The article raises a few interesting points I didn't know:<p>- In SoCal there are several areas which have geothermal activity and correspondingly several electric plants based on that<p>- This geothermal activity raises both hot water and a fair concentration of a brine solution containing many metals<p>- The lithium isn't mined, they were getting it by processing this brine solution<p>Based on that, and reading many comments that modern batteries also needs lots of Co, Mn, etc... I wonder if the brine water coming up from this area is basically 'battery soup'? Seems like a lot of potential value that is already being pumped out of the ground by someone else - who considers it a waste product!
