outofthegrey saidI think that the issue now (post-Fukushima) is convincing people that nuclear is a viable alternative.
Thorium technology is cleaner than the old U/Pu technology, but no one has yet to put money on the table to build a full-sized plant capable of powering an entire city.
Yeah - was just reading that Lightbridge - the company in the US that is working with the Russians to develop some of the technology does not expect commercialization until 2020. There are other plants I think like Norway's Aker. I don't expect these plants to pop up overnight either... especially considering how long it takes to even build a conventional nuclear plant - and I'm sure you're aware it's been decades since the last one was built.
[Also in response to another post above - this video is much shorter than the sorensen vid - and it's a 10 minute remix]
