Wireless data from every light bulb Harald Haas on TED.com

What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas demonstrates, for the first time, a device that could do exactly that. By flickering the light from a single LED, a change too quick to for the human eye to detect, he can transmit far more data than a cellular tower — and do it in a way that’s more efficient, secure and widespread. (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland. Duration: 12:52.)
