Pop can Stirling engine, 0-900 rpm in 3 seconds!

I've tightened the engine up a bit and quietened the noise down some, and it runs pretty fast. If you watch the time on the video you'll see it gets to full speed very rapidly, and takes more than a minute to come to a full stop after removing the heat source. The steel wool regenerator retains a lot of heat.

dude it sounds like a Chinese diesel motor

[approtechie]

@piffsterr2 Unfortunately the mic boost on my camera was turned up and amplified the noise. It's not actually all that noisy. Anyway, I sort of like the sound of those diesels. :)

can you send the plans to me on how to construct this stirling engine please :)

[approtechie]

@cymru1100 Man, I get all these requests for plans for this engine but it really didn't last all that well, the pop cans are pretty fragile and eventually collapse, so I've not produced any plans for it. Sorry. You can look at the 1065 rpm video I have up and at the end there are some photos of how I made it.

I just want to know what is in the somewhat large and square platform that the engine sits on.

[approtechie]

@TheOnlyCanadian25 It's an empty metal box with some small welding magnets on top to hold the engine steady while I videoed it. There's also a Sterno can on top with alcohol in it for heating the engine.

Quick! There's no top comments! Someone say something funny! Uh... This engine sounds like a fapper..?

[piffsterr2]

@approtechie darn, I have a 90's iseki tu220f and it sounded just like the pop can motor!

[megamaster1011]

[wheelmangrahamco]

[Robots4Sale]

Sell it to me
