A tethered ring would be cheaper, and also possible
Have them down below on exercise bikes like little hamsters.
An interesting alternative to sails are Flettner rotors. They're pretty much just rotating pillars, and are being tested on some cargo ships to reduce fuel consumption.
This comment is just classic Lemmy. Do you think customers would accept their cargo just turning up whenever, depending on what the wind is doing? Why do you think we went away from sail in the first place?
Not to mention the air draft of such a vessel, or the fact that sails interfere with loading cargo.
There are sailed powered logistics ships! Here's a grain ship that just launched. There are also companies that produce inflatable or deployable sails to reduce fuel consumption in favorable winds.
Ultimately there will be a need for chemical energy or similarly dense energy to move a ship. The wind doesn't always blow, and when it does it won't always be in the direction you want. Nuclear is certainly an interesting option.
They can just add sails to augment the current engines. I read somewhere years ago that it was tested and found to reduce fuel consumption by a lot.
In that case, why isn't it more common?
