MIT's $100 crank-operated laptop

For a long time, MIT has been developing a low-price laptop computer for use by children in primary and secondary education around the world, particularly in developing countries. The laptops should start appearing in volume in late 2006.

The 500MHz laptop will run a "skinny version" of the open-source Linux operating system. It will have a two-mode screen, so it can be viewed in color and then by pushing a button or activating software switch to a black-and-white display, which can be viewed in bright sunlight at four times normal resolution, according to Negroponte. He estimates the display will cost around $35.

The laptop can be powered either with an AC adapter or via a wind-up crank, which is stored in the housing of the laptop where the hinge is located. The laptops will have a 10 to 1 crank rate, so that a child will crank the handle for one minute to get 10 minutes of power and use. When closed, the hinge forms a handle and the AC cord can function as a carrying strap, according to Negroponte. The laptops will be ruggedized and probably made of rubber, he said. They will have four USB (Universal Serial Bus) ports, be Wi-Fi- and cell phone enabled and come with 1G byte of memory.
