Cities want to bottle up your body heat

Cities harness the power of wasted energy

Together with

The Future. All around us is an abundant energy source that remains mostly untapped: heat. With the EPA determining 60% of uncaptured energy is lost as heat, there may be plenty of opportunities to not only harness an efficient power source that’s typically wasted, but also create a cycle of use and reuse.

Cities around the world are already turning heat into energy.

  • In Vancouver, the False Creek neighborhood captures excess hot water from drains and uses it to warm homes.
  • In London, heat is being captured from subway tunnels and redirected to homes.
  • In Glasgow, the body heat from partiers at a club gets pushed into colder rooms to balance it out.
  • In Stockholm, the city is collecting heat created by data centers.
  • In Germany, the heat from asphalt is getting absorbed to warm the roads in winter when they ice over.

Next up, scientists hope to capture any heat stored underground — a move that would both capture energy and cool groundwater so it doesn’t become a hotbed (sorry, we had to) for bacteria.

And with cities typically being seven degrees warmer than their surrounding areas, Insider notes the “urban-heat-island-effect” can be used as a force for good.
