All Around Cooler

Sierra College (Calif.) installed CALMAC IceBank thermal energy storage tanks to help control energy costs. The tanks create ice overnight when energy in the state is generated using natural gas, and the ice is then used for cooling during the day. The three tanks on campus save from $5,000 to $10,000 per month, and the tanks are used as a canvas by student artists.
