Plastic wraps is a futuristic material that has been found to have the potential for cooling houses and power plants even without energy. This power-less cooling system does not need any energy source like water, sunlight, and fossil fuels. Instead, a superthin material that is slightly thicker than an aluminum foil is used to radiate sunlight, thus creating a cooling effect.

According to Live Science, the material is just like a plastic wrap that reflects heat. A group of researchers from the University of Colorado Boulder, headed by material scientist Xiaobo Yin, conducted the experiment using the principle of Radiative cooling. 

During the day, the Earth is heated by sunlight, but during night time it sends back infrared light into space and cools itself in the process. Based on that principle, the researchers created a material by combining three compounds to form a sheet that is just like aluminum foil, although thicker.

The resulting material is a transparent polymer known as polymethypentene that looks like a roll of plastic wraps. In between the plastic are hardly visible glass beads wrapped in the bottom with a thin film of reflective silver.  

This technology advancement could make air conditioning obsolete.
