What if every light bulb in the world could also transmit data? At TEDGlobal, Harald Haas showcased, 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.

The application capabilities in a closed environment (airplane, airports, home, car...etc) exist, vs large scale data communication, are limitless. This is Brilliant!
