Build an effective wind turbine that can generate the most amount of power. This turbine should also be able to outstand extreme wind conditions (the fan) and well built enough to not decay.
Test multiple different types of materials in different ways to get the best possible outcome. This consists of the use of balsa-wood, cardboard and styrofoam.
Our team concluded that the use of a balsa-wood and cardboard mix blade gives our team the best results with the angle 15 degrees.
