Magic film. Scientists have found a way to cool entire buildings without using a single drop of energy

The miracle cooler is not only suitable for buildings, but it can also completely replace air conditioners in cars.

Scientists have calculated and concluded that cooling accounts for about 15% of all energy consumed. Air conditioning does not come cheap, and with climate change that promises only more hot and dry weather for humanity, the situation will only get worse over time, writes the Daily Mail.

In order to reduce the amount of energy consumed and not die from heat and stuffiness, scientists from the University of Ken Hee in Seoul began to develop a miracle tool that would allow you to cool the room without using a single drop of energy.

The task was not an easy one. The researchers needed to create a material that could not only block solar ultraviolet and infrared light, but also repel it from the surface at a wavelength that passes through the atmosphere.

According to project leader Eunkyu Lee, he and his team had to challenge themselves – it is not easy to develop materials that would meet both of these criteria at the same time. Moreover, scientists have set a goal to create a transparent material so that, if used on windows, it can transmit visible light.

Fortunately, the scientists succeeded. They created their “transparent radiation cooler”, which consists of four ultra-thin layers: silicon dioxide, silicon nitride, aluminum oxide or titanium dioxide on a glass base and coated with a polydimethylsiloxane film.

After, the scientists used machine learning and managed to optimize production. Scientists suggest that the miracle coating can reduce energy consumption by a third even on the hottest days.

By the way, the researchers suggest that the coating can be applied not only to the glass of a building, but also to the windows of cars or trucks, the new development will easily help to cool the interior of the car and replace the air conditioner.
