Researchers at Stanford University have developed a new material that can move heat out of buildings and into spaceThe material can cool buildings even on hot days
The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panelsHoweverinstead of turning sunlight into energy as solar panels dothe material turns heat into infrared radiation
Shanhui Fan is an electrical engineering professor at Stanford UniversityHe says that the panels have a layer of material that is like sandThe panels also act like a mirrorThey take heat out of buildings and reflect the light from the sunBoth the heat and sunlight are sent 100 kilometers into outer space
The panels are cool to the toucheven in the sunResearchers say they can reduce the indoor temperature to nearly 5 degrees Celsius below the temperature outside
MrFan says it is like having a window into spaceHe says the heat is sent directly into space without warming the airBuildings in developing countries that do not have electricity or air conditioning could use the panelsIn areas where one is offgridthere is a significant potential benefit for storing medicine or even foodIn many of these situationsbeing able to reduce the temperature is importantAnd this would provide a way to do it
The Stanford researchers described their technology in the science publication NatureThey say the main problem is creating actual cooling systems using the hightech panelsIt may be possible to develop a cooling spray technology in the next three to five years that could be used on existing solid structures
1The material can cool buildings only on cold days[答案]F
2The material turns heat into infrared radiation because it is a very thick sheet with many layers that could be placed on a roof like solar panels[答案]F
3The heat of the buildings and sunlight are sent 100 kilometers into outer space by the panels[答案]T
4The offgrid areas may use the panels to reduce the temperature of buildings to store medicine or even food[答案]T
5A cooling spray technology may be developed in the near future that could be used on existing solid structures[答案]T
