Image yourself as 21-year-old Australian Joel Stanley, who not only snagged a coveted Google Summer of Code (GSoC) spot, he is spending his internship at One Laptop Per Child's Cambridge headquarters developing "gang charger" power systems for the XO-1 laptop.
While he's lucky to be designing one of the OLPC Products, the gang charger units will recharge multiple XO laptops at one time via grid, solar, or other power source, I don't think that's the coolest part of his day.
