"A method for extracting energy from a flowing fluid, and together comprising a device for extracting energy from a flowing fluid". A method relating to an assembly by which energy can be extracted from a flowing fluid. It is proposed to consider all assembled devices in the set as a flow mass. Particularly those devices on the upstream side of the assembly are so arranged that they exert lateral (horizontal and / or vertical) forces on the fluid flow, as a result of which flows are produced that guide fast fluid through the energy extracting devices and guide slow fluid precisely out of these (in certain cases precisely the reverse is also advantageous). In particular, this set consists of a wind farm and lateral force generating devices are a type of vortex generators for the atmospheric boundary layer, more specifically they constitute horizontal or vertical wind turbines positioned at an inclination to the wind. By systematically arranging devices to certain standards, production can be increased by the fact that, first, part of the slow air at the bottom of the atmospheric boundary layer has already been moved away before the wind hits the farm, and secondly , because the trailing air from the energy extracting devices is taken away by the circulations and is replaced by the fast air from a higher altitude. A number of advantages are obtained by virtue of the invention. For example, the fluid velocity at the location of the energy extracting devices is higher in many cases as a result of which higher throughput is obtained. In addition, energy extracting devices are harmed to a lesser extent by air trails and they can therefore be arranged closer together as a result of which the cable length is saved and the installed power per footprint. unit surface may increase.
