Comment on Japan automakers play catch-up in EV race

  Batteries are unsustainable and have massive resource requirements. It's basically an obsession with "efficiency" while actually being extremely wasteful.

    You say that while promoting the idea of more inefficient energy transfer systems. Electric motors operate above 90%, traditional motors around 25-30%. Try to mitigate that with wasting more energy by creating an artificial fuel is even more wasteful.

      Solar panels are only 15-20% efficient. No one is going around saying we need to ban solar panels.

      Fuels made from solar power are the opposite of unsustainable. They are the most sustainable ideas possible. It is basically artificial photosynthesis.

        We don’t make fuels from solar power.

        Unless you mean hydrogen, which by itself is already 30-40% less efficient then just using the electricity directly in a battery.

        And that is without counting all the hydrogen that just escapes through any form of containment we try to keep it in.

        Where is the comparison to the solar panel? I’m comparing methods of propelling, you are comparing solar panels and?

        If you can use the energy more efficiently and choose not to it’s not sustainable (or at least not very smart)
