How much water does a Aircraft carrier need to carry for the 5000 plus sailors? None! Why because they convert sea water to fresh water (this is the same with cruise ships). Too bad California is not next to a large body of water that they could use the same technology for their three largest urban areas (San Diego, Los Angeles and San Francisco).
They put a nuclear power plant next to the ocean, but can’t put a desalination plant next to one.............
