Abstract
The invention presents a dual-mode hybrid high occupancy capacity vehicle (HHOCV) with a novel electrical energy and power storage application, electrical energy and power source and charging system in conjunction with additional methods to maximize the energy and rate of use such that the overall system is far superior to multiple personal transportation vehicles and roadway based catenary mass transit systems, including, but not limited to petroleum-only fueled high occupancy capacity vehicles. The HHOCV exhibits a novel battery charging system by taking advantage of existing track/trolley/catenary facilities for electrically charging its electrical storage media at a high energy rate so as to minimize disruption of such charging services, and is not confined by physical boundaries or limitations and may travel off the power source to the existing common roadways returning only to be recharged. The design incorporates software controllers and other devices to maintain the energy transfer rate and is of such physical size that the overall invention may either be retrofitted to existing buses or designed within new high occupancy vehicles.
