I'm Very curious about how does this work???
Read the text below,
It's on the stickers pasted on the Merchandise Mart revolving doors..
Welcome to world's largest LEED-EB Silver Certified Building where every revolution reduces pollution..
FACT: If our 25,000 daily visitors used the revolving doors the pollution equivalent of 50 car trips from New York City to Los Angeles could be eliminated every year..

Possibly it's using the door revolutions to generate electricity and feeds that back into the grid? It'd be more apt to compare to how much less coal would need to be burned for the electricity, but maybe gasoline energy is a more familiar comparison?
