Rain Water Energy Harvesting System
Malaysia being a developing country is continually in exploring an alternative source of energy towards producing electricity. The demands for utilisation of natural renewable sources such as solar, water, biomass, wind and geothermal are increasing to aid in electricity grid stability. Hydropower technology is targeted from one of the renewable energy technologies to accomplish the current power demand. In the context of hydropower technology, rainwater and river are also viewed as renewable energy. The turbulent water resulted from rainwater or river can generate energy which is stored and convert into electricity. Thus, it is called hydropower or hydroelectric power. This paper studies the performance of Rainwater Harvesting (RWH) system which harvesting potential energy inherent in high rise buildings by using turbine which installed on the ground. Moreover, it is capable of generating power up to 20 kW with practically no environmental impact. RWH system using the collected rainwater from a storage tank which located at the top of the high rise building to produce electricity. Electric appliances such as a light bulb, television, radios, refrigerators, and food processors can harness this generated electricity. In Malaysia, every high rise building is equipped with a different high of the rooftop as well as the pressure of the rainwater flow through the pipeline. Therefore, the power produced relies on these factors. Several basic parameters allow to design and compute a model of the RWH system. This research presents a model description of the RWH system using the Simulink library from MATLAB to perform modelling, simulating and analyzing, due to well developed libraries.
