Fraser CainMotorcyclists can drive inside a cylinder, using speed to generate artificial gravity that sticks them to the wall. A similar technique could be used on the Moon, allowing astronauts to maintain their cardiovascular and muscles on the Moon. Researchers put study participants into a "Wall of Death" ring, suspended them with bungee jumping bands that mimicked lunar gravity, and taught them how to run horizontally. This should be possible on the Moon without support.
