Floating cannon battles with the Ron Paul blimp.
The engineers don't have to seem as silly now that they get to put the purestrain gold shells to good use. Hard to starboard!

Um, no it's not. Sorry you suck at reading.
"We need more sensationalist bullshit that doesn't actually reflect the event PRONTO!"
>What's so great about nuclear fusion? If this works does that mean we'll have clean energy without radioactive byproducts?
Yes. Some reactions produce neutrons, but that's more of a 'how do we shield the reactors properly' issue.
>Why is this better than nuclear power plants today?
Because it's several (well, that's an understatement) orders of magnitude more efficient (in theory) and does not require uranium mining. Startup requires an initial energy investment but after this it is self-sustaining.
>Next, assuming we get this working, what material does it require to make it work successfully? And really, what then becomes the bottle neck to producing infinite cheap energy?
Mostly hydrogen and helium isotopes. Since fusion is not a particular, there are several different combinations that can result in exothermic reactions. Helium-3, for example, is known to be present in abundance on the moon. Unfortunately, the kind of reactions that it's involved in kind of suck for various reasons (energy density and production of neutrons) and helium in general is rather difficult to produce anyway.
They testfired the lasers they're going to be using for fusion later. Those beams (attempt to) put out a fixed amount of energy. They reported the total energy. No fusion happened, no energy was net produced, the only thing that happened was the lasers fired at 420J each.
This is pretty clear from the article, but not like anyone would RTFA anyway.
With all the fancy scientists in the world, why can't they just once build a nuclear balm?
