Grade 10 students develop alternative energy sources using poultry waste, algae, solar power

Trying their hand to develop significant advancements in sustainable energy, two groups of Grade 10 students have pioneered creative methods to generate electricity using unconventional resources.

In Martin Javier's Game Changer report on "24 Oras," a group from Quirino High School has designed a microbial fuel cell powered by a combination of green water algae and poultry manure. 

The simple two-chamber setup can generate up to two volts of electricity, offering a budget-friendly and eco-friendly energy alternative.

"Isa isa pong chamber, doon po naiipon yung ating microorganisms na dala po ng ating organic matter at meron po ditong isang anode electrode kung saan po dumadaloy yung ating protons papunta sa isang external wire. Ico-connect po ito sa isang multi-meter para ma-record yung voltage and current na napo-produce po nito. Makakatulong po ito dahil budget-friendly nga po and makaka-less po yung negative effects ng electricity sa ating environment," explained student innovator Aliana Kyle Monforte.

(One chamber collects microorganisms from organic matter, and an anode electrode allows protons to flow through an external wire. The energy produced can be recorded using a multimeter. This method not only provides power but also helps reduce negative environmental impacts.) 

Meanwhile, at San Juan City Science High School, another young innovator has developed a homemade solar cell charger utilizing entirely recycled materials. This dual-purpose charger collects and stores solar energy efficiently.

"Dual purpose po siya pwede po siyang i-charge through solar, pwede po siyang kumuha ng energy through solar. Lahat po ng nandyan na materials is recycled," shared Kristine Faith Laurel.  

(It can be charged through solar power and repurposed for various appliances. The boost converter regulates voltage to prevent damage to electrical devices.)

These prototypes demonstrate that clean, renewable energy solutions can be achieved through resourcefulness and scientific ingenuity. More importantly, the students have demonstrated that alternative power sources can be both cost-effective and environmentally friendly, setting the stage for future green innovations.—Sherylin Untalan/LDF, GMA Integrated News
