Peter Russo and Brendan Wypich have found a way to combine the Ambient Orb, the EcoPedal, and the competitive utility bill into one amazing nudge. As second year master’s students in the Stanford Design Program, the two have designed what they are calling a SmartSwitch, which lets people know how much energy they are using, not through colors, but through tactile feedback. It was recently named a semi-finalist in the Greener Gadgets Design Competition. We asked the two to describe their technology in a guest post for the Nudge blog.
