I am trying to figure out what kind of liquid, if any, can be used to severely impede or slow human motion without killing or severely damaging their bodies (IE if after being submerged in this liquid they need to spend a long time in the hospital, or are permanently disabled in some way.) Experiencing pain or minor side effects is acceptable, however. I am planning on using this fluid for the following while piloting a mech-type vehicle of approximately 13 feet tall, similar in design to the method-2:
- Shock Absorption, such that the pilot does not become incapacitated and sustains minimal injury in the event of a crash.
- Movement Impairment, such that a pilots movements are impaired or prevented in some way by the liquid that does not induce paralysis.
- Bonus: Nutrition, such that the pilot can use the fluid to satisfy his/her basic nutritional requirements by consuming some amount of it (they don't have to like it though). This is, however, an optional point.
A response to some comments I anticipate getting, in the hopes of being more clear for everyone:
Why do you need to stop the pilot from moving?
The way I envision it, the pilot must be kept relatively still in the sitting position, and would have a specialized suit that utilizes technology similar to this to move the robot. More moving parts means more things that can go wrong, and I figure a setup like you see in pacific rim has significantly more moving parts than some sensors, a filtration system to keep the liquid clean, etc. on the inside of the cockpit.
What you are describing is not possible with current or near future technology!
This is not intended to be near future, and I am basing it on technology that exists today to keep it at least loosely based on science, so please feel free to use more futuristic versions of modern or near future technology.
There are more effective ways of keeping your pilot still/protecting them from crashes/etc.
By all means please share any alternative ideas that accomplish the same goals with these constraints, however please also keep in mind the cost of the idea. Regardless, thank you for your enthusiasm, it is greatly appreciated.
