Pioneering wind-powered cargo ship sets sail
(www.bbc.com)
This is a most excellent place for technology news and articles.
Wow, they invented sailing!
Yes, but I guess the improvement is that you can save some power from the wind so you can sail when it dies down.
We used to have another solution to keep the ship moving with no wind, but stupid woke culture put a stop to having hundreds of galley slaves chained to oars on the lower decks.
