Hi Angleo/Titan,

To be honest, I was never too interested in working with cars. Then, when I was working at a science museum, I had the chance to play with a model solar-powered cars. There were a couple of different designs of cars, so a friend and I would race the cars to see which was faster. We used a "racetrack" that started in the Sun and ended in the shade. The line between the Sun and the shade was the finish line. Because the cars were powered with solar panels, as soon as they crossed into the shade they would stop moving. It was fun!
