Air conditioning. For some it's the best invention in the modern world. For others it's an example of American wastefulness and decadence.
Daniel Engber wrote a two-part piece for Slate Magazine on the pros and cons of air conditioning. He joins the show to talk environmental ramifications, health effects, and why the AC issue is a cultural symbol for the left.
Some facts on air conditioning:
-87% of US households have air conditioning
-Willis Carrier of New York invented the first modern electrical air conditioning unit, patented in 1906
-Air conditioning used to be much too expensive for the masses, but Carrier, a leading air conditioning and heating supplier, made a system for theaters that cost between $10,000 and $50,000. It was one of the few things proprietors sprung for during the Great Depression, and theaters were one of the rare places where the hoi polloi could enjoy chilly, artificial air.
