I love the aesthetic of those alcohol burner powered Stirling engines but dislike the noise and the fact that they require an open flame. I’d prefer a version that was slower and used a different heat source (maybe USB power and a heating coil).
At home i have a kit to build a Stirling engine, need to see where i stashed it. I had one previously but i accidentally dropped it :c I do highly recommend the ones you can get from here though:

I have the KS90 model in black
Edit: Also if i recall that same site was working on making a desktop USB heater for the KS90 models. Similar to those mug warmers people buy.
Double edit: wahey, they made one. I’ll need to get one for mine
