Feeling the heat?

If so, you might want to look into Japanese Kuchou-fuku's air-conditioned clothes. The shirts and jackets keep the wearer cool with two small fans sewn into the back of each garment. The fans are powered by a pocket-sized rechargeable battery pack.

They aren't the most fashionable thing I've seen, even in any of the 10 different styles and a variety of colors, but they do help the environment because they use about 1/50th the energy of a small air conditioner. If you don't mind that you might look like a human blimp, you can get one of these shirts for 11,000 yen ($96).
