    but I don’t see how it’s viable

    It was viable enough in the 1800s.

    for a few uses like shipping and aviation

    Yeah … aviation in particular will probably be mainly fossil fuels for a long time to come, because it really needs energy density.

    The solution there is just for people to fly less. (Which could be partially accomplished by having fast electric train routes.)

      If the only reason oil is being extracted is to power aviation, the cost of fuel, and hence of flying, will be higher and the volume of flights will go down accordingly. Win/win for everyone but the oil and tourist industries.

      It was viable in the 1800s because it was the best method available. We don’t use it today because it ultimately costs more. A wind-powered company would have to compete against others using extremely energy-dense fuels that enable hundreds of times more cargo (between increased speed and increased capacity) for the same time and money.

        So, in other words, it’s perfectly viable … just not economically viable.

        That’s a failure of our economy, not of the technology. Perhaps if all the externalities of fossil fuel emissions were included in the cost of fossil fuel shipping (say, with massive taxes on fossil fuels to fund environmental efforts and carbon capture), that would change the balance.

          I’m not sure sail is even viable, as in not compatible with modern capitalism. Most shipping has some sort of schedule or deadline, and you can’t just take an extra month “ because we were becalmed”

          Although I was also going to object based on more complex harbors, but that leads right to battery power. Right where all the shipping, all the emissions, all the pollution comes together where it can harm people ……. Why not battery-only, while in harbor?

            And for that matter, battery power as a backup when you’re becalmed as well.

            Hell, even fossil fuel power as a backup would be better than fossil fuel power as the main and only power source.

          That’s like saying, “So it’s perfectly possible … just not physically possible.” If you cannot afford to do something, then you can’t do it. It’s freaking tautological.

            “Can’t afford it” is very, very different than “not physically possible”.

            If our economic system changed, then it could be perfectly viable again.
