Turning one cubic meter of water into steam requires about 10 kilowatt hours of energy (about 250 gallons). Using reverse osmosis cuts that down to about 4 kwhr.
This new method, actually more of a refinement because I used the same concept at the cleanroom I worked at to make DI water, an ionization process that uses electric fields to separate salt from water.
In this case, the energy required goes down to 1.5 kwhr per cubic meter of seawater.
For that 250 million gallon number, it would need a power plant running about 175 megawatts continuously to get that much water in a year. That would generate about 700,000 gallons per day.

So to get 250 million gallons would require about 1.5 gigawatt hours of energy as opposed to 4 gigawatt hours for reverse osmosis and 10 gigawatt hours for steam.
That would take a powerplant of about 175 megawatts 24/7 and would generate about 600,000 gallons a day of fresh water. So if a nuclear power plant running 2 gigawatts were used you could generate over 6 million gallons a day.
