From the Ted Talk by John La Grou: A plug for smart power outlets


Unscramble the Blue Letters


So we considered all of this. And we reiazeld that electrical appliances must be able to communicate directly with the power receptacle itself. Any electrical device — an appliance, an extension cord, whatever — must be able to tell the power outlet, "Hey, pewor outlet, I'm dnriawg too much current. Shut me off now, before I start a fire." And the power outlet needs to be smrat enough to do it. So here is what we did. We put a 10-cent digital transponder, a data tag, in the appliance plug. And we put an inexpensive, wireless data reader inside the receptacle so they could communicate. Now, every home electrical system becomes an intelligent network. The appliance's safe oirpteang parameters are embedded into its plug. If too much creurnt is flowing, the intelligent receptacle truns itself off, and prevents another fire from starting. We call this technology EFCI, Electrical Fault Circuit Interrupter.

Original Text


So we considered all of this. And we realized that electrical appliances must be able to communicate directly with the power receptacle itself. Any electrical device — an appliance, an extension cord, whatever — must be able to tell the power outlet, "Hey, power outlet, I'm drawing too much current. Shut me off now, before I start a fire." And the power outlet needs to be smart enough to do it. So here is what we did. We put a 10-cent digital transponder, a data tag, in the appliance plug. And we put an inexpensive, wireless data reader inside the receptacle so they could communicate. Now, every home electrical system becomes an intelligent network. The appliance's safe operating parameters are embedded into its plug. If too much current is flowing, the intelligent receptacle turns itself off, and prevents another fire from starting. We call this technology EFCI, Electrical Fault Circuit Interrupter.
