Abstract: A linear energy generator includes a field coil array that has one or more coils of wire, contained within a sealed generator housing and wrapped around a tube. A permanent magnet array is positioned within the tube and includes magnets that move relative to the field coil array to generate electricity. A magnetic lubricant is used between the tube and the permanent magnet array. The magnetic lubricant includes a solid phase component that includes ferromagnetic particles and a liquid phase component that coats the ferromagnetic particles to prevent corrosion and to improve lubricity of the solid phase component.

Abstract: Wave energy converter systems include a housing comprising a field coil array and a permanent magnet array within the housing configured to induce an electrical current in the field coil array. One or more peripheral magnet arrays are arranged around the housing and couple magnetically with the permanent magnet array. The peripheral magnet arrays cause the permanent magnet array to move within the housing in response to motion of the one or more peripheral magnet arrays and provide a magnetic shielding effect.

Abstract: An electrolysis cell includes an anode that has a low-density region formed from activated carbon and a high-density region formed from a plurality of graphite cylinders. There is a porous barrier that allows transport of water between the anode and a corrosion resistant cathode.

Abstract: A linear generator includes a permanent magnet array having at least two magnets arranged end-to-end. A set of conductive coils is arranged around the permanent magnet array. A four-phase full wave rectifier is configured to accept alternating current inputs from the set of conductive coils and to produce one or more direct current outputs. A summing circuit is configured to aggregate the one or more direct current outputs from the rectifier to produce a combined, rectified direct current output.

Abstract: A buoy includes a flotation device configured to float at surface of a body of water. A vibrational linear electric generator (VLEG) is configured to generate power from vibrational oscillations caused by waves using compressed repulsive magnetic fields focused by end magnetic field deflecting magnets. A power collection circuit, which includes a first battery, is configured to collect and store energy generated by the VLEG. One or more electronic components are powered by the vibrational linear electric generator.

Abstract: A spring suspension system includes a top spring assembly connected to a top end of a stator and a top end of a cable and a bottom spring assembly connected to a bottom end of the stator and a bottom end of the cable. The top spring assembly includes a central spring connected to the top end of the cable at a bottom end of the central spring and a set of symmetrically arranged springs, each connected to the top end of the stator and to a top end of the central spring, configured to accommodate torsional and rotational components of an input force.
