Innovative heat tech could save England's swimming pools from closure

Public swimming pools facing closure because of soaring energy bills have been offered a lifeline via new technology to heat the water. Mark Bjornsgaard, the chief executive of the tech startup Deep Green, has trialled the idea in Exmouth, Devon. He has put a small computer data processing centre underneath the pool and the energy from it heats the water. The idea has taken off and up to 20 public pools could be upgraded to the heat system this year. "We built a small data centre in Exmouth leisure centre. Most normal data centres waste the heat that the computers generate. We capture ours and we give it for free to the swimming pool to heat the pool," Bjornsgaard told BBC Radio 4's Today programme.
