SmartSwitch FEB 23 2009
The SmartSwitch is a replacement for a standard light switch that becomes more difficult to turn on when power usage is high in the household or on the grid as a whole.
Equipped with a network connection and a brake pad, the switch provides its user with tactile feedback about the amount of energy being used either within their household or by the electrical grid as a whole. SmartSwitch doesn't restrict the user from turning on a light, but rather it passively encourages behavior change. SmartSwitches can be programmed to respond to either personal or communal electrical usage. In a home wired with SmartSwitches, lights can become harder to turn on during hours of peak demand. The switches can also be customized to reflect household-specific energy conservation goals.
That is really clever. I want the same thing for my computer...e.g. it's more difficult to type when I shouldn't be using it. (via o'reilly)
