OK, it’s not magic. But here’s a promising technology that seems almost too good to be true. Aaswath Raman, an assistant professor of electrical and systems engineering at the University of Pennsylvania, has come up with a very cool idea – literally cool, that is.
Watch his TED talk to see how he began with a simple idea and developed it into an exciting, energy saving cooling device that may keep buildings comfortable in hot climates while reducing or even eliminating the energy currently used by air conditioning.
One day, we could be using the cold darkness of outer space to cool our buildings. In this TED Talk, physicist Aaswath Raman talks about 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.
