Harvesting human energy isn't a new concept, but Jernhusen AB breaks the mold by harnessing body heat to warm their own building. This human energy is collected in mass amounts thanks to Stockholm's Central Station, which is conveniently across the street from their office.
Proposed a couple of years ago, Jernhusen AB was finally able to make it come to fruition. Currently, their energy bill has decreased by 25 percent. This has been achieved by converting human heat into hot water, which is then pumped into Jernhusen AB's heating system.
