Submission + - Professors claim passive cooling breakthrough via plastic film (economist.com)

Submitted by charlesj68
charlesj68 writes: An article in the Economist discusses the development of a plastic film by two professors at the University of Colorado in Boulder that provides a passive cooling effect. The film contains embedded glass beads that absorb and emit infrared in a wavelength that is not blocked by the atmosphere. Combining this with half-silvering to keep the sun from being the source of infrared absorption on the part of the beads, and you have way of pumping heat at a claimed rate of 93 watts per square meter.
