Pedal-powered Christmas tree

The city of Copenhagen in Denmark will go green that year where Christmas celebrations are concerned, and we're not talking about the color of its trees. In fact, their traditional Christmas tree set up at their City Hall Square will boast energy-efficient LED lights that are powered by humans, where 15 bicycles are available for anyone and everyone to pedal in order to capability all 700 LED bulbs dotted along the entire tree. Good way to keep warm in the freezing weather as well, eh?
