I've been waiting to hear more about dancer-powered nightclubs since I heard about the one that opened in London this Summer, and it looks like one has opened in Rotterdam, and is now in business! When clubgoers hit the dance floor at Club Watt, the energy produced by their moving feet lights up the LED dance floor.
Other sustainable practices go on besides the booty shakin' as well, like using a rainwater catch system to use in the toilets.
You know what I'd like to see? A Dance Dance Revolution-like pad I can use in my house to party on and power my casa. My electric bill would disappear!
