Formatted abstract
This study was carried out in light of the current global warming debate. Alternate energies such as nuclear, geothermal, coal and renewable, have been analysed and discussed regarding emissions, efficiencies and feasibility. This report focuses on Wave Energy Generators (WEGs) and compares the different types to the WEG developed by IVEC Pty Ltd. Most WEGs utilise the head pressure caused by the changing height along the wave. Other WEGs use the velocity of the wave to pressurise air to be fed to a hydroelectricity facility on shore. The details of each design are discussed in further detail in Section 6. The WEG designed by IVEC was simulated in Matlab with altering inputs for wave length, wave height and wave velocity. Initial analysis revealed an increasing wave height would increase the flow rate of air to the turbine, thus increasing power generation. The extent has been recorded in the results section along with those for changing wave length and wave velocity. The easiest and most significant power generation changes came from changing the wave height. This report concludes with recommendations regarding alternate locations in Queensland, Australia and Globally. Locations in Queensland include Brisbane, Townsville and Cairns. This is because of the storm threshold values (see Appendix 9), the absence of tropical cyclones to damage the WEGs and the distance from township. Feasible WEG locations in the World include, southern Australia, New Zealand, South America, The United Kingdom and Greenland.
