Use ice to power air conditioner! Yes, it can amazingly cut down on the power required for air conditioning by atleast 30 percent. Ice Energy has innovatively developed an energy-efficient energy-storage system that uses a tank of water for cutting down on the required power.
Ice Bear units of the company are an adjunct to standard centralized air-conditioning units. They are roughly the size and shape of a squat refrigerator. Unlike other units that run AC compressors during the hottest time of the day, the Ice Bear cools water during the night and turn it into ice! And this formed ice in turn, cools the refrigerant as it passes through the tank during the day. Hence, it lowers the inside temperature effectively.
