Solar Car Engineering
How can we design and build an energy-efficient solar car to reduce environmental impact?
Yuri wants to understand how mechanical, electrical and computer engineering fit together, and cares about clean technology.
Plan: Build a mini solar car first to learn the mechanics and electrics, then a full drivable one.
Test a hypothesis: Wired a solar panel to a DC motor on a breadboard. In partial sun the motor didn’t turn; in full sun it ran.
Build: Assembled the gears, shaft and chassis, with photos of each stage.
What went wrong
The motor kept shifting between the Lego parts.
Next step: Added blocks under and around it to hold it steady.
Where it stands
The finished mini car travelled 3 m in 4 s in strong sunlight, an average of 0.75 m/s.
