Could London's underground rivers provide heat for the buildings that lie on the surface?
Scores of streams and rivers once flowed through London into the mighty Thames.
Their waters once powered our city - providing transportation, drinking water and power to drive mills. As the city grew the rivers were built over.
But what if we could use them to power our city once again? Through the magic of heat pumps, London’s lost rivers could provide low cost, low carbon heating and cooling to the buildings above.
Possible and Scene have been investigating this possibility. There is a huge opportunity to harness our ancient rivers once again to power our modern world.
