Abstract
Abstract Systems of high-efficiency, continuous, electric-powered transportation for urban areas comprise a plurality of the following systems in various combinations: (A) Dependable, continuous transportation is attainable by everaccessible, external systems of continuous propulsion of individual and multisection vehicles by imparting successive impulses thereto. (b) The propulsion systems and threedimensional guiding systems include resiliently yielding components of downward-directed pressure, serving to maintain positive, adequate traction between the driving-guiding systems and the tractional surfaces on successive vehicles for their propulsion at widely ranging operative speeds including speeds designed to propel vehicles buoyantly above ground. (c) Automatic timing systems operative to maintain the successive vehicles on headway time measurable in seconds, serve to provide ever-ready availability of transport. (d) Continuous loading systems include continuous, speed-adjusting load transfer systems in temporarily unitary relation with successive vehicles on short headway time, adjustability of loading speed establishing transport capacity of the systems. (e) Aerodynamic control systems serving to minimize head-on air resistance to movement of vehicles operative to aircraft speeds, comprise all-weather inclosure whose cross section varies inversely to vehicle speed change and embodies air passage for eliminating differential of pressure between air masses between vehicles. (f) All-electric automobile transport in a wide range of highway speeds and distances beyond stored power capability of electric automotive vehicles, is attainable in combination with the external, electric propulsion systems as in (a) and electric generator in each vehicle restoring the automotive power capacity while powered from vehicle propelled externally.
