We spoke with One Laptop Per Child's former Chief Technology Officer, Mary Lou Jespen, at the first ever Greener Gadgets conference in Manhattan. Jepsen was on-hand to discuss the greener aspects of the organization's newly-introduced XO laptop.

As CTO of OLPC, Jepsen was charged with innovating new, low cost technologies that could be deployed to children in developing nations. As she and her fellow OLPC employees discovered, low cost and green need not be mutually exclusive.
