    Until you realize that the energy requirement is also different. Land transport in general is very inefficient. Ship is in fact one of the most energy efficient means of transport.

      I don’t disagree but every time I’ve seen a diesel engine on a cargo ship it was absolutely massive.

        Size wise, it is small relative to the ship size. Look at car engine. How many % of volume is taken up for the engine and fuel tank of car? I think it is close to 30-40%

      194 nautical miles isn’t terribly far, though. For port to port, sure. For oceanic shipping, I don’t think 194 is going to cut it. I think we will probably have to do SMRs or efuels to really cut cargo ship and cruise ship emissions when crossing the Pacific or Atlantic. Though I don’t know where nuclear powered shipping (in non-military applications) is in terms of progress.

        I do think that cargo ships are the one vehicle where solar panels would make sense though. Add that and a sail, and you should be able to increase the range considerably.
