ASCE (American Society opf Civil Engineering) has an annual Concrete Canoe Competition. (https://www.asce.org/communities/student-members/conferences...)

You could do that today for cargodrone boats sintering or epoxy glueing beachsand?

Anyway, regardless of that nitpick, it was an interesting read.
