Abstract
This study investigates the integration of thermoelectric generators (TEGs) into classroom chairs as a sustainable solution to the power limitations faced by students in Batangas City, Philippines, where charging infrastructure is often insufficient. As reliance on electronic devices for academic tasks grows, limited access to power outlets disrupts learning, affecting student productivity and engagement. The proposed PowerChair, designed to use TEGs to convert body heat into electrical energy, aims to provide an eco-friendly alternative to traditional power sources. This research assesses the feasibility, functionality, and power generation and sustainability of the PowerChair design by evaluating perceptions from mechanical and electrical engineers. Using a descriptive comparative research design, the study surveys 30 engineers—15 mechanical and 15 electrical—using structured questionnaires. Findings indicate that both groups agree on the feasibility, functionality, and power generation and sustainability of the PowerChair, with no significant differences in their perceptions. Based on the results, several design improvements are recommended, including integrating an energy storage component for a stable energy supply, incorporating a heat sink for cooling, exploring alternative converters to optimize energy efficiency, and implementing advanced power management strategies to regulate energy distribution effectively. These enhancements aim to improve the PowerChair’s performance and sustainability, while still aligning with the United Nations’ Sustainable Development Goals (SDGs), particularly SDG 7 (Affordable and Clean Energy) and SDG 9 (Industry, Innovation, and Infrastructure), and supporting the Philippines’ clean energy initiatives.
