These Engineers Built The Bladeless Ion-Propelled Plane! | Antigravity Devices Community
This Silent Aircraft Flies Using Ion Thrusters; No Fuel Or Moving Parts Involved!
Since 1921, scientists have been trying to develop an aircraft that flies using ion thrusters – albeit at first, it was mistaken for anti-gravity technology. The concept hasn’t been successful until now because our technology wasn’t advanced enough.
Recent key advances have made it possible for a team of scientists, led by Steven Barrett from MIT (the Massachusetts Institute of Technology), to create an electroaerodynamic-powered plane – an aircraft that uses solid-state propulsion. The plane doesn’t use propellers or jet engines with expendable fuel. Instead, it’s powered by an ion drive.
Barrett says in the video:
The future of flight shouldn’t be things with propellers and turbines. [It] should be more like what you see in Star Trek, with a kind of blue glow and something that silently glides through the air.
Flight Testing And Plane Design
Their prototype aircraft has a 16 feet (5 meters) wingspan and weighs 5.4 pounds (2.45 kilograms).
Several thin electrodes are running across the wings, which also have thin wires at the front and an aerofoil (a curved surface to produce the lift) at the back.
The thin wires are charged to positive 20,000 volts, and the aerofoil is charged to negative 20,000 volts. This creates a strong electric field.
The electric field strips nitrogen molecules in the air of electrons, producing ions in the front. As the ions accelerate to the back, they generate an ionic wind, giving the plane thrust.
The plane doesn’t require a propellant. It only relies on those thin wires and an off-the-shelf lithium-polymer battery.
Barrett told IFLScience:
The basic idea is that if you ionize the air, which means removing an electron from it, you can accelerate the air with an electric field. Like the force you get if you rub a balloon on your head.
The plane flew around 200 feet (60 meters) in approximately 12 seconds over the course of ten test flights in a gym. It had a thrust efficiency of about 2.6%, but that figure increases as the system’s efficiency increases. So, a 670 miles (1,080 kilometers) per hour plane would theoretically be 50% efficient.
Barrett said:
It was exhilarating. Then it crashed into the wall, which wasn’t ideal.
[Nevertheless], it is possible to fly planes that are solid-state, and we demonstrated that for the first time.
I don’t yet know whether you’ll see large aircraft carrying people any time soon, but obviously, I’d be very excited if that was the case.
The technology is still minimal, and the plane very much a prototype, but the future potential is inspiring.
For now, the team continue to test the plane in the hopes that people could use its thrust system to power small delivery and inspection drones in the near-term. They would be near-silent and propeller-less, making them safer.
Barrett said:
Imagine 10 or 20 years from now—we could have drones everywhere. If those are all noisy, they’ll degrade our quality of life. But this is silent.
So far, the team has gotten the plane to turn in the air (with remote control) instead of simply flying in a straight line – so advances are being made! In the long-term, such an airplane could help the aviation industry become carbon neutral.
Was "Nikolas Tesla" Suffering From a Serious Disorder? | Antigravity Devices Community
Was "Nikolas Tesla" Suffering From a Serious Disorder?
Nikola Tesla (1856–1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
Born in 1856 and raised in Smiljan, then part of the Austrian Empire, but today part of modern-day Croatia, Tesla received an advanced education in engineering and Physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry.
He emigrated to the United States in 1884, where he would become a naturalised citizen. He went on to become an inventor, electrical engineer and mechanical engineer. In fact, he was dubbed by many as “the man who invented the 20th Century”. Tesla was a brilliant scientist and engineer who earned more than 700 patents with inventions, he is perhaps most famous for developing the alternating current, but his work also led to advances in wireless communications, lasers, x-rays, radar, lighting, robotics, and much more. In fact when he died in 1943, much of his work remained classified by the US government.
It’s reported that Tesla started showing symptoms of OCD around 1917 when he became obsessed with the number three. When taking his daily swim at the public pool, he always swam 33 laps, but if he lost count he said he couldn’t leave, and instead had to start over from zero. He often had an urge to circle a city block three times before entering a building. When leaving a building he had to turn right only, and walk around the entire block before becoming “free” and being able to leave.
Tesla worked every day from 9:00 a.m. until 6:00 p.m. or later, with dinner at a very specific 8:10 p.m. Tesla would then resume his work, often until 3:00 a.m. For exercise, Tesla walked between 8 and 10 miles (13 and 16 km) per day. He curled his toes one hundred times for each foot every night, saying that it stimulated his brain cells.

