Directional Reactive Power Ground Plane Transmission

Oak Ridge National Laboratory

Contact ORNL About This Technology

Technology Marketing SummaryORNL researchers have developed a pioneering power alternative to batteries using directional reactive power. Batteries are currently the primary option for powering mobile electronic equipment; however, batteries are heavy and battery life is limited. Reactive power is the phenomenon that occurs when alternating voltage and current are 90 degrees out-of-phase with respect to time. This phenomenon allows electrical transmission on a single wire without a return path. DescriptionThe invention can transmit electrical power through the surface of the earth via electromagnetic ground waves. By using the Earth as a ground plane, the invention avoids any need for transmission wires. Any kind of electric device can be served by this method, including stationary or moving electric vehicles and electronic devices. Benefits
  • On demand electrical energy for mobile or fixed electronic devices
  • Eliminates or reduces the need for batteries
  • Eliminates wires, plugs, and all the apparatus for traditional electrical transmission
  • Allows electrical energy to be focused to specific points
  • Provides greater mobility by eliminating battery weight
Applications and Industries
  • Wireless electrical energy transfer systems
  • Recharging electric vehicles and electronic devices
  • Recharging or powering existing equipment from a power source located miles away
