Have you heard about this thing?
It’s not made by Apple, but it might as well have, as the founder of the company is Tony Fadell, the one-time Senior Vice Preside of the iPod Divison at Apple. It’s a continually-self-programming thermostat that will, given just a few weeks, learn your habits and preferences and keep your environment comfortable while saving as much energy as possible.
It’s also $249, which is pretty expensive for a thermostat, and it’s unlikely that I’d recoup that much in energy savings. All the same, using less electricity is an admirable goal, wouldn’t you say?
