Nuclear power is a good idea, as well as being really cool.
I agree. If regulated right, be it by a crew or a computer, the chance of failure is slim. On top of that, its the most efficient fuel we probably know, as far as mass and energy go. Iirc, a kilo of uranium makes ~70tril joules of power. A perfect mass to energy conversion is 90tril joules.
The only "perfect" reactor is antimatter, where half a kilo each of matter and antimatter make 90tril joules. But, take away production costs, all we really have is insane energy storage, not production. If we want maximum efficiency for antimatter reactors, harvest from thunderstorms or the sun or radiation belt. Or, better yet, an antimatter solar system. They probably exist. Do we know the difference between a matter star and antimatter star? Probably not. It'd be guess and check but once we find a pool of antimatter you just know future power companies are gonna use their machinery to rape the system and masturbate over their ridiculous energy production.
Future power sources always has and always will be my favorite subject to go on a tangent about. Future anything, but power is my favorite. If you ever want to talk about that stuff for no reason, you know who to call. <3
