We’ve had batteries with better energy density than fossil fuels for centuries?

Were the Roman’s just sitting on magic batteries but did nothing with them because no one had invented the iPhone yet?

Nope. Sails. They work great for moving people and cargo across oceans.

No fossil fuels required

Sail boats are amazing. Wtf. Have you never been in one?

[–] middlemouse@lemmy.world 0 points 2 hours ago (1 children)

Yes I have been, they are wildly impractical for real international travel

Apparently you don't know history.

That's a stupid argument, sail boats are not practical in the world we live in today. Their use in the past doesn't matter, because that world no longer exists.

Absurd amounts of material and food are moved quickly and safely by modern shipping , sail boats are not capable of this.

If sail boats were practical then somebody would be using them already.
