Green machine.


Scientists hope a $100 laptop will let kids all over the world own a computer. The affordable, green laptop, created by scientists at the Massachusetts Institute of Technology Massachusetts Institute of Technology, at Cambridge; coeducational; chartered 1861, opened 1865 in Boston, moved 1916. It has long been recognized as an outstanding technological institute and its Sloan School of Management has notable programs in business,  (MIT MIT - Massachusetts Institute of Technology ), can even be used in places without electricity.

The computer can be powered by winding a bright-yellow hand crank. The kinetic energy kinetic energy: see energy.

Form of energy that an object has by reason of its motion. The kind of motion may be translation (motion along a path from one place to another), rotation about an axis, vibration, or any combination of
 of the cranking motion is converted into electricity. "The hand crank drives a small electric generator that recharges the laptop's battery," explains Michael Bove of MIT's Media Lab. One minute of cranking delivers enough energy to run the computer for 10 minutes.

The laptop also uses less energy than other computers. For instance, it stores information on flash memory instead of the hard disks used in most computers. Flash memory, also used in digital cameras, has no moving parts Moving parts are the components of a device that undergo continuous or frequent motion, most commonly rotation. "Parts" only include the mechanical components which does not include fuel, or any other gas or liquid.  and runs on less electricity than hard disks. Within a year, MIT plans to produce millions of the machines.
