Eco Trees

Hundreds of energetic dancers opened the world's first "eco" night club in Rotterdam. Watt Club, opened Thursday night, has the motto: "We want your energy," .

Every night, the club is ensure almost a third of the energy needed, through a particular dance. The dancers movements make the dance floor to vibrate, vibrations that are converted into energy. In the meantime, the dancers can see on the monitors from the DJ's stage, how much energy is produced.

In Watt Club everything is "eco", from the rain water used in toilets to the reusable plastic glasses from the bar.

Managers say that the club will save a huge amount of energy and money as to cover the costs of drinking water for 13,000 people.

Clubs owners from Berlin to Paris and from Sydney to San Francisco have already shown interest in the unique concept developed by the Rotterdam club.
