Paul Kouris

Mr. Kouris was born in 1955, is a Barrister, and was admitted to the Victorian Bar in 1981. He is a Member of The Royal Society of Science (Vic) and of The Australian Institute of Energy.

The idea for the “KOURIS ‘CENTRI-TURBINE’ GENERATOR” came to Mr. Kouris while he was completing his education in Law/Philosophy in the mid-1970s.His Eureka moment occurred whilst observing water spiraling down the sink. This was the time of the Arab Oil Embargo (OPEC) and the resulting energy crisis. It was also a time when the potential dangers of nuclear energy production were becoming more well known.

Contemplating the problem and seeking a possible solution, he one day conceived the ‘Centri-Turbine Generator’ and how it could potentially be applied to improve the operation of hydro-generator systems.

A Brief History

  • 1975

  • 1998
    Vortex Turbine Patent Abstract
    In September 1998 the “KOURIS CENTRI TURBINE GENERATOR” received a Notice of Allowance for Letters Patent in the U.S.. The U.S. Patent was subsequently granted and published by the U.S.P.T.O. on 5th September, 2000.
  • 2004
    In 2004, the first proof-of-concept KCT turbine was installed and tested in Kalorama, Victoria. The unit had a 2m diameter vortex chamber, and produced 183W.
  • 2008
    The first demonstration KCT unit is installed in Marysville, Victoria. The unit has a 2m diameter and produces enough electricity to power a conventional home, over 500W (12kWh/day) using only 110L/s, with a fall of 60cm.
  • 2012
    Mark2 Transportable launch
