A team of engineers has created a advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage -thin material that could help keep buildings advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage . The team is from the University of Colorado Boulder in the USA. Engineers from the advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage developed the revolutionary new advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage , that is very advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage and can cool objects even under direct advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage . The material does not need energy to work nor does it need water to help keep things cool. The engineers say the new material could provide an advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage to air conditioners, which are advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage to run and need a lot of water. The material is unlike anything found in nature. It is a glass-polymer advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage that is just 50 micrometers thick. That's advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage thicker than the aluminium foil we use for cooking. The engineers explained how their advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage material works. They said when it is put on top of advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage , two things happen. The first thing is that it cools the advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage underneath by reflecting the Sun's rays back into advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage . At the same time, the second thing happens - the material removes the object's own heat and sends that into the advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage . An engineer said: "The key advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage of this technology is that it works 24/7 with no electricity or water advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage ….We're excited about the advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage to explore potential uses in the power advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage , aerospace, agriculture and more." Another researcher said: "Just 10 to 20 square meters of this material on the advantage air answer cool expensive hybrid industry material new object opportunity rooftop slightly something space sunlight super thin university usage could nicely cool down a…house in summer."
