Surgery / cybernetics / medical stuff

I think it would be kind of cool if you could surgically add a nanobot repair thing that requires wielding fuel to function, so the crewmen slowly heals as long as they drink wielding fuel when it runs out. Also maybe toxin damage could happen after prolonged exposure to welding fuel as a balence, so the person's peak slowly decreases overtime. Also killing them could potentially make them spectacularly explode.
