threats to u?

Just wondering if anyone had some educated opinions on threats to uranium demand

The way I see it, based on available proven technology, Uranium is the only viable solution to the energy crisis (if you believe in global warming), and if there were no other technologies in the pipeline I'd put my house on the stuff.

BUT, my only doubt on Uranium for the long term is that another zero carbon solution could blow nuclear reactors out of the water?(pardon the pun)

I'm talking about things like thorium reactors, the technology terrapower (bill gates and his friends) are working on, and the hydrogen technology China are said to be working on.

Does anyone see any of these technologies coming to fruition in the next 5 - 10 years?
