Jim Green, national nuclear campaigner with Friends of Earth, writes: Re. "Climate debate: solar power is just a 'toy'" and "The Power Index: carbon cutters, Martin Green at #8" (Friday). In the comments section, Geoff Russell opines that China is "gearing up to produce small modular reactors by 2020 or thereabouts". This is the standard "look over there" tactic of the nuclear zealots. What is actually happening in China, as Russell well knows, is that dozens of '"generation 2" reactors are under construction or in planning -- reactor technology that wouldn't be licensed in the West.
