Horizon FCJJ Educational Renewable Energy Kits - Horizon FCJJ-40, The Horizon Educational Renewable Energy Box provides a complete understanding of how fuel cell technology interacts with renewable energy sources to create an entirely sustainable power grid. Demonstrating not only solar power, wind energy, and kinetic energy, the kit also presents the benefit of the incredible storage potential of a super capacitor. There's a range of supplied fuel cells for students to compare, including a PEM hydrogen fuel cell, the salt water fuel cells and a direct ethanol fuel cell module. All of the equipment included in this kit will enable countless experiments with so many scientific principles at work, and plenty of space for creativity.
