I hope we get rid of cargo ships that burn matter. But sails are too high maintenance to be scalable.
Last year, as an experiment I've launched a tiny solar-powered boat ([1]). Ultimately, it was too small and underpowered only making ~900km ([2]) before dying.
I hope to build a bigger drone boat next, hopefully with an ability to move up to 1 tonne of cargo. Apparently, it's possible, but (unfortunately) requires very delicate engineering.
For bigger boats solar does not seem to scale. It appears that nuclear is the ultimate future for megaships.
