This fuel-cell science kit demonstrates the real possibilities of how hydrogen can be used as a 100 percent clean fuel for cars in the future. The car can steer independently of the user once in operation: When the car hits a barrier, it will automatically find its way by reversing and turning 90 degrees. A user manual makes the car kit easy to construct and operation only requires 2AA batteries and water. Solar panels can also be used and are available as an option. The science kit contains a fuel cell, a car chassis, a small electric motor, two water and gas storage containers, cables, tubes, a plastic syringe and a user manual.

Horizon's iconic H-racer refuelable fuel cell car has entered the second generation, with infrared remote control and steering capability, as well as faster driving speed due to a new generation of miniature PEM fuel cell. Launch date: October 2008.

This clean-energy set created for use at home or school uses fuel cells and allows kids to learn about wind energy as well as create hydrogen using wind and water; thus kids make their own scientific demonstrations. The set includes a water/gas storage module, a reversible fuel cell, a miniature wind turbine, an electric motor, a propeller blade and a manual. Launch date: Fall 2008.

Bio-Energy Kit is the world’s first fuel cell kit that runs on a mix of plain water and alcohol. It is a simple educational product used to introduce a new generation of fuel cell technology to students, aspiring scientists, teachers and engineers, investigating new power possibilities for consumer electronics.

The miniature hydrogen fuel cell car fits in the palm of a hand. The battery-less car operates on a fuel cell that is powered by its own on-board hydrogen storage system, ensuring it an unlimited supply of clean energy. Simply adding water to the station’s tank will create hydrogen fuel at the flick of a switch.

This scaled down version of a clean energy experiment demonstrates the inner workings of a renewable energy system. Its modular quality allows users to learn the system step by step, customize the way the system works, and visually observe the system from start to finish.

The set includes a solar cell, a PEM reversible fuel cell, a motor and oxygen and hydrogen gas containers. This easy-to-use kit requires only water to create hydrogen and generate electricity, making it perfect for science labs, classrooms, homes and demonstrations.

This space-age-looking follow-up to Horizon’s H-Racer fuel-cell toy uses the next generation of “polymer electrolyte membrane-base fuel cell” to power it to fast-driving fun. Yet another demonstration by Horizon of the shape of fuel to come, the Hydrocar’s new technology operates at a lower temperature and lower pressure than previous fuel cells, making it a safer technology if it were to be used in full-sized automobiles (or neighborhood energy infrastructures). Since this little car only turns after it bumps into things, it’s probably a good thing it’s not going to go all Hindenburg on us.
