The AN-400™, the first of the AN series, is a shallow water turbine which has been extensively tested, and grid connected in Australia. The turbine uses Aquafoils™ to capture momentum from the flow of water to drive a chain perpendicular to the flow. The turbine is robust and can withstand water flow containing significant debris. It is fully scalable and has been developed over a 6 year period with multiple tow-testing and continual optimization. Tow testing of the AN-400 was carried out in July 2008 with impressive results verified by Black & Veatch.
