The sediment that gets pushed out into the surrounding water. That gets pulled up with the ball as it creates negative pressure behind it as it rises.
Bro, the ocean is FILTHY. Like, crazy filled with stuff. Like, you could take a coffee filter and pull stuff out filthy. Like the water has so many living organisms in itself it’s basically alive.
And let’s talk about the salt. Corrosive af salt.
This isn’t impossible, but the people trying to point out why this is CRAZY difficult are right. This will not be a set it and forget it scenario by far. It will need regular maintenance. The issue is whether that maintenance is easier or harder than a dam or stationary tank.
Like, why can’t we build these in giant freshwater reservoirs? Stick them a pool. Or why does it need to float? Wouldn’t a tank at the bottom of a pool with a pump do the same thing? Or two tanks at different heights with a conection between them and a pump? This is just mechanical energy being stored for later. Do the work when it’s cheap and reclaim it later.
