I forget the article I read about 3 years ago about a modern cargo ship using sails to reduce the amount of fuel they use. Can’t find it now but if I can find it I’ll try and post it in an edit here
I saw some science-entertainment videos. There’s also these rotating “sail” cylinders.
Most of it sounded not viable for mass transport and more like PoC or tryout state.
