<pre>In the US, developed a passive anti-icing technology, which requires only light for work

The Massachusetts Institute of Technology developed an experimental technology for the passive prevention of icing surfaces. It is planned to fight with the water that is going to be fixed (for example, on the wings of aircraft or helicopter screws) using the energy of light, both solar and artificial. In the system, there are no moving parts, controls, nothing at all, except for several innovative materials.

The new protection against icing looks like a thin three-layer film. The most massive part, an aluminum heat-transfer device, is only 400 micrometers in thickness. Under it is a layer of thermal insulation and mounting surface, and on top everything is covered with a unique proprietary material. The MIT does not disclose its name and composition, only describe the properties: this substance absorbs 95% of the light incident on it, converting the energy of the photon motion into thermal energy.

The principle of operation is simple: if a lantern is shined onto the anti-icing coating, the top layer will be heated at the contact point first, which then transfers heat to a wide aluminum circuit, which in turn will heat the adjacent surface. Ice does not melt, the capacity of this passive plant is too small, but a thin layer of water forms between it and the coating. As a result, ice loses its adhesion to the surface, becomes brittle and can collapse when vibrations – instead of a dangerous ice crust on the wing of an airplane or a road, we simply collect very cold water.

The materials on which everything is based are still kept secret. The authors of the technology claim that their tests are successful, including tests in the open air.
