Stockholm Central Station harnesses the Human Body for Energy

Sciences

With energy becoming such an issue in the world, everyone is looking for renewable energy which is consistent with nature. With the population rising so much any source of energy seems small. But what if the people itself are the source? Body Heat!

How does it work? quite simply, the heat generated will warm up water running through pipes which will be installed in the station. The water will be pumped to the new building and used to heat the spaces inside.
