Wasted Energy

<span>Electrical energy is important and had been demand increasingly. A lot of energy resources have been wasted and exhausted. An alternative way to generate electricity by using a population of human had been discovered When walking, the vibration that generates between the surface and the footstep is wasted. By utilizing this wasted energy, the electrical energy can be generated and fulfill the demand. The transducer that use to detect the vibration is a piezoelectric transducer. This transducer converts the mechanical energy into electrical energy. When the pressure from the footstep is applied to the piezoelectric transducer, it will convert the pressure or the force into the electrical energy. The piezoelectric transducer is connected in series-parallel coonection. Then, it is placed on the tile that been made from wood as a model for footstep tile to give pressure to the piezoelectric transducers. This tile can be placed in the crowded area, walking pavement or exercise instruments. The electric energy that generates from this piezoelectric tile can be power up low power appliances.</span>

Renewable Hydrogen

Hydrogen is likely to play a significant role in the concept of low-carbon power generation in support to renewable energy systems. It is abundant, eco-friendly, highly efficient and have the potential to be more cost-effective than fossil fuels provided that the engineering challenges associated with its safe infrastructure development, economical extraction and storage are solved. Presently, about 50 million metric tons of hydrogen is generated on a yearly basis, most of that is used for oil refining and ammoniac production. Other applications include electric vehicles, power to gas and power generation, etc. This study focuses on the use of hydrogen for power generation. The main goal is to investigate technical and economic performances of a renewable hydrogen-based energy system as an alternative to diesel generators for powering a remote telecoms base station. The proposed energy system consists of a photovoltaic generator, an electrolyser, a fuel cell, a hydrogen tank, a battery storage system and a power-conditioning unit. The system is simulated using Homer Pro software.

Design Variables

In the past decade, there have been numerous studies which showed the feasibility of harvesting electrical energy from vibrating structures. The main goal of this study is first to generate a Finite Element (FE) model using ANSYS to verify an existing harvesting model. This FEM model can be used as a base for designing more complex harvesters. The second goal of this study is to optimize the parameters of a simple cantilever harvester to maximize the power generation from ambient mechanical energy. A distributed parameter model and its modal solution are used to identify the design variables through a parametric study. The results obtained using the distributed parametric model is compared with the results obtained using ANSYS. It is of interest to ensure adequate power generation under non-resonant conditions for a broad band excitation. The average power within a certain frequency range is used as the cost function to define optimization problem along with some geometric and physical constraints. We found that, in certain frequency ranges, the parameters can be optimized to generate maximum power. Having validated the methodology, work is in progress to design and optimize harvesters with complex geometries.

Sinusoidal Pulse Width Modulation

Abstract The work proposed in this paper focuses on providing an effective solution to shortage of power in rural areas with an effective technique implemented in an economically feasible way. The traditional Inverters used for either residential or commercial purposes consume electrical energy from the grid to fulfill the charging and discharging of the battery, which may lead to overloading. The shortcomings of the traditional inverters such as Non-Renewable nature of power sources, increased cost of manufacturing, and multi-stage conversion complexity, are considered by the researchers for improvement. As a result, an attempt has been made to provide a cost effective renewable energy system with single stage topology for AC power applications. Single stage power conversion with allowed shoot through state is used here to avoid additional components and reduce the switching losses. Unlike the traditional inverters, the Quasi Impedance Source Inverter that is brought forward can be utilized as a Standalone system or a capable backup at the time of power outages. Sinusoidal pulse width modulation (SPWM) is applied to attain reduced harmonics which are measured by observing the harmonic pattern in Total Harmonic Distortion (THD) curve. The lab results obtained through MATLAB simulation confirm the noteworthy diminution of THD level in the proposed system compared to the reported one. Usage of Photovoltaic (PV) Panel to tap energy with reduced stochastic fluctuations due to high filtering capacity of the proposed circuit, eliminating the need of additional filters, is the uniqueness of this technique.

Power Generation Performance

Abstract The energy of mobile robots severely limits their range of motion and work capabilities. This paper proposes a method of capturing energy from the amphibious environment for a spherical robot with pendulums. The movement of pendulums is analyzed during amphibious movement, and a feasible scheme is proposed for a pendulum to capture environmental energy and convert mechanical energy into electrical energy. The mathematical model of the swing power generation is established based on the pendulum dynamic equation and voltage balance equation. The physics experiment platform and virtual experimental platform are built to analyse the power generation performance. Furthermore, the power generation mathematical models are established respectively for the spherical robot rolling on the slope and floating in the water, and the power generation performance is analyzed and summarized under different conditions. The results show that the proposed power generation method and scheme can effectively supply the energy to the spherical robot, can enhance the endurance of the movement in the amphibious environment, and provide theoretical guidance for the development of the physical prototype of the new generation of amphibious spherical robot.

Road power generation technology is of significance for constructing smart roads. With a high electromechanical conversion rate and high bearing capacity, the stack piezoelectric transducer is one of the most used structures in road energy harvesting to convert mechanical energy into electrical energy. To further improve the energy generation efficiency of this type of piezoelectric energy harvester (PEH), this study theoretically and experimentally investigated the influences of connection mode, number of stack layers, ratio of height to cross-sectional area and number of units on the power generation performance. Two types of PEHs were designed and verified using a laboratory accelerated pavement testing system. The findings of this study can guide the structural optimization of PEHs to meet different purposes of sensing or energy harvesting.

Electricity is the most general forms of energy used across the world. This paper focuses on designing a setup that leads to the generation of electrical energy which is going to waste when humans are walking. Footsteps are an untapped natural resources. This generated energy is, however, costeffective and nonhazardous for human. Electrical energy can be produced by converting mechanical energy using footsteps. Generating the electric power through the fabrication of footstep arrangement by a prototype comprises of a pipe, nozzle, unidirectional valve, water reservoir, turbine, and DC motor. Whenever pressure is exerted on the reservoir, water flows through the nozzle into the turbine and generates electrical energy. This energy is stored in the battery. This project will reduce the global warming and load shedding in a much cleaner cost-effective way. Since this project is related directly to the human movement, the weight of the setup is a crucial factor.
