Just as Ian S C says, it should run as long as there is heat. When you remove the heat, it's no problem that the flywheel spins a few rounds then, that's just good. It then runs on the heat that is left in the cylinder, and the flywheel slows down. Do you have other photo's of it? It looks like an i...

Hi, You could search on Youtube for 'popcan stirling engine' . That should give nice examples, and also build tutorials. CAD drawings you wouldn't find for it. You could look up our engine '2-Cylinder Gamma Engine - project' a little bit down the page, we also made computerdrawings for that engine. ...

Hi, basically ratio between the displacement of the displacer and power piston should be 1.5 : 1 You can choose wich one you set, and then adjust the other so the ratio is right. the height of the displacer (steelwool) should be as high as possible in the cylinder, if you say the cylinder is 8.5 cm ...

And the video is online!

The video shows the starting up of the engine, a great bit of constant speed running and a top speed (this time) of 420 rpm.

Hope you enjoy the video, and we'd like to hear what you think.

Really exciting news indeed.

Nice that you take the trouble to inform us, i would say: keep going!

Currently a 9:40 min. Video is uploading to YouTube...
It will take a long time, because it's a big file, and internet connection is slow, but it will come.

Stay tuned !

Thank you tomostre! It's running now! I knew that the displacer should drop under it's own weight, and it did. The engine did try to run, it eventually started at 280 rpm's, and gradually decreased till it stood still. The thing about leaking air was the problem. I tested with a little flame at the ...

I'm afraid it will take a little more time before the running-video will be online. wanted to make a nice video, beginning with startup from the engine. Last friday i had the camera set-up, and then the engine won't run. Have tried today(saturday), but the engine will not run. The last time the engi...

@ Ian S C, i agree with that theorie, but because i spent so much time on the crankshaft, i'm a bit cautious with it, but i will try harder, no doubt. First i glued it with loctite, that broke. Then it was welded, with a chance of burning the bearings. Then there were a few bad welds, that are now f...

@Ian, Ok, thank you for your answer! I will try to push the engine to higher speed, but i'm a bit anxious to destroy the crankshaft, but is will see. It is running very smooth, so i believe it's possible to go above the 600 rpm. mark. Also thank you for your help with the building, the tip about the...

Good News! Got it running last saturday, the first of March. Made bigger flywheels with a diameter of 30 cm's, instead of 12,5 cm's. The engine then first ran on the heat of the burners. Got a RPM of 270 then. The flywheels were at that moment 600 gms each. Total of 1.2 Kg. Made the flywheels lighte...

Hi Ian, thank you for your suggestions! The diaphragm is right, there is a bit slack remaining, i think that's good. The crankshaft is actually 6 mm, maybe it could be 8 mm, but when welded properly, it should do. It can spin freely with the parts disconnected. The flywheels are about 300 gms each, ...

Nice book, seems to me a very good book to read.
I'm afraid it is a bit too expensive for me onfortunately.

If anyone buys this book, i'd like to hear their opinion!

Greets,

wow, that is really impressive! I'm curious when they will deliver the first series of the generators. I don't want to be too distrustful, but there have been other companies that were to sell engines, and we never heard of these companies. Hope this company will survive. Nice to see that there are ...

have done a great lot after my last reply, trying to get the engine to work. Welded the cranshaft, and it broke again. Bad welds. Rewelded it (careful for the bearings) and this evening it broke again... We were testing with chafing dish alcohol burners. Sometimes the engine wil maken 2 or 3 revolut...
