Re: A never-ending study on how to mess up humans...
many science fiction authors have written about viable artificial gravity solutions. Perhaps the more obvious one could be the 'gemini tether' someone else mentioned.
OK here's the idea: Extend two "gravity modules" 10 to 20 meters, using very strong cables [like the ones used for elevators on Earth]. Provide an inflatable tunnel between them, made of the same stuff you might find on a typical work site, going down a manhole or something. It all collapses nicely for launch, acceleration, and deceleration. For the bulk of the trip, it's extended. Careful use of thrusters cold provide the spin, and get rid of it when it's time to decelerate. And sliding weights (computer controlled) could be used for balance, something you might find in an industrial washing machine for the spin cycle [if they're not just using water for the same purpose].
you don't need a full 1G, either. 1/4G or 1/2G would be better than 0G. And you can just minimize the disorientation that fast-spin might cause, rather than trying to eliminate it entirely. [many engineering choices are compromises between multiple ideals, like rounding off at 'enough' digits instead of calculating to ridiculous precision...]
In any case I remember reading books written in the 1950's that seemed to have most of these details worked out. Most likely some bright bulb could come up with a workable solution for a reasonable cost.
but, there's more MONEY in "researching", and the scientists who do the research will get to play with lots of cool toys at (public?) expense...
