When I was almost Kid studying physics, I imagine it was possible to compress some gas (maybe hydrogen) until it became liquid, and if the container could be super ultra strong, it would keep it cold forever if the container would keep holding, and be used as a refrigerator or so. I was imagining the heat would be converted to presure to the tank and then with time dissipated.

Would this be the spectrum in space or at the bottom of all the air and water?...and that problematic combination of the two clouds.
