Schneider Electric's "Go Green in the City" is a business case challenge inviting younger students to take a look at the current global energy situation, contribute possible solutions, and of course, learn in return.
This year's "Go Green in the City" resulted to 1,300 project proposals with only three making it to the finals: Angel Ed Ameril and Mycca Mae Valmonte (Polytechnic University of the Philippines) aka Team Young Innovators; Gabby Ozaeta and Yumi Briones (Ateneo de Manila University) aka Team Chinquapin; and Mary Cotoco and Seb Dela Cruz (De La Salle University-Manila) aka Team Brine Me Water.
Out of the three, Team Chinquapin’s idea to utilize rainwater and sunlight to make clean energy won above the rest.
The Project Rainshine by AdMU students Gabby Ozaeta and Yumi Briones uses a solar panel-like device that collects both sunlight and rainwater to convert it to clean energy. The panel is composed of two parts: a graphene layer to generate energy from raindrops and polycrystalline silicon solar cells for sunlight. As the solar cell generates electricity from sunlight, the graphene layer generates energy from raindrops making it possible to not only have solar power energy but rainwater as well, a truly useful device especially in the Philippines’ “come rain, come shine” weather.
The invention won't cost a fortune. Team Chinquapin estimated the cost of one Rainshine panel around 17,952php. One Rainshine panel can last up to 25 years.
On the other hand, Team Brine Me Water of the DLSU-Manila won first runner-up. They presented their TuBO System to ease the world's water crisis through the use of renewable resources. Team Young Innovators of PUP won second place for their Piezo On Wave Energy Reaping (POWER), a technology that uses the principle of piezoelectricity in harvesting tidal energy.
Team Chinquapin won the grand prize of 100,000php and will receive mentorship from Schneider Electric Philippines for the regional finals. The team will be representing the Philippines against country winners of Australia, Cambodia, Indonesia, Japan, Malaysia, Myanmar, New Zealand, Singapore, South Korea, Taiwan, Thailand, and Vietnam.
The search for clean and sustainable energy might just be in the younger generation's mind right now, waiting to be a lightbulb of an idea or a eureka moment. Let’s nurture it.