He also became obsessed with germs, he polished every dining implement he used to perfection, demanded three folded cloth napkins beside his plate at every meal using 18 napkins. He also stayed in a hotel room with a number divisible by three (he lived the last ten years of his life in suite 3327 on the 33rd floor of the New Yorker Hotel). He considered jewellery revolting and especially hated pearl earrings.
It’s also reported that he would count his jaw movements when chewing food and habitually surprised dinner guests by estimating the weight of his meal before taking the first bite because when eating, he found he couldn’t enjoy food unless he first mentally calculated the volume, which of course are almost certainly OCD symptoms. Tesla’s fear of germs became so great when meeting people he would decline to shake hands and he had great distaste for touching hair.
His lifelong celibacy and tendency to seclude himself could have been OCD related too, although Tesla himself is claimed to have said this enhanced concentration on his various experiments.
Huge, Hovering and Silent: The Mystery of 'Black Triangle' UFOs | Antigravity Devices Community
Huge, Hovering and Silent: The Mystery of 'Black Triangle' UFOs
Some speculate they are super-secret US spy craft. Others question whether they might be from elsewhere, conducting some kind of surveillance.
Within the larger mystery of the UFO phenomenon is another, still-unsolved puzzle: Why do so many reports involve strange, triangular-shaped craft—often described as dark in color, virtually noiseless and the size of a football field or larger? What, exactly, are they? And why are so many witnessed hovering or moving slowly and methodically, with no visible contrails?
In the years after the U.S. Air Force coined the term “unidentified flying object” in 1952, reports often referred to UFOs generically as flying saucers. But witnesses then, and since, have described a wide array of shapes: saucers (or two saucers put together), eggs, hats, cigars, boomerangs, lightbulbs—even Tic Tac candies.
Among the most commonly reported shapes were V-shaped, arrowhead-like or triangular. David Marler, UFO researcher and author of Triangular UFOs: An Estimate of the Situation, says he has reviewed more than 17,000 case files involving unidentified triangular craft, sometimes called “black triangles.” Whether the sightings represent advanced U.S. spy craft—as some speculate—or something of unknown origin, their purpose remains mysterious. Given their consistent hovering behavior, Marler says, they might be engaged in “surveillance of some nature—or scanning. Or analyzing the topography.”
“There have been many instances in which these vehicles have been observed over bases operated by the Strategic Air Command,” says Chris Mellon, former deputy assistant secretary of defense for intelligence during the Clinton and George W. Bush administrations, whose career has focused on unconventional threats to American security. Mellon is now an integral part of the investigative team featured on HISTORY's “Unidentified: Inside America’s UFO Investigation.”
An International Phenomenon
In the 1950s, ‘60s and ‘70s, triangular UFO reports hailed from across the U.S. and beyond. During the 1960s, at the height of Cold War UFO fever, mysterious flying triangles were reported over Connecticut, Georgia, Pennsylvania and Texas—as well as London, Madrid and Czechoslovakia. In 1969, two National Guard pilots tailed a “triangular shaped object, 50 feet in diameter” for 20 minutes over San Juan, Puerto Rico, until they ran low on fuel and had to return to their base. Many of these incidents would be attributed by officials to atmospheric conditions, weather balloons or other everyday sources, but some remained unexplained.

Between 1983 and 1986, a notable rash of mass sightings occurred in New York’s Hudson Valley, some 50 miles north of New York City. One witness, Kevin Soravilla, a retired lieutenant from the Yorktown Police Department, described a huge, silent craft, 100 yards from wingtip to wingtip, hovering low, which banked and made a 45-degree turn before abruptly speeding off. Soravilla said he called Stewart Air Force Base in nearby Newburgh to determine whether one of its C-5 transport planes—then the world’s largest and heaviest aircraft—had been in the skies that night; none had. Later that year, a hulking triangular UFO hovering over a stretch of New York’s Taconic Parkway prompted a huge traffic pile-up as scores of motorists stopped to get a better look. Similar incidents continued in the region for several years.
