Thanks for the monopole-idea:-) Oh, two new posts.

You are thinking about a kind of wind-tunnel that pulls downwards? Sounds windy, and there are better solutions for gravity gym available. Have you seen a motorcyclist go full circle inside a well? The speed sticks him to the track, so that he can go round and round and round. In weigtlessness where nothing is pulling you down, you can do the same with a bike (that has to stick to a track in the wall offcourse) so that when you ride round and round and round in the track-circle (that can now be a horisontal) you make your own gravity. Since you are riding around, looking foreward, and perhaps have som strips or lights or something in the room that shows that you are moving, you wont get seasick, and can then enjoy one G if you are in okay shape, or two, maybe three G if you are in good shape. NASA have experimented with this, and found out that ordinary not-so-sporty people can create a sideway-G this way (with one normal earth-G downpull as well). For such a gym, Im sure other kinds of things then bikes can be installed in the track to allow you to create the foreward, round and round pull - perhaps a rowingmachine for arm-training. Or one can have two tracks, one with a rowing machine, and one with a bike,
