Nichrome wire...good thought! I wonder how much current I would need?

Ian, I gather you are thinking along the lines of a Gamma-type Stirling with the electric heating pad. I'm thinking more along the lines of the two-cylinder Alpha-type Stirling and putting an electric (or some sort of non-combustion) heat source INSIDE the hot cylinder (presumably at the end). Diese...

Anyone know if plans or details exist for this one? I suspect the cylinder and cylinders are from some sort of off-the-shelf pipe, but not sure about that.

External combustion, more than just a phrase. :mrgreen: Indeed. :razz: Yeah, some sort of electric heating element might be worth a try. Now, I wonder...if the flywheel were set up to function as a Faraday wheel (ie. generate electric current from it's spinning), how much efficiency that might add ...

Cool...I took a look at airpot.com, but I don't see pricing listed...how expensive are the glass cylinder/graphite composite pistons just out of curiosity? So, I suppose I could disassemble and simply take the O-rings out. In your experience, would that remove enough friction but still leave the rig...

Thanks for the reply Ian. Overall, I can't see how putting the heat source inside the hot cylinder (if possible) wouldn't be beneficial. True? I'm trying to think out of the box on ways to do that.

Just curious here...has anyone ever tried using a spark plug or diesel glow plug mounted inside the hot cylinder as the heat source? It sure seems that you'd gain a lot of efficiency by having the heat source inside the hot cylinder versus outside the cylinder. (I'm not saying ignite any fuel inside...

Any updates? Did you get this working?

Cheers,

Hey folks, I'm new here...greetings! I'm curious if it would work well to use small pneumatic actuator cylinders for a small Stirling engine model. Has anyone done this? Pneumatic actuator cylinders can be had quite cheap, and it would avoid quite a bit of tedious construction. Here's a link (for ex...