‘Exceeded the Limits of Conventional Aviation’
Many witnesses describe what they perceive to be the crafts’ extraordinary abilities. One evening in late November 1989, two police officers on patrol in Eupen, Belgium, not far from the German border, spotted an odd triangular object overhead. In the ensuing days, hundreds of Belgians reported similar UFOs, described in news reports as “a triangular object with a bright red center light” or as a “flying platform” with three huge searchlights.
In March 1990, the Belgian air force sent up two F-16 fighter jets to get a closer look at one triangle that had been spotted on radar. Their onboard computers recorded the object’s remarkable maneuverability and its ability to accelerate from 1,000 kilometers per hour (about 621 miles per hour) to 1,800 kilometers per hour (about 1,120 miles per hour) within seconds. “What the computers registered exceeded the limits of conventional aviation,” a Belgian air force colonel told reporters.
In March 1997, Phoenix, Arizona, became a UFO hotspot when some 30,000 local residents saw something strange in the skies. Some reports said the mysterious object was V-shaped, but many described it as triangular. “It was in a triangle shape and it had three lights. It was moving very slowly,” an 11-year-old Cub Scout was quoted as saying. A retired airline pilot described it as “the size of 25 airliners…and it didn’t make a sound.” Others described it as the size of three football fields.
In 2000, police officers from neighboring municipalities in southern Illinois were called to investigate a trucker’s report of a massive arrowhead-shaped craft hovering low in the sky, two stories high and as long as a football field. Dispatch tapes reveal the shock and awe expressed by the different law-enforcement teams, who were all in radio contact with each other.
The National UFO Reporting Center, which catalogs more than 8,100 sightings of triangle-shaped UFOs since the early 1960s, lists more than 200 in the first half of 2020.
The Truth Behind the Triangles
Many of these sightings have been investigated repeatedly by UFO sleuths. The Belgian triangles have been explained away as stars, planets, balloons or blimps, with a bit of mass hallucination thrown in. The lights over Phoenix were dismissed as flares dropped during an Air National Guard exercise, although that theory has many skeptics. Some say the New York sightings were a hoax perpetrated by local stunt pilots flying in formation.
One explanation raises the possibility of the “airship effect.” That’s the theory that people who see unrelated lights in the sky can trick themselves into believing they are all part of the same object. Three lights? Must be a triangular spaceship. Three lights hundreds of yards apart? Must be a really big triangular spaceship.
Other speculation has focused on top-secret aircraft. Although the U.S. government has largely stayed mum on the matter, it’s common knowledge that the Air Force has experimented with triangular- and V-shaped aircraft for decades, including the B-2 Spirit stealth bomber and the F-117 Nighthawk—and possibly others kept under wraps. Sightings near the clandestine spy plane test facility at Area 51 in Nevada may indeed be connected to test flights of some of these craft.
However, the extraordinary size many witness describe is puzzling. And for Marler and others, the volume of the sightings and the consistency of the crafts’ hovering behavior, combined with their unexplainable sudden accelerations, point away from known military technology.
If not home-grown, then what? One theory suggests that these craft are engaged in mapping sensitive sites. The southern Illinois sightings occurred within one to two miles of Scott Air Force Base, home to U.S. Air Mobility Command, which coordinates all global transportation for American troops. The Hudson Valley sightings happened in close proximity to Stewart Air Force Base. And Mellon has interviewed multiple Persian Gulf veterans who witnessed triangular craft near sensitive military operations. “An adversary planning a future attack would want to know every inch of the battlefield,” he says.
Still, the black triangle mystery persists. “There’s a lot of data,” says Marler. “That doesn’t equate to answers.”

Anti-Gravity Technology Hidden in Nature – Viktor Grebennikov
Anti-gravity Research
For many years, humans have been on a quest to understand the secrets of hyperdimensional physics and uncover the secrets of anti-gravity. Numerous scientists consider anti-gravity technology to be the Holy Grail of the 21st century – a single technology that will radically transform human civilization and begin a new age on Earth and beyond. That such technology is possible is supported by the innumerable UFO videos and sightings all around the planet.
Recently, even the United States Navy disclosed a mysterious footage of a UFO encountered by US navy pilots. According to official data, NASA started its research on anti-gravity technology in 1992. They considered that a device built around a superconductor and a magnet can shield an object from gravity. Declassified documents, however, show that the United States began their anti-gravity research much earlier, as far back as the 1950s.
Many people believe that after the notorious Roswell UFO crash in 1947, the US government began spending billions of dollars on reverse-engineering extraterrestrial technology.
