But it's pretty damn awesome.

And I'm sure that with the insane collective knowledge of Oppo Somebody out there will be able to explain it to me.

From the YouTube comments: "This is a video of the flame gulper engine pictured on the "Models" page of my Engineman website. The fuel is alcohol. It was made from plans in the February 1950 issue of Popular Science. Modifications were made to replace the castings originally specified, as I doubt they were available forty-odd years later. My model has run a lot - whenever visitors drop by and at a few exhibitions."

Looks like a stirling engine.

A picture is worth a thousand words. A gif, about a thousand and ten.

the flame goes into the expansion chamber and the breach closes.

hot gas cools and contracts and pulls the piston closed.

breach opens, cold gas escapes, hot gas goes in. repeat.

Friction welding is bad ass.

Don't know if it's exactly the same but both concepts are very cool.
