In my opinion, when many people in the USA think of solar they either have no opinion, think of the sun, or think of Pres. Carter's energy saving initiatives. I think with all the technological advances, with all the products available, and with the energy problems in California, people are prepared to think differently about solar etc. They are just trying to do their morning entertainment. Perhaps a feature in the show could be just showing the variety of energy saving devices that are out there.
