Let me know when good old fashioned American ingenuity figures out how to increase the force of gravity on demand.

Read the High Frontier by O'Neill. His factories have varied gravity gradients based on their distance from the rotational diameter. This is why he speculates that at the end of there mile lon cylinders you could "climb the clyinder wall and gravity would be decreasing as you"go up". He speculates that a pair of wings would allow a "spacer" to fly!!!
