  So where does the waste heat go?? That ice-making would violate the Law of Conservation of Energy. If you take heat-energy away from some water to make ice, you have all that heat-energy to put somewhere. Where exactly? And, seeing that ice-making itself is not 100% efficient, the overall operation would melt more ice than it makes. The whole idea smacks of cooling your house by leaving the fridge door open.

    I guess waste heat stays but by increasing future albido more sunlight is reflected having cooling effect same as ice caps. Again I guess, it would operate in polar circle where water is significantly cooler, and convert solar energy to create ice, and re-use heat to additionally power maybe sterling engine, converting it further to mechanical energy? Question that need answers are: - what would be the amount of reflected light? - how many of these in theory we would need to have any impact? - what is operational cost? - how much energy they need? - dump heat does not need to be huge, salt prevents freezing, so temperature to freeze in salty water is -2C (28.4) and fresh water 0C (32F), so just by removing salt in some areas would create ice ... still it would be good to have calculation
