Here's Today's Feel-Good Story:
A US-China collaboration has made it possible to create the cheapest and fastest way to purify seawater to make it drinkable.
A solar-powered desalination tool can make 4-6 liters of clean water per hour, and a scaled-up version could sustain a coastal household year round!
“For the first time, it is possible for water, produced by sunlight, to be even cheaper than tap water,” said Lenan Zhang, a research scientist in MIT’s Device Research Laboratory. “This opens up the possibility for solar desalination to address real-world problems.”
