A thin film that fills up solar heat and is still cold, to de-ice future discs. The heat is released by a short heat pulse.

What has man tries everything to de-ice windscreens of cars quickly. There was heat, quickly warm air onto the glass blew, sprays that could melt the ice and the heater. Nothing has generally prevailed. Many people still take minimal visibility before the ordinary heating ensures a clear disc.

Institute of technology (MIT) have now found the solution scientists at the Massachusetts in the American Cambridge. Sponsored by the Munich-based automaker BMW, they developed a very thin foil, which stores the heat rays of the Sun, without heating itself. The particles of light destroy the order of the molecules in the plastic film. A thermal or acoustic pulse suggests they retake their rightful positions. Thereby, it emits the baskaran property previously stored heat. The film could be integrated into safety glass. This consists of two halves, between which there can are already slides, reflect the infrared rays. This works also with the Cambridge film, because it is much thinner than one millimeter.

The material expert Jeffrey Grossman, Professor at, and its employee David Zhitomirsky and Eugene Cho have developed film. While they had a completely different goal in mind: A solar cooker, which stored heating in a way to get at your fingertips can be around to cook dinner after sunset. This cooker should store the warmth on cold way to save voluminous layers of insulation, as they are necessary to prevent approximately, the cooling of hot water.
