MIT Media lab has started a project that will put $100 laptops in the hands of children who normally wouldn’t have them in countries where, in some cases, they do not even have electricity.
The students will be able to use the laptops at school and at home. One power solution possibility is a crank generator that will power up the laptop’s battery. The best part of all is that these laptops will run a version of GNU/Linux (http://www.linux.org).
