    What would it take to make N2 condense into a liquid?

    Look up 'latent heat' and study it... you will understand...

    Yeah, kind of hard to get N2 to condense.


    Then again, there are CO2 "transcritical" systems that use CO2 and it doesn't actually condense, either...

    Liquid nitrogen is used as a coolant quite often is ultra-low temp applications. But it is dumped to the atmosphere in those cases.
