Some energy is wasted, depending on the angle
  of the blades, friction of the air and the sound
  energy that dissipates.

3.4 Practical Experiments at Ecolinc
A lamp is used to shine
light on a solar panel,
which converts light
energy into kinetic energy
and then into electrical
energy.
When light excites the
electrons in the ‘silicon
sandwich’, an electrical
current is produced,
which powers the buzzer
(sound energy), lamp
(light energy) or spinner
(mechanical energy).

  Solar panels have become more and more
  efficient due to developments in the
  technology over time. They need to be kept
  clean and usually have a “warranty period” of
  about 25 years.

  Water in a dam (or a tap in this case) is
  released to turn a turbine (with magnets and
  coils of copper wire) which creates an
  electrical current, which can be used to power
  lighting, heating and machinery.

B. Comparing Light Globes
Watts (W) ÷ 1000 = kilowatts (kW)

kW = greenhouse gas emissions
         (kg per hour)
Power (Watts) versus Light (Lux)
• Comment on the relationship between lux level,
  power of the globe and temperature of the globe
  in terms of energy efficiency.

• Is the amount of light produced by equivalent
  globes the same? Explain.

• Is there a significant difference in the energy use
  between the two types of globes overall? What is
  contributing to the difference?
C. Efficiency of Household Appliances
Household Appliances
For each of the following appliances list the
power output in watts and describe the
energy conversions that are taking place.
Some of the energy is converted usefully, but
some is dissipated or not converted usefully.
For example, this
fan converts
electrical energy
to kinetic energy
and has a power
output of 70W.
Some of the
electrical energy
is ‘lost’ as sound,
heat and
vibrations.
Hair dryer
Lamp with incandescent globe
Lamp with compact fluorescent globe
Portable fan heater
Electric kettle
Food Processor
Watts (W) ÷ 1000 = kilowatts (kW)

 kW = greenhouse gas emissions
             (kg per hour)
Household Appliances
• How could an energy meter be used in the
  home to help save energy?

• Comment on any results that surprised you.
  Are there any benefits or disadvantages with
  those results?
D. Passive Heating and Cooling:
         Power House
Did all temperatures
Increase at the same
rate?

How was the
‘greenhouse’ similar to
the Ecolinc ‘hotbox’?

How does the
‘greenhouse effect’ in
the atmosphere mimic
this model?
What happened to each temperature when the light was
turned on and remained on for a period of time?

Explain the circulation of air in the model house when
the temperature outside the glasshouse increases as it
would during the day.
Use a diagram and annotations to explain how passive
  heating and cooling occurs, as it does at Ecolinc.
   The model house and your results will help you.
E. Model Solar Car
“A solar cell is a diode (an electronic
switch element that only lets the
current through in one direction)
that directly converts solar energy
into electrical energy. The base
material of a solar panel is silicon
with boron or phosphorus added to
it, creating two layers in the silicon,
one with an excess of electrons and
one with a shortage of electrons.
When light hits the silicon, enough
energy is provided to cause the
excess electrons to flow to the other
layer. The electrons can only flow in
one direction. When the light lands
on the panel, an electrical potential
is formed which can be utilised.”
F. Model Hydrogen Car
           A battery provides the
           energy required to split
           water into hydrogen and
           oxygen gas using a
           ‘hydrogen cell’. The gases
           are stored in two tanks.

           When the gases
           recombine, they provide
           the mechanical energy for
           the wheels to turn.

