So my biomachine person, who will go by bob for the question, his very unique. He has machinery replacing half his organs and skeleton. Bioengineered cells work alongside and support the mechanical parts of his body. He has an anti matter reactor in his chest which burns super slowly to produce electricity for all of the machinery in his body for centuries. His cells have been engineered to function off of raw electricity instead of converting oxygen and food (a type of bacteria do this so cells can theoretically do it too right?). Since solid wires would be impractical due to the constant shifting and dynamic nature of cells, he uses a special fluid to delivery electricity to all of the cells and machinery.
The question is what that fluid is. I know water is a conductor (apparently diluted water isn’t but with some salt it is) but I didn’t know if there was a much better/cooler option. I think a superconductor fluid would be pretty cool but most superconductors need to be very cold to work and so being in a liquid state seems hard and also the anti matter reactor would definitely warm it up above room temperature. So this “blood” needs too:
- Work at room temperature, preferably on the much warmer side
- Be an efficient means of transporting charge
- Would be nice but not necessary if it was easy to produce with organic elements (so bob doesn’t need to eat some weird ore to keep his blood pressure up)
- Would be nice but not necessary if it could double as a coolant since it is hooked up directly to the main internal heat producers and to the rest of the body to radiate said heat
So far salt water seems like the answer because I’m pretty sure it matches all of those boxes but it seems so lame alongside antimatter reactors, quantum computers, and bioengineered cells. But if there is much cooler, and maybe more efficient, alternatives please do tell!
