If anyone else was confused why those pictures were of giant tubes and not canvas sails, you are not alone. Apparently those are some version of "Suction Sails". The vendor's website has a graphic that explains it, though it was fighting my ability to scroll.
The rending of the Maersk ship really strains the concept. If the containers are stacked that high, would it not block the wind going to the solitary sail?
Growing up as I did in an old seafaring town, quite near Ahab's ports of call, I love the romance of the sea and I listen exclusively to sea chanties.
For low-value and bulk cargo, ships make sense, and modern computer-controlled sail trim and wind energy harvesting probably makes a great case. But high value cargo is largely today shipped by air. Nvidia wants money for its chips ASAP, too valuable to sit around non productively while being steamered. Maybe with surplus wind energy they could mine bitcoin while en route?
A sort of related topic, about 20 years ago during peak farm-to-table "buy local" fashion, the NY Times pointed out that lamb shipped from New Zealand (where is that on a map, I can't find it?) to New York City arrives with a lower carbon footprint than lamb delivered by trucks from nearby upstate NY farms, such are the economies of scale in shipping.
But now, blow me down me hearties, I look forward to dining on New Zealand lamb carried to my door by the winds of fortune!
If there was a direct and maintained electric train route + stronger food regulation in the US you could dine on fresh local produce with a lower carbon footprint.
International cooperation and trade is great, but in the US specifically the economic behemoths have used globalization to paper over the real problems that we face at home (we haven't truly invested in infrastructure in a long time, the meat we produce is rejected on health standards abroad, etc). I doubt the smokescreen will last much longer with Trump et al blowing up international agreements.
