1. SOLAR POWERED VEHICLES Morgan Stelli

2. HOW THEY WORK  Solar cars harness energy from the sun, converting it into electricity  That electricity then fuels the battery that runs the car's motor  Instead of using a battery, some solar cars direct the power straight to an electric motor.

3. SCIENCE OF SOLAR PANELS  Solar panels work because of photovoltaic cells (PVC)  PVCs convert the sun's energy to electricity  Made up of semiconductors, usually silicon, that absorb light  Sunlight's energy frees electrons in the semiconductors, creating a flow of electrons  That flow generates the electricity that powers the battery or motor

4. Tokai Challenger The 2009 winner of the World Solar Challenge, held on a 1,864-mile course in the Australian desert outback. It had an average speed of 63 mph
