Harald Haas: Wireless data from every light bulb

This quick TED talk entry is courtesy of 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 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.
