In the exercise cubicle there is a treadmill running at a fixed speed. The speed is marked on the cubicle door so you can select which running speed is right for you.
By not stopping and starting the treadmill energy is saved.
How it works:-
The treadmill belt is logically 'unravelled' into
a long strip. This wouldn't work so the next step is to join the ends and turn the strip into a flat circle like running surface with a hole punched through the middle to leave only the running width required. Since its flat it can be made stiff and run over efficient bearings.
In practice, the Low Friction Treadmill can be deployed in concentric circles to allow different running speeds at different radii. Simply build cubicles around sections of the track.

Similar but way too small to offer energy efficiency or give the illusion of a straight track. [bigsleep, May 12 2009]

won't a continuous looped track, no matter where
it is running, run at the same speed? If the track
was driving various sized wheels(concentric
circles) then they would run at different speeds. |

Ah, You propose 'different' tracks, with another
set of mechanics, for different speeds. |

Sorry, I thought it was an efficient way of using
one track to produce the different speeds. This,
of course, would need some sort of buffering. |

Maybe a track of segments where the fast bit gets
3:1 of the segment split compared to the slow bit. |
