  • Publication number: 20230361696
    Abstract: Disclosed is a kinetic energy harvest and electrical energy storage feedback cell that combines the 2-dimensional superconductor behaviour induced by a ferroelectric-metal with a quantum. Hall Effect placed within two conductor/semiconductor materials with different chemical potentials. The feedback corresponding to external and internal conduction and tunnelling of the electrons in the cell allows the electrical potential difference to increase during discharge of the cell with a load. The feedback cell harvests kinetic energy, heat and store electrostatic and electrochemical energy that at room temperature the supercurrent can be induced during several years in feedback and can be used as part of a transistor, a computer, a photovoltaic cell or panel, a wind turbine, a vehicle, a ship, a satellite, an airplane, a remote access circuit, a building, smart grid, electric power transmission, transformers, power storage devices, electric motors and as a part of other several components or products.

  • Publication number: 20220223742
    Abstract: The present invention relates to a one-electrode cell and series of two or more cells as a device at temperatures from below to above room temperature comprising a very high permittivity ferroelectric. In a device constituted by one or more ferroelectricity-induced superconductor cells, the cells do not have to be in physical contact with one another; one terminal can be connected to a first cell and the other connected to a third cell without physical contact between any of the three cells. With the spontaneous and dynamic alignment of the dipoles of the ferroelectric, a potential difference is induced in different points of the surface of the cell, cells or device and a current can be harvested by conductor-terminals. The present invention can be used for contactless charging of energy storage devices and as a part of several components or products.
