Hehe, yeah I am a bit dubious wind powered shipping will win in a big way.

It is a “free” source of energy, so that is a huge plus. But I get those transit times are very best case times. I bet realistic times will be notably slower.

I also wonder how many tons of steel are needed to make enough ships to match the number of containers that are transported by the largest commercial ships… and I wonder at the speed of loading and unloading these things.
