OK ... reducing the cost of transporting oil is still a good thing, and not all tankers carry oil anyway.

I’m not saying this is good or useful invention; but IF it is a good or useful invention it would be good for any cargo vessel to which it can be adapted. Even a tanker full of ship fuel.

Understood. I just wondered why the headline said "cargo ships" but the artist renditions weren't "cargo ships."

If the technology is suitable only to tankers and dry bulk carriers, that's fine too. Maybe the headline writers didn't know the difference, or maybe they thought the simplification of "cargo ships" was sufficient for a technology article for a general audience who (like me) doesn't know one class of ship from another (except for tankers and cruise ships).

Still, I will always be on the lookout for misleading headlines that are not backed up by the body of the article.
