Tangentially related side note, as a plasma physicist, every time I see advances like this, I worry a little bit for my future career[0]. It turns out there's a fusion reactor at the center of this solar system that's been dumping energy on us for billions of years. Of course, eventually all energy sources on earth were solar originally.

Not that doing fusion won't be interesting from a scientific point of view, but if we develop solar and batteries further, we could really require no other energy revolution than this.

[0] tongue-in-cheek, there's always stuff to research.
