Mining provides us with minerals, metals and other materials we use every day and the fuel used to generate electricity. These minerals have economic value and can benefit mankind.Although in Australia, less than 1% of the land is mined, depending on the size of the mine, method of mining and location, mining can have a significant impact on the environment. To minimise the effects of this impact, careful planning, management and supervision are required.
Designed for physics and engineering technology teachers, the unit Giants that walk the Earth is based around the physics of draglines. The physics that govern the operation of these massive machines provides an ideal context in which to investigate a life application specifically of the principles of electromagnetism.Images, diagrams, specifications and technical drawings are provided in a series of PowerPoints to explain how electric motors in draglines work, how the walking feet operate and how the processes of supplying power and moving various components such as the bucket and beam are achieved.
This comprehensive Giants that Walk the Earth PowerPoint provides a study of the dragline; the largest piece of machinery in operation in Australia. All year levels will benefit from the introduction with the latter sections more suited to the senior years of Physics and Engineering Technology.
A general introduction to the 'Powering the Future' forum conducted April 12, 2010 at the Brisbane PowerHouse. Matthew discusses the role of gas (and LNG) in the overall energy mix, the role of gas in reducing carbon intensity, structure of gas-fired electricity turbines and a brief overview of some renewable technologies.
The Callide Oxyfuel Project is a world-first demonstration of oxyfuel technology, where a conventional coal-fired power station boiler is fired with oxygen and exhaust gas as instead of regular air. This results in a more concentrated stream of carbon dioxide that can be captured and stored.Chris Spero, Manager Emerging Technology/CS Energy Callide Oxyfuel Project Director, provides a brief overview of low emission technologies, oxyfuel combustion in particular and then outlines the progress of the oxyfuel project at Callide and the projected timeline for completion.
This is a teaching unit, designed for Year 10, aimed at engaging students in investigations about low emission energy sources. A unit outline, teacher guidelines, student activity and an assessment task are provided.
Find out how carbon emissions from power generation can be reduced. This is a PowerPoint presentation that deals with the contribution carbon capture and storage can make toward reducing greenhouse gas emissions. It explains the carbon cycle and the greenhouse effect. Techniques of carbon capture are described and their advantages and disadvantages outlined. Geosequestration is illustrated, and present as well as potential sites for carbon storage are identified. Most slides have images, flowcharts or maps and teachers notes are included.
In this interactive diagram, students learn how a power station works. Students build the coal fired energy plant by dragging images into the correct position and in the correct order, then select captions to match.
