The Problem: All the flashing strobes and pounding speakers at your favorite dance club are massive consumers of electrical power.
The Solution: Harness the energy on the dance floor. Bar Surya in London re-outfitted its floor with springs that, when compressed by dancers, produce electrical current that is 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 power 60 percent of the club's energy needs.
Eco Craziness: 1/5. Innovation and creativity earn this dance club a different kind of rave.
