The Fuel Cell Car & Experiment Kit has been a hot item since its introduction six years ago. It has captivated tens of thousands of children and adults alike, who have played and learned with it. Now, another version of the fuel cell car kit, the Fuel Cell X7, is available. This kit still has our award-winning model car with its unique reversible fuel cell not found in other fuel cell car models. The car still functions in the same manner as described on the opposite page.

The Fuel Cell X7 edition is designed to be accessible to more users, both in terms of content and price. The manual focuses more on building and designing a fuel cell car, rather than the comprehensive lesson on the science of fuel cells and solar cells found in the original version. The minimum age is lower and the instructions are geared toward a younger audience. The kit has been optimized for simplicity and ease of use over thorough experimentation. With its new focus, some parts have become unnecessary and have been removed to reduce the cost. The kit that is right for you or your child will depend on your needs, interest level, and age group.

The full-color, 16-page manual contains easy, step-by-step instructions for assembling and using the car, as well as scientific explanations. Ages 10 and up.

• assemble a working fuel cell car
• discover how fuel cells work
• use a unique reversible fuel cell
• learn about the potential alternative energies for automobiles
• learn about fuel cell car design

Ages 10+

Renewable Energy Science Kit

Build a working wind turbine to harness power out of thin air. Wind is one of the most promising sources of clean, renewable energy available today. Wind energy has been used for centuries to pump water and crush grain in windmills, and is now increasingly being used to generate electricity to power our modern world.

First, assemble a wind turbine complete with electric generator, adjustable rotors, and wind speed indicator. Then, conduct more than 20 experiments with your wind turbine, including experiments with different numbers of rotor blades, different blade angles and profiles, different wind speeds, different gear ratios, and so on. Use the wind turbine to generate mechanical power to lift a heavy weight or generate electricity to light up an LED and charge a rechargeable battery.

During the experiments, you will learn the physics of force and motion as it applies to wind power technology. Learn how to measure and calculate the different forces acting on the rotor blades by breaking them down into vectors.
Discover how the sun makes the wind, providing us with an endless source of energy. Read about different types of wind turbines and windmills.

The full-color, 32-page experiment manual offers illustrated instructions and scientific information. Ages 8 and up.

• build a working wind turbine
• harness mechanical energy to lift weights
• generate electricity to light an LED and charge a battery
• learn the physics of wind turbines
• discover how wind occurs and why it is such a promising energy source
