isn't this a way they make a bomb?

For fusion to occur, the hydrogen but be compressed at high temperature. If the hydrogen are slowed down to a metallic state, there is not energy for fusion to occur.

Maybe metallic hydrogen would allow for smaller H-bombs but that metal would still have to be energized at high temp.

The internet said so.

has potential as (chemical) rocket fuel

The brother has such a nice first-principles experiment, he should load it up with some deuterium and look for fusion byproducts. I know, I know, but would it kill him to do this? ( if it works, perhaps! )

All the talk of superconducting power lines makes me wonder what would happen if they got hit by lightning?

There is some pretty vocal opposition to the idea that the group has actually done this. I don't know enough about this field to make a judgement based on the experiment, but the it sure sounds like this team's observations could be spurious.

The paper's on arxiv, here.

It hasn't been reproduced, even by the original researchers. The original sample is still under pressure though, so experiments can be done. Some kind of phase change happened to get that last pic and nobody seems to be doubting the precursor black phase. The part that may not be appreciated is that the diamonds often break and it's entirely likely the next time they use the press they'll break it. So you can see the dilemma. Getting everyone's attention and input at this point was probably a good idea, even if it looks a little self serving.

The critics seem pretty skeptical in the Nature News piece:
