... Mary Lou Jepsen's inventions in connection with the display of the One Laptop Per Child box will turn out to be of enormous importance to the world. The One Laptop Per Child box (which I've spent a lot of time helping with this past year and which everybody in this room ought to be thinking about hard, because it's a great moment in human technological history), the One Laptop Per Child box has a few requirements that are really important for computers in the twenty-first century. One: a child has to be able to take it apart safely. Two: you have to be able to generate electricity for it by pulling a string. Three: it has to be culturally accessible to people who live in a whole lot of different places around the world, speak different languages, have different world views, have different understandings of what a computer is or might be or could be or what this thing is that their children are holding. It has to be discoverable. It has to be a place for a child to explore indefinitely and learn new things in all the time. I just want to concentrate on the first parts: it has to be something you can pull a string to power, and it has to be something a child can take apart safely. No existing LCD panel meets those needs, because every existing LCD panel in the world uses a mercury back-light which runs on high voltage which is dangerous and which contains toxic chemicals (the mercury itself of course). So how about a display which gives you transmissive color " beautiful color " indoors, and high-contrast black and white in full sunlight, so that it can be used in every natural environment, and which consumes per unit area one tenth of the electricity used by standard current LCD panel displays. How about that it doesn't have any harmful substances in it, can be safely disassembled and reassembled by a child down to its components so that field replacement of almost anything can occur, and is in addition cheap to manufacture. So we're going to give an enormous gift to all the cell phone and gadget manufacturers of the world out of OLPC " which is why Quanta, the largest manufacturer of laptops in the world, and the display manufacturers throughout the Pacific Rim are screaming to be first or second sources of the OLPC display. Because the patents in there are worth sharing. In other words, the free world now produces technology whose ability to reorient power in the larger traditional economy is very great. We have magnets; we can move the iron filings around. We can also change the infrastructure of social life. That OLPC has every textbook on earth. That OLPC is a free MIT education. That OLPC is a hand-powered thick-mesh router. When you close the lid as a kid and put it in the shelf at night, the main CPU shuts down " but the 802.11 gear stays running all night long on the last few pulls of the string. And it routes packets all night long and it keeps the mesh. The village is a mesh when the kids have green or purple or orange boxes. And all you need's a downspout somewhere, and the village is on the Net. And when the village is on the Net, everybody in the village is a producer of something: services, knowledge, culture, art, YouTube TV. ... http://www.cpu.uttaruk.com/2007/01/25/eben-moglen-on-free-software-and-social-justice/ -- ________________________________________ http://olpc.ellak.gr/
