That turned out very well.

I wasn't sure what it was going to look like, but it looks good, too.

I agree that these look best running at a slow to medium speed.

Thank you for posting,

With this engine, I think "moderate " running will be better, not necessarily running very fast, running slow it has its beauty because can see everything in motion...
Anyway, Thanks for the suggestion.

As I showed the drawing to insulate the heat inside along with a part of displaces the cylinder inside to avoid heat loss and run economically.

To regulate the speed of stirling engine, you can regulate the height of the flame with the regulating knop in the same way as you do with a kerosene lamp when you regulate brightness/darkness. You can use spirit/alcohol instead kerosene due less soot.

An Ky-Ko stirling fan are using 1 liter kerosene in 48 hours and the height of flame can be regulated as a kerosene lamp. :)

If I really want to make an efficient, economical engine.. I'll do it like the video below, and change it to a fan or something...add a few things like legs, alcohol lamp ...and honestly it's too easy for me, and sure performance , saving is very high, better , nicer... ,





But This topic is just what I wanted to present: "another way to make an engine"
If someone finds it interesting, they can build it, it's very simple, and of course they can do it better, better than me....good for them.

Hi All !
Story continues....
I just made a preliminary design
I will use iron pipe with ID 25mm and I think when finished it will probably have ID of 27mm
First how to cut gears , maybe I'll make a gear cutter using a 12 volt motor
A long term project....

My Father used a scrap brake cylinder to make a steam cylinder for an engine. Not sure iron pipe will machine to the right grain as a proper bit of cast iron.... material temper condition is all important to get good grey iron.

That's also a way
Thanks !

I have used all the available as well as purchased: aluminum, brass, steel, cast iron , Stainless Steel..
And including the welded steel tube which is 2.3mm thick and when finished it's only 1mm thick and I use it in several internal combustion engines, flame eater, they're pretty good.,

Hi Doug !
Thank you !

A behind story : I had instructed some students in Viet Nam to do a topic at school on stirling engines , then they sent me pictures and videos - engines are so ....bad , and I said to them : " why not make it more beautiful . .." The answer I got was: " me , we don't have the machines to do it "
This is also my answer to them
