i want to make a stirling engine sobad!

@CPD0123a You can take a look at my newer engine, same size, same cylinder, but beta configuration with the diaphragm over the cylinder - drives a 20" fan at 800 rpm on propane, leaves this one in the dust.
-
@CPD0123a I've often pondered a multi-cylinder engine. The heat can be carried away by a chimney so the space doesn't get heated if that's an issue.

@approtechie wait, so not only is it powering a fan, it's also powerful enough to pump water to cool itself?!?!?!?!? HOLLY CRAP! I wonder how much a 2 or 4 cylender version could do... Hmmm...
Kinda self-defeating though-heating the air to power a fan that cools the air... Lol, who cares!

Will to post the plans? I have group of youngsters to keep busy!
Very nice job, I am amazed at the power.

Can that be an electric fan?

@BENJBIDA I'm sorry but I don't understand your question. The fan blade is from an electric box fan but it's being driven by my engine since it's connected directly to the crankshaft. The whole idea here is that you don't need electricity to have a functioning fan or whatever, you just need a heat source.

i really hope you reply to this. I'm wondering if you can run the hose from the bucket to a radiator in front of the fan and make an air-conditioning. also if its not possible to have a chimney or just inconvenient you could have a pipe go any direction you want and just hook up a sterling engine to run a fan(though that may not work just an idea).

@virtualnoodles You certainly could run the hose to a radiator and us the fan for cooling the water/heating the air. A chimney would help to get the heat away from the area you're trying to cool with the fan. Or as you suggest, a Stirling fan could be powered off a stove and be used to force the smoke/gases out, but getting it started and having reliability and safety might be an issue.
