There's another patent held by Salvatore Pais as well, "High frequency gravitational wave generator": https://patents.google.com/patent/US10322827B2/en https://patents.google.com/patent/US10322827B2/en Both patents have very interesting descriptions, which are good fun reads if nothing else - there are a couple extraordinary claims. Pais actually discusses the patents & the approval/appeal process, among other things, in this interview with podcaster Kurt Jaimungal (patent discussion is ~15 minutes in): https://www.youtube.com/watch?v=5E6QyAhTB3o https://www.youtube.com/watch?v=5E6QyAhTB3o --- Here's a couple other fun patents in this area: Triangular spacecraft - https://patents.google.com/patent/US20060145019A1 https://patents.google.com/patent/US20060145019A1 Photon spacecraft - https://patents.google.com/patent/US20060144035A1/ https://patents.google.com/patent/US20060144035A1/ One more interesting individual whose work you could look into, if this stuff intrigues you, is Dr. Eric Davis - he wrote/contributed to a number of papers that came out of AATIP (DoD UFO program run from 2007-2012). List of papers is here, many can be found through online research: https://irp.fas.org/dia/aatip-list.pdf https://irp.fas.org/dia/aatip-list.pdf
