Wind Turbine Blade Engineering with Recycled Materials

Project Summary

Students at Chester Area School designed and tested wind turbine blades using different recycled materials to learn about renewable energy and maximize electrical output.

Detailed Story

This hands-on engineering project engaged students in exploring wind power technology by designing and building their own wind turbine blades using recycled materials. Students tested three different materials—cardboard, balsa wood, and styrofoam—to determine which performed best for generating electricity. The project incorporated elements of scientific inquiry, as students experimented with different blade shapes, angles, and designs to maximize electrical output measured in volts. The competitive aspect of the project further increased engagement, with students eager to see whose design could generate the most power. One student, Krayton, observed, “I had the best angle, which made my blades turn faster!” This insight highlighted the importance of both blade shape and angle in optimizing performance. Throughout the project, students collected and analyzed data on their designs, which was recorded in spreadsheets for further analysis. The classroom setup included box fans to create consistent wind conditions and voltage meters to measure the electrical output of each design, allowing for fair comparisons between different prototypes.

Impact Statement

24 students gained hands-on experience with renewable energy technology, developing engineering design skills and scientific inquiry methods. Students learned about the key variables affecting wind turbine efficiency through experimentation and friendly competition, while also understanding the potential of renewable energy sources through direct engagement with the technology.
