Using the Coriolis force, the turbine is designed to harness draining water’s rotational kinetic energy, as distinct from traditional hydroelectric plants which get their motive power from water falling under gravity’s influence.
The funding comes after tests conducted by the University of Ballarat, Australia, which showed that the vortex effect did indeed produce additional power beyond that provided by only the gravity-fall of water. Kouris claims that his 2004 small-scale test tank installation managed to extract an additional 27 percent energy over what is produced by traditional turbines. If his figures are correct, refurbishing existing hydraulic installations with the new turbine could radically increase their power output capabilities.
Kouris filed for a patent in 1998, but a stoush may be brewing with Austria where the town of Obergrafendorf has had Coriolis turbines operating in concrete ponds on the banks of a river since 2005.
