Now I can't remember where I saw the piece on photovoltaics on the Navajo reservation. It may have been in some of the business press. It still costs over $20,000 to install a mile of electric line and there are still thousands of people using gasoline generators or having no electricity at all. This project builds a summer shade and installs solar cells on the roof that generate enough power to run a small TV, a small refrigerator, electric lighting, and a few other very useful items to have. The piece had several photographs and it could be seen that turquose-colored vehicles are still the favorite. Now I think that the piece was in Metropolis, but I can't find it.
