The reality:
In Pueblo, that device would be about as effective as a Band-Aid on cancer. The trick is to reduce the temperature of the water collector below the dew point. The higher the dew point, the easier the job. In Connecticut, you'd go to a shoplifting mall in the summertime, and see pools of water beneath all of the cars, caused by dripping from their air-conditioning systems. In fact, the major job of an AC thereabouts is to wring water out of the air. 80-degree air can feel cool if there is a breeze and the air is dry. If the humidity is very high and the air is still, 80-degree air can feel very stuffy.
The discharge temperature of a typical AC is about 40 degrees. If the dew point is higher than that, water will condense on the coils. If the dew point is 25 degrees, then you can condense water, but it will freeze instead of dripping. (Sometimes this will happen in the car's AC on long drives, and the cure is to turn off the AC but keep the fan running to get rid of the ice.) In any case, the colder you have to get the evaporator, the less efficient the system becomes at producing water from the air.
The gadget does have some merit, but in most cases, the very same effect can be had by using the electricity produce by the wind turbine to run a dehumidifier.
