    Prototyping Magnetic Boots!

    I had a strange dream the other night about making your boots. They just have too many limitations. I ended up designing something completely different. Picture this.. Boots, similar to roller blades, but instead of wheels you have treads. Think tank treads. Each individual link in the tread would be a poly magnet for maximum holding power. But when the tread rotated along, the poly magnet can peel off the wall as it continues along its track to go up the tread and come around again.A set of gloves similar to this could be made. Having a handle to grasp onto between the treads (assuming you make them with a pair of treads, left and right side of center). The treads would use a ratcheting system as not to work in reverse. Basically a one way tank tread being pushed up the wall. Then when...see more »I had a strange dream the other night about making your boots. They just have too many limitations.

Basically a one way tank tread being pushed up the wall. Then when said ratchet is unlocked, a flywheel clutch would engage allowing the treads to work in reverse, but at a very limiting speed. Allowing for a controlled descent at a pace that doesn't result in that old saying, "it isnt the fall that kills you, its the sudden stop".-MrGT

    << Previously MrGTIts been three months. I'm interested to see how your project has come along.I've also been thinking about certain problems with using them, to say, walk up a 90 degree wall. You would need some pretty amazing leg strength to keep your body level to the ground and not end up hanging with your knees bent. But that's also just thinking inside a box. Thinking from the outside would come up with some other wall climbing ideas, like magnetic gloves? Or a harness that would be worn around the torso, and perhaps connect to an extension protruding from the boot, like a pair of short skis. You could walk right up a 90 degree surface and your body could remain perpendicular to the wall the entire time.

    You are on the right track; however, you have a problem with your magnets. Research polymagnets. They are programmable magnets. Imagine the same strength (what? N60's?) with a twist. Imagine that the field depth (let's call it the range of the pulling force) being greatly reduced by about 90%. But, once you get up close there is a sudden increase in field strength. Using these magnets would make it easier to walk by giving you near instant freedom from the pull almost immediately as they break with the surface. As a bonus the boots won't attract or repel from each other when more than an inch or so away. Polymagnets are truly amazing. They are truly a mind blowing discovery/invention. They are also capable of much more. If you are reading this and haven't heard of these, then be prepare...see more »You are on the right track; however, you have a problem with your magnets.

    Using permanent magnets is of course the only way to go for and application such as walking upside down. But I can see an excellent use electromagnetic principle here.Wire all or most of the permanent magnets as electromagnets. But with a twist.. Wire them in reverse. Wire them so that when power is applied they cancel out the magnetic effect of the permanent magnets. This can be attenuated so that you simply weaken the magnetic field strength just enough to make "lifting" your foot near effortless. Maybe putting an electrical switch in with your toes. Squeeze your toes down to activate the reverse magnetic effect. Possibly using a variable resistor as the switch to allow you to attenuate the power on the fly!
