> If you have access to the sea and to uranium you can make all the freshwater you need
I don't believe that would be true on a large scale because the seaside would quickly become polluted with brine, and then having an infinite supply of uranium wouldn't help you.
Desalination only works in the long term if there is an unlimited amount of body water to dilute the brine produced by the process.
Do you have to release brine directly into the seaside? What about long pipes with holes that go 50-100 kilometers into the sea?
There's no question of polluting all the oceans with brine. They get freshwater from the rain and the salt came from the oceans in the first place. We aren't net destroying water molecules.
