Abstract

Apparatuses and associated methods for converting wave energy into electrical energy are disclosed herein. In some embodiments, a surface-based buoy can be connected to a magnetostrictive element that changes its output voltage when subjected to the in tension. To keep the heave plate under tension, a tether with a heave plate can be attached to the magnetostrictive element. Since the magnetostrictive element can be sensitive to zero tension (e.g., a slack in the tether) followed by a sudden increase in the tension, in at least some embodiments it is preferred to keep the magnetostrictive element tensioned at all times. In some embodiments of the present technology, an inertia-dominated heave plate may be designed to sink faster than the buoy falls in the trough of the wave, therefore keeping the tether tensioned at all times. For example, the design (e.g., mass, diameter, height) of the heave plate can be such that the static force of gravity S exceeds a sum of the drag D and inertia / under expected wave conditions.

Abstract

Embodiments described herein relate to a method and device for harvesting energy from a fluid flow by converting the kinetic energy of the flow into vibrational energy, which then may be converted to electrical energy by a magnetostrictive-based vibrational energy harvester. Some embodiments of this device rely on the principle of vortex-induced vibrations, where the frequency of the induced vibration is of the same order as the frequency of vortex shedding. Some embodiments of this device rely on the principle of turbulence- induced vibration, where the frequency of vibration can be significantly higher than the vortex shedding frequency, and is related to the turbulence frequency of the flow. Some embodiments also relate to converting energy from pressure pulses or differentials in the fluid. These embodiments in no way limit the vibration induction mechanism, and other principles of flow-induced vibration may be used in conjunction with the magnetostrictive-based vibrational energy harvester.

Abstract

An apparatus for harvesting electrical power from hydrodynamic energy, the apparatus including a buoy or other water flotation device connected to an anchor by a tether and a magnetostrictive component having an internal pre-stressed magnetostrictive core that experiences at least a part of load changes experienced by the tether. The magnetic property of the magnetostrictive core is configured to change with changes in stress within the magnetostrictive core along at least one direction within the magnetostrictive component. The hydrodynamic energy acting on the buoy or other water flotation device results in changes in force within the tether, which in turn changes the stress within the magnetostrictive core and consequently changes a magnetic property. The magnetostrictive component is also configured such that the change in the magnetic property will result in a change in magnetic flux, which change can be used to generate electrical power.

A method and device (100) for generating electricity from ocean waves. The device (100) includes at least one magnetostrictive element (106) and one or more electrically conductive coils or circuits (112). When the magnetostrictive element (106) is deployed in a body of water (102), the motion of the body of water (102), including wave motion, causes changes in the strain of the magnetostrictive element (106). The electrically conductive coil or circuit (112) is within the vicinity of the magnetostrictive element (106). A corresponding change in magnetic field around the magnetostrictive element (106) generates an electric voltage and/or electric current in the electrically conductive coil or circuit (112).
