| Getting Wireless Videos From A Light Bulb Apparently, you can stream videos through a light bulb lol
Soon, getting an ultra-fast LAN bandwidth connection will be as simple as placing your laptop under a lampshade. Fraunhofer Institute is the latest research organization to bring visible light communications one step closer to commercialization.

It would be weird though to have your laptop connected to a lamp or something. But I'm interested how this can develop into something bigger. |

Solution to Bandwidth Scarcity?
With worldwide annual Internet traffic reaching 667 exabytes (that’s 667 quintillion bytes), radio bandwidth is increasingly becoming scarce. One possible solution is to use the abundant spectrum of light which is also an electromagnetic wave. The size of light spectrum is 10,000 more than radio waves’. Moreover, artificial light sources are available almost anywhere, making this new breed of optical Internet viable for mass consumption.
There is no spectrum scarcity for ten foot distance communications. Mass consumption? Only if you live a one room city apartment. |

My local supermarket has solar powered price tags. Not big sun solar - but like a calculator, they work under indoor lighting.
They are normal shelf price label sized devices but have a little solar panel inside them.
They get the price updates via the flourescent lighting above, and display it on the lcd screen.
Slightly smarter than a calculator. |
