I've never built one, but researched a lot. I guess you're going for an alpha style. Those are 1:1 I think. There are some guys on YouTube that built nice ones. Chris workshop for example. You'll probably find all the info you need there. This forum is slowly degrading as there's no moderator anymor...

Swept volume you mean? The bigger the displacer is compared to the piston, the lower your temperature delta can be. It goes from 1:1 up to however much you want. In theory.

I'm using my own frame of reference here and I hope you can explain your theory in that same reference. I'm working around a "de Laval" nozzle. Basically flow is chocked and reaches mach 1 only for then to be expanded and reaching higher speeds. How would your theory explain that sudden ri...

Well I guess the electron cloud could be seen as a beach ball.

I still don't see what you, Tom, think heat itself is then, in your theory.
How does the beach ball get larger? What does heat do to it to make it larger?

I believe the work will come from the kinetic energy of the gas at elevated temperature. Normally the kinetic energy is wasted, as pressure only increases linear to temperature, while molecular energy does not, as evident by the emission of visible light above a certain temperature, and phase chang...

I'm ok to chip in with some moderating, but I don't have the time or will power to maintain a whole forum.
I've enjoyed this place and it's sad that it's leaving. A replacement would certainly be nice.

But what is heat in your theory then? As I understand it, you propose that the fluid molecules are little magnetic balls basically. Then what does heat do to increase that magnetic field? And how is it taken out by converting it to work in a stirling engine where the hotter molecules don't "tra...

What would that entail exactly?

Thanks!

I think they're misunderstood. But I have no first hand experience with them yet.
So first I'm going to be trying a lot of things.

These turbines actually work better the larger they get. So you could be right about that.

Hey guys, long time no see. I've been busy with some stuff around the house and the first parts that are coming in. I need to reorganize a bit so I have more work space for all this. signal-2024-09-09-11-40-13-075.jpg signal-2024-09-11-12-52-55-602.jpg These and many other parts have come in and mak...

My intention was simply to build a Stirling engine to run on my wood stove. Something with useable power output, which seemed to suggest that improvements in Stirling engine design would be needed. I've seen that reason mentioned by many guys on this path. It's my own reason for being here as well....

My idea was to insulate the entire engine with a controlled way of adding heat. And then measure the work output and cold plate temperature. I'm not sure in what way you would set all that up and that is not anything I have done so.... Not really recreating "Tom's experiment".at all. Fair...

As per title, I'm curious and have some time available. (...) I have easy access to this Stirling engine from a local ebay variant. Screenshot_20240722_170123_Lazada.jpg Would this be sufficient? Not to be critical of your apparent interest but "Tom's experiment" is too vague, considering...
