ROFL. Ice-makers work by using heat-pumps. some water gets cold enough to freeze, other water gets hotter. (Works just like your air-conditioner.) Net result is no-change, just a lot of energy wasted in the machinery (which also adds heat to the water). If that system worked, you could cool your house by leaving the fridge door open.
