How we can turn the cold of outer space into a renewable source

What if we could use the cold darkness of outer space to cool buildings on earth?

Aaswath Raman is a scientist passionate about harnessing new sources of energy, mitigating climate change and more intelligently understanding the world around us — by better manipulating light and heat using nanoscale materials.

In this mind-blowing talk, he 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.
