Problems solved by technology

[0009] b) Known systems are inefficient due to large losses during conversion and transfer of the converted energy
Since the converted energy is consumed at remote locations most of the time, losses during energy transfer can have a significant impact on system performance
[0010] c) Components used in known systems are subject to a great deal of tear and wear, and / or the system is designed such that inspection and maintenance are complex and expensive

Embodiment Construction

[0058] In the following description, Z defines the horizontal fluid flow direction, X defines the horizontal direction perpendicular to the fluid flow direction, and Y defines the vertical direction perpendicular to the fluid flow direction.

[0059] figure 1 There is shown a system indicated with reference numeral 1 for converting energy from a fluid flow 50 into transmittable energy. System 1 includes fluid drive device 200 connected to tether 300 , wherein tether 300 is coupled with base station 400 . The base station 400 is attached or attachable to a mooring arrangement 480 located at the bottom 40 of an ocean, river, lake or the like.

[0060]Preferably, the base station 400 is provided with a conversion device 410 comprising at least one hydraulic cylinder. In this regard, the tether 300 is preferably connected to a piston 412 movable in a hydraulic cylinder such that movement of the piston 412 causes hydraulic fluid to be displaced in the hydraulic system of which th...

Abstract

System for power generation from a flow of fluid, comprising a fluid driven device connected to a tether wherein the tether is coupled with a base station to convert energy from the flow of fluid intotransportable energy, wherein the fluid driven device comprises a frame provided with adjustable vanes, and wherein the vanes are adjustable for setting into a predefine position relative to the flowof fluid. The fluid driven device comprises a working mode and a retraction mode, wherein in the working mode the vanes are set in a first predetermined position to generate a lift force from the flow of fluid, and wherein in the retraction mode the vanes are set in a second predetermined position to provide a low drag level to the flow of fluid, and wherein the work performed during working modeis larger than the work supplied during retraction mode.

Description

technical field [0001] The present invention relates to a system for converting from fluid flow to transferable energy comprising a fluid drive connected to a tether, wherein the tether is coupled to a base station. Background technique [0002] Energy demand for human consumption has grown significantly over the past few decades and is projected to increase further due to the growing world population. According to physicists' definition, energy can neither be created nor consumed or destroyed. However, energy can be converted or transferred into different forms. These forms can be, for example, mechanical or electrical energy. Currently, a significant portion of the mechanical and electrical energy provided is based on energy conversion from the combustion of fossil fuels. These fossil fuels have been developed over billions of years, and it is predicted that humans will use them for hundreds of years. In addition to the question that fossil fuels will run out at some p...
