A wind power generation structure for a vertiport includes a takeoff-and-landing deck and a plurality of duct structures provided along an edge of the takeoff-and-landing deck. Each duct structure of the plurality may individually have a wind turbine and be individually rotatable in a vertical direction.

A support system arranged to support equipment such as electrolysers externally on a wind turbine. A hub encircling or coextensive with a tower or transition piece of the wind turbine surrounds a central vertical axis. The hub defines at least one docking bay having mounting formations to which a support module can be releasably engaged, thereby providing an equipment platform cantilevered from the hub. Where the hub comprises a plurality of docking bays spaced apart angularly around the central axis, a corresponding plurality of support modules are engageable with the hub in a petaloid arrangement. In plan view, the docking bays correspond with respective sides of a polygon. On installation, each support module is suspended on hook formations of a docking bay and is then pivoted into engagement with other mounting formations of the docking bay. The hub can be assembled from sections around the tower in a retrofitting operation.

The present invention is an energy storage system comprising a mechanical bellows having an outer flexible material casing with one or more functional elements that operate as actuators for expanding and contracting the outer flexible material casing to store or deliver energy.

A vertical-axis turbine extending longitudinally along an axis of rotation is disclosed, wherein the turbine has first and second blades disposed around the axis of rotation, the first and second blades having proximal portions and distal portions located relatively close to and away from the axis of rotation respectively, and body portions located between the proximal portions and the distal portions. The turbine also has a rotor assembly coupled to an end of the first and second blades. The proximal portion of the first blade contacts the body portion of the second blade and the proximal portion of the second blade contacts the body portion of the first blade to form a closed volumetric region around the axis of rotation. The shape of the first and second blades may be defined by twisting a sheet of flexible material according to a frame comprising two or more pairs of battens.
