First Laptop With Full-Sized Solar Panels Will Run On Ubuntu 155
iwritethings writes "The Sol, a rugged-looking laptop with built-in foldable solar panels is designed for use in the military, education and developing countries where electricity is scarce. The Canada-based makers behind the Sol claim that the device can run directly off solar energy or can harness the sun's rays to charge the laptop's battery in under two hours. Once fully charged, the battery is expected to last between eight and 10 hours. While the concept of solar charging gadgets isn't new, this type of battery life is unprecedented. There's no word on when Sol will launch, but its headed to Ghana first, and it will run Ubuntu Linux."

Moreover the thing looks very fragile, like the panels could snap off with the slightest misuse, such as in a combat situation.
