Ingenious Gadget Could Harvest Battery Material From the Ocean

As cobalt mines run low, scientists think they could start harvesting it from the ocean. They have a plan to get enough for over 500,000 Tesla batteries.

New Source These days, most batteries for electric vehicles are based on cobalt — a dwindling element sourced from mines that often employ child labor and other unethical practices. Now, a team of MIT engineers say they’ve found an alternative, according to New Scientist: using a beach ball-like apparatus hanging from abandoned oceanic oil rigs, it may be possible to absorb […]
