     When I worked in the special effects business, we used to use these
     all the time to move heavy stuff around. It actually doesn't
     require a "real flat" floor (1 cm grooves aren't a big issue).
     Think about them as small hovercraft. It also doesn't take much air
     pressure to lift things (large area * small pressure).  For
     instance, folks build small hovercraft using electric leaf blowers
     as the pressurization fan to support a disk some 1.2m in diameter
     which will easily support a couple people.

     The lift pads we used were about 30cm in diameter. 1 psi (7kPa)
     lifts about 50kg. Moving around 1 ton things with 4 pads wasn't
     unusual.

     The rougher the floor, the more airflow you need.

   James,

   Do you have any web sites that show such a contration using leaf
   blowers ?

   thanks,
