The Nest is the iPod of thermostats. A simple loop of brushed stainless steel encases a chassis of reflective polymer, which encircles a crisp color digital display. Artificial intelligence figures out when to turn down the heat and when to jack up the air conditioning, so that you donít waste money and perturb the ozone when no one is home, or when youíre asleep upstairs. You can communicate with the Nest from your smartphone, tablet or web browser.
Fadell promises the Nest will pay for itself within a year or two of use, and ultimately save you up to 30 percent of your utility bill. And its presence on your wall will be less an artifact of the industrial age than a piece of high-tech art. http://www.wired.com/gadgetlab/2011/10/nest_thermostat/
