“Solar steaming” is an eco-friendly form of water purification in which sunlight is used to heat tainted water, turning it to steam which condenses back into liquid. That clean liquid is then collected as drinking water. A new system offers improved performance, and it copies the structure of the rose flower. Led by Assoc. Prof. […]
