Lithium ? We don't need giant Lithium ion batteries.... we need something better. Something safer and something people can actually afford to use in their homes. We need to stop creating and storing energy and then transporting it thousands of miles by wire. We need something safe that can be used in every home and every home have the ability and technology to create and store their own power safely.
Musk says he will solve the energy crisis in Australia with his giant Lithium batteries. I think we need smarter people developing a better technology than lithium.
Maybe something we have in abundance here on earth. Maybe something like Salt water....
