A floating wind turbine system with a tower structure that includes at least one stability arm extending therefrom and that is anchored to the sea floor with a rotatable position retention device that facilitates deep water installations. Variable buoyancy for the wind turbine system is provided by buoyancy chambers that are integral to the tower itself as well as the stability arm. Pumps are included for adjusting the buoyancy as an aid in system transport, installation, repair and removal. The wind turbine rotor is located downwind of the tower structure to allow the wind turbine to follow the wind direction without an active yaw drive system. The support tower and stability arm structure is designed to balance tension in the tether with buoyancy, gravity and wind forces in such a way that the top of the support tower leans downwind, providing a large clearance between the support tower and the rotor blade tips. This large clearance facilitates the use of articulated rotor hubs to reduced damaging structural dynamic loads. Major components of the turbine can be assembled at the shore and transported to an offshore installation site.

A photovoltaic panel mounting system utilizes rubber tires to anchor and position photovoltaic panels to face the sun and resist wind forces. The shaded interior cavity of the rubber tires physically and thermally protects electronics and batteries. The tires may be filled with soil, concrete, water, or aggregate to provide further ballasting, enabling a photovoltaic mount system to withstand high velocity winds. Telescoping conduits may house wiring for the system and allow for resizing and reshaping of the mounting system. The mounting system decreases used tire waste and provides low cost components and portability.

A system for covering (i.e., closing) various types of sites where waste is deposited comprises a composite of one or more geotextiles that are tufted with synthetic yarns and an impermeable geomembrane, which is comprised of a polymeric material. The cover can include wind-resistant textured synthetic blade-like elements, such as vertical filaments, secured over a low-permeable polymer liner backing. Advantageously, the system does not rely on piled-on weight to resist wind forces and the cover can be deployed over a large area with little or no ballasting or anchoring. Optionally, the cover includes vertical filaments attached to the liner to break the wind aero-dynamics on the exposed cover.
