Submission + - Travelers' body heat to warm Swedish office block
paulraps writes: The heat from hundreds of thousands of hot and bothered people passing through Stockholm's Central Station each day is to be harnessed to warm a nearby office building. According to the man behind the project, Karl Sundholm, the 250,000 daily travelers will help bring down the office's heating bill by 20 percent. And if trains are delayed, no doubt that figure will rise.
