Arizona State University
"Desert Ray" Solar Vehicle
SOLD! ($2,500 on 11/15/01)

This vehicle was designed and constructed for competitive solar vehicle racing by the students and faculty of Arizona State University. Since focus was shifted to newer vehicle concepts, the Desert Ray is without a photovoltaic array, solar trackers, or batteries. The vehicle, however, is in perfect working order. The highly-efficient electric drive performs well, and makes the vehicle a very capable battery-driven electric vehicle, with the availability of becoming a solar vehicle yet again with a few additions.
