It is known that the efficiency of an industrial process diminishes, the longer the path from the conversion of an energy into motion to utilising the motion. Generated rotary movement can be utilised directly as the rotary movement is produced, by means of threaded tubes. This is based on the fact that flowing media such as air or water tend to curl inwards, producing suction. If a threaded tube is rotated about its longitudinal axis, water flowing through is forced to wind its way through while curling inwards, and to generate the suction in the process. A suitable drive for this application is the electric internal-rotor motor, if a threaded tube is employed as the axis thereof. This produces, if enough current can be generated by means of generators, the lift and thrust for aeroplanes and helicopters, and as a result runways for landing and takeoff are no longer necessary, because the rotating threaded tubes, which are constructed so as to narrow downwards, compress the air into supporting columns or into driving columns. Railways could float on carpets of air, according to my "floating train" patent application, or aircraft could be flown along current-carrying wires at speeds of approximately 500 km/h from terminus to terminus, from elevated platforms. However, the rotating threaded tube is also suitable for mixing by means of the inwards-curling motion, for example to swirl air and fuel prior to combustion. In the rotating threaded tube, sand and water can ... Original abstract incomplete.
