The Impressive Evolution Of Vertical Wind Turbine Technology

Vertical axis wind turbines produced in the states -- such as those manufactured by PacWind, Cleanfield Energy, WindTerra, Helix and Enviro-Energies -- are generally roof mounted models that are ideal for homeowners. Designed to generate wind power in spite of very low wind speeds, they cost approximately $5,000 per kw installed and come with their own specially matched inverter. While this is definitely a nifty technology, imagine how it could be applied on a much larger and more impressive scale to significantly impact the energy needs of larger populations. Well, no need to dream anymore.

An unconventional aerogenerator wind turbine design invented in Great Britain by David Sharpe and developed by Wind Power Limited uses giant 120 meter high V-shaped composite wings to generate power. The Novel Offshore Vertical Axis (also known as Project NOVA) is England's great white hope for reduced energy dependence by the year 2020. With limited moving parts,  a low center of gravity for its generator and an overall insensitivity to wind direction, offshore installation of this energy generating behemoth is a lot more appealing than conventional horizontal axis wind turbine technology. Boasting simple maintenance, stable construction, environmental durability and radar friendly features, NOVA wind power structures are anticipated to be installed in offshore sites around the United Kingdom within the six years and generate an anticipated 1 gigawatt of wind power per unit.
