Hydro-power from Coriolis Force Caused by Spin of Earth

After more than a decade of getting the cold shoulder from business and sceptical academics, Melbourne inventor and barrister Paul Kouris, 53, is on the cusp of commercially demonstrating his patented dream of generating green power from water vortices.

The precise physics may be unproven -- and according to some academics, it's impossible -- but Mr Kouris's determination to tap energy from the "Coriolis" force generated by the spin of the earth has now been backed by a $40,000 grant from Sustainability Victoria.

Traditional physical theory suggests that the fall of a body of water can produce only a fixed amount of energy, and the key to maximising that energy is to have a turbine operating as efficiently as possible. But Mr Kouris asserts that by adding a vortex -- the whirlpool we see running down our plugholes -- his turbine can increase energy generation by 5-25 per cent.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
