China's Cooling Technology Could Turn Entire Cities Into Refrigerators

China is testing a wave of large-scale cooling technology that could keep entire cities comfortable without leaning on power-hungry air conditioners. In this video we break down how China's cooling technology works, from heat-reflecting roads to paints and district cooling that pull heat straight out of buildings. As cities get hotter, more air conditioners run, more waste heat pours outside, and the cycle feeds itself. China is trying to break that loop with passive and city-scale cooling instead. What you'll see: Cool asphalt that cuts road-surface temperatures by 7-14 degrees C to ease urban heat islands Reflective cooling paint shown to lower indoor temperatures by up to 10 degrees C in Hong Kong tests Radiative sky cooling that sends building heat straight out into space District cooling: chilled water piped underground to cool whole neighborhoods Large-scale systems that can turn a metropolis into a giant refrigerator Could passive cooling technology be the real answer to a warming world?
