Why use Contra Rotating Vertical Axis Wind Turbines?

Operates in low winds and doubles the output of conventional wind turbines (Horizontal Axis Wind Turbines HAWTs).
Reduce wildlife mortalities over conventional wind turbines.
Low noise and small footprint allow high density of turbines near existing infrastructure.
9 x better reliability than a conventional generator.
Low stress blades in VAWT configuration ensures increased service life and reliability.
CR VAWT will have more than double the service life to current HAWTs!
CR VAWT blade manufacturing process will significantly lower the manufacturing waste, cost and time needed to manufacture turbine blades.

And why have CR VAWT arrays on buildings in the Cities?

CR VAWTs emit little to no noise which allow high density of turbines on or near existing infrastructure and populated areas.

VAWTs can be built as a cluster on a supporting framework similar to cell towers (image below)

CR VAWTs are great on buildings as the wind accelerates over structures making Turbines more efficient (image below)! And being sited near population centres offer the lowest infrastructure cost, the lowest resources use, the lowest visual impact and the least harm to all of earth's creatures!

Why have CR VAWT arrays on Cell Phone Towers?

A small array on each tower can be fitted during construction, or retrofitted and can completely offset the 129MW of electricity per hour or over 1TW per annum consumed by the 25,892 towers currently in use in Australia!

The array pictured below peak at 15kWh and can feed excess energy back into the grid and the blade's composite materials don't interfere with Cell Phone Signals!

Why have CR VAWT arrays on semi-submersible wind farms?

The 2 maps below help illustrate why off-shore CR VAWT wind farms near population centres offer the lowest infrastructure cost, the lowest resources use, the lowest visual impact and the least harm to all of earth's creatures!

CR VAWT’s patent pending, reliable, compact and easily deployed Contra Rotating Vertical Axis Wind Turbine (CR VAWT)

CR VAWT patent pending blade manufacturing process will significantly lower the manufacturing waste, cost and time needed to manufacture turbine blades.

CR VAWTs are omnidirectional, that is, they do not change orientation to match the wind direction as HAWTs must do.

CR VAWTs feature a direct drive (no gearboxes), that significantly increase efficiency, and reduces the number of working parts, down time and operating costs.

FARSTE DRIVE’s PCB generators are 9 times more reliable than a conventional electric motor/generator.

Vertical axis wind turbines (VAWTs) can handle turbulent and unconventional wind and generate energy at slower speeds.

VAWT noise levels of less than 40 dB at a distance of less than 6m, while HAWT’s are more at much greater distances.

CR VAWTs can be sited within the easement of the existing power grid, highways, rail corridors or offshore. Thus negating the need for further land clearing or energy grid enlargement.

CR VAWTs are fully scalable from a 500W camping model, or 10kW home install through to giant 4MW mega generators!

CR VAWT have 40 years experience in Engineer (Design), Procure, Construction and Maintenance who can provide you with a turn key Wind Turbine solution to suit your circumstances.