3.4 Practical Experiments at Ecolinc

  • 1. Practical Experiments at Ecolinc A. Models of Renewable Energy Systems B. Comparing light globes Watts VS Lux C. Efficiency of Household Appliances D. Passive Heating and Cooling: Power House E. Model Solar Car F. Model Hydrogen Car
  • 2. Definitions: You need to know what the following terms mean: • Convection currents • Transmission • Absorption • Dissipation • Conduction • Radiation • Reflection • Infra-red and ultra-violet radiation • Electromagnetic spectrum
  • 3. A. Comparing Renewable Energy Systems Your Aim: To consider the advantages and disadvantages of each energy source including: • Amount of energy required to build the power stations (transport and construction) • Suitable locations • Cost (time, labour and financial) • Materials • Environmental limitations
  • 5. Here, a fan is used to turn a model wind turbine, which converts kinetic energy from the moving air into mechanical energy and then electrical energy for the light globe and the spinning colour wheel.
  • 6. Wind Energy Conversions Kinetic Mechanical Electrical Some energy is wasted, depending on the angle of the blades, friction of the air and the sound energy that dissipates.
  • 7. Wind Energy • Advantages • Disadvantages • Renewable • Not 24/7 • No greenhouse gases • Aesthetics produced from • Bird kills? operation • Expensive to construct • Minimal footprint (can • Not all locations are co-exist with windy enough to make agriculture) them viable.
  • 9. A lamp is used to shine light on a solar panel, which converts light energy into kinetic energy and then into electrical energy. When light excites the electrons in the ‘silicon sandwich’, an electrical current is produced, which powers the buzzer (sound energy), lamp (light energy) or spinner (mechanical energy).
  • 10. Solar Energy Conversions Light Kinetic Electrical Solar panels have become more and more efficient due to developments in the technology over time. They need to be kept clean and usually have a “warranty period” of about 25 years.
  • 11. Solar Energy • Advantages • Disadvantages • Renewable • Solar panels can be • No greenhouse gases expensive to make produced during and rely on finite operation materials (silicon) • Becoming more • Not suitable for all efficient locations and • Government rebates climates available • Not 24/7
  • 13. The model hydro-electric system transforms the energy from the moving water into electrical energy by using the water to turn a turbine (containing magnets and copper coils) which causes the The water turbine can create electrical current to power to turn on a lamp or run a flow. motor which causes the colour wheel to spin.
  • 14. Hydro-electric Energy Conversions Potential Kinetic Electrical Water in a dam (or a tap in this case) is released to turn a turbine (with magnets and coils of copper wire) which creates an electrical current, which can be used to power lighting, heating and machinery.
  • 15. Hydro-Electric Energy • Advantages • Disadvantages • Renewable • Not suitable for all • No greenhouse gases locations (need during operation mountains) • Can be turned on • Can affect habitats and off as required downstream. (given sufficient • Dams take up space water) for water storage.
  • 17. Watts (W) ÷ 1000 = kilowatts (kW) kW = greenhouse gas emissions (kg per hour)
  • 18. Power (Watts) versus Light (Lux) • Comment on the relationship between lux level, power of the globe and temperature of the globe in terms of energy efficiency. • Is the amount of light produced by equivalent globes the same? Explain. • Is there a significant difference in the energy use between the two types of globes overall? What is contributing to the difference?
  • 19. C. Efficiency of Household Appliances
  • 20. Household Appliances For each of the following appliances list the power output in watts and describe the energy conversions that are taking place. Some of the energy is converted usefully, but some is dissipated or not converted usefully.
  • 21. For example, this fan converts electrical energy to kinetic energy and has a power output of 70W. Some of the electrical energy is ‘lost’ as sound, heat and vibrations.
  • 24. Lamp with compact fluorescent globe
  • 28. Watts (W) ÷ 1000 = kilowatts (kW) kW = greenhouse gas emissions (kg per hour)
  • 29. Household Appliances • How could an energy meter be used in the home to help save energy? • Comment on any results that surprised you. Are there any benefits or disadvantages with those results?
  • 30. D. Passive Heating and Cooling: Power House
  • 31. Did all temperatures Increase at the same rate? How was the ‘greenhouse’ similar to the Ecolinc ‘hotbox’? How does the ‘greenhouse effect’ in the atmosphere mimic this model?
  • 32. What happened to each temperature when the light was turned on and remained on for a period of time? Explain the circulation of air in the model house when the temperature outside the glasshouse increases as it would during the day.
  • 33. Use a diagram and annotations to explain how passive heating and cooling occurs, as it does at Ecolinc. The model house and your results will help you.
  • 35. “A solar cell is a diode (an electronic switch element that only lets the current through in one direction) that directly converts solar energy into electrical energy. The base material of a solar panel is silicon with boron or phosphorus added to it, creating two layers in the silicon, one with an excess of electrons and one with a shortage of electrons. When light hits the silicon, enough energy is provided to cause the excess electrons to flow to the other layer. The electrons can only flow in one direction. When the light lands on the panel, an electrical potential is formed which can be utilised.”
  • 36. F. Model Hydrogen Car A battery provides the energy required to split water into hydrogen and oxygen gas using a ‘hydrogen cell’. The gases are stored in two tanks. When the gases recombine, they provide the mechanical energy for the wheels to turn.
  • 39. A Tour of Ecolinc – ESD features Ecolinc’s award winning building was designed using ESD principles. The building comprises energy efficient features such as: • natural cooling • ‘hot box’ heating technology • large, double glazed windows which allow natural light to enter while reducing heat transfer • low power lighting • solar hot water • solar panels which create electricity
