Curio #480 - Salt that breathes
An amusing fact for October 26, 2014 from Justin Kitch, Curious CEO
Imagine if scuba divers or lung patients could replace their heavy oxygen tanks with a few teaspoons of salt. Huh? Researchers in Denmark say they’ve invented a crystal that can do just that! This new compound is capable of pulling oxygen out of the air, and even out of water. Just one spoonful of the material can suck 99% of the oxygen from a room. The crystal is a salt made from cobalt. It can hold oxygen that is 160 times more concentrated than what we breathe. But the best part is that it can release the oxygen in low-oxygen conditions, similar to how hemoglobin works in our blood. So a scuba diver could potentially leave the tank above water, and let a handful of crystals absorb and release oxygen from the surrounding water. My brain is getting oxygen deprived just trying to grok this.
