In this TED talk a physicist explains how to harness the cold of space on the Earth using conventional physics. How we can turn the cold of outer space into a renewable resource https://www.youtube.com/watch?v=7a5NyUITbyk
<<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). >> Harry
