Ridgeblade Wind Turbine Silences Nimbys

Noiseless, Invisible, 9 times the energy, Low cost, Modular

RidgeBlade has been developed to be retrofitted into the existing built environment.
.. . In addition, the unit has been designed to be low cost, in terms of:
. . . . . . manufacture,
. . . . . . installation, and
. . . . . . maintenance.
Designed to use the existing roof area of a pitched roof,
. . . to collect and focus the prevailing wind,
. . . using the Aeolian wind focus effect.
This is where the wind is forced to travel over the roof surface, and
. . .. forms a pinch point at the roof ridge,
. . . accelerating the airflow though the turbine.
As a result, measured wind speed around the ridge,
. . . can be just over 3 times the actual wind speed.
Placing the turbine in this high flow area,
. . . means that up to 9 times the energy is available to it,
. . . compared to a HAWT (Horizontal Axis Wind Turbine) system.
The RidgeBlade uses advanced aerodynamics,
. . . to prevent noise in operation,
. . . whilst maintaining a low visual impact
. . . is also designed to self-limit the speed of the rotor,
. . . through its unique patented aerodynamic properties.
This means that the units achieve full capacity,
. . . at wind speeds of only 25mph,
. . . at this level of wind,
. . . the turbine speed achieves its maximum rotational speed, and
. . . this rotor speed is not exceeded,
. . . even in severe storm conditions.
The RidgeBlade has been successfully tested in over,
. . . 100mph winds in both wind tunnel and installed locations.
