Patent number: 11608197Abstract: The present invention describes methods, systems, and devices for utilizing high-intensity regions within atmospheres of planetary bodies to receive and harvest electricity. Such high-intensity regions are formed as a result of the combined gravitational forces affecting a given planetary body and particularly the particles within the atmosphere of that planetary body. The combined gravitational forces result in a gravitational resonant frequency which affects the atmosphere most intensely within said high-intensity regions. By determining moments of gravitational resonant frequencies based on a given location, the methods, systems, and devices described herein utilize the energy provided within the high-intensity regions during the determined moments. Harvesting and further transmitting the collected energy is also disclosed.Type: GrantFiled: August 12, 2020Date of Patent: March 21, 2023Inventor: Vadim Kukharev
