The Stockholm Central Railway Station is not only the largest station in Sweden but also the largest travel center in the Nordic region with hundreds of thousands visitors rushing to catch trains and subways or simply visit a big number of shops and stores inside.

  Every day through the Station pass around 250,000 of people and their body heat will be used to heat a new office building nearby.

"So many people go through the Central Station... We want to harness some of the warmth they produce to help heat the new building," Karl Sundholm, of the Swedish state-held property administration company Jernhuset, told AFP.

  The mechanism would contrive that the body heat, which would be channelized through a ventilation system, warm up water and this water would be pumped through pipes over to the new office building, a small hotel and a few shops and is expected to be completed by the beginning of 2010.

  The entire set-up has been estimated to require a fund of $31,000. This project is expected to cut down heating costs by 20% for the new building and, if successful, would point out a great way of conserving energy.
