Advancements in Magnesium Alloys and Magnesium Thixomolding will lead to huge increases in Magnesium demand. How will we increase the magnesium supply to meet that demand? In my view, the best way is by extracting magnesium from seawater by going back the future to resurrect Dow and Norsk Hydro's processes - and Magrathea's doing exactly that.
