A Patent for the Controversial & ‘Impossible’ Quantum Space Engine (EM Drive) Was Just Made Public

A Patent for the Controversial & ‘Impossible’ Quantum Space Engine (EM Drive) Was Just Made Public



Drive

 



A month ago, we published an article about the Cannae-Drive, which was invented by Guido Fetta, and tested by NASA over an eight day testing campaign that took place in August of 2013. It’s also known as the EM drive. It showed that a small amount of thrust was achieved inside a container without the use of any fuel. The results were then presented at the 50th Joint Propulsion Conference in Cleveland, Ohio.

You can access the paper (titled “Numerical and Experimental Results for a Novel Propulsion Technology Requiring no On-Board Propellant”) that was presented at the conference here, and inventor Guido Fetta’s paper here.

2016 has been a huge year for the EM drive, primarily because it was recently announced that it’s about to be tested in space, and NASA researchers reported a successful 10-week trial of their EM drive prototype, which led to the approval of Fetta being granted permission to test his own version in space.

Now, even more recently, the latest patent application for the new kind of rocket engine that generates thrust without any kind of exhaust or propellant was just released by the U.K. Intellectual Property office by investor Roger Shawyer (source).

“The patent process is a very significant process, it’s not like an academic peer review where everyone hides behind an anonymous review, it’s all out in the open,” Shawer told Marry-Ann Russon at the International Business Times.

He went on to say that “this is a proper, professional way of establishing prior ownership done by professionals in the patent office, and in order to publish my patent application, they had to first carry out a thorough examination of the physics in order to establish that the invention does not contravene the laws of physics.” 

Utilizing electromagnetic waves as fuel, the EM drive creates thrust by bouncing microwave photons back and forth in a cone-shaped metal cavity.

Now, Newton’s Third Law states that without exhaust you can’t produce thrust, or if something needs an “equal and opposite reaction,” something needs to be coming out of the back of the propulsion system to push it forward, and the EM drive doesn’t have that.

It’s called the law of conservation of momentum, but this invention taps into the ‘zero-point‘ field of energy/electromagnetic waves.

By the way, the laws of physics need to be changed to account for the fact that space is not empty.

Experiments from a number of researchers from around the world and NASA have shown that it can indeed produce thrust with enough power to propel a spacecraft.

This has huge implications. Think about it—propulsion systems that require no fuel.

Apparently, Shawyer is now working with a U.K. aerospace agency that will produce even more thrust, greater than what NASA and other researchers have already observed (source).

This is exciting because it basically proves that we have a limitless resource of energy to tap into and utilize for space travel  This is currently the biggest barrier for modern day space travel and exploration.

Science needs to be careful and stray far from getting caught up in the grip of scientific dogma. History has constantly shown us, especially within the realms of science, that what we accept as real always changes at another point in time. Our understanding and knowledge regarding the nature of our reality is constantly changing.

There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.” This statement (worldview statement) was made by Lord Kelvin in 1900, which was shattered five years later when Einstein published his paper on special relativity.

Today, engineers are inventing power generators that utilize these concepts, like Paramahamsa Tewari.

“These are not just fringe scientists with science fiction ideas. They are mainstream ideas being published in mainstream physics journals and being taken seriously by mainstream military and NASA type funders. I’ve been taken out on aircraft carriers by the Navy and shown what it is we have to replace if we have new energy sources to provide new fuel methods.” – Dr. Harold E. Puthoff, director of the Institute for Advanced Studies at Austin (source)

 

 

 

Invention Secrecy and the Problem With Patents

 

 

Did you know that invention secrecy is at an all time high? Did you know that the U.S. Government classifies over 500 million pages of documents each year? Justification for the mass classification of information is (apparently) done for the sake of “national security,” but as we know:

“The dangers of excessive and unwarranted concealment of pertinent facts far outweigh the dangers that are cited to justify them. There is a very grave danger that an announced need for an increased level of security will be seized upon by those anxious to expand its meaning to the very limits of censorship and concealment. That I do not tend to permit, so long as it’s in my control.” – JFK (source)

The U.S. Patent and Trademark Office is supposed to legally protect the inventions of entrepreneurs and companies, some of whom have developed groundbreaking technology. Unfortunately, it doesn’t work that way, as a number of documents obtained via the Freedom of Information Act (FOIA) reveal how the Patent Office has been using a secret system to withhold the approval of some applications.

A great example comes in the form of a 50-page document that was obtained by Kilpatrick Towsend & Stockton, LLP, who commonly represent major tech companies that include Apple, Google, and Twitter (to name a few). You can view that entire document HERE.

The program delaying patent applications is called the Sensitive Application Warning System (SWAS). Usually, when an application is submitted for a patent approval, it requires a couple of examiners who work with the Patent office to go through their process of approval. This process usually takes approximately 1 to 2 years, but  applications that are filed in SAWS must be approved by several people, and can be delayed for a number of years.

