Cars That Think

I live in Manitoba , a province of Canada where all but a tiny fraction of electricity is generated from the potential energy of water. The manufacture of solar panels involves the environmental costs from mining, waste disposal, and carbon emissions. There is thus no longer a place for Big Hydro in the pantheon of electric greenery.

Nth Cycle says its electroextraction tech significantly reduces transportation costs for Li-ion battery recycling

Charged EVs

However, to extract ever more minerals by mining and dispose of the waste in landfills, would be to continue the practices that got the world into its current environmental mess. Nth Cycle works with battery recyclers and miners to recover production-grade critical minerals from separated electronic waste and low-grade mine tailings.
