The present disclosure includes cargo loading systems and components including cargo systems utilizing one or more air cushions to elevate one or more cargo shuttles. The air cushions are formed by one or more air curtains, which include pressure compensating seals. The seals allow the air curtains to contact and seal against a floor panel, reducing leakage from the air cushion.

An air cushion cargo shuttle for loading and unloading cargo on an airplane is described. The air cushion cargo shuttle includes a first inner air curtain defining a first volume of pressurized air. The air cushion cargo shuttle also includes a noise barrier curtain enclosing the first inner air curtain. The noise barrier curtain is adapted to trap air leaking from the first inner air curtain.

A hoverbarrow apparatus is provided to mechanically lift objects to be transported using a cushion of turbulent air as the force providing the lift. The air cushion methods of lift drastically reduce the physical exertion necessary for motion, forward or reverse, required to perform the task of transporting objects. The air cushion further improves the performance and use of the barrow by allowing the barrow to float on turbulent air over objects in its path significantly reducing or eliminating impressions and divots in the surface currently associated with the present wheelbarrow technology.

A structure equipped with a fuel cell system, wherein the structure comprises: a skirt configured to form an accumulation space between a bottom of the structure and the ground, an air supplier configured to supply off-gas, which is discharged from the fuel cell system, to at least one space selected from the group consisting of the accumulation space and an internal space of the skirt, and a pressure discharger configured to discharge pressure accumulated in the accumulation space to outside of the skirt from a lower end of the skirt, and wherein lift is imparted to the structure by supplying a predetermined amount of the off-gas from the air supplier to at least one space selected from the group consisting of the accumulation space and the internal space of the skirt.
