This is a single piston thermo-acoustic alpha(1) Stirling where 1 piston performs both fuctions of displacer and power piston.Compared to a low-temperature difference gamma(2) Stirling engine.
I was not clear on this point, THIS Stirling engine uses atmospheric pressure to boost its power, BUT if the piston were gas-tight, it would work in a vacuum.

Today I was running it on 99% isopropyl alcohol. I've found it carbon ups the tube much more than 99% ethanol (but it's a LOT cheaper!)

WARNING: Hot parts, open flame, flammable liquids. Danger of fire and burns. Not for children. This model vibrates badly and the fuel can gets way too hot. Use proper precaution. If you don't know, learn first or do not do it.
