Proximity boots

Hi,

A brief overview of zero gravity footwear for use on metal surfaces.

The boot consists of a variable magnet with a sensor which determines
the distance from the surface beneath the boot. The magnetic force
increases with boot distance from the surface and is calibrated to 1
Earth gravity, so that when the boot is in contact with the surface it
is at its weakest. This allows the user to walk in comfort across the
surface.

Now all we have to do is build a couple of space elevators so we can
get enough metal up there to make the boots practical.

Best,

Stephen G
