A wind turbine including a mast assembly having an upper support structure hingably attached to a lower support structure wherein the mast assembly has an installation position and an operational position. A wind turbine wheel is mounted to the mast assembly having a circular rim disposed at its perimeter and having an axle structure. An electrical generator is supported by the mast assembly and configured to engage with the turbine wheel for generating electricity in response to the rotation of the turbine wheel. A plurality of hydraulic lifts are provided in contact with the upper support structure when the mast assembly is in the installation position and configured to transition the upper support from the installation position to the operational position and wherein at least one hydraulic lift loses contact with the upper support structure during the transition.

A fluid turbine comprises a rotor rotatable in use about an axis transverse to the direction of fluid flow, the rotor having a first part carrying a plurality of arcuate blades that may be arranged selectably in compact straight shapes or in arcuate shapes and a second part journalled in a base structure by two or more bearings.

A modular foundation includes a central portion and a plurality of legs non-rotatably secured to and extending from the central portion. The plurality of legs are substantially equally spaced apart from each other wherein each leg includes a proximal end and a distal end. A ballast support adapter is attached to the distal end of each leg wherein the adapter is configured to support one or more ballast plates such that each leg can be independently positioned for leveling the foundation and supporting the monopole in a vertical position. A platform supports the monopole and is pivotally attached to the central portion wherein the platform is configured to move from a vertical position to a horizontal position.

A method assembles a wind turbine in a non-vertical orientation. The turbine has a nested wind tower with a plurality of tower sections, including a first inner tower section radially inward of an outer tower section. Each of the tower sections has a wall with an inner surface and an outer surface. The first inner tower section has a connection interface at or near its bottom end, and the outer tower section has a counterpart connection interface at or near its top end. The tower has a friction reduction member configured to reduce friction between the first inner tower section and the outer tower section as the first inner tower section is extracted in a non-vertical orientation. The first inner tower section is extracted in a telescoping manner until the connection interface contacts the counterpart connection interface. The method also secures the connection interface and the counterpart connection interface together.

A system for providing access to a wireless communication network can include a plurality of renewable energy structures. Each renewable energy structure can include an electricity generation assembly, a telescoping support pole positioned to support the electricity generation assembly, and a wireless communication device configured to relay wireless communication signals between a host signal source and a client device. The electricity generation assembly can include a wind turbine assembly and/or a solar power structure. The wireless communication device can include a cellular telephone signal repeater and/or wireless internet equipment. Each structure can include a display, such as an advertisement, one or more benches, and/or a container. Each structure can optionally include a water purification system, one or more cameras, one or more lights, and/or one or more motion or voice sensors for activating or deactivating various components of the system. Each structure may be permanently installed or mobile.
