Cooling by Passive Cooling - New Tech
New Type of Energy - Passive Cooling Source: University of Buffalo New Innovation Incorporating Solar Energy and Outer Space This is new energy innovation from engineers at the University of Buffalo. A green, renewable way to keep buildings cool in urban areas. It's a passive cooling system that absorbs heat and beams it as heat radiation to outer space, while keeping the environment around the system cool. What's remarkable, this system is self-sustaining and requires no electricity or batteries to power it. Unique and Inexpensive The device consists of an inexpensive film composed of polymer/aluminum that is put in a box inside of what the engineers call a "solar shelter" that they also invented. The special film absorbs the heat from the air and keeps the surroundings cool. The solar shelter serves two purposes: blocking incoming sunlight and beaming the heat into space through a narrow beam passageway as thermal radiati...
