· Early windmills used an upright shaft, rather than a horizontal one, to hold the blades. This system was housed in a vertical adobe tunnel with flues to ch the wind (similar to a revolving door). The concept of harnessing wind energy via windmills reached Britain and Europe by 1137, where it underwent significant changes, with horizontal (rather than vertical) .

They depend mainly on the aerodynamic forces that develop when wind flows around a blade of aerofoil design. Windmills working on thrust force are inherently less efficient. So all the modern wind turbine blades are designed based on aerofoil section. Vertical axis wind turbines: It comes in two different designs. The savonius rotor; The darrieus rotor; savonius rotor: The savonius rotor ...

A vertical wind turbine has changed the notion of imagining windmills with blades rotating at horizontal axis. One can easily compare the rotation of a vertical axis wind turbine with a coin spinning along vertical axis. So, a modified configuration of blades and some good results can be obtained through vertical wind turbines. Still not as popular as horizontal wind turbines, the vertical ...

The vertical axis Darrius rotor is also a "lift" device, with its airfoilshaped "eggbeater" blades. The vertical axis wind turbine (VAWT) pictured above is a socalled "drag" propulsion device, along with equally strong "lift" components that allow the rim speed to be several times faster than the wind speed.

The vertical windmill sends to look like it came right out of a science fiction movie. The generator is at the bottom of the machine and therefore close to the ground. One advantage is that the generator should be easier to work on. Also the configuration makes the change of wind easier for the windmill to handle. Another good thing is that the blades spin slower, so it isn't a killing ...
