I’m currently studying for the theory and then the practice for the license and I hate it… But since I’m unemployed for like half a year now maybe it will give me more chances to get hired. Still I will avoid driving as much as possible, being on a highway scares me and I’m afraid of having an accident. Plus I wear glasses and I’m not sure if my reflexes or peripheral view are good enough…

So, what’s your reason to not drive a car… money? For the environment? Are you afraid? You really don’t need to?

    And honestly batteries are too expensive today lol, I manage a farm and I couldn’t imagine the electricity costs for charging all my tractors everyday, not to mention the need for more because they couldn’t do the jobs as long as my diesel tractors could. We use farm diesel which is significantly cheaper than road diesel and its cheaper than charging multiple tractors

        One difference, you lose about 10% of the energy density with hydrogen, so you’d have to refuel a little bit more often. But I think that’s close enough that it’s good enough for most applications.

        Yeah. I think most people are not aware of the energy requirements of industrial machinery. There’s a huge difference between gliding a car across well maintained concrete with wheels, and moving literal tons of earth out of the way.

        There is a reason we have not seen backhoes, tractors, bulldozers, moving to batteries. Batteries just are not energy dense enough

        I’m confused by one thing, we should be seeing countries without domestic fossil fuels moving to hydrogen for their Air forces. Just as a domestic security issue. Unless they’ve been doing it really quietly, I’ve missed it. There is one demonstrator flight transatlantic flight from France to the USA using hydrogen fuel. But that’s all I’ve seen. I would really expect China to be going 110% on hydrogen for their air force. Germany too for that matter. Any rich country without domestic oil, which is fair few of them
