Students will be introduced to the concept of energy in its different forms through a range of demonstrations. These demonstrations will also introduce the concepts of energy storage, energy efficiency, energy conversion and sustainability. An overview is given of issues surrounding sustainable energy for future generations. The status and impact of present day sources of energy are covered, including the sustainability of fossil fuel reserves and the impact of pollution and greenhouse gas emissions on the environment. Students will explore issues of resource sustainability by participating in the "Virtual Survivor" online game. Energy efficiency, as an important way to conserve our natural fuel reserves and reduce environmental and financial costs, is covered. Building design, appliance efficiency and other issues related to the smart and efficient use of energy are covered. Trends in the renewable energy industry are considered. An overview is given of renewable and nuclear energy sources, their harnessing and their conversion into electricity via various technologies. In particular, an overview is given of solar cells and their applications with emphasis on visual presentations and interesting case histories, including some fascinating mistakes and disasters. One lecture each week will be given by guest lecturers who are experts from industry, end-user groups, research, and government. The interesting area of "solar cars" is considered in detail as an example of a high profile application of photovoltaic (PV) devices and systems that deals with state-of-the-art technology. Students will explore issues in the design and racing strategy for solar cars by participating in the "Virtual World Solar Challenge" solar car race from Darwin to Adelaide. Students will also explore the design and fabrication of silicon solar cells while working as engineers on the "Virtual Solar Cell Production Line".
