Hundreds of years of innovation in water travel, and we come back to a sail. Granted, a metal one, but still a fucking sail.
There's a reason they quit, though. It's slow and doesn't let you go in every direction. The midline area of earth has winds that move mostly towards west, while the north and south portions blow mostly east.
For those curious, these sails save 12 tons per day. The average cargo ship uses around 200,000 tons per day, so around 6% better fuel economy.
Thanks for putting it into relation to daily use. 200,000 is not realistic though. Just had a google and found this source citing up to 400 metric Tons/day

12 is 0.6% of 200,000 btw
0.006%
This is the correct calculation (although the 200k figure is wrong)
