IAS, it's the licensing of patents back from China that bothers me. They are very good at taking things upmarket. They may license certain technologies until than have a manufacturing base (or are shown that one is profitable) after which they will no longer sell licenses without a purchase of physical products. If that continues, they will only sell complete systems. I've seen it happen in many industry's and it's a good move on their part, but sucks for the rest of us.
Germany never had a renewables industry. The feed-in tariffs have made the whole thing an economic sham. Did they sign the Kyoto agreement? I wonder how they are going to hold up their end while replacing their nuclear reactors with coal plants if they did.
LFTR may have failed in its seed in the US since it doesn't produce weapons grade nuclear material and at the time it was being developed, that's what politicians wanted, lots of bombs to protect the country from the USSR.