TR-3B Astra – Secret Anti-Gravity Spacecraft
Curiously, the US Secretary of the Navy is listed as the administrator on several radical aviation technologies patented by aerospace engineers. A mysterious man by the name of Salvatore Pais is named as the inventor of four ambiguous patents for which the United States Navy is the assignee: a bizarrely shaped “High Frequency Gravitational Wave Generator;” a “Piezoelectricity-induced High Temperature Superconductor”; an “ Electromagnetic field generator and method to generate an electromagnetic field” that could deflect asteroids, and, perhaps strangest of all, a “Craft Using an Inertial Mass Reduction Device,” described in the patent as a “hybrid aerospace-underwater craft” capable of extraordinary feats of speed and maneuverability in the air, water, and outer space alike, thanks to a revolutionary electromagnetic propulsion system.
While all are relatively outlandish sounding, the latter was personally vouched for by the Chief Technical Officer of the Naval Aviation Enterprise, who claimed the Chinese were already developing similar technologies.
Although the US has not admitted to possessing such a craft, countless people have witnessed a strange triangular UFO in the sky, which looks exactly like the mysterious craft from the patent.
Of course, follow the coordinates on map now, and you’ll find that the mysterious object ( Triangular shape Device) has been hidden from Google Maps, which makes it even more suspicious.
Viktor Stepanovic Grebennikov
No doubt, the world of anti-gravity is one of cloak and dagger, of extra-terrestrial implications and dark money funding. However, the man we’ve dedicated this article to was not a backroom power-player or governmental elite, but an ordinary man in an extraordinary position at the forefront of anti-gravity discovery. He did not accomplish this with billions of dollars or secret government facilities, but simply by observing nature and all its wonderful creations.
Viktor Stepanovich Grebennikov was born in 1927 in Simferopol, a populous city in the Crimean Peninsula region of what was then the Soviet Union. Only a few years before he was born, the city had been an important theater in the Russian Civil War. Grebennikov’s mother was a noblewoman and his father, a simple mechanic, two classes which previously would not have intermingled. For his part, Grebennikov was an intelligent, curious young man, and he became among the first of a new, educated generation.
It was this education that led him as an adult to Novosibirsk, on the southern tip of the Western Siberian Plain. There, Grebennikov took to a wide range of interests, becoming a scientist, specifically an entomologist – which is the study of insects – but also a naturalist, painter, and rugged outdoors man. He may also have been a poet, judging by how he described the natural beauty of the Siberian steppe. As he wrote:
“A quiet evening in the steppe. The sun’s red disk has already touched the faraway, misty horizon. Pods of ducks gleam over the evening lake, sandpipers are also heard in the distance. The high, pearl-colored sky stretches over the calming world of the steppe. How good it is to be out here, in the open country!”
Cavity Structural Effect (CSE)
It was this love affair with nature, far from the stuffy offices and thick books usually associated with scientists, which sent Grebennikov down the path of discovery that would define his life.
It happened almost entirely by chance one evening in the early 1980s. Grebennikov was engaged in his favorite pastime, roaming the vast steppe alone with intent to camp under the stars. As he laid his head on a makeshift pillow, Grebennikov was overcome with an unpleasant feeling – headache, ringing ears, and a metallic taste in his mouth. He realized that he had set up camp on top of an underground bee city, that in fact, in his own words,
“the entire steppe is dappled with their holes like Swiss cheese, and in places, almost like a sponge.”
What could this mean, Grebennikov wondered? He returned to the spot four more times, through varying weather and times of day, and each time found the results the same. He noted that five meters away from the boundary of the bee city, he felt no effects, but as soon as he entered the area, he felt similarly unpleasant. This weighed on Grebennikov’s mind for some time, until years later he happened to be in an area where another bee city had recently ‘died,’ that is, collapsed as a result of erosion and the passage of time.
While investigating the site, Grebennikov collected parts of the nest, the familiar ‘honeycomb,’ and returned to his office. There, he noticed the most unusual phenomenon. When he put his hand over the honeycomb, he could feel a heat emanating from it, a “thermal sensation” which made him light-headed. He got others to try, and they reported similarly, feeling heat or cold wind, having numbness in their fingers or feeling as though their hand was being pushed around.
