Researchers have developed a mirror that is mounted on buildings that reflect the heat, not just straight up, but in to space!
This isn’t a normal mirror, which would retain much of the heat itself.
The Guardian writes:
“In a rooftop comparison of the device in Stanford, California, scientists found that while a surface painted black reached 60C more than ambient temperature in sunlight, and bare aluminium reached 40C more, the mirror was up to 5C cooler than the surrounding air temperature.”
This could be a game changer. Energy consumption is a battle for humanity’s sake, hopefully this will alleviate some of our woes.
