It’s no secret that crowds cause temperatures to rise, but all those bodies generating heat could be a large source of untapped energy. Inspired by the hordes of people passing through Stockholm’s Central Station each day, a Swedish real estate company, Jernhusen, has found a way to harness the energy created by the 250,000 moving bodies to heat an office building across the street. As a result, the building’s energy bill has decreased by 25 percent.
