street smoke

The smoke comes from steam pipes underground. The steam is used for heating apartments and for hot water.

I had a physics teacher in high school who joked: ';Class, we%26#39;re running behind schedule in the curriculum. See all that steam coming out of the ground? That%26#39;s thermodynamics. Next chapter.';

Saw on TV that the steam pipes get to 1000 degrees (F) and that the smoke you see is usually ground water hitting the pipes.
