NOVELTY - The system has an electric generator (130) including a first portion (132) coupled to an input shaft (122) of a torque converter (120) and a second portion (134) coupled to an output shaft (124) of the torque converter. The electric generator generates electrical energy when the first portion of the electric generator rotates relative to the second portion of the generator. A charge storage device (150) stores a portion of the electrical energy as stored electrical energy. An assist motor (170) is coupled to the drive shaft, and receives the electrical energy generated by the generator.    USE - System for harvesting electrical energy for an engine e.g. internal combustion engine, petrol engine, diesel engine, gas turbine engine, rotary engine, Wankel rotary engine, barrel engine, petrol-electric hybrid engine and diesel-electric hybrid engine, of a vehicle e.g. automobile, lorry, motorcycle and train (all claimed).    ADVANTAGE - The electrical energy stored in the charge storage device can be used for driving the assist motor so as to improve a fuel consumption rate of the engine. The electrical energy applies accelerating torque to the drive shaft as the vehicle accelerates using the assist motor, so that vehicle acceleration can be increased without using extra fuel, and fuel economy can be improved. The system reduces energy waste, and obtains better performance without additional fuel consumption. The system allows an assist motor controller to prevent overcharge of the charge storage device. The charge storage device can be manufactured at lower cost.    DETAILED DESCRIPTION - The first portion of the electric generator is a rotor, and the second portion of the electric generator is a stator. The electric generator is an alternating current (AC) generator and a direct current (DC) generator. The charge storage device is a capacitor, a pseudocapacitor, an ultracapacitor and a battery i.e. lithium ion battery. INDEPENDENT CLAIMS are also included for the following:    (1) a method for harvesting energy for a vehicle    (2) a storage medium comprising a set of instructions for harvesting energy for a vehicle.
