  • 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.
