Gorlov Helical Turbine

March 3, 2008

The Gorlov Helical Turbine (GHT)developed by Alexander Gorlov, a Russian civil engineer, is a newly developed technology that provides a reliable source of electricity by extracting kinetic energy form flowing water.

 Whats most important is that GHT is not as expensive as wind or hydro turbines. Also, has great advantages:

  • No flooding from dams
  •  Minimal obstructions of water flows
  • Reliable
  • Low cost, etc.

It is a great alternative!  Take a look at this example:

 Project Goal: Use Tidal Energy to generate electricity.

Scenario: In the amazon, rural residents are not able to access power lines due to their locations. The only options available to the are solar panels and diesel generator.

 Equipment Needed:

The Helical Turbine rotates on a shaft with a pulley that runs an alternator by means of belt. The alternators chargers batteries when used off the grid.

Results:

  • Accessible Technology
    • About 90% of Tide Energy stations can be built using locally available labor, materials, and equipment.
    • Only the technically refined helical turbine blades are outside components

Benefits:

  • Sufficient to meet basic need of 10 households.

Biotech Crops
