My entire adult life I've worked on #decarbonization technologies guided by the question, "what can I contribute to humanity to help evolve us into a more advanced alien species?" #Lithium for batteries was a good place to start.

So I spent half a decade developing technologies and natural resources for a new world that emits less CO2 and requires less mining than the old world. However lithium will always have a tiny footprint even at full scale. That's actually the point.

Meanwhile, we produce almost as much structural metal today as we produce coal. And because metal makes advanced alien species possible, it will be produced forever. Even "as time goes to infinity", primary metal will be needed because nothing is "infinitely recyclable".

Advanced alien species don't stockpile bauxite residue slurries behind tailings dams and they don't destroy their indigenous sites for iron ore.

They don't carry around deadweight in their vehicles making their transport system unnecessarily inefficient, nor do they predicate trillions of dollars of trade and all of national security on a coal co-product of semi-coking ovens in Fugu County, Shaanxi Province, China.
