If you just scale up the donut reactor, Tokamak, and improve your surface-to-volume ratio, it becomes much easier.

And you can absolutely, in my opinion, I think just anyone who looks at the math, you can make a reactor that generates more energy than it consumes.

And in the limit, you just have a giant gravitationally contained thermonuclear reactor like the Sun, which requires no maintenance and it's free.

So this is also why why would we bother doing that on making a little itty bitty Sun that's so microscopic you'd barely notice on Earth when we've got the giant free one in the sky?

If people want to have fun with reactors, that's fine.

But it's not a serious endeavor compared to the sun.

It's sort of a fun science project to make a nuclear reactor but it's just peanuts compared to the sun.
