# Aaswath Raman: How we can turn the cold of outer space into a renewable resource

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" — a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it — which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.