One great example (out of many) of delayed patent applications comes from Dr. Gerald F. Ross. He filed a patent application for a new invention he had devised to defeat the jamming of electromagnetic transmissions at specified frequencies. It was not until June 17, 2014 (almost 37 years later) that this patent was granted (source).

According to the Federation of American Scientists, a group of renowned scientists from various fields that was founded by many of the Manhattan Project scientists who wanted to prevent nuclear war, there were more than 5000 inventions that were under secrecy orders at the end of Fiscal Year 2014 (source).

This is all made possible by something called the “Invention Secrecy Act.” It was written up in 1951 and states that patent applications on new inventions can be subject to secrecy orders. These orders can restrict their publication if government agencies believe that their disclosure would be harmful to national security (source)(source).

As mentioned earlier, “national security” has become an excuse and justification for the classification of a large amount of information on a variety of topics that the public is deliberately kept in the dark about. Apparently, many of these projects and inventions go far above and beyond presidential knowledge.

“It is ironic that the U.S. should be fighting monstrously expensive wars allegedly to bring democracy to those countries, when it itself can no longer claim to be called a democracy when trillions, and I mean thousands of billions of dollars, have been spent on projects which both congress and the commander in chief know nothing about.”  – Paul Hellyer, Former Canadian Defence Minister  (source)

We don’t really know what other type of technologies are under restriction under the Invention Secrecy Act, but a previous list from 1971 was obtained by researcher Michael Ravnitzky. Most of the technology listed seems to be related to various military applications. You can view that list HERE (source).

As Steven Aftergood from the Federation of American Scientists reports:

“The 1971 list indicates that patents for solar photovoltaic generators were subject to review and possible restriction if the photovoltaics were more than 20% efficient. Energy conversion systems were likewise subject to review and possible restriction if they offered conversion efficiencies in excess of 70-80%” (source).






The Intellectual Property Office has published Shawyer's application featuring novel superconducting end plates.

EmDrive Exclusive: Roger Shawyer confirms MoD and DoD are interested in controversial space propulsion tech IBTimes UK





British EmDrive inventor Roger Shawyer has had his latest patent application for a next-generation superconducting thruster published by the UK Intellectual Property Office (IPO), showing that his development of the controversial space propulsion technology is going ahead.

The patent, available here, describes a thruster that features a single flat superconducting plate on one end, while the other end is a unique shaped plate that is non-superconducting.

In order to minimise the internal Doppler shift (the change in frequency or wavelength of a wave for an observer moving relative to its source), circular polarisation and a phase-locked loop control the microwave input to the thruster, which maximises thrust as it accelerates.

Shawyer told IBTimes UK that he submitted the patent for the next-generation microwave thrusters 18 months ago, and that the patent is significant as it is currently very difficult – not to mention expensive – to produce a shaped non-superconducting end plate, since it has to be mounted on a sapphire substrate.

"This is pretty significant because it enables you to easily manufacture these things, and we want to produce thousands of them," he said. "The patent makes the construction of a viable superconducting thruster easier, and it will produce a lot of thrust."

2016: A big year for EmDrive

How the EmDrive works

The EmDrive is the invention of British scientist Roger Shawyer, who proposed in 1999 that based on the theory of special relativity, electricity converted into microwaves and fired within a truncated cone-shaped closed metal cavity causes the microwave particles to exert more force on the flat surface at the large end of the cone (i.e. there is less combined particle momentum at the narrow end due to a reduction in group particle velocity), thereby generating thrust.

His critics say that according to the law of conservation of momentum, his theory cannot work as in order for a thruster to gain momentum in one direction, a propellant must be expelled in the opposite direction, and the EmDrive is a closed system.

However, Shawyer claims that following fundamental physics involving the theory of special relativity, the EmDrive does in fact preserve the law of conservation of momentum and energy.

Whether the technology actually works, there is no denying that 2016 has been a big year for the EmDrive. In mid-September, a respected space propulsion funding body in the US held a conference that included half a day dedicated to discussions about the EmDrive, led by a number of physicists, engineers and researchers.

Just before this, the American Institute of Aeronautics and Astronautics (AIAA) confirmed that it had peer-reviewed and accepted a paper on the EmDrive by Nasa Eagleworks researchers, which will be published in December 2016.

The researchers first posted on the Nasa Spaceflight forum in April 2015 and in November said they had succeeded in achieving thrust with the microwave thruster they built, although they didn't know how. In March, the researchers claimed that the paper was going through peer review, although they didn't know when it would be published.

There has been a great deal of debate over whether the EmDrive actually works. Many academics in the international space community continue to believe that it is complete nonsense, as the technology violates the law of conservation of momentum, and thus our understanding of physics.

