Thirty years ago, when I was handling PR at the newly-formed Office of Energy Conservation and Solar Energy at the U.S. Department of Energy, we released a TV public service announcement called "Master of the Sun (video)." It featured a Ponca Indian poet high on a Colorado mountain talking with his young son: "Since the beginning, the American Indian has valued the power of the sun," he intones. Against pretty visuals he tells his son what the sun can do for us, then concludes as the music crescendos: "The sun is power. The sun is security. The sun is your future. The sun is available now and forever."
