“Wind generators are not turbines, because there is no nozzle ring to direct any wind on to a series of turbine blades fixed to a shaft.” Renewable Energy in perspective: Solar and Wind power | Watts Up With That?

While I am here, you mention the word “turbines”, which you correctly use in relation to steam powered generators, with the high pressure steam raised in boilers being fuelled by coal, “biomass”, nuclear fission, or gas. Wind generators are not turbines, because there is no nozzle ring to direct any wind on to a series of turbine blades fixed to a shaft. They are simply propellers, and their simplicity may be part of the problem in gaining much useful energy from them. Far better, and more correct to refer to them as wind powered generators, or… bloody windmills, as I prefer.