In the meantime, Roger Shawyer, the British engineer/scientist who invented the EmDrive concept in 1999, is working with an unnamed UK aerospace company to develop the second generation of EmDrive, which will produce thrust many orders of magnitude greater than that observed by Eagleworks or any other laboratory.

 

Millions of pounds at stake on this patent

"The patent process is a very significant process, it's not like an academic peer review where everyone hides behind an anonymous review, it's all out in the open. This is a proper professional way of establishing prior ownership done by professionals in the patent office, and in order to publish my patent application, they had to first carry out a thorough examination of the physics in order to establish that the invention does not contravene the laws of physics," stressed Shawyer.

"There's millions of pounds at stake on this particular patent."

Shawyer has so far had four patents granted by the IPO – the first, GB2229865, was granted on 5 May 1993 and described the basic theory and construction of a cylindrical thruster with a shaped internal dielectric.

The second, GB2334761, granted on 21 March 2000, described the theory and construction of a tapered thruster with a cylindrical dielectric. This is essentially the same basic idea behind the NASA Eagleworks thruster that has been undergoing tests over the last two years.

The third patent, GB2399601, was granted on 13 March 2003, describing a second-generation EmDrive that uses no dielectric and employs superconducting technology to achieve high thrust.

Shawyer also has another patent still undergoing the patent review process – on 6 February 2013, the patent GB2493361 was published by the IPO, describing a thruster that uses shaped end plates and superconducting technology as a means of controlling the microwave input to maintain thrust under acceleration.

Alcubierre Warp Drive: Reaching the Nearest Star in Two Weeks


Alcubierre Warp Drive


Reaching the Nearest Star in Two Weeks


Alcubierre Warp Drive Time Control and Time Travel




An Overview and Comparison by Dr. David Lewis Anderson


An Alcubierre Warp Drive stretches spacetime in a wave causing the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship can ride the wave to accelerate to high speeds and time travel.

The Alcubierre drive, also known as the Alcubierre metric or Warp Drive, is a mathematical model of a spacetime exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "faster than light" (although not in a local sense - see below).

The key characteristics of the application of Alcubierre warp drives for time control and time travel are presented in the picture below. This is followed by more detail describing the effect below.


Alcubierre Warp Drive Time Control and Time Travel


Alcubierre Warp Drive Description

 

Alcubierre Warp Drive for Spacetime Travel
In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship would ride this wave inside a region known as a warp bubble of flat space.

Since the ship is not moving within this bubble, but carried along as the region itself moves, conventional relativistic effects such as time dilation do not apply in the way they would in the case of a ship moving at high velocity through flat spacetime. Also, this method of travel does not actually involve moving faster than light in a local sense, since a light beam within the bubble would still always move faster than the ship; it is only "faster than light" in the sense that, thanks to the contraction of the space in front of it, the ship could reach its destination faster than a light beam restricted to travelling outside the warp bubble. Thus, the Alcubierre drive does not contradict the conventional claim that relativity forbids a slower-than-light object to accelerate to faster-than-light speeds.
 

Alcubierre Metric

 

The Alcubierre Metric defines the so-called warp drive spacetime. This is a Lorentzian manifold which, if interpreted in the context of general relativity, exhibits features reminiscent of the warp drive from Star Trek: a warp bubble appears in previously flat spacetime and moves off at effectively superluminal speed. Inhabitants of the bubble feel no inertial effects. The object(s) within the bubble are not moving (locally) faster than light, instead, the space around them shifts so that the object(s) arrives at its destination faster than light would in normal space.

Alcubierre chose a specific form for the function f, but other choices give a simpler spacetime exhibiting the desired "warp drive" effects more clearly and simply.


Mathematics of the Alcubierre drive

 

Using the 3+1 formalism of general relativity, the spacetime is described by a foliation of space-like hypersurfaces of constant coordinate time t. The general form of the Alcubierre metric is:



where α is the lapse function that gives the interval of proper time between nearby hypersurfaces, βI is the shift vector that relates the spatial coordinate systems on different hypersurfaces and γij is a positive definite metric on each of the hypersurfaces. The particular form that Alcubierre studied is defined by:


where
and


with R > 0 and σ > 0 arbitrary parameters. Alcubierre's specific form of the metric can thus be written;


With this particular form of the metric, it can be shown that the energy density measured by observers whose 4-velocity is normal to the hypersurfaces is given by

 

Alcubierre Warp Drive for Time Travel
where g is the determinant of the metric tensor. Thus, as the energy density is negative, one needs exotic matter to travel faster than the speed of light. The existence of exotic matter is not theoretically ruled out, the Casimir effect and the accelerating universe both lending support to the proposed existence of such matter. However, generating enough exotic matter and sustaining it to perform feats such as faster-than-light travel (and also to keep open the 'throat' of a wormhole) is thought to be impractical. Low has argued that within the context of general relativity, it is impossible to construct a warp drive in the absence of exotic matter. It is generally believed that a consistent theory of quantum gravity will resolve such issues once and for all.

