Japan is testing solar-heated bus stops and benches. ☀️🪑 The units use phase change materials to absorb heat in daylight and release it for up to 12 hours after sunset, without fuel or grid power. Trials in Tokyo and Sapporo are aimed at reducing cold-related emergencies for people sleeping outside. The idea turns existing public furniture in high-traffic areas into overnight protection. If the pilot expands, cities could add a low-cost layer of cold-weather support through infrastructure that is already in daily use. #Japan #SolarEnergy #PublicInfrastructure #UrbanDesign #Hope
