Comment on The first EV with a lithium-free sodium battery hits the road in January

  Hope they simply bought trolley buses and didn’t waste money on battery buses

  It’s such a waste to put batteries in inner city buses

    Yeah, and the cables would install themselves automatically.

      That’s better than the buses breaking down.

        Sorry but youtube experts and their google research are not a reliable source of information for me. It’s entertaining but it’s the last thing I would base city planning on.

    Trolley buses are a weird niche. They require permanent overhead cable infrastructure like trams do but don’t have the other benefits of trams - low rolling resistance and no tyre pollution. I figure if you’re going to install a trolley bus route you probably might as well install rail at the same time and get the benefits of trams. (Streetcars for the North Americans out there)

    Actually electric buses make a lot more sense, as the utilisation and environmental impact would be much greater compared to normal EV cars.

    Plus you are conveniently omitted mentioning the energy losses of the cables, the maintenance cost, the installation cost, etc.

      id be genuinely surprised if the energy losses of the cables are more than the energy losses of charging the batteries even if they are they are more than likely offset by the weight difference of batteries vs the weight of the cable connecting mechanism.

      Then there is the issue of range and the uptime of the vehicles while you can use a trolley 24/7 you have to charge the bev buses

      Then there is the issue of extreme weather cold or hot where due to AC and or heating and the temperature itself affects the range a lot

      Then there are the maintenance costs of the battery the power capacity since you need space for the batteries

      So all in all you exchange a bunch of negatives for the benefit of not needing overhead cables

      A trolley with a small built in battery for those last few miles you might need to connect but don’t want to pull cables is the best of both worlds.

      Hope that was a comprehensive enough dismantling.

        Source for your claims?

        Plus do you know how expensive it is to support the whole cable infrastructure, including personnel salaries, etc. I am not convinced your math is right, but feel free to prove me wrong.
