    fuels cells don’t and can never be made to work unless they invalidate the laws of nature somehow

    electrified public transport and cycling / escooter and walking are the only solutions

    ecars provide us paranoid few with a degree of energy resilience while civilisation continue to collapse but are in no way environmentally sustainable or green, the IPCC has fir devades said we need to move away from all cars.

    as an aside lots of chinese cars (I have one, i cycle as much as I can but here in Australia we’re car brained fools and it’s hard to live in rural areas sans cars, it was easy when we lived in the city) The chinese ecars often use LFP batteries and don’t need the cobalt used in NMC batteries. Still a shit load of other stuff like 100- 120kg of Cu for the wiring harness and toones of fossil fuels needed for the plastics etc etc

    The silicon carbon battery in my Motorola phone is good, they may be useful, solid state has issues over vibration that engineering may overcome.

    None of that matters as were to far along to change course let alone reveres, inevitably well cross too many topping points in the next decade or two and the collapse of civilization will be set in stone.

      …there are literally fuel cell electric vehicles already in production…?

      to tell you the truth, I think public transport is the real long term solution, I put fuel cells in there too because some individuals will need a car, e.g. disabled people, and I think it’s a big improvement to ICE and battery-based EVs both in terms of environmental/social impact and safety

        We are already at sodium batteries, so the environment argument is gone, and it was a weak argument, as if ICE and fuel cell cars are not made of mined metals, and hydrogen is not made from hydrocarbons. No way they could make enough hydrogen by electrolysis and if they did have the infrastructure to do that, it would be far more efficient to use EVs.

        public transport is the real long term solution

        Plus bicycles. They can replace and connect public transport in a great way for mid-range distances. Myself, I never had a car. I am mid-fifty now and cycle to work 14 kilometers, or 8.7 miles. And the only thing you need for a bicycle revolution in a city to happen are adequate safe ways - Paris, Copenhagen, Amsterdam, even Bogotá with its Sunday ciclovía are great examples.
