How Much Energy Intensity Is It?

There are about forty commercially usable elements dissolved in sea water at significant concentrations, lithium being one of the higher ones. There's also tons ofa copper, there's some gold, there's cobalt, nickall and lots of useful things - but we'll never use it all. The more energy intensver a process is, the more expensive it is. So ad think probably in a thousand years we'll be on to something more advanced than lithiamine technology. It will happen when the market value of lithium will support thats right prize. And of course, that meansit needs to be cheap enough.
