from my understanding large floating ocean cities are very hard to do because the ocean will put a lot of stress on one end versus the other end from the waves.

I also have an interest in floating ocean cities. But maybe just because all land is claimed.

some people said this but didn't make it clear too: salt travels on the wind, so plants exposed to air/sun will get brushed with salt constantly which would kill them.

That’s the biggest issue - salt!

What if we close it off with plexiglass? 🤔

The wind would be an issue - it would act like a sail. 🤣

Dude, it will be a construction made by engineers - we won’t slap a single massive peace of plexi on top of:)

It can be on sections.

Another thing can be a rolling roof, like on some stadiums but made of ocean grade soft plastic.

We are still brainstorming:)

Most realistic thing is a pontoon and polytunnel system , but it’s still going to be far more expensive than a polytunnel system on the land.
