Thank you everyone for you suggestions, I've tried a few things but not working. So am keeping my eyes out for an old jack I can repurpose. I did try a water piston so made a fluidyne engine which was surprisingly easy. So the project has moved on slightly and now playing around with different coils...

Hi Everyone, I've have sourced some steel tubing with an inner diameter of 33mm. I'm having trouble thinking of what use as a piston. The biggest problem I have (so far) is I don't have a lathe. I'm a little lost on what to do. End point I'm going for (I know thus may not work) is a much larger vers...

High pressure air power is the future. No need for unnatural lethal AC power at all. Anything in a homestead with a motor can run of airline or tank. No need for conversions and expensive electronic. 800 watt motor almost perfect match for 1kw free piston engine https://www.youtube.com/watch?v=AeSN...

I was thinking of using acetone, low boiling point and should make the sterling engine work more efficiently? As is heavier then air, but not sure if work make it sluggish or not.
Kind regards

Thank you guys.

I'll have a think and will let you know if successful.
So many different thoughts of what to try.... I hope this is normal behaviour lol.

Take care

It's all taking shape
Good luck with it.

Producing electricity via a sterling engine is something I'm very interested in. I was wondering if the sterling engine could be simplified by using the syringe model sterling or Heat engine and scaling it up using metal parts. Would this even work? If it did then a linear generator could be used. Y...

Sounds like a great project.
You based in USA or UK?
What size engine (Wattage output) are you thinking of?
Good luck with your project.
Kind regards
