The skyscrapers learned to cover the right color instantly to cool or warm

The authors stated that animals control their temperature through skin changes; the same principle can be used to cool the skyscrapers better.

Krills are marine organisms like shrimp that live in certain areas of the ocean, which are transparent, which means that ultraviolet radiation can damage their internal organs. In response, the krill developed a dynamic blackout system, which is pigment granules that move within cells under the skin, and they get dark when the street is too bright, and when the sun disappears.

Buildings also have facades and windows, but they're usually static, so sometimes there's too much and sometimes too little heat and light coming in.

So the authors are proposing a solution to this problem, and they have created a prototype fluid cells that are made up of a millimetre layer of mineral oil, trapped between two transparent sheets of plastic.

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

When the liquid is injected, a special pattern is produced that can be controlled by a digital pump; according to the authors, it can not only control the size and shape of the water in each cell, but also adjust the chemical or optical properties of the dye.

The new system reduces the energy consumption needed for heating, cooling and lighting to 30 per cent and compares it to the conventional systems used in skyscrapers.
