Sports fields could cool cities via rainwater stored beneath turf

Artificial-turf sports and playground fields may be more durable and require less maintenance than those covered in natural grass, but they also get very hot during warm weather. Scientists have devised a natural method of cooling them – and the cities… Continue reading Sports fields could cool cities via rainwater stored beneath turf

Cryo-cooling breakthrough slashes the energy cost of serious cold by 71%

Researchers have found a surprisingly simple way to build cryogenic coolers that reach near-absolute zero up to 3.5 times faster, or using about 71% less energy, than current gear. That’s big news for anything requiring seriously low temperatures.Conti… Continue reading Cryo-cooling breakthrough slashes the energy cost of serious cold by 71%

More transparent than glass, new material cools rooms and self-cleans

Having lots of glass surfaces can brighten up a room, but it also lets in too much heat as well as neighbors’ prying eyes. A new metamaterial is not only more transparent to light, but adds privacy, cools the room inside, and automatically cleans itsel… Continue reading More transparent than glass, new material cools rooms and self-cleans
