Laser-Etched Metal Purifies Contaminated Water Using Sunlight With Greater Than 100% Efficiency

Good News Notes:

By etching metal with ultrashort laser bursts, Rochester researchers demonstrate a way to purify water without wasting energy.

Amid the coronavirus pandemic, people in developed countries are assured of ample supplies of clean water to wash their hands as often as needed to protect themselves from the virus. And yet, nearly a third of the world’s population is not even assured of clean water for drinking.

University of Rochester researchers have now found a way to address this problem by using sunlight—a resource that everyone can access—to evaporate and purify contaminated water with greater than 100 percent efficiency.”
