Does anyone have information on the water-consumption (steam-loss, cleaning the mirrors, cooling the mirrors, and so on)? I would really love to see, if this is a feasible method of producing energy in areas without that much water. But I really lack the necessary numbers in terms of consumption of water, to built an idea, if this is a viable technology for deserts and other dry and sunny places on this planet.
