Any altitude of orbit can become space debris. They just won’t stay space debris for nearly as long as geosynchronous or high orbit.

Have you got a nice big valley with an existing water flow to donate or sell to a new hydro plant?

Hydro is absolutely great (if you ignore local ecosystem ecological damage) but it has very significant land use requirements. These can make it difficult to build practically once you have most of the good spots filled in, so it’s incredibly difficult to price new builds of it. Some areas may be infinite cost because the land topology simply doesn’t exist. Others may have the perfect site and be relatively cheap.

I literally don’t even install it on Linux because the screen share works more often through Firefox than through their native app. That doesn’t mean it works consistently, and there’s never any sound, but at least I can sometimes make it work in the Firefox webapp. The native app is worthless.
