MOST people would think water and electricity don't mix, but a Northern Rivers company has come up with a clean, green, natural energy machine combining the two. The Aquanator, submerged well below the surface, works by capturing the kinetic energy of slow-moving but immensely powerful water currents using aquafoils to create mechanical energy. This mechanical energy is then used to power onshore alternators that generate electricity. The beauty of the system is that it captures free, constant energy and is non-polluting. The energy of the water current is captured with the propulsion of aquafoils which are harnessed to the drive system of an alternator via aqueous hydraulics. Requiring little more than a single anchor point on the ocean or river floor, Aquanators are anticipated to represent low levels of environmental impact and would be placed in areas where they would not represent a navigational hazard. Invented by Michael Perry and endorsed by his company Atlantis Energy Limited (AEL), the Aquanator will be able feed electricity into regional grids like the Gold Coast by the help of strong currents. "The Aquanator may well be part of an affordable, sustainable and credible solution," Mr Perry said. AEL have already entered an agreement with Country Energy to supply energy. A duplicate of the Aquanator will be displayed at Tweed City Shopping Centre tomorrow from 9.30am to 4pm with AEL staff on hand to answer questions.
