Abstract: An electrical power producing wind turbine eliminates the possibility of being struck by lightning, reduces the complexity of gear trains and simplifies maintenance at heights. The wind turbine is electrically isolated from ground to reduce the possibility of being struck by lightning and the generator is located at ground level to simplify maintenance. The turbine blade shaft is directly attached to a hydraulic pump. The hydraulic fluid is transmitted to ground level through dielectric tubing and acts both as an electrical isolating medium and a transmitter of mechanical energy to the generator located at ground level. The wind turbine blade, shaft and hydraulic pump are electrically isolated from the support structure at the upper end.
