Stem Education ‘Horizon’ | WIND TO HYDROGEN Science Kit
$ 420.00 excl. GST
► The Stem Education WIND TO HYDROGEN Science Kit enables students to invent their own clean energy applications using a small electric motor powered by a fuel cell.
• Hydrogen is produced through water electrolysis by a Reversible PEM Fuel Cell that is itself powered by a Wind Turbine with profiled blades based on NASA aeronautics.
• This Hydrogen is then converted to Electrical energy by the fuel cell and can be used to power a small fan.
• Turn wind power into hydrogen energy.
• Build your own Hydrogen fuel cell powered inventions.
Features:
• Revolutionary new Horizon Wind Turbine.
• Includes Horizon’s complete curriculum on renewable energy on CD.
• Demonstrate the principles of Wind energy, Hydrogen fuel cells, electrolysis and basic electronics.
Includes Full STEM Activity Materials for:
Changing number of blades | Changing angle of blades | Using different-shaped blades | Rotational dynamics | Reversible electrolysis reactions | Reaction rates | Renewable energy | Conservation of energy and energy transfer.
Experiments:
Electrolysis Mode Generating Hydrogen & Oxygen | Fuel Cell Mode Generating Electricity from Hydrogen & Oxygen | Determining the Minimum Water Decomposition Voltage | Polarization States for Hydrogen Fuel Cells | How Many Blades Are Best – 1, 2, 3 More? | Using Three Different Curved Blade Shapes | Using Blades You Make Yourself | Turbine Efficiencies | Measuring RPM | Tuning For Maximum Power | How Blade Angle or Pitch Affects Output Power | To Generate Hydrogen

WHY FUEL CELLS and HYDROGEN ?
► Fuel cells can be thought of as alternative energy devices.
They convert chemical energy into electrical energy.
Hydrogen fuel cells do this very cleanly, with no toxic emissions, and with a better efficiency.
Fuel cells do not generate energy out of thin air.
They use hydrogen.
Hydrogen is an outstanding carrier of energy.
► Hydrogen is non-toxic, renewable, easily obtained, and packed with energy.
When it combusts with oxygen, it turns into water.
This water can again be split into hydrogen and oxygen via electrolysis.
The generated hydrogen can be combusted once again, thus undergoing a limitless cycle without toxic emissions.
With a fuel cell, you can convert hydrogen into electric current without combustion.
Fossil fuels are converted into usable energy through combustion.
► The energy released during combustion is inherently difficult to capture and inefficient.
It also produces carbon dioxide, which cannot easily be converted back into a usable fuel.
A fossil fuel combustion engine at a power plant is only about 30 to 40% efficient.
This means it coverts only 30 to 40% of the energy in the fossil fuels to usable energy (electricity).
Engines in a car are even less efficient, and reach the level of 15 to 20% of efficiency.
Where does the rest of the energy go? It escapes as heat, vibration, and noise.
