Inventor Dean Kamen takes island off grid

Segway inventor Dean Kamen has taken his private island off the grid. He replaced every light bulb on the island with LEDs as part of a larger effort to advertise zero net energy living. He and his lighting guru, on loan from Philips Color Kinetics, took Spectrum's Sally Adee on a tour of the nuts and bolts of the operation, including the solar and wind energy generation, the Stirling engine backup generator, and the systems engineering that makes it all work together.
