One Laptop Per Child's XO 3.0

Non-profit organization One Laptop per Child (OLPC) manufactures inexpensive laptops to help children in developing countries gain access to new technologies. But at this year’s CES, it previewed its new XO 3.0 notebook, which lends the environment a helping hand as well.

The XO 3.0 is a low-power "ruggedized" laptop that can run on solar power. With the use of a solar panel soft cover, the device powers itself on the sun’s natural energy rather than a battery.

It can also be charged via a manual hand crank. OLPC CTO Ed McNierney told Engadget in January that one minute of crank time yields 10 minutes of usage.
