Stem Education ‘Horizon’ | WIND ENERGY Science Kit
$ 321.00 excl. GST
► This Stem Education WIND ENERGY Science Kit aids to build a miniature power generation system that converts Wind into Electrical energy.
• Experiment with the pitch (angle setting) of turbine blades and find out the optimum number of blades for generating electricity.
Features:
• Nine blades, with three types of profiled blade based on NASA aeronautics and one type of poly-propylene sheet blade, provide the opportunity to find the perfect balance of wind resistance, weight and angle.
• Uniquely designed blade profile based on NASA aeronautics.
• Most realistic wind turbine experimentation available on the market.
• Complete wind energy curriculum covering vertical and horizontal axis turbines.
• Blade angle adjustable from 0° to 55°. (3 positions).
Kit Contents:
Wind Pitch turbine body | Rotor head for profiled blades | Profiled blades for turbine | Rotor head adapter for sheet blades | Polypropylene sheet blades for turbine | Rotor unlocking tool | Turbine Support base | Aluminum wind turbine post | LED Voltmeter/Music Maker Module | Reversible PEM Fuel Cell | Reversible PEM fuel cell base | Hydrogen and Oxygen tanks | Inner Gas containers | Water-gas tank module base | Transparent Silicon tubing | Flexible 2 mm banana connecting leads | Plastic plug pins for fuel cell | Battery | Connecting leads | Motor with fan propeller blade | Assembly instructions | CD-ROM with curriculum manuals.

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.
