Yes, but nothing says you can't use that energy again.What the system does is boil the water (X energy per unit mass), pressurize the vapor (raises boiling point) with additional energy cost of about 0.02XThen since that water will condense at a temperature above the boiling point of unpressurized water, transfers the heat to new incoming water, of which about 0.97X gets transferred. So voila, 20x as much water as just straight heat and let it cool.No magic, just a system engineering viewpoint that energy costs more than complexity.
Sounds like the only problem is startup energy cost. Which you might be able to assist by say, preheating it by other means if it's available. Not worth dealing with for mass production, just thinking specific circumstances. Also, it doesn't include pumps for getting the water to and from the source. Obviously, that will be situational dependent. But I wonder what the numbers will be like under various circumstances.
Somebody put Kamen and crew on making a Mr Fusion as the ideal integrated power supply for it. With really dirty water, the waste can feed straight into the reactor, and then you get clean water and enough power to run your time machine.
