 NEW YORK (AP) - As the summer swelters on, skyscrapers and apartments around the city will be cranking up the air conditioning and pushing the city's power grid to the limit.
But some office towers and buildings have found a way to stay cool while keeping the AC to a minimum — by using an energy-saving system that relies on blocks of ice to pump chilly air through buildings.
The systems save companies money and reduce strain on the electrical grid in New York, where the city consumes more power on hot summer days than the entire nation of Chile.
