Liquid Anon is my little OC, a total badass, with the ability to assume any form and color at a whim. Donut steel!
A magnetorheological fluid (MR fluid, or MRF) a type of smart fluid in a carrier fluid, usually a type of oil. When subjected to a magnetic field, the fluid greatly increases its apparent viscosity, to the point of becoming a viscoelastic solid. Importantly, the yield stress of the fluid when in its active ("on") state can be controlled very accurately by varying the magnetic field intensity. The upshot is that the fluid's ability to transmit force can be controlled with an electromagnet, which gives rise to its many possible control-based applications.
The basic idea is that Anon's body is this magnetorheological fluid, but using nanomachines, son. These machines are in the micrometer range (100 micrometers) and are capable of generating their own magnetic fields. When in a field, the nanite can choose to block it out, or line up with it and generate another.
That's the basic concept, but ignoring the nanites, their carrier fluid has some... unanswered question in terms of composition.
What does it have to accomplish?
- Nanites can be suspended in it: I mean, that's why the magic happens!
- Magnetic permeability: I don't know why, though ^^
- Chemical stability: Anon is 100% fireproof and resistant to acids and bases, except for that time when a certain person poured ClF3 all over him.
- Lightweight: Anon already has battery problems and is dense enough, thanks to his nanites. The carrier fluid should add minimal weight.
Any bonus (maybe energy storage) function is appreciated, but not mandatory.
Judgment process: Objectives are ordered into priorities, the first (most important) is worth n points, the next is n/2, after that n/2^k, the highest score wins.
- Everything in the "What does it have to accomplish?" ordered list, already in priority order as well.
- If there's something extra that gives an edge in combat and doesn't involve CLF3 or the Nuremberg trials
What carrier fluid should I use, that meets these criteria?
Feel free to build the solution up from the molecular level.
I went forward and addressed internal and external heating, with aerogels and a heat radiator.
Note: Though I could use nanomachines for everything, it's both more complicated and energy demanding than fluids, so it really is the last option.
