Hey /sci/

I'm interested in building a Stirling engine. I went to Wikipedia and the first thing I saw was this really simple configuration pictured to the left. It seems like this would be really efficient, but that it might only work in a zero-gravity environment or something.

Anyway, is there a way to make such a simple configuration work here on Earth, or is it too simplified?

/sci/, when it doesn't know the answer to a question, it just calls everybody stupid.

What, is that like a StarCraft joke or something?

Ignore that unhelpful asshole. What you mean is weightless environment.

An astronaut aboard a shuttle in orbit isn't in even close to a zero G environment. He is just (apparently) weightless. Zero-G is a misnomer.

I know how to answer the fucking question, but if you are just learning about sterling engines, it means you are a little kid. And the fact that you think this only works in zero-g makes you a retarded faggot.
this will work just about anywhere. Go on jewtube and look up videos how to do it

Oh ok thanks.

I was wondering because the pistons are going at right angles to each other and it seems like gravity would cause one or both of them to grind against the cylinder wall, causing friction and less efficiency. But an astronaut might see one of these running without that sliding going on at all when he's in orbit.

If you're going to criticize someone for being curious like a kid, at least spell your words correctly...

OP here again, I just realized something

If you position it like in the picture with the hot side as the one position horizontally, then it will be the one with the friction... That friction produces waste heat, and... that waste heat just gets fed back into the Stirling cycle. No real problem then?
