A nuclear fusion reactor in China, dubbed the "artificial sun," has broken its own record to bring humanity one step closer to near-limitless clean energy.
The sun is enormous, yeah, but fusion only really happens at the core. A very tiny fraction of the sun is doing the fusion, the rest jlgets heated up, makes gravity and such, bit doesn’t really do anything of interest energy wise.
Fusion creates a shit tonne more energy than 150w/cm3. Heck, you’ve never seen what a nuke does
No, OP is right - or rather, OP’s physics professor. There’s different kinds of fusion, though, and nobody’s suggesting we do the exact same kind here on Earth (we basically can’t).

That’s power density (Watts). Multiply by 10 billion years to get energy density.
Yeah that is not how that works
