Invention and Innovation - What's Behind a Good Idea?

The US patent office is filled with a seemingly endless array of well-intentioned but ultimately ridiculous ideas for devices meant to make life better. Dog ear-warmers? Protective glasses for chickens? How do you separate a great idea from the rest? What turns an invention to an innovation? This documentary follows modern inventor Dean Kamen as he applies the ingenuity that created the Segway, the mobile dialysis machine, and the iBot, into new territory and new ideas.
