Okay, here is a general "immovable rod" transportation device. It uses two rods together on a lightweight frame. Using it is similar to using stilts.
Basic design (see diagram): each rod is rigidly attached to the top of a lightweight wooden pole. At the base of the pole is a stirrup. The length of the pole should be such that standing in the stirrup, the rod is about chest height. The rod is position as a handgrip, with the button in the "thumb position" for easy operation. The two wooden poles are joined by ropes so that a rod cannot be dropped or taken away. Finally, rings are privoded for attaching a safety harness, so the user cannot be dislodged.
Climbing: Activate one rod, climb on, and activate the other rod. Feet should inserted snugly into the stirrupts, with hands on grips. Now deactivate a rod with your thumb, lift the pole 6-12 inches, and reactivate. Repeat, alternating rods. Since feet are in stirrups and the poles are rigid, the legs can be used to help lift the rods, so weight is not on the arms.
The device can also be used to walk horizontally over chasms, water, etc, in the manner of stilts.
If the rods were joined with a rigid sliding-type bearing instead of ropes, it would be possible to lay the rods horizontally and hang from them, extending first one hand and then the other monkey bar style. Heck, it wouldn't be hard to modify it so you could *sit* on it like a go-cart and push the poles forward with your hands.
It seems like there ought to be some way to create a pulley device (sort of like a ski machine) that would allow you to use your body weight in a stirrup to propel the frame upward. But I'm not mechanically inclined enough to figure it out... if only I were a gnome...
Of course at some point, it's worth the money to spring for winged boots or a flying carpet and just skip the hassle.
Edit: hmm, I attached a JPG but it disappeared into the ether. Oh well.
