Wireless data transmitted through light bulbs [TED]

Standard

Below is a very interesting TED talk by Harald Haas from July 2011 on the use of light (and light detectors) to transmit digital data. I watched this video in August 2011 and just watched it again from my downloaded archive. This is really interesting.

It is worth noting, as Harald mentions, that data is transmitted as electromagnetic waves. And to those who are not aware light is an electromagnetic wave.

This work is very interesting and will definitely help in the detection of widespread diseases like Tuberculosis (TB) in developing countries. The only primary obstacle that needs a real solution is countering the monopoly by vaccine manufacturers.
