An innovative heat recovery system would capture the waste heat from train tunnels for use in cooling and heating homes.
Developed by a team from EPFL, the heat recovery system would be made up of plastic pipes filled with a heat-transfer fluid embedded in the train tunnel. The warm air of the train tunnel—the result of the myriad of electronics, warm-blooded passengers and train-induced friction—would heat cold water pumped through the pipes for potential use as household heating. And, according to the team, the system could also work in the summer, bringing the cooler underground air to the surface, and perhaps even chilling a local ice rink.
