Just the sound of the ocean for those in Calif. I've read some articles on wind generation and its is not the solve all but it seems that if enough different types alternative power were used it might have some impact. Remember back in the 70's( ?) when solar for homes was the ticket? It never really caught on, although it isteresting that they are now looking at that type of energy again in Calif., using the roofs of all the major buildings to generate power. This is totally off the subject of cars, I guess I need to shut up. Have a great week.
