Paris turns the Seine into a giant air conditioner. Beneath the city, 100 km of pipes now channel river water through heat exchangers to cool 800 buildings - including the Louvre and Grand Palais! The way the system works is by transferring heat through closed loops, room by room, until it disperses back into the Seine. The plan is to triple the network by 2042, reaching all arrondissements and 3,000 sites as heatwaves intensify.
