Abstract: A pile (270) within a bore (110) comprises a column (250). The column (250) comprises a stack of a plurality of pile sections (300) arranged end-to-end within the bore (110). There is a cured material (260) between at least a part of an outside surface of the column (250) and the surface of the bore (110). The cured material, for example grout, may be provided through channels in the pile sections.

Abstract: A turbine generator having one or more wind turbines for generating energy and a series of plates located above and below each turbine for focusing and converging the wind inwardly. The plates are aerodynamically-designed to converge the wind onto the turbine and provide a strong wind current. The turbine generator is incorporated into a light fixture to provide self-sustaining light energy. Solar panels may be provided in conjunction with the turbine generator to provide an additional source of energy.

Abstract: A light fixture including a turbine generator having one or more vertical-axis wind turbines (VAWTs) for generating energy and a plate located above and/or below each turbine for focusing and converging the wind inwardly. The plate is aerodynamically-designed to converge the wind onto the turbine and provide a strong wind current. The turbine generator is incorporated into a light fixture to provide self-sustaining light energy. Solar panels may be provided in conjunction with the turbine generator to provide an additional source of energy and a controller is included to manage the flow of electricity and ensure that the light fixture is powered during periods of darkness.
