Everybody's trying to stay cool this summer, and Honda is resorting to old-school low-tech for its Ohio plant, cooling it with good old-fashioned ice. During off-hours, at night when power is cheaper, they're using two 450-ton chillers to make huge blocks of ice, and then they're using them to cool off the air all day as the ice melts.

Sounds like a great way to store coolness at the lowest cost, and the company says the system will pay for itself in savings over three years. The greenies like it too, because it doesn't use any environmentally unfriendly gases such as freon. Everybody wins. – Charlie White
