Harold Haas has an idea.

A very interesting idea.

Harold’s idea is to use an ordinary light bulb (adapted with signaling processing technology) to transmit data.

Think about that for a minute.

You could download films from the lamps in your house.

The computers in your office could connect to the Internet by the overhead lights.

It could benefit industries from deep sea diving to air travel.

Using something that is cheaper and more widely available than the present infrastructure.

The technology that makes this possible is called Visible Light Communication.

I prefer it’s nickname: Li-fi.

The light based alternative to Wi-fi.

A few years from now on the Internet could be just a flick of the lights away.

(Hat tip to Wired)

Here’s Harold demonstrating Li-Fi.
