Nest is primarily a system that lets people save energy (and money) in a user-friendly manner. Which links to an idea that some friends at AE turned us on to — and it's a good one: Clean tech, until recently considered an unprofitable pet project, is making real money. Nest, after all, is a manufacturer of prettified yet humble home devices like thermostats and smoke detectors. But are they really that far off from what Tesla's doing to cars, which hadn't been made with genuine sex appeal in years? Both companies are doing for the energy industry what Apple did to computers and what HBO did to television; that is, making something people crave.
The Nest Thermostat is built around an operating system that allows interaction with the thermostat via spinning and clicking of its control wheel, which brings up option menus for switching from heating to cooling, access to device settings, energy history, and scheduling. Users can control Nest without a touch screen or other input device. As the thermostat is connected to the Internet, the company can push updates to fix bugs, improve performance and add additional features. For updates to occur automatically, the thermostat must be connected to Wi‑Fi and the battery must have at least a 3.7V charge to give enough power to complete the download and installation of the update
