Surprising the Chinese did not go to nuclear to power this ship.
Annual fuel costs alone would make for a very quick payback.
And if a uranium-fueled nuclear generation plant is too large and complex for cargo ship use, then build and install a thorium-fueled Molten-Salt generation plant. They can be both much smaller and more flexible than the light-water plant.
And the technology is currently available.
A fleet of such cargo ships would DOMINATE the world shipping lanes, because per-unit shipping costs would be sharply lower, and speed of transport could be conceivably somewhat quicker, as turnaround at the port is limited only by loading and unloading capabilities - no refueling time for YEARS.
And would be targets of terrorists for decades who wanted to get ahold of nuclear material for dirty bombs. Or just make the cargo ship a dirty bomb and blow the reactor while unloading in Long Beach, CA.
Is this ready for Commercially ready for Prime time?
And is anything with molten sodium in a harsh corrosive marine water environment, a good idea?
(I know it would supposedly be a closed loop system)
