Something as a tangent to Electric vehicles...

Researchers at King Abdullah University of Science and Technology developed what they believe is an economically viable system to extract high-purity lithium from seawater.
There have been other attempts to extract Lithium from seawater, but the other experiments didn't produce as much lithium. (Note that this is just at the research phase, so it is possible that this may never end up being used in an industrial setting.)
Given the need for Lithium-Ion batteries in electric vehicles, this could be useful... china is one of the top lithium producers, and they are often caught up in various geopolitical conflicts. And extracting lithium from seawater would eliminate the need to build more mines.
