## Abstract

A linear network of wind turbine blade arrays has a plurality of wind turbine blade arrays. Each of the wind turbine blade arrays has a frame with a top structure and a bottom structure. The top structure is spaced from the bottom structure with first and second opposite vertical side structures. The top structure includes a top enclosure and the bottom structure includes a bottom enclosure. A plurality of shafts are spaced apart from one another along and extending between the top structure and the bottom structure. Each shaft is configured to rotate about a respective shaft axis within the frame. A blade formation for each shaft is arranged and configured to interact with moving air to cause rotation movement of the respective shaft. At least one generator is operatively connected to at least one shaft. The generator is mounted in one of the top enclosure and bottom enclosure.
