We chat with Matt Rogers of Nest at CES 2012 in this episode. Nest is a learning thermostat that is created by the guys who created 13 generations of iPod and a few generations of the iPhone, and is an ingenious way to re-imagine saving energy in your home. The thermostat is a round metal dial with a circular color LCD screen that works a lot like an iPod classic click wheel. You can turn the temperature up or down by twisting the dial, or you can go through its menus by pressing it in like a button. It can be set to automatically change the temperature based on the time and whether you're present. We also demo the Nest thermostat to show you exactly how it all works.
