Eco-electric energy generator system using human exercise activities

Abstract

Today human need for electrical energy is very high. For that we need to find an alternative power plant renewable energy, especially environmentally friendly. One type of an environmenttally friendly power plant is a generator which is harnessing human-generated energy when exercising by using a static bike. This equipment is used on average 6 hours per day at 5.00-8.00 hours and 17:00 to 20:00 hours. In this research, a power plant system by utilizing human motion exercising from wheel rotary mechanics, generators, BCU (Battery Control Unit), and battery will be designed. The rider can see from the LCD when the battery condition is full, the battery is charge, the battery does not get energy from the generator, inverter on, inverter off, battery voltage and generator voltage. At the testing stage, 14 participants cycling for 15 minutes produced electrical energy on average of 594 Joules, with an age range of 20-23 years old. The resulting energy can turn on the light 3 Watt between 160 -251 seconds or 198 seconds on average. When accumulated 14 cycled samples with 15 minutes each (total 210 minutes) can generate 8313 Joule electric energy and can turn on 3 Watt lamp for 46 minutes 11 seconds.
