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.

Not that I'm aware of. All our nuclear commercial power plants are just plain old nuclear energy boiling water. We're gonna use a damn Dyson Sphere to boil water......

We have bombs that use a similar starting mechanism, but they aren't exactly useful energy production.

I meant that we use neutron breeders to turn certain fuel rod waste into fissile plutonium I think.

The difference with the Chinese invention is that you don't need to transport the waste to a separate breeder.

Isn't a Dyson Sphere supposed to use solar panels? I don't know how you would find enough water to cover the interior of an object with the radius of the Earth

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
