Global warming continues to be a serious issue that still threatens the world leaders. Slowly temperature of the earth is rising to potentially dangerous levels; however aftermaths of energy costs of new air conditioning investment will indeed increase global warming to greater extent. To relieve our planet from the problem, Stanford engineers have invented revolutionary coating material in form of the hi-tech mirrors that could help in cooling buildings, even on sunny days, by radiating heat away from the buildings directly into space.
The researchers say that the mirrors are made of ultrathin, multilayered material to be cost-effective for large-scale deployment on building rooftops. The mirrors are invented to reflect 97% of the sunlight away from the building (on which it is installed), whilst releasing excessive heat back into space. This new technique is called the photonic radiative cooling that can be used without any use of electricity, thus saves energy.
The combined reflectors and radiators dropped temperatures inside the building by 4.9°C, as compare to the outside temperature. But these mirror radiators will not make the natural atmosphere warm as the heat released will be similar to the atmospheric conditions in space. This amazing technology has raised our hopes to control global warming without any negative impact on environment. Hopefully, it’ll be the permanent answer to all global warming issues.
