Wave power in Australia

Wave power in Australia is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wave power in Australia rather than just read about it. In short: Wave power in Australia is being developed as the country has a long and largely deep-water coastline. It is one of several regions of the world where wave power projects are being considered.

Key takeaways

Wave power in Australia belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wave power in Australia to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wave power in Australia from memory before moving on to harder problems.

Reference excerpt

Wave power in Australia is being developed as the country has a long and largely deep-water coastline. It is one of several regions of the world where wave power projects are being considered. Australia has great potential for wave energy because strong Southern Ocean winds generate consistently large waves ideal for wave energy production. The main challenges are capital cost and withstanding damage from harsh ocean conditions.

Projects In early 2015 the Perth wave energy project was commissioned. Ocean Power Technologies (Australasia) is developing a 19 megawatts wave power station connected to the grid near Portland, Victoria. The project has received an $66.46 million grant from the federal government of Australia. Oceanlinx is trialling a wave energy system at Port Kembla - Thousands of air filled balloons are submerged under water and energy is collected by the changes in the depth of the water column changing the pressure in the balloons. A wave power project is being developed at Douglas Point, South Australia. BioPower Systems are developing their bioWAVE system anchored to the seabed that would generate electricity through the movement of buoyant blades as waves pass, in a swaying motion similar to the way sea plants, such as kelp, move. It expects to complete pilot wave and tidal projects off northern Tasmania this year. Inside Western Australia, Carnegie Wave Energy are refining a technology called CETO, which uses energy captured from passing waves to generate high-pressure sea water. This is piped onshore to drive a turbine and to create desalinated water. A series of large buoys is tethered to piston pumps anchored in waters 15 to 50 metres (49 to 164 ft) deep. The rise and fall of passing waves drives the pumps, generating water pressures of up to 1,000 pounds per square inch (psi). Carnegie's first commercial wave farm is due to be completed on Garden Island, near Perth, Western Australia, by mid 2014. Wave Swell Energy installed a trial wave generator unit in the harbour at Grassy, King Island. It is a 200 kW unit which is connected to the island's existing microgrid, which also utilises like wind, solar, battery and diesel. The trial was a success. It had an average conversion rate of 48%.

Worked examples

Example 1 — a first encounter with Wave power in Australia

Start with the simplest possible case. Write down what Wave power in Australia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wave power in Australia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wave power in Australia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wave power in Australia

In research: Wave power in Australia appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wave power in Australia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wave power in Australia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Renewable energy in Australia, Wave power by country, so understanding it makes those chapters shorter.
In everyday life: Look for Wave power in Australia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
