I don't know if this guy is smart or foolhardy but I wouldn't try it.

    Love it… watching from far off. So ya say, all this saves 2/3's the cost? Hmmm. You gotta need a lot to make that worth it. Dangerous mad scientist play has it's value.

    Maybe it won't liquify air but souping up an old ice cream store appliance can achieve pretty low temperatures.

    I like it.

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.
