A system for assembling a tower section of a lattice tower structure for a wind turbine may generally include a tower assembly fixture having a plurality of radially extending fixture arms, wherein each fixture arm extends between a first end and a second end. In addition, the system may include a plurality of trolleys. Each trolley may include a base frame configured to be coupled to one of the fixture arms between its first and second ends and a leg mount pivotally coupled to the base frame. The leg mount may be configured to be coupled to a bottom end of a support leg of the tower section such that, when each of the support legs is coupled to its respective leg mount, the support legs are supported above the tower assembly fixture at a substantially vertical orientation.

A wind operated electrical power generating system integrating a wind powered turbine with an electric power generator. The generator is capable of outputting a power level that is greater than a power level obtained by the turbine when the system is operating at an operational rotational speed. The power output is optimized by increasing a load upon the generator. The optimization is based upon the rotational speed of the elements of the system. The system adjusts the load applied to the generator as the system meets each of a plurality of predetermined rotational speeds. The load adjustment can be provided by manual or automated intervention. The system can integrated the generator directly within the turbine or remotely. In a remote configuration, a hydraulic pump obtains power from the turbine and transfers the power by flow of hydraulic fluid to a hydraulic motor. The hydraulic motor drives the generator.

A system (1) is described for generating electric energy by exploiting wind at a height, comprising at least one ultra-light component of the kite type composed of two or more retractable wing profiles (11, 12) which can be extended or retracted through means placed inside a central housing (13), thereby obtaining both the chance of more easily rising and descending the kite, and the chance of regulating/controlling the working surface of the wing profiles (11, 12) depending on a wind intensity.
