New air-conditioning design cools without using fossil fuels

Is the future with radiative cooling?

Linda Cicero, Stanford News
  • Scientists at Stanford have developed what is essentially a fossil-free air conditioner.
  • It absorbs solar energy, creates a heat sink, and releases that heat through radiative cooling.
  • The device is still in development.
