Submission + - Ice Block Air Conditioning (yahoo.com)

JumperCable writes: The AP has an interesting article on the use of ice blocks as air conditioning in New York high rises. The concept is pretty basic. Overnight during off peak energy pricing hours & during the coolest part of the 24 hour day, the system freezes water in storage tanks into giant blocks of ice. These storage tanks are located in the basement (coolest location). They are frozen with ethylene glycol.

Given that most of the brown outs occur during the summer months due to high electric demand for air conditioning, I wonder how much of an effect this system would have in reducing brownouts if it's use was more wide spread. The article mentions it is only cost efficient for large companies. But how much of this is profit padding? Couldn't a smaller system be worked out for home use? CALMAC is one of the producers of these systems.
