Scale.

Fusion is easy. It was first achieved in a lab in 1932 with a particle accelerator. Now it's done with fingernail size devices or for high school science projects.

Net energy fusion is straightforward. It was first achieved, triggered by a fission bomb, in 1952. Now it's the primary underlying consideration of politics and warfare.

When you try to bring it down to the power plant level, and keep net energy production, you're fighting the scaling factors of the phenomenon.

Look up "fusor" and "pyroelectric fusion", and while you're at it, look up "sealed-tube neutron generator".

People use fusion as a neutron source, or just to say, "Look, I made fusion happen!" It's not a big deal, but they pour in a lot of electrical energy to get a little bit of fusion energy out, so it's not a power source.

Pretty interesting devices
