Abstract
The RABBAT ELECTRIC HYBRID VEHICLES have no mechanical transmission of power, only ductile wires connecting various sections of the car.
The multiplicity of capacitor/battery units makes it easier for the vehicle designer to position them around for cosmetic or actual mechanical need, for better handling and safety.
A diode between the motor and battery ensures that there is never any backflow of current. The ultra-capacitor/battery units which are charged thru a plug-in or a pantograph from an external supply and by an internal engine/generator which could be H2/O2, liquid/gas, internal combustion/jet/rocket/explosive) running at a uniform most efficient rate without being affected by stops or starts, slowing or acceleration, from start to finish.
In this vehicle there is no juggling between application of internal combustion energy and electrical energy. It is sequential: fuel to electricity to motor drive, all the time.
The RABBAT BUS STOP where potential passengers wait for the bus, offers certain services and saves bus time by having customers purchase bus tokens or electronic tickets ahead of the bus arrival. Then they access the bus thru a turnstile. The RABBAT BUS STOP provides grid supplied electricity to the bus as soon as its railings make contact, during its wait, and until its railings lose contact with the external supply.
