    It’s not steam. It’s smoke from wood fired pizza ovens for the turtle men that live there. There was a cartoon documentary about them on tv a few years back.

    The New York City steam system includes Con Edison’s Steam Operations, a piped steam system which provides steam to large parts of Manhattan. Other smaller systems provide steam to New York University and Columbia University, and many individual buildings in New York City also have their own steam systems. The steam is used to heat and cool buildings and for cleaning and disinfecting. It is the largest such system in the world and has been in operation since 1882.

    Some big cities originally heated their buildings by producing steam in one one centralized building and delivering it to large buildings thru pipes underground. The steam you see is from leaking pipes in this antiquated infrastructure. It’s a very inefficient method if you ask me. Cities should offer these buildings low interest loans so they can update and be independent but they never take my advice

      District level heating is actually pretty efficient, some universities do the same thing on purpose to save on bills. Our relatively young city does it with the downtown skyscrapers for the same reason.

      The other nice thing is that when you upgrade the heating system to be less carbon intensive, you can instantly have a ton of buildings all jump instantly to fewer emissions too.
