The present invention relates to a novel way of manufacturing and assembling wind turbines to harness energy from wind. Chiefly, the invention is a way to build a darrieus vertical axis wind turbine and eliminate the need for a tower. This is done by using greater than two blades, replacing the tower with high tension cable(s) and adding high tension cables to the circumference of the turbine attached to each blade. This prevents deformation, reduces weight, and makes a rigid structure using tension and compression. Furthermore, this turbine can be built from whole bamboo poles and includes blades composed of whole bamboo poles, cables, and architectural fabric/membranes/composites.

Resumen de: US2020392946A1

A self-aligning to the incoming wind floating platform supporting multiple wind turbines (17, 18) forms a wind power generation unit. Under horizontal wind, the wind load resultant passes the center of geometry (or “C.Geo”) of the wind load receiving areas of the floating platform, but not the turning axis (15). This results in a yaw moment about the turning axis (15) to turn the floating platform, until the wind load resultant simultaneously passes through the C.Geo and the turning axis (15). A wind park or wind farm may include at least one of these floating platforms that are capable of self-aligning to the incoming wind for electric power generation. The floating platform helps reduce the length of a submarine power cable (44) of the platform, hence reducing electric resistance and subsequently heat loss, thereby reducing the cost of the submarine power cable (44).
