  • This is just the same false dichotomy you’ve been presenting all the way along: starve or sell out.

    The undeniable and obvious fact you’re avoiding is that loads of people have jobs that they find satisfying in a “life well lived” kind of way. There are loads of corporations who’s employees believe in what they’re doing.

    Your timed piss break anecdote is not an example of a satisfying job. A job where you make minimum wage is not an example of a satisfying job.

    It doesn’t take years to get into another field, and you don’t start at the start because you take all your skills and experience with you, obviously. I’m in my 40s, young family, working on a postgraduate degree in something tangentially related to the field I’ve been working in for 20 years. I do find my current job satisfying, I’m just weary of it. People can and do change professions all the time.

    Objectively, this is very much a case of “I’ve tried nothing and I’m all out of ideas”.

    Like I said at the start, you don’t get a free pass just because you’re not a CEO.

  • I never said anything about not benefiting a corporation - you seem to have imagined that.

    Some corporations have shit objectives, others do not.

    There are loads of people who work for companies and really believe they’re making the world a better place through their work.

    You’re trying to present an argument that you need to work for an AI company or whatever to put food on the table, but it just doesn’t stack up. Plenty of people are not starving and are not doing that for a living.

  • The maximum weight for a tractor-trailer rig in the United States is 80,000 pounds, 40 short tons or 36.36 metric tons.

    I’m not sure what you’re getting at with this. Here in Australia road trains haul 90 metric tons of grain and fertilizer all the time, that doesn’t include the weight of the trailers.

    Regardless, I’m not quite sure what you’re trying to illustrate - your example of a “streamlined vehicle” undoubtedly consumes a lot more diesel than your example of a vehicle which is not streamlined. Isn’t that antithetical?

    In terms of torque, EVs have a significant advantage.

    Yes, but a “truck” with a 4 ton towing capacity obviously needs motors with more torque than those on a tesla.

    The additional energy required to accelerate the additional weight up to speed isn’t that much of a problem as an EV will get that back with regenerative braking. Well, some of it.

    As little as 5 to 10% on the highway, not particularly significant. Installing regenerative brakes on a trailer is a lot of additional cost and complexity.

  • I don’t know enough about physics or cars to really rebut you but this doesn’t seem plausible to me.

    I don’t think aerodynamics are particularly relevant to towing? Prime movers (tractor trailers?) are about the least aerodynamic vehicle there is but they regularly tow more than 100 tonnes at highway speed.

    If I had to guess I’d suggest the primary problem is the relationship between system weight of the vehicle and load, battery capacity, and the battery’s weight. As in, if you want to be able to cart 1 ton for 200km then the additional battery requirement is another 300kg so that’s really only an extra 700kg so you need more battery and heavier frame and so on.

    Another problem I suppose, and I emphasize that this is supposition, is optimising motors for both torque and speed. The torque required to break inertia with lots of weight in sandy or muddy terrain.
