  • Submersible power plant for producing electrical power
    Patent number: 11542908
    Abstract: A submersible power plant and a method for providing a submersible power plant. The submersible power plant includes an anchoring provided at a minimum depth and a vehicle including at least one wing. The vehicle is arranged to be secured to the anchoring by at least one tether rotatably attached to the anchoring by an anchoring coupling and attached to the vehicle by at least one vehicle coupling. The submersible power plant is completely submerged in a body of fluid both during operation and non-operation of the submersible power plant and the tether has an unextended tether length between 2-20 times a wingspan of the wing, specifically between 3-12 times the wingspan of the wing, more specifically between 5-10 times the wingspan of the wing.
