It literally could be replaced by sailing, but would be much more expensive, more human-labor-intensive, and less efficient. But it's entirely technically feasible, especially if motors or tugs are used for harbors and channels.

- hchz 6y agoThe largest bulk carriers would need to be replaced by almost 10,000 of the larger of these ships, and 400,000 of the smallest. There are no commercial ports capable of this transition. It's not technically feasible if it would take years to load and unload.
