  1. Authorities in NYC are told to inform anyone that asks that it is the subway, although every major city has a subway and theirs doesn't release steam :D

  2. I don't see how this is greener since steam and electricity both require the same thing to generate them and that will be whatever fuel is used to boil the water, be it coal, gas or uranium. I do see how taking the turbines and generators out of the equation reduces loss but steam loses even more energy in transit, it basically heats the ground and subways below Manhattan through escaped heat. Scepticism aside though it is a very cool and unique system that is an integral part of NYC's image as no movie set in the big apple would be complete without that one scene of a steam-filled alleyway.
