Abstract: A water turbine is disclosed comprising a rotor mounted to be rotatable about an axis. The rotor comprises at least three blades for causing the rotor to rotate about the axis when the blades are located in flowing water. The rotor comprises a plurality of members in the form of a triangulated structure, and at least one of said members comprises one of said blades.

Abstract: Embodiments of the present invention provide a structure comprising: a flux guide comprising a plurality of resonant circuit elements (110, 120, 310F) each element comprising an electrically conductive loop portion (112, 122), opposed ends of the loop portion (112, 122) being coupled to one another through a capacitive element (114, 124), adjacent resonant elements of the flux guide (115, 315) being arranged to be magneto-inductively coupled to one another thereby to allow a magneto-inductive (MI) wave to be supported by the guide (115, 315), wherein at least one of the resonant elements (1205) is switchable between a first condition in which the element is arranged to support propagation of an MI wave along the waveguide and a second condition in which the element is arranged to prevent propagation of an MI wave along the waveguide.
