#if we ever achieve FTL travel I swear there’s gonna be a steam turbine involved somehow

And the different types of energy storage we’re using to solve the problem run the gamut from “advanced electrochemistry” to “caveman.”

-BATTERIES: new large-scale batteries utilizing nanotech cathodes and reduced rare earths. B-, “big battery” is just kinda obvious.

-HOT SALT: use the excess energy (or just big mirrors) to melt sodium, use the heat to power steam turbines overnight. A, no matter how far we come we must never forget beloved steam turbine.

-SPINNING: build a massive gyroscope, speed it up when you have extra power and slow it down to generate power back. A-, Steel Ball Run wasn’t my favorite JoJo series.

-HEAVY THING: lifting it up takes power. Lowering it generates power. It’s how a grandfather clock works. It’s also just a heavy thing. A+.
