Splitting the sea

so 80 million occupied home in US...roughly 80 million gallons of water a day...29 billion two hundred gallons of water a year....that's a lot of water paw paw...I'm not counting stupid electric cars since there are like 50 in the US
may be ok, there is about 643 Quadrillion gallons of water in teh Gulf

My thought was that you could build a plant near the water that could supply to the existing grid. At least use those to offset nuclear as those plants scare the carp out of me.
