ResearchersatStanfordUniversity have developed a new material that can move heat out of buildings and into space. The material can cool buildings even on hot days
Thecoolingmateralis a ver thin sheet with many lavers that could be placed on a roof like solarpanelsHoweverinstead ofturning sunlight into energy as solar panels do, the material turns heat into infrared radiation.
ShanhuiFanisanelectricalengineering professor at Stanford University, He says that the panelshavealayer ofmaterialthatis like sandThe panels also act like a mirror, They take heat out ofbuldingsand reflectthe light from the sun. Both the heat and sunlight are sent 100 kilometers into outer space
The panelsarecooltothetoucheven inthe sun. Researchers say they can reduce the indoor temperature to nearly five degrees Celsius below the temperature outside
MrFan saysitis likehaving a windowinto space. He says the heat is sent directly into space withoutwarmingthe airBuildingsin developing countries that do not have electncity or air conditioning could use the panels. In areas where one is off-grid, there is a significant potentia benefitforstoring medicine oreven food. in many of these situations, being able to reduce the temperature is important. And this would provide a way to do it
The Slanfordresearchersdescribed theirtechnology in the science publication Nature. They saythe main problem is creating actual cooling systems using the high-tech panels. It may bepossible to develop a cooling spray technology in the next three to five years that could be used on existing solid structures。
2.【单选题】 Anewmaterial developed by researchers at Stanford University can
A. take out the heat to keep the building safe
B.absorb heat to keep the building warm
C.move out heat to keep the building cool
3.【单选题】 Which ofthe following statement about the cooling material is CORRECT?
A. The cooling material turns sunlight into energy
B.The cooling material changes heat to infrared radiation,
C.The cooling materalworks the same way as solar panels
4.【单选题】 In the sun. the panels can becometo touch
A neither too cold nor too hot
B too hot
c too cold
5.【单选题】 In areas where there is no electricity. the panels have the potential to
A. cook food and boil water.
B. store medicine and even food
C keep people warm.
6.【单选题】 The Stanford researchers present their technology_
A on the Internet
B in a TV program
C in a science journal
