The current creates hydrogen by passing through acidic water. The new PV cell may have made hydrogen commercially competitive, even before natural gas prices rose. The hydrogen economy, with the hydrogen provided by various types of solar technologies, can liberate the planet both from production of more radioactive poisons by nuke-plants and from the greenhouse gases and other pollutants produced by fossil fuels. The USA could commit itself to the hydrogen economy now , for the sake of health, the environment, national security, and abolition of wars over oil. The fuel of responsible civilizations will be renewable solar-generated hydrogen gas.
Radioactive atoms emit ionizing radiation as they decay.
In any case, sudden catastrophic releases are a threat limited to a few decades of operation. The real problem endures for over 1,000 years. Permission to operate a few additional nuke-plants might appear like a minor issue. Ethics aside, it is clear that nuke-plants were not necessary in the past, and will not be necessary in the future. Gifts are tax-deductible.
