Those have been researched and tested for decades and the tech still hasn't caught on. They just don't put out enough power to be useful for much more than a clock circuit (not even enough to power a full watch, just keep the time).

I have serious doubts they're going to suddenly become viable anytime soon.

Any useful energy production from nuclear is basically just making steam to run turbines. Same with coal but you know.

Sometimes we take the hot rocks and ship them to other planets too.

We have rocks that do math, transmit electricity, and fly us through the sky.

When you get reductive about the natural sciences it all just boils down to applied physics which is applied mathematics.

But engineering and technology? Applied geology.

(/s because I’m not going to acknowledge that geology is applied chemistry and so on)

[Encased mentioned] I love that game
