Disco pub gets electricity produced by people dancing at specially modified dance floor
All the flashing strobes and pounding speakers at the dance club are massive consumers of electrical power. So Bar Surya, in London, re-outfitted its floor with springs that, when compressed by dancers, could produce electrical current that would be stored in batteries and used to offset some of the club's electrical burden. The club's owner, Andrew Charalambous, said the dance floor can now power 60 percent of the club's energy needs.

Designer creates light-switch that changes colors to teach children how to save energy
Teaching the importance of energy conservation is the goal of this design from Tim Holley. He calls it Tio, and it's a ghost-shaped light switch that gives kids a visual reminder of how much energy they've used by leaving lights on. Tio starts out green and smiling. If the light is left on for more than four hours, he turns yellow and looks shocked. And if you dare to leave that light on for more than eight hours, sweet little Tio turns into a raging red hulk, complete with frowny mouth and angry eyes. But he won't just visually remind your kids about their energy habits; information from the light switch is sent to Tio's computer program so the entire family can see how they're doing. In a brilliant piece of visual positive reinforcement, Holley's program lets kids grow a “virtual tree” which gets bigger and healthier the more energy they save.
