ABSTRACT:
An overhead transportation system comprising for a depending and longitudinally traversible vehicle an overhead trackway as a pair of longitudinally slottedly vented tubular conduits maintained above the earth's surface with a series of pillars and having an overlying protective shield. The vehicle powering means comprises a pair of co-traversible jet engines situated within respective conduits and connected to the underlying vehicle with a dual-arms hangar means along which arms the engines' fuel-line extends. The trackway is lubricated from a longitudinally extending lubeline with syncronizeably operated nozzles spaced therealong and communicating with the conduit innerwall, and a longitudinally extending troughline collects the liquid lubricant, there being provision for re-cycling the lubricant for high-pressure re-injection into the conduits through said lubeline nozzles.
