Using Visible Light for Data Transfer

Posted by chrisd on from the look-at-the-pretty-lights dept.

James Evans writes "Wired has an article about a New Zealand company which has developed a technology to transmit data at speeds up to 400Mbps up to 4km. They are working to have it more resistant to changes in weather, as well as increasing the distance. It has a number of advantages, including lack of federal regulation of the spectrum, as it is of course, visible light." In related terrestrial networking news, waytoomuchcoffee writes "Science Blog reports that the backbone for the World's Fastest Network is up and running. It's a fiber optic 40 gigabit per second connection between Chicago and LA. Teragrid is a project by the National Science Foundation designed to link up supercomputer centers."

    "What kind of peace do I mean? What kind of peace do we seek? Not a Pax Americana enforced on the world by American weapons of war. Not the peace of the grave or the security of the slave. I am talking about genuine peace, the kind of peace that makes life on earth worth living, the kind that enables men and nations to grow and to hope and to build a better life for their children--not merely peace for Americans but peace for all men and women, not merely peace in our time but peace for all time."

    I have wanted to beat my old roommate about the head and neck for his refusal to flash vehicles at night that didn't have their lights on. His reasoning? He was told in a drivers education course that this was illegal. I promised that I would pay him double whatever the ticket was if he EVER got fined signaling someone to turn on their lights at night.

    I've tried looking for this law (I'm in Florida) but I haven't found anything about it. Do you have any info?
