Do these use the least amount of energy possible (lowest CO2) to produce fresh water, OR, are they "advanced" because they take up very little physical space on board BUT burn significantly more fuel to produce water? How many kWhr to produce 1000 liters or fresh water? And how does that compare to best practice desalination? I think we know the answer to those questions, but it's interesting that the cruise lines are trying to give the impression that they are caring for the environment when they say they use "advanced" technology, whereas the technology is actually "advanced" towards a different goal, not towards the environment.
