The first units are scheduled to ship in December this year or January next year at an estimated cost of $135 per unit. Technological advances are expected to bring down costs to $100 by 2008 and $50 by 2010, Negroponte told delegates.
It hopes to ship five to 10 million units in 2007 to Argentina, Brazil, China, Egypt, India, Nigeria and Thailand.
The project was kicked off in January 2005. Although the technology is the most visible aspect, the project is not about creating low-cost hardware, according to Negroponte.
"The $100 laptop is an education project, not a laptop project. The motivation is to eliminate poverty," he said.
Scale is key to getting a low cost laptop, he claimed, because it creates a market for the low end hardware that is needed for the project.
New light-guiding nanoscale device can control and monitor a nanoparticle trapped in a laser beam with high sensitivity
Optical traps are scientific instruments in which a focused laser beam is used to exert an attractive or repulsive force on a microscopic object to hold it in place
Scientists estimate that the exoplanet has already lost up to 35 per cent of its mass over its lifetime
The observations were made using the Atacama Array in the Chilean desert
J1043+2408 was observed for more than 10 years, and its radio light curve exhibited a periodic signal repeating in about 563 days
