i really appreciate this angle. How much do the projections depend on battery chemistry or design choices? Seems like that could change the mineral needs pretty quickly
That’s very true, Nkosi. The mineral intensity estimate is based on current model designs in the US, and are in fact starting point “estimates”. As the robot design improves (as it scales up), these numbers are could change, plus or minus. However, I can’t think of a scenario where robots do not need any of these minerals at all. Also, some of the minerals are non-battery related like the REEs for permanent magnets or the copper for wiring.
Those are really good thoughts. If robot makers think more along this line—- trying to determine the sustainability aspects pre-design than post, there will be more value to generate (and not just profits). Thanks for engaging and continuing this conversation.

that makes sense. Even as designs change, these minerals are still needed.
I keep trying to picture all the bits that go into a robot, more than batteries. It's wild
I wonder how future tech and materials might change.

Thanks for taking time to read this!
