There's a lot of skepticism going on. I too don't see it working either, although I lack the knowledge to judge.

From what I've read so far it certainly does require power and doesn't jumpstart itself. Question is how much power does it need, and how much is it able to generate. Maybe not their simple experiment one, but an industrially optimized one.

Still looks like sth that has already been tried and the math just doesn't work, yet it's remarkable that these young girls are working on these problems. It shows what education can do and impressed me nontheless.
