Abstract

INTRODUCTION

Innovative devices are made to resolve some issues and utilize natural resources to lessen the effect of climate change. Adopting the usage of renewables could help lessen the utilization of fossil fuels which is the leading contributor of carbon dioxide emissions. A lot of researches have been conducted to find an efficient yet affordable way of harnessing renewable sources of energy. These ideas about the wind turbines inspired the proponents to create a small-scale horizontal axis wind turbine with spiral blades that could be used in urban areas that have low prevailing winds.

METHODS

Wind energy was collected by USS SHAWT in affirmation to the scope of delimitation of the study. The average wind speed was attained from the anemometer for comparison of results. Every error of the program was debugged with the use of Arduino Uno. The voltage of the charged battery was measured using the voltmeter and was compared to the results of the programmed voltage regulator.

RESULTS

Obtained results proved the efficiency of the prototype which was able to convert and produce a significant amount of electricity. First, the Standard industrial fan's low rpm of 673 produced 1.1 V, medium rpm of 869 produced 3.2 V. and the high rpm of 1054 produced 5.6 V. The turbine generated an average of 3.3 V when it was placed in front of a Standard industrial fan for 5 mins. Second, when the turbine was placed on the grounds, it produced 1.3 V in 30 mins, 4.5 V in 60 mins, 6.8 V in 120 mins, and a maximum of 8.1 V in 360 mins. When placed in the parking lot, the turbine produced 1.0 Vin 30 mins, 4.0 V in 60 mins, 6.2 V in 120 mins, and a maximum of 7.8 V in 360 mins. When the turbine was placed in the garden, it produced 0.8 V in 30 mins, 3.6 V in 60 mins, 5.9 V in 120 mins, and a maximum of 7.1 V in 360 mins. Lastly, the most efficient location where the turbine must be installed is at the school grounds of Pasig City Science High School. The turbine garnered an average of 4.7 V from 8:00 -9:00, an average of 4.3 V from 12:25 -13:25 and an average of 5.0 V from 15:15 -16:15. The sum of the average voltage produced is 14.0V, the highest among the three locations.

DISCUSSIONS

USS SHAWT had successfully converted wind energy into electricity even with varying rpm, time, and location. USS SHAWT can be a precursor in the harnessing energy from the wind source of the Philippines that could help mitigate the effects of global warming and could also contribute to the betterment of the economy.
