liquid nitrogen for chiller to give N2 another use?

Lower consumption/60 for cooling but higher energy costs, but then doesn't use water for cooling. Could be neat. Could then require thermal storage for storing the LN2 from chillers.

Update 1 actually had Liquid Nitrogen (I don't recall if pre-update 1 0.4 also had it), but it was then removed with Update 2, perhaps for a reason. Still, I like the idea of having a use case for Nitrogen...
