SPARROW was my entry into the Local Motors Terra Prix 2085 Competition. The challenge was to design a race vehicle and a support craft for it to race across the world in the year of 2085. My solution was a racer that's powered by two truly sustainable energy sources - sound and heat. It translates any sound around the vehicle into electricity that powers the wheels. It takes any heat created by or around the vehicle and uses that to energy to operate a Tesla steam turbine that generates more electricity.
