Scientists have learned how to cool objects and products without using electricity.

The new development of scientists from MIT may solve this problem. The thing is, they created a system that combines evaporative cooling, radiative cooling, and thermal insulation.

It is reported that it can provide cooling up to 10.5 °C according to the ambient temperature. At the same time, since the system is in the form of a three-layer panel, it can be safely placed on or around the object to be cooled.

The researchers cite the advantages of their design as not requiring electricity, and that some of the materials used in the system are “easily available and relatively inexpensive.”
