Ministry for the Future is a book chock full of optimistic can-do idealism. One of the ideas floated is container ships with (on-ship) wind and solar renewables that just move really really slow. Personally I think for many transportation needs that would be find. And they start chopping up bug ships to make smaller more regional ones. Which jives with the analysis here. But given that bigger boats afaik almost always are more efficient moving through the water (short of hydrofoiled or wing-in-groumd craft), I didnt totally get this notion.
