I’m kind of shocked that I haven’t done an anti-gravity patent yet! Allow me to present the advanced technology propulsion study in penance. The application was filed internationally in 1997, including applications in Australia, Germany, Israel, Japan, and Canada. It was granted in at least Australia, Canada, and Germany, which… Yeah. A lot of pleasant nonsense follows.
The application was filed in that awkward time period where applications were being published, but their file histories weren’t, so I can’t say exactly why the U.S. Examiner decided not to allow the case, while other countries were more permissive. However, I hope it had to do with passages such as this:
Inertial levitation technology, i. e. thrust levitation, is the technology used by a vehicle with a propulsion system that can convert vehicle onboard power into linear inertia, without using the expulsion of mass, as is done by a rocket, or the movement of air or water as is done by aircraft propellers and the screws of marine boats and ships.USPP 2001/0004098, ¶2
It’s nice when they tell you directly that they don’t follow the laws of physics. The specification is kind enough to provide a design for The Enterprise Clipper, which is a “suggested Plan Form Configuration for an intergalactic or at least interstellar vehicle”:
We also dip into the topic of warp speed:
A small propulsion system that is capable of 10 million shp output is likely to be the first practical warp drive.USPP 2001/0004098, ¶105
To be fair to them, they have defined “Warp 1” to be an acceleration of twenty-two times the force of gravity at the Earth’s surface, which is not all that fast. Star Trek’s warp drives put Warp 1 at the speed of light. Of course, it wouldn’t be fair to insist that a real-world invention keeps to the standards set by science fiction…
At least, it wouldn’t if the specification didn’t include a synopsis of the Star Trek: Voyager episode Threshold, where Tom Paris goes at Warp 10 and hyper-evolves into some kind of amphibian. See ¶¶143-144.
True to form, the nonsense goes on for page after page, and I do not have the energy to sift through it all. As best as I can figure it out, the device is supposed to use multiple spinning discs to with the angular momentums of the discs adding together in some way to create a directional thrust. As a general matter though, if you have to introduce a whole new “Correlation Theory of Relativity” (¶¶112-117, 249-291) to explain your invention, you might be barking up the wrong tree.
