I wonder what can have better potential efficiency, a classic solar panel and an electric boiler/dryer, or these devices?

I've wondered why desal hasn't also paired up with ocean mineral extraction. It seems like the two would go well together. Even when talking about RO, you'd think diverting all or part of the brine water for evaporation would reduce the cost of extraction. You'd have water with more concentrated minerals which would give you a higher yield per evaporation cycle. Also, it'd be nice if we could bring back magnesium extraction from ocean water.

No critical thinking at all in this article. So you take out the water and 50% of the lithium. You still haven't addressed what happens to the remaining NaCl, which was the main headline. The headline should be "thing can extract lithium from sea water at 50% efficiency. It also produces potable water."
