Its that time of the year again. Teams from around the world flock to a small town in Nevada (near the salt flats) to try their vehicle in a challenge to set the human-powered speed record. This is the final test for the vehicle we have built this summer. Upon arriving, the vehicle was nearly complete. Saturday and Sunday, we have been testing out the stability of the vehicle to make sure it is rideable (with only 4 degrees of steering, this was questionable). Sure enough, our design was sound and Todd, Calvin and Trefor quickly got the hang of the tiny amount of steering.

A lot of what it takes to go break the world record at Battle Mountain is the efficiency of the external aerodynamic shape. A huge amount of work had been done to design and optimize the shape of Eta prior to the start of summer to ensure we get the least drag on the vehicle. In this post we will outline the steps we went through in the design process.
