I have been reading into LFTR nuclear reactors lately and I must say I like what I see. From what I read about it, it can't be made into nuclear weapons, its waste stops being radioactive faster and there is much less of it, it can take conventional nuclear waste and use it as a fuel. It can't explode (which is a big plus) and it can shut itself off in the event of something going wrong. However whenever I mention it as a alternative to conventional nuclear power I always get that its impossible, a failure, will never work, etc. I know that it need more work still, especially for the design of the reactor and turbines but I don't know why there is so much hostility against it.
