Reliability of floating foundation concepts for vertical axis wind turbines [PDF]
, 2010 Offshore wind turbines are developing at a rapid pace. By far the most common turbine configuration is the HAWT (Horizontal Axis Wind Turbine) and development of these machines is largely centered about drive train and blade issues with some work ...

ENERGY HARVESTING FROM COOLING TOWER BY VERTICAL AXIS WIND TURBINE (VAWT)
Jurnal Teknologi, 2015 In general, Malaysia is not a suitable location to harvest energy from wind. This is because Malaysia’s mean annual wind speed is low (less than 4 m/s) and inconsistent throughout the year. However, exhaust air systems which are usually installed in commercial buildings creates a uniform and consistent wind speed.

Small Wind Turbine Starting Behaviour [PDF]
, 2012 Small wind turbines that operate in low-wind environments are prone to suffer performance degradation as they often fail to accelerate to a steady, power-producing condition. The behaviour during this process is called “starting behaviour” and it is the
