Publication number: 20170263337Abstract: Nuclear fusion processes with enhanced rates may be realized by providing energetic electrons in an environment containing a suitable fuel gas, a liquid fuel source, a solid fuel source, a plasma fuel source, or any combination thereof. The fuel source may be deuterium, tritium, a combination thereof, or any fuel source capable of creating deeply screened and/or neutral nuclei when exposed to energetic electrons. Under proper conditions, at least some of the deeply screened and/or neutral nuclei fuse with other nuclei. Neutral versions of deuteron and/or triton nuclei may be created by bringing neutrons with certain energy levels (e.g., around 3 MeV, but optionally less or much less than 3 MeV) into interaction with other neutrons, forming neutral versions of deuterons and/or tritons. Such processes may be used for power generation, heat production, nuclear waste remediation, material creation, and/or medical isotope production, for example.Type: ApplicationFiled: March 9, 2016Publication date: September 14, 2017Applicants: PineSci Consulting, NASA Glenn Research CenterInventors: Vladimir Pines, Marianna Pines, Bruce Steinetz, Arnon Chait, Gustave Fralick, Robert Hendricks, Paul Westmeyer

Patent number: 6967462Abstract: A system for providing wireless, charging power and/or primary power to electronic/electrical devices is described whereby microwave energy is employed. Microwave energy is focused by a power transmitter comprising one or more adaptively-phased microwave array emitters onto a device to be charged. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and/or for primary power. A locator signal generated by the device to be charged is analyzed by the system to determine the location of the device to be charged relative to the microwave array emitters, permitting the microwave energy to be directly specifically towards the device to be charged. Backscatter detectors respond to backscatter energy reflected off of any obstacle between the device to be charged and the microwave array emitters. Power to any obstructed microwave array emitter is reduced until the obstruction is removed.Type: GrantFiled: June 5, 2003Date of Patent: November 22, 2005Assignee: NASA Glenn Research CenterInventor: Geoffrey A. Landis
