No, I can't say I know much about the Thorium fuel cycle, but I think there are, if not miracle technologies, at least good solutions out there, but we need to invest the money and expertise to find them, and the public needs to trust the scientists and engineers who have spent their life studying and designing these things. My personal belief is that as a species, we will either choke ourselves on fossil fuels, or we will adapt to a new energy economy which takes into account carbon in our ecosystem. I just don't think solar, wind, biomass, and hydroelectric are capable of sustaining the energy usage we're accustomed to. I don't know if you've seen the documentary Pandora's Promise, it felt like PR by the nuclear industry, but I do think they have a point with respect to overall environmental impact.
