Modern Stirling Engines

I recently had a chance to visit a company called Stirling Technology Inc. in Athens, Ohio. The founder of the company has been engineering modern stirling engines since the 1970s and helped design a 5 hp hot air engine to run on rice hulls intended for developing countries (see cutaway machine in the photo below). The company is now producing a home generating unit for supplemental power and heating, i.e., the excess heat from the engine is used for space heating or water heating. The unit mounts on the wall and is about half the size of a dishwasher (photos below). It can use multiple fuels and the company has recently developed a unique gassifing burner for wood pellets.

Were they kind enough to give you any information on how to go about buying one?

It burns my britches when you click on "purchasing" and get "nothing found" :rant::rant::rant:

But it doesn't surprise me at all...

Yes, just contact them for a quote at:

Depends in part on what kind of fuel you want to burn like wood pellets, propane, britches, etc. They are just beginning commercial production of the ThermoGen CHP units which is probably why there's no purchase link yet.

Yes, they use a free piston design (no linkages) which was first developed by the late William Beale and the engineers who worked for him, although I'm sure there have been many improvements since then.

This one looks like it's might be there early design puts out some power

That's one of the ST-5s from the 1970s--same as I mentioned above and same as in the cutaway (2nd photo above). It was rated at 5 hp but could not achieve that with the primitive burner setup shown in the video.
