This reminds me of a thermoacoustic engine. The simplest and earliest examples of such engines were the Rijke tube and the Sondhauss tube.
This was an awesome explanation man, really great stuff.
Let's build an open source version

Dope channel man! :d
Good explanation. It's just refrigerator cycle.2.0. Universiti should teach this instead of STHE and Double Piro HeX.
great video, subbed
Does the system need, say, liquid nitrogen cooling on the hot end of the pulse tube? I don't get how the temperature could be dropped otherwise with the compressor constantly putting work into the system.
The temperature drops first because it's reduced to ambient because of conduction through the heat exchanger fins. Then when the compressor reverses and expands the gas, it cools it. They key to this is that all of the heat generated by the compression is taken away by the heat exchanger fins. When the gas then expands and cools it's able to pull heat from it's surroundings.
@@operationalfacts5602 I see, so all it needs is the cooling on the heat exchanger at the compressor side, and only to ambient temperature. Probably also help to cool the hot end of the pulse tube, I imagine.
Bravo.....hey do u have one.......cheers
You should check out thermoacoustics to understand how a UFO 🛸 cools its engine and drives.
