Next trick: make it into a paint or spray-on treatment.

Better yet, make a giant sheet of it and float it in the ocean to fix the earth's albedo and stop climate change.

The copepods and algaes also need the light to draw down assloads of carbon though. Those tiny creatures suck up staggering amounts.

Oh, great idea! A nanoparticle ceramic aluminum oxide aerosol? What could possibly go wrong? 🤣

[-] gregorum@lemm.ee 6 points 11 months ago

lol, it doesn’t have to be aerosolized in order for it to be sprayed. It can come out of a spray hose nozzle and be appropriately viscous. Workers can wear PPD.

You're missing the point, and even at that: this reply is insanely short-sighted. Aerosolized or atomized, is still fucking airborne nanoparticle ceramic aluminum oxide. 🙄

I didn’t miss the point. You’re not understanding what I’m describing in a sufficiently contained substance that leaves its container and reaches its target surface with practically zero contamination of the local area. With a sufficiently viscous base liquid, it would be fine.

Maybe a paint that you put on with a hairy stick brush would be better?
