Dean Kamen always seems to be one or two steps ahead of the rest of us. He invented a wheelchair that climbs stairs, the Segway scooter, and a robotic prosthetic arm that moves based on thought, among other things.
Mr. Kamen also owns North Dumpling Island, a three-acre island off the Connecticut coast that he jokingly refers to as an independent nation. But now, it's more than that - he calls it "the world's first LED nation."
