Physician Gale may be an expert in cancer treatment, but as a layman on alternative energy, he should get his facts straight. Photovoltaics has been used reliably since the late 1950s for space power, and since the 1970s it has become a viable, pollution-free, quiet alternative energy source that uses only sunlight as fuel. Present and future technologies do not cause a loss in lives nor do they produce toxic wastes. Such solid waste as sodium silicate that results from the chemical etching of silicon is as inert as beach sand and does not represent "toxic waste that is comparable or greater in magnitude as nuclear energy."
