of designing a gamma type engine and I was planning of making the displacer from plastic (UHMW or similar) with only thin metal caps on either end. Am I correct in my think...

Using a striling engine to get off the grid

Hello, I'm a newbie to the stirling engine world in need of some basic advice. I only recently learned about stirling engines and it appears that this would be indeal engine to run a ~10kW generator. I would like to start off by building a small scale version of the engine that I will ultimately use...
