Chemistry World just released this news article about a paper describing an approach that facilitates electrolysis of salty or brackish water. The article quotes a reviewer from the University of Glasgow saying "It's definitely one of those papers that makes you wonder 'How come no one thought of that before'." I can second that reaction. I've looked into electrolysis of seawater before, and there are several issues that make it problematic. When I read of this new approach, I was slapping my head. "Of course! It's so obvious. Why didn't I think of that!"
