It's also theoretically possible to have a "warp" drive that produced thrust without propellent by altering the local spacetime metric.
Err not really. You have to violate a bunch of things widely held to be true for real mass configurations. Also you need negative mass, which doesn't exist even theoretically, oh and more mass energy than the entire universe. Finally it is totally causally disconnected from the rest of the universe.
Just because i write down math does not make it a valid prediction.
Thorium is nice because it's only minimally radioactive, can be stored in huge piles without getting 'hot', and won't sustain a reaction without encouragement - hence throttling ability.
The same is true for Uranium. Since a Thorium fuel cycle *burns* 233U it also still has decay heat. Throttling down can be done, but heat dumps are required. Not hard to do since even conventional generation often needs that. Thorium is not magic and homogenous reactors not restricted to Th.
Why are some people so eager to throw out established science, when it's far, far, FAR more likely that it's an experimental error or miscalculation?
Because it is not global warming
