Use a open-loop pump system
Posted by Maarten Kanters to Equipment, 2009-10-27 14:26:47
A single pipe will transport seawater from each turbine base to the generator platform.
This makes the wind farm an open-loop system.
For conventional turbines, electricity is already generated in the nacelle. A system of gears and
a generator converts the power in the rotor shaft to electric power. The electricity is conducted
through a cable, along the base of the turbine support struct...
Fixed Pitched Blades

The blades will have a fixed pitch. This simplifies the design of the rotor significantly. Theoretically,
pitch regulation enables higher turbine efficiency at varying wind speeds. However,
advanced aerodynamic profiling of the blades will be applied to minimize the difference.
Installation vessels?

The investment costs of an offshore wind fields are high. Besides the investment costs these fields have to be maintained and eventually removed. At the moment it is not financially attractive for companies to build offshore wind fields without the government grants. Off course companies are inventing creative ideas to lower these costs.
25% Of the investment costs are the installation costs...
Aerodynamic Venturi-Wind Turbine Floater

The Dutch government has the target to install 6000 MW before 2020, which should be 20% of the energy use.
This means that in the Netherlands 1200 turbines of 5 MW should be installed, at the moment 230 MW is installed...
These turbines are around 100 meters high with rotor blades of 60 meter!
Ing. Jan. R. Hogervorst claims that the vision to fill the Noordzee with huge wind turbine farms ...
Innowind is shaping the future!

Reduced dimensions and increased efficiency, that is the way to go!
Is this the design of the future?
"It is worthwile to notice that any known windturbine does not exceed the maximum value of the coifficient performance predicted by Betz`Law.
But the INNOWIND Concept can lead to windturbines that exceed the maximum performance coefficient predicted by Betz`Law"
The concept claims:
- C...
