There is many small ferries in UKwhich are basically a floating platform that get’s dragged through the water on cable. If you run that off an electric motor those can be quite efficent.
Maybe they are thinking about those.
What is producing the electricity?
That question can be applied to all the electric froms of transportation of the chart though.
But if we assume it’s the about the same energy mix as the tube or trams run off, then it isn’t that surprising. Volecity is major factor in the drag equation and ferries move very slow but have high capacity, so even with the additional drag, moving on cable should be closer to rail efficency than a ship, which has to use a propeller.
It’s still odd that it’s blow those other two, but I would have assumed they are in the same ballpark.
