Com: GwHunter :What's the fan and the shroud for?

It's not blowing air on anything except for maybe a little on the generator that you enclosed in a metal oven.

Looks cool though; nice work!..

Com: indigo dragon : Challenge design a cold gas stirling engine that has a single helium sealed cylinder that ,

produces liquid atmosphere in a closed system that circulates that liquid atmosphere through all the piston cylinder heads and keeps it liquid.

With a electric motor start up to get the whole engine running.

Use gadolinium has magnetic cushions on wabble plate to drive cold air with a fan being turned by the magnetic wobble plate.

If you perfect it you should have a cooling unit you start up with an electric motor then the electric ,

motor shuts off and the stirling cold gas engine operates itself has it cools the air.

In the configuration like shown in the video.

A larger V-6 model could be designed that could provide both air conditioning and electrical power generation
