Abstract
A series of capacitors arranged in a way to prevent build up of electric flux between the plates of adjacent capacitors. The capacitors are electrically wired and provided with means to charge them by deriving electrical energy from a power source. The capacitors are also provided with means to discharge them one at a time at predetermined interval and during discharging, momentarily activate a motor. As the motor is activated during the discharge event of a capacitor it rotates a shaft which has means to engage and rotate a second shaft mounted with a flywheel. The first shaft will have means to disengage itself from the second shaft in between the discharge events of any two capacitors. The second shaft is connected to a third shaft through a gear box allowing it to rotate at desired rpm. The third shaft is also connected to a generator to produce electricity. Before the start of the process of discharging the capacitors the second shaft starts rotating with the help of a starter and a starter gear to overcome the inertia of rest of the flywheel.