 

Physics of the Alcubierre drive

 

Alcubierre Warp Drive Manifold
For those familiar with the effects of special relativity, such as Lorentz contraction and time dilation, the Alcubierre metric has some apparently peculiar aspects. In particular, Alcubierre has shown that even when the ship is accelerating, it travels on a free-fall geodesic. In other words, a ship using the warp to accelerate and decelerate is always in free fall, and the crew would experience no accelerational g-forces. Enormous tidal forces would be present near the edges of the flat-space volume because of the large space curvature there, but by suitable specification of the metric, these would be made very small within the volume occupied by the ship.

The original warp drive metric, and simple variants of it, happen to have the ADM form which is often used in discussing the initial value formulation of general relativity. This may explain the widespread misconception that this spacetime is a solution of the field equation of general relativity. Metrics in ADM form are adapted to a certain family of inertial observers, but these observers are not really physically distinguished from other such families. Alcubierre interpreted his "warp bubble" in terms of a contraction of "space" ahead of the bubble and an expansion behind. But this interpretation might be misleading, since the contraction and expansion actually refers to the relative motion of nearby members of the family of ADM observers.

In general relativity, one often first specifies a plausible distribution of matter and energy, and then finds the geometry of the spacetime associated with it; but it is also possible to run the Einstein field equations in the other direction, first specifying a metric and then finding the energy-momentum tensor associated with it, and this is what Alcubierre did in building his metric. This practice means that the solution can violate various energy conditions and require exotic matter.

The need for exotic matter leads to questions about whether it is actually possible to find a way to distribute the matter in an initial spacetime which lacks a "warp bubble" in such a way that the bubble will be created at a later time. Yet another problem is that, according to Serguei Krasnikov, it would be impossible to generate the bubble without being able to force the exotic matter to move at locally FTL speeds, which would require the existence of tachyons. Some methods have been suggested which would avoid the problem of tachyonic motion, but would probably generate a naked singularity at the front of the bubble.

 

Difficulties

 

Alcubierre Warp Drive for Spacetime Travel
Significant problems with the metric of this form stem from the fact that all known warp drive spacetimes violate various energy conditions. It is true that certain experimentally verified quantum phenomena, such as the Casimir effect, when described in the context of the quantum field theories, lead to stress-energy tensors which also violate the energy conditions and so one might hope that Alcubierre type warp drives could perhaps be physically realized by clever engineering taking advantage of such quantum effects.

However, if certain quantum inequalities conjectured by Ford and Roman hold, then the energy requirements for some warp drives may be absurdly gigantic, e.g. the energy -1067gram equivalent might be required to transport a small spaceship across the Milky Way galaxy. This is orders of magnitude greater than the mass of the universe. Counterarguments to these apparent problems have been offered, but not everyone is convinced they can be overcome.

alcubierre warp drive
Chris Van Den Broeck, in 1999, has tried to address the potential issues. By contracting the 3+1 dimensional surface area of the 'bubble' being transported by the drive, while at the same time expanding the 3 dimensional volume contained inside, Van Den Broeck was able to reduce the total energy needed to transport small atoms to less than 3 solar masses. Later, by slightly modifying the Van Den Broeck metric, Krasnikov reduced the necessary total amount of negative energy to a few milligrams.

Krasnikov proposed that, if tachyonic matter could not be found or used, then a solution might be to arrange for masses along the path of the vessel to be set in motion in such a way that the required field was produced. But in this case the Alcubierre Drive vessel is not able to go dashing around the galaxy at will. It is only able to travel routes which, like a railroad, have first been equipped with the necessary infrastructure.


The pilot inside the bubble is causally disconnected with its walls and cannot carry out any action outside the bubble. However, it is necessary to place devices along the route in advance, and since the pilot cannot do this while "in transit", the bubble cannot be used for the first trip to a distant star. In other words, to travel to Vega (which is 26 light-years from the Earth) one first has to arrange everything so that the bubble moving toward Vega with a superluminal velocity would appear and these arrangements will always take more than 26 years.
 
Coule has argued that schemes such as the one proposed by Alcubierre are not feasible because the matter to be placed on the road beforehand has to be placed at superluminal speed. Thus, according to Coule, an Alcubierre Drive is required in order to build an Alcubierre Drive. Since none have been proven to exist already then the drive is impossible to construct, even if the metric is physically meaningful. Coule argues that an analogous objection will apply to any proposed method of constructing an Alcubierre Drive.
