Have you people heard of the Lord and Saviour gyroscope?

And when anything hits it, the explosive debris of the flywheel will bisected the ship. That is a risk I’m willing to let my drones make. The more high speed debris on a retrograde intercept of the enemy fleet the better. A gram of osmium traveling down the length of a needle ship at 100 km/s inside the armor is a total loss anyway, might as well make pretty explosions for YouTube.

Counterrotating pairs works just fine.
Even with structural mass it's orders of magnitude superior to chemical cell technology, which also has a limited lifespan (usually measured in tens of thousands of duty cycles) whereas properly designed flywheels are effectively eternal machines with lifespans measured in millennia.

Momentum wheels in larger turrets are a kind of unspoken energy storage, and should be bombs.
Nuclear reactors are generally not bombs IRL, but if you push them to be as hot and as light as ours and then throw bullets at them you should get some interesting results.
Fluorine microrockets should be bombs. Some of the capacitors should be bombs. Paper-thin radiators probably shouldn't stay on during high g maneuvers, and nukes should kill crews in calcium foil crew modules with radiation.
Generally CDE leans towards excess survivability, which is frightening because we're already flying rocket-propelled pinatas with armor literally made from tin foil and styrofoam.

I approve of this post.

I've contemplated the possibility of applying the technology of Saab's Gottland-class submarine for spacecraft use. It's a diesel-electric design but when submerged it has a 75kW Sterling-cycle engine that uses LOx as an oxidizer to combust the diesel, thus allowing the vehicle to remain submerged for weeks. Granted, it's got the ocean of nice, high specific heat water to aid in heat rejection. I see the primary application for this sort of thing as being for low-power, low mass drones that make use of bipropellant propulsion. So instead of having tiny RTGs to power weaponry, you combust a small amount of dV to run the Stirling engine. Such a setup is less resource intensive than a coin cell-sized RTG, can be lighter in weight, is easily produced via the additive manufacturing techniques CoaDE implies is used at a large scale, and offers up to 30% efficiency depending on heat rejection temperature. The weakness is that it does consume fuel instead of using the thermoelectric effect, makes use of multiple moving parts, and has relatively low heat rejection temperatures, similar to stock RTGs if you're looking for maximum efficiency.

Might be interesting, but so do batteries, solar panels, fuel cells and generators connected to the rocket exhaust (either MHD-generators or classical generators connected to turbines in the exhaust).
