Skyscrapers have learned to instantly cover the desired color to cool or warm

The authors of the work said that animals control their temperature through changes in the skin. The same

The principle can be used to better cool skyscrapers.

Krill are marine organisms similar toshrimp that live in certain areas of the ocean. They are transparent, which means that ultraviolet radiation can damage their internal organs. In response to this, krill developed a dynamic darkening system - these are pigment granules that move inside the cells under the skin. They darken when it's too bright outside and brighten when the sun goes out.

Buildings also have a shell of facades and windows. But usually they are static, so sometimes too much comes in, and sometimes too little heat and light.

Therefore, the authors propose their own solution to thisProblems. They created a prototype of opto-fluid elements, which consist of a millimeter layer of mineral oil sandwiched between two transparent sheets of plastic.

Through a tube connected to the center of the cell, researchers can inject a small amount of water with a pigment or dye.

When liquid is injected,special patterns that can be controlled by a digital pump. They can not only control the size and shape of the water in each cell, but also tune the chemical or optical properties of the dye, the authors say.

The new system reduces the energy consumption required for heating, cooling and lighting by up to 30%. The authors compared it with conventional systems that are used in skyscrapers.
