New glass cold resistance, comparable to air conditioning

We may have had this kind of experience: In the summer, due to the obstruction of the glass windows, the burning light that hit the room feels like stuffy in the steamer. It is upset and irritated; it is cold and the windows look like a thick wall. Keeping the bright sunshine out of the house makes people feel extremely cold inside.

Although the advent of air-conditioning has freed people from the heat and cold, it has added to the already scarce power resources in modern cities. The red alarm of the power crisis has been heard in people's ears. Can we invent a new product that allows people to live warm and comfortable and save energy? Scientists have brought good news: British scientists have invented a glass that can act as an air conditioner. It can balance the temperature and make people feel cool in winter and cool in the room.

Why is this glass so magical? According to scientists, its peculiarity lies in the surface is coated with an ultra-thin layer material - a mixture of vanadium dioxide and tungsten. When the weather is cold, vanadium dioxide can absorb infrared rays, produce a warming effect, thereby increasing the indoor temperature; conversely, when the temperature outside the window is too high, the molecules of the two bonded substances undergo corresponding changes, reflecting infrared rays, and thus Indoor temperature becomes cool.

In this mysterious coating, the most “smart” core is the 2% tungsten contained in it. It can determine whether vanadium dioxide absorbs heat or heat. Speaking of this, perhaps you will be fascinated by this magical glass, but it still has some technical "defects". On its surface there is a layer of yellow-brown layers that looks dirty, which seriously affects its beauty. How to neutralize this color and make it clean is a problem that people face. However, scientists are optimistic about this, they expect that the glass will be available after 5 years, and the price is not much higher than the existing ordinary glass.
