Breakthrough Material Enables No Electricity Sterilization Will Save Thousands of Lives | NextBigFuture.com

Optically transparent aerogel is essentially a lightweight foam made of silica, the material of beach sand, and consists mostly of air. It reduces the rate of heat loss by tenfold. This transparent insulating material is bonded onto the top of off-the-shelf equipment for producing solar hot water. A copper plate with a heat-absorbing black coating is bonded to a set of pipes on the underside. As the sun heats the plate, water flowing through the pipes underneath picks up that heat. But with the addition of the transparent insulating layer on top, plus polished aluminum mirrors on each side of The post Breakthrough Material Enables No Electricity Sterilization Which Will Save Thousands of Lives first appeared on NextBigFuture.com.
