Gunner,

In my followup article in , I wrote about "common sizes or patterns" for steam and Stirling engines, vis-a-vis small gasoline engines:

Here's a separate nudge to underscore the above sentiments and hint that if you types want to preserve home industry, the above is one direction in which you might try to help develop a market. I'm eager to work with anyone in evolving a low capacity Stirling genset.

I thought the British had a small Sterling genset they used for quiet powere in combat. Probably expensive as hell, but would be a good starting point for re-design to cheaper non -mil-spec.

There is one that is trying to break into the yacht market. Called a "Whispergen". It is a 4 cylinder Sterling that produces up to 800W at

12V and 18,000 BTU of heat > Date: Wed, 15 Oct 2003 00:05:26 -0700 (PDT)

I have a somewhat long-term project to build a 1 KW solar-powered generator. It seems to make Stirling engines efficient, you need to run them on pressurized gas, either hydrogen or helium. The higher gas density makes the engine VASTLY smaller! Using a simulation program that was published in a book, and takes into account most losses such as heat transfer and gas fluid friction, I can get

2 shaft Hp from a 50 cc displacement engine running around 3000 RPM. This is with Hydrogen at 800 PSI as the working fluid, and the heat absorber running at ~ 700 C, and the cold side water cooled at 75 C.

Mostly, I need to get an AC TIG machine first, to weld a zillion heat exchanger tubes.
