Superwhite paint can cool buildings even in hot sunlight

A new superwhite paint is so reflective that it can cool a surface to below the surrounding air temperature, even under sunlight. It could help reduce the use of energy-intensive air conditioning in hot countries Source: https://www.newscientist.com/article/2257749-superwhite-paint-can-cool-buildings-even-in-hot-sunlight/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…

Geoengineering Wouldn’t Be Enough to Stop Greenland From Melting

An anonymous reader quotes Gizmodo:
When the Greenland ice sheet went into a record meltdown in the summer of 2019, it raised a very terrifying specter of the future. Here was a 12.5-billion-ton mass of ice — one that’s been melting at a quickening pace since the 1980s — melting in a way scientists didn’t expect to happen for decades. While the…

Is daylight time worth the trouble?

This is the weekend we “fall back” here in the U.S. Are you glad? Sad? Mad? Advocates say daylight time saves energy and wins wars. Studies show injuries and illnesses rise when clocks change. Source: https://earthsky.org/human-world/is-daylight-saving-time-worth-the-trouble…

Scientists Are Using the Cold of Outer Space To Rethink Air Conditioning

A California-based company called SkyCool Systems is in the early stages of manufacturing a cooling system that’s more energy efficient than anything humans have used for a century. It’s doing it using radiative cooling, a concept that was used in the Middle East and India hundreds of years ago. Quartz reports: To understand how radiative cooling works, forget for a moment…
