  • Patent number: 11101421
    Abstract: Embodiments relate to an apparatus for a nano-scale energy converter and an electric power generator. The apparatus includes two electrodes separated by a distance. The first electrode is manufactured to have a first work function value and the second electrode is manufactured to have a second work function value, with the first and second work function values being different. A cavity is formed by the distance between the first and second electrodes, and a nanofluid is disposed in the cavity. The nanofluid includes nanoparticles suspended in a dielectric medium. The nanoparticles have a third work function value that is greater than the first and second work function values. The relationship of the work function values of the nanoparticles to the work function values of the electrodes optimizes the transfer of electrons to the nanoparticles through Brownian motion and electron hopping.

  • Patent number: 9998036
    Abstract: A device for generating a movement is provided. The device has at least one magnet and a material that is arranged in the proximity of the magnet or in the magnet. The magnet exerts an attractive force on the material. The attractive force of the magnet is weakened by thermal action on at least one region of the material. The material is preferably not in superconductive state during the thermal action. Preferably, the material also has paramagnetic properties prior to the thermal action but diamagnetic properties after the thermal action. Also preferably, the device generates a circular movement.

  • Patent number: 9960715
    Abstract: Provided is a light activated piezoelectric converter comprising a cantilever vane coupled to a foundation. The vane comprises a first surface and a second surface. The first and second surfaces are generally co-planer and adjacent to a common boundary and have differing emissivities. A piezoelectric material is additionally coupled to the vane, arranged such that a deflection of the free end of the vane generates stress acting on the piezoelectric material. When the piezoelectric converter is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane and a thermal creep force across the planar surface generates a deflection of the vane, and a subsequent voltage induced by the stress on the piezoelectric material generates a voltage between a first electrode and second electrode in electrical contact with the piezoelectric material.

  • Patent number: 9923108
    Abstract: A solar power generation apparatus includes a stationary horizontal base. A stator is housed in the base, and a vertical column extends upward from the base. A conical-shaped rotor is rotatingly coupled at its apex to the column, while its base is near the stator. The rotor comprises an array of photovoltaic cells positioned on a surface of the rotor, wherein each cell converts light energy received from a light source to a direct current voltage, and an array of magnets positioned at a perimeter of the base of the rotor, wherein the magnets are electrically coupled to and receive direct current voltage from a respective cell. The rotating of the rotor past the stator converts the direct current voltage present at the array of magnets into an alternating current voltage.

  • Patent number: 9793829
    Abstract: Provided is a magneto-thermoelectric generator (MTG) device for energy harvesting and more particularly a device for converting waste thermal heat from a photovoltaic cell into mechanical energy and ultimately into electrical energy. Embodiments operate on the principle of thermally-induced switching between open and closed states of a ferromagnetic switch to generate mechanical oscillations that cause strain in a piezoelectric material, resulting in the generation of electrical energy. A structure capable of providing a non-linear restoring force provides mechanical energy to the device, which is a significant improvement over prior art MTG devices employing a linear spring restorative force. The device is also provided as a hybrid photovoltaic (PV)/MTG energy harvester for scavenging heat from photovoltaic cells. The hybrid PV/MTG device is particularly useful for harvesting waste heat to boost power generation, extend flight duration, and provide thermal management aboard HALE platforms.
