Engineers from the Massachusetts Institute of Technology (USA) have developed fast cooling that does not require energy or any other source of energy. It will not replace the thiedion units as it only cools down to 10℃ However, even this can help in the face of climate change and abnormally hot weather.
The design is in the form of a three-layer panel that can be sent on an object or a wrapper. The bottom layer is mirrored, it provides high-quality sunlight and visual heating from infrared radiation. In the middle lies the soi hydrogea, but the implementation and value of the upper soi is relatively
The water vapor rising from the plate freely passes through the porous airgel, but at the same time it blocks the flow of heat from the surrounding space, acting as an insulator. Airgel also includes sun rays. For the operation of the system, you only need to supply water according to the measure and value
