I just noticed this thread today and took a look at the site and pdf's. On this one, even I'm skeptical. They claim 4N thrust! That would be fantastic. But alas, not likely. They assume some kind of mass density of the 'vacuum ' ~10^-21 kg/m^3 which there is no evidence for that I've ever seen.
If the vacuum has a mass, even if it is small, then ... that will be another story.

Natural permittivity and permeability of empty space are both a small but non-zero value.But if the vacuum did have mass, I wonder how would we measure it?
The results of experimental studies of non-electromagnetic interaction in vacuum of closely spaced, mechanically unconnected, rotating disks are presented. It is established that at high angular velocities forces of interaction between the disks arise, causing precession and elastic deformation (screw twisting) of the surfaces of the disks during their joint rotation. In this case, energy is transferred from the rotating disk to the initially stationary disk, leading to its rotation, as well as mutual braking and heating of the disks during their simultaneous rotation.
Significant dynamic imbalance of the discs contributed to their intense vibration and the above-described effect of the interaction of the discs: vibrationand then the appearance of a bending wave was observed with gaps between the disks up to 3 mm.In the experiments under the same conditions, but in the absence of vacuum (normal atmospheric pressure in the chamber), the above effects were not manifested.Strong vibration of the discs was not excited, and a bending wave was not observed even when the initial clearance between the discs was less than 1 mm.At the same time, when one of the electric motors was turned off (rotation in a vacuum), and its disk stopped, the second electric motor untwisted to maximumrevolutions of the order of 180 - 200 1 / s. When you turn on the first electric motor, the speed of the second motor again decreased significantly. Rotation frequencyboth disks again amounted to about 90 - 100 1 / s. Thus, with repeated repetition of experiments, it was experimentally established that in the process of jointcounter rotation in a vacuum, a sufficiently strong contactless mutual braking of the disks was observed.
Vladimir Samokhvalov (Samara) presented in a double report the results of studies on the mutual influence of rotating masses (thin disks in vacuum). The report, accompanied by a video demonstration of the experiments, immediately aroused genuine interest and was repeatedly interrupted by questions. The obvious effect of the transfer of significant energy between divided rotating disks in a vacuum gave rise to spontaneous brain storming of listeners to explain the nature of the effect and the development of experiments. In the second report, Vladimir Nikolaevich talked about other experiments that testify to the mass-dynamic effects.
Studies of direct relationships between changes in the energy fluxes of solar radiation (with changing solar activity in cycles No. 21, 22 and 23) with temporary variations in optical and synoptic weather were performed at the Cheget (3.1 km) and Solnechnaya mountain stations (2 , 1km) in the North Caucasus. The subsequent comprehension of the entire volume of the results obtained and the studies involved in areas related to atmospheric physics: meteorology, solar-terrestrial physics and astrophysics made it possible to detect the presence of spiral-vortex radiation (SVI) with background energy level in solar fluxes approximately 104 erg / s · cm2, reaching values of ~ 105 - 106 in case of high solar activity
About spiral vortex field Solar spiral-vortex radiation (field) is one of the forms of matter, and, at the same time, a new physical object. It transfers the interaction, possessing energy, momentum, angular and orbital moments. A spiral-vortex field (SVP), like an electromagnetic field, can exist by itself, but unlike an ELMI, it should already be initially perceived as a spectrummulti-scale solitons, easily penetrating into other bodies and effectively interacting with their structural elements

What is needed is an engine, a device that creates fluctuations in energy-mass (in the local zone). A simple test body (for example, a flat steel disk or a sphere that is at rest) cannot "study the momentum" by itself, and perhaps such a body cannot be used as a detector in principle.I repeat - a simple test body cannot be used as a detector.

They go on to claim that the vacuum used to be called ether which is even more wrong, and puts everything else to bed, because the ether has already been proven to not exist, so their claims are worthless.

Much of the search for dark matter—the invisible substance comprising 80 percent of all the mass in the cosmos—has focused on one type: weakly interacting massive particles (WIMPs). However, there's another strong contender: the axion, a very low-mass particle that could be numerous enough to play the part of dark matter. Axions were predicted in the 1970s because they provide a fix for a problem in particle physics, but they have yet to be seen experimentally.Or so we've thought. Maybe they have been found, and we just didn't know what we were looking at. That's the premise of a provocative paper by Christian Beck. A certain anomaly that's been detected in superconducting experiments could be the result of axions passing through the apparatus. If this thesis is correct, then researchers have already detected axions with a tiny mass of about 0.11 thousandths of an electron volt (meV), or about 2×10-10 times the mass of an electron.
at 0:13 Artem Madatov..there are electronic keys, everything is complicated here.And this oscillatory system comes into action with the help of an external source of energyIt deforms the vacuum and starts to speed it up and it means, as they say, it is drawn into one hole, flies in - and from another hole (here a solid channel) - flies out. Thus, a reactive jet is formed, and the device acquires acceleration in the other direction.at 0:55 Volodymyr AstapenkoThe next step that will show you how it works is the spacewalk.Yes, this is still the closest space, it is within the orbit of the Earth, where the vacuum is already a natural vacuum, not the one that we create in laboratory conditions on Earth.1:26 Max TkachenkoThis is a very non-standard project, initially we did not want to consider it at all, and somehow work with it, but after a while, realizing its value, we formed a fairly professional team and began to develop it.
Just a question - it is believed that dark matter is in the vicinity of galaxies, then it should be in the vicinity of the solar system and in the vicinity of the planet Earth. Dark matter can have magnetic properties and it can be in the magnetic fields of the planet Earth, possibly in some equilibrium with the pressure of the solar wind. If reserves of dark matter can be found on the surface of the planet, then it can be sucked, pushed with the help of a system of magnets. If it's that simple - why haven't we found it yet? I read an article "Could dark matter be hiding in plain sight in existing experiments?"https://arstechnica.com/science/2013/12/could-dark-matter-be-hiding-in-plain-sight-in-existing-experiments/
It is not excluded that Dark matter also interacts via the weak nuclear interaction. Most dark matter searches use that property. If dark matter interacts only via gravitation, then that's going to be real difficult to detect in the lab. Electromagnetic interaction is excluded experimentally.
Dark matter by definition only interacts via gravity.

What I’ve found, however, is that the superconductors are needed only to create a certain density of electrons, so in the experiments you seen in this video we’re working with very thin gold layers which generate the same effect at room temperature.My latest research shows that working with composite materials that do not include superconductors at all, we’re able to create gravity fields, in vacuum, in the air, and so far in every object placed within the vicinity of this experimental gravity generator. It’s a much more efficient method.
For the time being, we have come back to rotating disks, but we’re using a composite structure now, and under certain conditions we’re creating this gravitational modification. I also plan to begin working with rotating magnet fields, which are practically the same thing as a rotating body. But so, but in a, in a bit different way. So the mechanism is a bit different
Hi guys,I want to share with you my idea about gravity.The space vacuum (between planets, stars, between atoms maybe) seems to be not fully empty (at least we know that the energy of vacuum is not zero).... [snip long post]...I think that we can move things in space, just causing vibration in them.We are changing the momentum of all particles there.I think that it is possible using some kind of very low infrasound.And we are reaching this effect using rockets, causing some kind of eartquakes because of burning fuel, so it is like creating bombs, but maybe there is some kind of easier way to create just a vibration of all things in the direction we need to move.And I don't think that it breaks the law of conservation of momentum (because vacuum is not empty).We just need to create vibration like it was done using burning of fuel.And if it accelerates the objects using just a ship's electricity energy, we can achieve the thrust to reach planets and stars in short terms with 1G on board.Sorry for not native English language.
