There are desalinization systems for boats. They are expensive but everything about boats is. I saw one model that produces 20gph and seems to use about 1200 watts.

Doesn't feel like there is a gross thermodynamic reason it wouldn't work.

20 gallons = 75.7 liters.

4 to 6 liters is 5-8% of that.

5-8% of 1200 watts is 60-96 watts.

If you remember the numbers right, that thing is already roughly in this range. A 100 watt solar panel might fold into a briefcase.
