In one way or another, almost every form of energy we use originates as energy from the sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the sun, and Earth’s weather systems sustained by the sun. Even the energy stored in fossil fuels originated as energy from the sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells.
By building five awesome models and conducting ten experiments with them, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. Start with a simple rover model that converts sunlight into a rotating motion and demonstrates the basics of solar technology. Continue your experiments by constructing increasingly complex models: a solar helicopter, robot, and bug. Finally, build a cool praying mantis model that moves like an insect and is powered by a solar cell. The models can also be powered by a battery, allowing operation in all lighting conditions.
The 48-page book offers illustrated step-by-step instructions for the projects.
