Google’s Patents on Wireless Energy Transfer
X Development LLC (formerly Google X) is an American semi-secret research and development facility and organization founded by Google in January 2010, which now operates as a subsidiary of Alphabet Inc. Over the last 4 years, X-Development has filed several patents with the USPTO regarding the wireless transmission of energy. The designs included in the patent filings credit Nikola Tesla’s first patents on the wireless transmission of energy. Every patent filed pertaining to a system capable of wireless energy transmission has received government approval. Together these patents shine a light on what the world’s third largest tech company has been building in the dark.
On January 9, 2018 X-Development was granted their first patent for “Wireless power delivery over medium range distances using magnetic, and common and differential mode-electric, near-field coupling.”
November 13, 2018 a second patent was granted for “Wireless Solar Power Delivery”. The patent summary states, “Example implementations may relate to systems for wirelessly transmitting power that is harnessed from solar energy. These systems may take the form of a solar panel system that includes solar cells that convert solar energy to electrical energy as well as various components that are configured to use this electrical energy to wirelessly provide electrical power. Alternatively, these systems may take the form of a wireless power transmission system that can connect to external solar panel systems and also includes components configured to receive electrical energy generated by these external solar panel systems and to then to use this electrical energy to wirelessly provide electrical power.”
In the midst of 2019, X-Development received three additional patents. These patents seemed to enhance the current system that had been built. The three patents granted include, “Wireless power delivery over medium range distances using magnetic, and common and differential mode-electric, near-field coupling”, “Modular mechanism enabled by mid-range wireless power”, and “Wireless power near-field repeater system that includes metamaterial arrays to suppress far-field radiation and power loss”. Heavy research was conducted on foreign terms used in the patent title due to my lack of technical knowledge on wireless energy transmission.
On December 12, 2020 science fiction truly becomes reality as X-Development received patent approval for a system capable of “Earth-Ionosphere Waveguide Power Transfer”. The abstract overview of the patent claims “a transmitter apparatus may be used transmit electrical power into the Earth-ionosphere waveguide in the form of an electromagnetic wave, which may, in turn, be detected by a receiver apparatus remote from the transmitter apparatus. A coupling strength between the transmitted electromagnetic wave and the one or more eigenmodes may be determined by measuring power received by the receiver apparatus in the detected electromagnetic wave. By iteratively adjusting parameters of the transmitter apparatus, determining the coupling strength, and refining a quantitative description of the eigenmodes, the eigenmodes may be harnessed for wireless power transmission throughout the Earth-ionosphere waveguide.”
Recently, on November 30, 2021 X-Development was granted a patent for “Using phased arrays of waveguide couplers in waveguide cavities to prevent illegitimate reception of power”. This is the last known patent filed and approved in relation to Google’s (X-Development) wireless power transfer system. It describes a security method to ensure unregistered/unsubscribed devices do not illegitimately receive power.
Through its subsidiary Development-X, Google has created and designed a system that can transfer energy wirelessly across great distances to power devices and other electronics. This method is made possible by sending electromagnetic waves to the ionosphere via waveguide couplers for quantum excitement of low-loss eigenmodes, thus harnessing the energy created and wirelessly transmitting it.
