Design and Implementation of Energy Harvesting System from Slides

In carrying out daily activities, without realizing it, energy is wasted. Various new renewable energy innovations are implemented to convert wasted energy into alternative energy sources to meet electrical energy needs, including harvesting energy from wasted kinetic energy when children are playing on the slides. This study aims to design and implement an electrical energy harvesting system from the park slides, which is designed by putting a generator, gears, flywheels and mechanical components at the end of the slides. From the experiment, when the rotational speed of the DC generator reached 503 RPM, the system produced a current of 0.98 Ampere, a voltage of 15.98 Volts and a power of 15.66 Watts. The flywheel is used as a mechanical time delay so that the generator can rotate longer. It is shown that the DC generator was able to maintain a rotational speed of 526 RPM for 4 seconds compared to 2 seconds when not using the flywheel.
