• Resumen

  • The article discusses a radiative cooling system developed by researchers at Stanford University, described in a 2014 article published in the journal "Nature". The system uses a mirror-like material made of hafnium dioxide, silicon dioxide, silver, titanium, and silicon to absorb heat from the air and emit thermal radiation which escapes into space. According to electrical engineer Shanhui Fan, the material could be used to cover the roofs of buildings and reduce energy consumption by air-condition systems.
