Impossible Metals ocean mining robot
(Picture: Impossible Metals)The push for green transport has brought with it greater demand for the metals that go into EV batteries.
Constant mining of the land for cobalt, nickel, lithium, and copper comes with its own issues around environmental and human-rights abuses. As it turns out, many of these valuable little rocks (known as polymetallic nodules) are lurking on the ocean floor. Enter Impossible Metals, a robotics startup that says it can extract these underwater metals in a sustainable way using its autonomous machines.
