The Liquid Nitrogen Tanks of New York
The Liquid Nitrogen Tanks of New York – by Tom Scott
http://www.tomscott.com – http://twitter.com/tomscott – I was walking through New York and found a couple of seemingly-abandoned liquid nitrogen tanks on the street. Except they weren’t abandoned: they were full, making a very quiet hissing noise, and plumbed into… somewhere. I did a bit of research, and found out why they’re really there.
