Brine Projects and their feasibility, page-6

I am no expert. So just talking generally. As someone who has lived 30k inland of the west coast. I know weather patterns can be vastly different 30ms away. Chilie has water table probs. It is also a different elevation to Argentina. Then there is Bolivia

So I believe Argentina is in the Goldilocks zone. IMO
