Next they should replace the diesel engines with bigass electric motors, and put solar panels over every top surface of the vessel that they can, and even possibly on the sail-wings too. Wind and solar powered shipping would be a good combo since there are plenty of both out on the seas. Charge the boat batteries at port as needed, cruise while collecting solar power etc
I have a 4'x10' flatbottomed boat. Of the 40sq./ft. I cover 45% in solar to make a modest trolling motor go 6-7mph. Weight with myself, wife, battery, cells, misc. gear: 300lbs.
Solar ain't gonna get it on a cargo ship weighing 165,000 tons and a couple of football fields long.
Maybe something like diesel-electric that they use with trains with solar panels providing some of the electricity is a more realistic thought.
