An experiment has been carried out in order to convert oscillatory motion of simple pendulum into rotatory motion which is further transformed into electrical energy. For performing the experiment, a 52.07 cm length vertical pendulum of aluminium attached with a bob of 700 gm weight is connected to a threaded screw axle of 6 mm outer diameter. The wheel is connected to threaded screw axle with the help of ball bearings of 6 mm diameter. The gear ratio of pinion and wheel is 1: 6. The pinion is connected to a 6V step up gear generator which converts rotatory motion into electricity. The step up generator produces electricity which goes to MPPT (Maximum power point tracking) circuit where alternating current is converted into direct current using a rectifier. The generated direct current charges the two batteries of 4V each connected in series which act as a source of electricity. This innovation can be used to provide electricity in rural areas where there is a shortage of electricity. It can also be used to reduce the power consumption done by electrical appliances. After the completion of experiment we came to a conclusion that this working model is the simplest and very low cost source of electricity generation which will help in solving the electricity problems all over the country especially in slum areas.
