Local: Liquid nitrogen tanks on NYC streets?
Walking around the city, I frequently see large tanks of liquid nitrogen chained to a lamppost, with a rubber hose leading from the tanks into a manhole cover.
Does anyone know what these are for?

They've been around a while!
FYI Question NY Times
If this works so well to keep cables dry, why don't we see them in other cities?

As I think about this, however, I don't think I see nitrogen tanks too often in Brooklyn whereas they are all over Manhattan. Could the fact that Manhattan has lots of underground steam lines have anything to do with this?

I've never noticed them outside the city although apparently they're out there...
Nitrogen Gas Tanks on Plano Roadsides?
It makes sense they would be used mainly in humid areas or places with lots of steam tunnels.
Perhaps the density of cables means no room for the dewars in Manhattan's crowded utility tunnels.
