A 25 mm thick wall forming a sphere that's 16.8 m diameter masses 24,350 kg. A 16 m diameter ring that's 7.2 m wide rotates within the sphere at a rate of once every 41.2 seconds moving at 32.7 kph (20.2 mph).

Coming in from the motionless zero gravity field, is a moving sidewalk that consists of 10 bands that are 0.5 m wide that move at 2 mph faster each. The ring masses 10,190 kg..

The sphere rotates in the opposite direction producing 1/9th the gee force as the cylinder.

Two astronauts in a swing attached by a cable 20 m long with two tanks of propellant separated by 18 m - attach and rotate 9.4 rpm to produce one gee.

A 0.5 cm diameter cable 20 meters long mass 530 grams and produces 1 gee of force outward.
