    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).

    Fusion creates a shit tonne more energy than 150w/cm3. Heck, you’ve never seen what a nuke does

    That’s power density (Watts). Multiply by 10 billion years to get energy density.
