Introduction
The electricity demand is increasing very rapidly, which requires building more fossil fuel power plants to supply such load. However, fossil fuel plants suffer from numerous drawbacks. They are main source of pollution. Tons of greenhouse gases as CO2 are released, which causes global warming, desertion and flooding. Moreover, traditional power plants have high running and maintenance costs [1,2]. Furthermore, the limited reserve of fossil fuels motives the search for alternative energy sources.
The researchers are searching for eco-friendly and sustainable power source. Solar and wind energies are investigated. However, the stochastic nature and weather dependency reduce the advantages of these sources. Moreover, wind energy involves complex and costly system for generating electricity [3].
This article proposes a new scheme for generating electricity from human footsteps. A simple and efficient mechanical device is proposed that converts the footstep pressure into energy. An efficient and simple electronic circuit is advised for harvesting the generated power. A prototype was built to test the functionality of the proposed scheme. Matlab and its dynamic platform Simulink are used for stimulating the proposed systems. The practical and simulation results are introduced to validate the proposed generation method.
Conclusion
Innovative scheme for generating electricity from main human activity, which is walking advised in this article. Simple and elaborate design for the energy converter convert human footstep into mechanical energy designed and implemented. This energy converter could be integrated with structures as stairs. PMDC generator, diode rectifier and boost converter are attached to the prime mover. The rectifier is used to rectify the output voltage as it fluctuates due to the mechanism of shaft rotation. The produced power is sufficient for charging portable devices. The practical setup validates simulation results, which proves the feasibility of this approach.
It is worth to mention that this scheme is notable for producing a power level required for a reasonable load. Moreover, this arrangement requires high flow of the people to generate electricity.
