The University of Kentucky Solar Car Team drove Gato del Sol III into the courtyard of the UK Engineering building in celebration of the solar car’s completion of the 2,400-mile North American Solar Car Challenge last week. The car traveled from Plano, Texas, to Calgary, Alberta, using only power generated by solar panels for fuel.
The UK solar car team is a student-led organization, with most of the design and construction of the car done by the students. Only a few of the car’s components were bought and or manufactured off-campus.
The car’s motor generates 2 horsepower at about 2 kilowatts, and it also acts as a generator when braking so that little energy is wasted. Top speed is estimated at 70 mph, although it has never been measured for sure because the faster you go, the more energy you waste.
The shell of the car is made of foam and fiberglass composite, making it light and strong. The vehicle has 474 solar cells and 364 batteries. The car runs on three wheels which gives it less aerodynamic drag and rolling resistance.
According to the team’s Web site, this was Kentucky’s first solar car to qualify and finish in the competition. The UK entry came in 11th at about 100 hours. The winning time, for the University of Michigan’s vehicle, was less than 52 hours. Oregon State University had the final finisher, at about 145 hours.
