I still haven’t heard any arguments explaining why thorium power plants wouldn’t work. As an energy source, the advantages are clear, with very little downside, so I’m not sure why this isn’t a bigger part of the national discussion about the future of energy. Cynically, I’m not sure people want actual solutions to the energy problem. Why come up with actual solutions when its easier and more lucrative to play politics. Just look at Solyndra. And there is still a lot of money to be made by the established interests in existing energy sources. Plus, existing nuclear technology was developed for the express purpose of making bombs. You can’t do that with thorium.
Realistically, the high initial cost, long ROI, unproven technology, and regulatory barriers probably make building a plant anytime soon a non-starter. This TEDx talk is a good primer on thorium power plants:
