The technology is not new. The system creates ice under the power plant which then is used to cool air circulating in the building. According to Honda, the system uses less electricity and water than prior systems. Interestingly, such systems are costly to set up and usually used by convention centers and similar large complexes. Though Honda won't reveal how much it paid, a senior engineer stated the system will pay itself off with three years.
