Estudos sobre a geração de energia elétrica com águas urbanas

Abstract

Each day the number of studies on new sources of energy, better use and greater efficiency has grown. There is the possibility of transforming the kinetic energy of urban waters into other forms of energy, such as electrical. To build a hydroelectric dam, environmental impacts are generated. Therefore, if it is possible to generate a relevant amount of electricity with urban waters, such as residential waters, the need for hydroelectric plants could be reduced and thus reduce impacts on river basins. This research has as one of its objectives to study the transformation of the kinetic energy of urban waters into electrical energy, through small and low cost generators that were built. In addition, to analyze advantages and disadvantages between the generation of energy from hydroelectric dams and the generation of energy from urban waters. In Brazil, research on energy generation with urban waters is still scarce. The generator and turbines were built with parts that were adapted, the assembly and adjustments were carried out manually. Tests were carried out with direct water from the supply network, reservoir water and rainwater. Voltage and current readings were taken, apparent power estimates were made. The designed and constructed generator worked by successfully turning on six three-volt LED lamps simultaneously. A voltage of approximately seven volts was generated using the generator. It can be seen that there is a possibility of achieving better results with new research using more efficient equipment.
