The fusion-fission hybrid will use high-energy neutrons produced by a fusion reaction to trigger fission in surrounding materials thereby boosting energy output and potentially reducing long-lived nuclear waste.

It was a joke. We have invented fission and fusion, but the reactors are still attached it to a Rankine Cycle.
Also, the radius would be considerably larger than the sun. Perhaps not encapsulating The Earth, but that seems like a potential death sentence, if we built a Dyson Sphere rather than a Dyson Swarm
