more facts and information
To help you decide on which piece of machinery to use for your assessment, today you will be given some more important information on how these machines operate, how much fuel they use, and what types of fuel they use. At the end of today's lesson, you will need to decide which machine you will modify for your assessment.
combine harvester/header
Operation:
- Harvesters have GPS technology, however they are still operated by humans
- Harvesters have a "front" which is the part that chops the grain and sucks it into the "bin" storage compartment at the back of the machine. The front is powered from the Harvester and can not operate unless it is connected, as it does not have it's own power source.
- The cabin is air conditioned and heated
- Harvesters have Diesel engines
- The cost of Diesel varies from $0.90 - $1.20 per litre
- On average, a Harvester will use 60 litres per hour (approximately the whole fuel tank of a medium car, per hour!)
- Diesel emissions contribute to the development of cancer; cardiovascular and respiratory health effects; pollution of air, water, and soil; reductions in visibility; and global climate change.
cotton picker
Operation:
- Cotton Pickers have GPS technology, however they are still operated by humans
- Cotton Pickers use plastic wrap to roll the cotton into a bale. This wrap is not able to be re-cycled.
- The cabin is air conditioned and heated
- Cotton Pickers have Diesel engines
- The cost of Diesel varies from $0.90 - $1.20 per litre
- On average, a Cotton Picker will use 50 litres per hour (approximately the whole fuel tank of a small car, per hour!)
- Diesel emissions contribute to the development of cancer; cardiovascular and respiratory health effects; pollution of air, water, and soil; reductions in visibility; and global climate change.
Brainstorm:
Now you have all the information you need to select your machine to modify. Write down in your workbook which machine you have chosen, and brainstorm a few ideas as to how you could modify your machine and use renewable energy sources or change certain materials to make your machine more sustainable.
Next lesson will look further into which types of renewable energy would be most suitable for these machines, you can compare your ideas next lesson.
