Concept
To make a rotating space station.
Make the centrifugal force of rotation to mimic the force of gravity.
Research has shown that 2-3 RPM are tolerable to most people.
I have calculated the total dimension (diametrically) of the system that will be needed to achieve a desired centrifugal (gravitational) acceleration keeping in constraint the number of rotations the rotating module is doing in unit time.
Why should it interest the future?
New research will open in making truss based systems.
Gives rise to spin off technologies.
More research on human behaviour to rotating environment.
Ideas will be needed to be conceptualized to start and stop such a massive system during docking of incoming spacecrafts.
