Definitions

• the current invention relates to turbines, particularly to extendible vertical wind and water turbines as well as mechanisms to raise and lower turbines supported on a mast.
• Wind power is especially attractive but wind turbines have one disadvantage due to the efficiency of the turbine is greatest when the rotor diameter is as long as mechanically possible and has an uninterrupted wind from great distances.
• the smaller household type of turbines are not deemed to be cost effective, as the fixed reduced rotor size reduces the electrical energy generated thereby and the installation and maintenance costs can be prohibitive too, cranes and other expensive machinery are used to lower and raise the turbines on the mast or provide height access.
• a turbine mast is a fixed structure that holds a vertical or horizontal axis turbine for energy collection.
• the masts commonly have a pivot point to lower the majority of the mast to allow access to the turbine or alternatively plant machinery is used for access on top of the mast.
• lifting aids such as hydraulic systems are required to lower the mast, as well as experienced operators, and a ground clearance equivalent to the height of the mast including the wind turbine-rotor and generator assembly installed on top of the mast.
• masts are constructed to differing heights & other tolerances to suit the site & environment.
• the Mast pivoting configuration adds to the cost of initial construction, while the fixed method requires height access equipment for periodical maintenance, adding to the running cost.
