Thorium poised to meet world's energy needs
...re thorium could not only gradually replace fossil fuels as the world's energy source, but nuclear energy as well." Thorium, which is plentiful in North America, can produce fewer environmental and human health hazards in its fuel production than the conventional uranium fuel cycle.
