In Arthur Clarke's and Gentry Lee's Rama series, human beings are submerged in tanks of water and spend most of the day subjected to 10G acceleration for hours at a time.
My question is - does water (or any liquid) actually make any difference in such cases?
Being submerged in water would certainly dampen some sudden motions, but when you are accelerated at 10G, your organs is also accelerating at that rate, regardless of your surroundings. Your blood would still pool to whatever was the "bottom".
I know that pilots use pressure suits to help them stay conscious during high G maneuvers, but this lasts up to a few minutes and those suits actually put pressure on lower body to squeeze the fluids out, water tank cannot do that. Or am I wrong?
