More appropriately, I may be thinking of fusion, which leads to what is the difference between that and what we currently use?
In: Physics
We do have nuclear power for some cities – that’s what a nuclear power plant does.
Having a household reactor would be extremely difficult and dangerous.
It’s also difficult and dangerous in military ships/submarines, but it’s worth it for the advantages (unlimited range, etc.). A nuclear sub can afford the specialized crew.
And nuclear powered satellites are a totally different system – it’s more like a nuclear battery that provides a low level of consistent power for a very long time. Even those are only used when other options (like solar panels) won’t work.
