SSG Christopher Walker experienced the loss of both arms, his left leg, and many other injuries from an improvised explosive device in 2012. After recovery, he picked up woodworking but after nine years, his setup still does not accommodate a wheelchair amongst other limitations. To increase safety, capability, quality, and speed, Team Benchwarmers created: a height-adjustable bench that allows sitting and standing, shelving for better tool access, a crane lift to move material, and an arch arm to safely manage cords.

A Vertical Axis Wind Turbine (VAWT) has its axis of rotation perpendicular to the wind streamlines, i.e., vertical to the ground. Thus, it has a drag side which rotates against the wind, and the lift side which rotates in the direction of the wind. In this project, the team built a VAWT in such a way the flexibility of the blade reduces the drag on the upstream side while it increases the lift on the downstream side. The task of this project is to compare the efficiency of traditional rigid blades to new flexible blades for VAWTs.

The goal of this project was to compare the performance of a GPS solar panel to a stationary panel with a reflector. This was achieved by creating a platform support system for the solar panels and reflector as well as designing the reflector to amplify the sunlight onto the stationary solar panel. The team manufactured a platform to raise the GPS solar tracking system above ground, which will allow the tracking system to position the panel perpendicular to the sun to obtain maximum sunlight and avoid shadows. Additionally, the team manufactured a reflector that can be manually adjusted to maximize energy collection. The successful completion of this project will provide important insights to solar energy research and help revolutionize solar energy production and implementation.
