Cargo ships cost $100 million or thereabout, and operate for at least 30 years. Estimating that about 1/3'rd of that is time where these would be useful, this would save about $27 million and the savings grow with inflation, so that's no small change.

> savings grow with inflation

Wat?

If you're saving a $1 in fuel today, then in ten years doing the same thing you'll save more than $1 because fuel will cost more.

I'm not sure it's a useful characterization, since inflation affects everything, but it's not wrong.
