This paper tells us about how we can convert pendulum motion of swing into electrical energy. Swing is generally used by children for playing in parks & playgrounds that will produce electricity during its use. During swinging pendulum motion of shaft transfers its motion to flywheel. This rotary motion of flywheel is transferred to low RPM generator which generates electricity in small scale. On the other side of shaft crushing mechanism is connected, which can be used to crush plastic waste collected in the park or playground.
