WATER POWERED DC HUB CHARGER
WATER-POWERED DC HUB CHARGING SYSTEM Balbin, Burdeos, Cajuday, Malazo • Improvement of the green technology by using renewable energy involving water resource. • Guide to create a microscale renewable energy source for charging of low power DC loads intended for off-grid areas. • This research project covers fluid dynamics involving Heron’s principle, calculation of voltage output relative to amount of water in the containing vessel and validation of data and results using Pearson’s correlation technique. Fig. 1– Enabled Heron’s Fountain. Provided that the air tank has air, the water will resume to rise. Fig .2 – Disabled Heron’s Fountain. The execution of the system will increase by the volume of the tanks. Fig.3 – The Projected System. The concept is a closed system where the air will be enclosed in the system which will be achieved by closing the cap of the tanks. Fig.4 – 180 degrees rotating to reset. It is shown that the water and air circulating in the system will be back to their respective tanks. Fig.5 – Generating Power and Regulating Voltage. This picture represents the hydro-electric power generation with a voltage regulator that would efficiently give the estimated output of 5 volts. Bernoulli's Equation Decision Criteria There is a directly proportional relationship between two factors if the Pearson’s correlation value, r, is within 0.5 and 1, there is inversely proportional relationship when Pearson’s r is within -0.5 to -1, while there is little relationship when Pearson’s r is -0.5 to 0.5.

Multisim Simulation • The volume filled of the upper tank is directly proportional to the output voltage of the regulator side. • The voltage that can be generated using the micro-scale hydro turbine generator ranging between 4.622 volts to 5.038 volts. • The volume filled and the output voltage have a direct relationship, based on the Pearson’s correlation. • The Watered-Powered DC hub charger prototype is not a perpetual source of renewable energy. • In this study, the researchers proposed a design that utilizes hydroelectric energy at a micro-scale level intended for off-grid areas. • This research project can serve as a basis in the development of water-powered electric generators adapting the Heron’s principle with modified system. • Replace the turbine generator from 5 volts to 12 volts with higher power rating for some DC load applications. The level of the water on tank is hard to know, the researchers recommend to have a sensor or sight glass in every tank to verify the water level. THANK YOU!
