LAS VEGAS –
For the past 40 years, the Consumer Electronics Show
has served as a mecca for the latest technological marvels geared to
the tastes of affluent first-worlders.
But at this year's show, one new device aims to suit
some of the world's poorest consumers. The One Laptop Per Child (OLPC)
Initiative unveiled its final industrial prototype of the XO - a laptop
computer with a toylike look. But to say it's a toy is misleading. The
device is intended to bring the most isolated tribal village into the
Information Age, with the ultimate goal of offering one to every child
on the planet.
The XO is designed to survive and thrive in a rugged,
power-sparse environment. Whereas a typical modern laptop requires 40
watts of power to use, this power miser needs a meager three watts to
browse the Web, and less than a single watt to display an electronic
book.
The reason for the emphasis on low-power usage becomes
clear when you realize that the power supply for the computer is human.
The XO is equipped with a yo-yo-like generator that can be pulled with
either a hand or a foot. By keeping power consumption low, the XO can
offer between two and five minutes of computing for every minute spent
generating power.
"Power was obviously our main concern," said Michalis
Bletsas, OLPC's chief connectivity officer, at Monday's unveiling in a
small ballroom at the Bellagio Hotel.
But that didn't prevent the designers from making the
laptop as powerful as they could manage. The computer includes an
innovative "mesh" networking technology that automatically connects
every child in a village to each other, as well as to any Internet
connection that might be available, as in the case of a satellite link
or cellular connection. The mesh can link XOs up to 600 meters
(one-third of a mile) apart.
The XO's innovative screen can operate in either color
or black and white. In black-and-white mode, it can be viewed clearly
even in the brightest sunlight, ideal for rural villages where many
activities occur outside. The laptop also has a video camera and
built-in speakers.
The XO runs a trimmed-down version of the open-source
Linux operating system. According to Mr. Bletsas, both Microsoft and
Apple offered versions of their operating systems for the project, but
neither was compact or secure enough to meet OLPC's needs.
The goal price is less than $100 per unit, which the
initiative hopes to achieve by 2008. "Currently, we're closer to 100
euros [USD $130] per laptop," Bletsas says.
By keeping the price low, the OLPC initiative hopes
that governments in the developing world will be able to afford them.
Already, Argentina, Brazil, Libya, Nigeria, Pakistan, Thailand,
Uruguay, and, most recently, Rwanda have committed to participate in
the program. Rwanda hopes to have laptops for all of its schoolchildren
within five years.
OLPC expects to start delivering the machines this summer, with the goal of delivering 5 million units the first year.
