Think about the overall environmental footprint and $costs of acquiring mineral rights, mining, manufacturing (with very dangerous cancer causing chemicals) just the batteries.
Now consider that all on a scale that would even put a dent in a dent of the energy needs world-wide. Now consider all of the places and times where alt-E simply won’t work.
Now consider the environmental footprint and $costs of recycling and disposing of just the battery e-waste on that world-wide scale.
If any of the above is even possible. China controls 90% of the world’s REE.
A complete environmental disaster. And that’s just for the batteries alone.
E-waste is already a huge problem and will be the NEXT existential man-made threat to the world.
And a social justice problem because poor people and poor countries will have the waste dumped on them.
