Does the Great Pacific Garbage Patch count?

Ha! I'm planning to collect the GPGP and turn it into a large artificial floating structure. Floating in the air. https://en.wikipedia.org/wiki/Cloud_Nine_(sphere)

(It's mostly a stunt to show humanity that we can do great things.)

A great Stack Exchange answer on the feasibility of such a structure.

I just skimmed it. Folks are having fun. :) The question isn't what material to use, it's how big do you have to be (with a given material) to float? You can always just make your sphere bigger, eh? (That's kinda the point. It would actually be really really inconvenient to live in a Cloud Nine, no?)

Anyway, I'm also going to use kites. (E.g. Imagine the Cloud Nine with a skirt like the Rings of Saturn, rotating, with the individual "cells" of the kite membrane modulated to afford directional control... Or Magnus Effect "cilia" that manipulate the envelope of air around the sphere...)

The UK is in the Atlantic ocean not in the Pacific.

Saudi Arabia is working on that super-expensive and fancy "The Line" city project.

Which is, frankly, an idiotic waste of money.

Insufficient belief in the afterlife. Today's billionaires are content to burn out in a streak across the sky.
