What if you injected a few water drops worth of mist into the heat chamber through a valve tapped in through side of chamber? Flash steam, assuming that torch is on the chamber?
@mangyscavenger A steam engine directs steam into and out of the engine, but a Stirling has no such mechanism. There has been research on phase-change working fluids for Stirlings but I don't believe there have been any successful versions yet. When a working fluid changes phase then it absorbs or gives off enormous amounts of energy (like liquid water and steam) but it's a slow cycle.
@akinorhan5 And more dangerous. The reason Rev. Robert Stirling invented this engine is because people were being killed by boiler explosions and burned by escaping steam from the steam engines of the day. The Stirling is inherently safer (especially if you don't use pressurized hydrogen as the heat transfer fluid). Hot air for me.
@approtechie ye i know ive seen a video from explosion of a steam engine i will make a stirling engine steam is very dangerous as you say its 100 degrees celcius + hot water i dont want to die :D
@AlexFaulkner2294 They haven't been available for years now so far as I know. The SunRunner was the engine that followed this and you might still find some for sale on Ebay or privately.
Dang, that's a nice unit. If there's some way you could get that little knock out of it, it'll probably last longer. That will hammer itself apart eventually.
What if you could hook a little fan up to the engine and have it blow off the cold side of the displacer? If you could get one just the right size — small enough not to drag it down more than it helps it — that would be 'cool' (no pun intended).
I don't really run it much since it has no bearings, only bushings, and they do wear out. Take a look at my other video of it called Stirling fan and you'll see this engine driving a fan and putting out a good breeze. Thanks for the comment!
Mike - thanks! I've looked at all of your own engines and am frankly amazed at the variety and the nice workmanship. Very nice presentations as well. - Cliff
Cliff, thanks for the nice compliment but it rightly goes to Jos de Vink (YouTube ID mdevink) who is the great builder of stirling engines. I have a very similar name, and similar interest, but haven't completed building anything so interesting just yet. Cheers - Mike.
Do you have any DIY plans for this?Can you pm me? Many thanx.

@halfmumi No, this was a commercially-produced engine made by Solar Engines of Arizona. PM Research apparently still markets a version of it.

The Sunrunner version of this engine is apparently still available from PM Research but the price is a lot higher than when I got mine in 1980.

google pm research inc - under solar engines you will find the sunrunner

No boiler full of hot water necessary.

YOU SHOULD MAKE A STEAM ENGINE ITS POWERFULLER
