WOW!

why cant they put giant sails on giant transport ships and save fuel?
i mean, if humans are to go to space, they will have to use solar sails, if there is a way to convert electric current and voltage into propulsion in space, even better, but sails are still there no matter where you go
they are cheaper to build and to maintain and the fuel for them is free
why am i the only one thinking about this?

We don't have any of these sadly

wind cant produce enough force anymore

sea transport is still the cheapest form of transport tho

Yeah we do, HMS Victory, Nelson's flagship at Trafalgar. It was posted earlier in the thread Still in commission

A FUCKING CURVE REEEE
