Would you ski on top of a building?
Sometimes when there's no snow you have to make do with what you have. In this case Jesper Tjäder has the top of a zero emission waste to energy building in Denmark called CopenHill. CopenHill takes some 400 000 tons of municipal solid waste annually and turns it into energy and its sloping roof acts as a dry ski hill, climbing wall, and hiking slope. It's an interesting concept for sure.
