The ABC has a report today noting that Wilson "Ironbar" Tuckey is still promoting his vision of large scale tidal power generation in the Kimberly region in Western Australia.
The Federal Government expected to release their white paper on Australia's future energy needs next year and the use of tidal power in the Kimberley is expected to be one of the options under consideration.
There are renewed calls for the development of renewable energy in the Kimberley, with the federal Member for O'Connor spruiking the merits of tidal power. Wilson Tuckey wants the Commonwealth to spend $10 billion establishing the necessary infrastructure for a tidal power industry in the region.
Mr Tuckey says tidal energy could provide 10 times the country's current electrical capacity without producing any carbon emissions. He says the Commonwealth should fund start up infrastructure before commercial interests jump on board like the State Government did with the North West Shelf. "This will be the same. If the Australian Government puts in the original tidal generating capacity and the interconnecting transmission lines, which is probably the most important, the Kimberley will then see a rash of people charging in to produce that same electricity from other localities," he said.

In 1870, in Twenty Thousand Leagues Under the Sea, Jules Verne wrote: "I owe all to the ocean; it produces electricity, and electricity gives heat, light, motion, and, in a word, life to the Nautilus."
Indeed, the Earth has an enormous natural solar collector - the tropical oceans. "On an average day, 60 million square kilometers (23 million square miles) of tropical seas absorb an amount of solar radiation equal in heat content to about 250 billion barrels of oil."(1) Energy "equivalent to at least 4000 times the amount presently consumed by humans."(2) If we can tap into this renewable source, considering thermodynamics and entropy, approximately 1% of it could provide the entire current worldwide demand for energy. More than enough energy is available, we only need a way to get it - in a practical, cost effective, ecologically safe and sustainable way.
Ocean Thermal Energy Conversion (OTEC) is a technology that can extract useful work from solar energy stored in the sea. Since the sea IS the energy storage medium, OTEC offers 'always on' baseline supply -- during bright clear days and dark nights, in still air and ferocious wind storms -- without the expense and complications of artificial energy storage systems.