Most peculiar, the cause of this could not be measured by any traditional scientific device. Grebennikov noted that:
“thermometers, or ultrasound detectors, magnetometers and electrometers-did not respond to them in the slightest,”.
Further, the effect could not be blocked by covering, even with a thick piece of metal. Strangely, clocks – both mechanical and electronic, started running inaccurately when placed near the zone. By chance, Grebennikov had discovered the Cavity Structural Effect (CSE), which is what he called this type of ‘force field’ which surrounded cavernous honeycomb-like objects. Believing this to be an important and potentially groundbreaking discovery, Grebennikov published an article on his findings.
Surprisingly, the article went unnoticed or ignored in the mainstream scientific community. Thus, Grebennikov was left to continue the work himself.
While his status as an entomologist was probably at least partially responsible for the indifference of the scientific community, it was this vocation that allowed Grebennikov his next major breakthrough, a discovery that would change everything.
In 1988, Grebennikov was examining the chitin shells of insects under a microscope, when he noticed what he called:
“an unusually rhythmic, extremely ordered, incomparable honeycomb, solid multidimensional composition, which looked as if it was pressed by some complicated automatic machine.”
Chitin Shells of Insects Magnified by Microscope as he moved deeper into study, something extraordinary happened. As Grebennikov described:
“I was about to place a second identical plate with the same unusual cell structure on its underside, almost purposelessly on top of the first one. But then. The little plate came loose from my tweezers, hung suspended above the other plate on the microscope stage for a few seconds, then turned a few degrees clockwise and swung – and only then it abruptly fell on the desk.
When I came to my senses, I tied a few panels together with a wire and it wasn’t an easy thing to do. I succeeded only when I positioned them vertically. What I got was a multi-layered chitin block and I placed it on the desk. Even a relatively large object, such as a thumbtack, would not fall on it. Something pushed it up and aside. When I attached the tack on top of the “block,” I witnessed incredible, impossible things. The tack would disappear from sight for a few moments. That was when I realized that this was no “beacon,” but something entirely different.”
This incredible discovery got Grebennikov thinking. Science suggested that some bugs should be too big to fly, based on the size of their wings and the speed of their wing beat. Was the Cavity Structural Effect caused by this ‘incomparable honeycomb,’ creating some sort of anti-gravity field, allowing the bugs to defy physics and fly? Were the bugs, in fact not flying at all, but levitating?
Viktor Grebennikov’s Anti-Gravity Platform
Following this line of thought, and the works of past scientists like Nikola Tesla, Grebennikov set about trying to create some sort of anti-gravitational vehicle. For years he toiled, pouring heart and soul into the project, until finally, he came up with something possessing apparently amazing characteristics, Viktor Grebennikov's Anti-Gravity Platform
By attaching hundreds, if not thousands of chitin shells to the bottom of a simple wooden platform, Grebennikov had invented an anti-gravity vehicle which he claimed could travel at up to 1500 kilometers per hour, as many as 300 meters off the ground. He operated the device by stepping on the platform and using two handles attached to the base by a single pole. Despite the incredible speeds, the rider did not experience any effects, no inertia properties, or dynamic pressure, almost as if they were ensconced in a bubble or force field. Further, when in flight, the device was invisible from below, appearing as only a light sphere or cloud in the sky. Observers noticed that even his shadow was missing when in flight, and his watch was constantly shifting forward or backward. We know from Einstein that time, space, and gravity are intertwined.
The Suppresion of Viktor Grebennikov’s Research
Humble in the face of such a potentially world-changing invention, Grebennikov believed that so-called ‘real’ science should investigate his discovery. Thus, he filed for a patent. Shockingly, his patent application was resoundingly denied, while Grebennikov was rejected and called out by skeptics and other scientists.
It certainly didn’t help that he lacked photographic proof, as his camera would malfunction during flights as a result of the Cavernous Structures Effect. But the reception he received for such an apparently groundbreaking invention represented the antagonistic relationship Grebennikov had with establishment thought throughout his career. He was not shy about this, asserting:
“The joy of creative work, even of work that ends in failure, is far higher and brighter than earning any diplomas, medals, or patents,”
Viktor Grebennikov's Book - My World
But perhaps the reception to Grebennikov’s invention went beyond mere antagonism. In 1992, his patent application having been rejected, Grebennikov sought to publish a book detailing his discovery, the principles, and measurements of his invention backed by a litany of full color images. It was said this would include photographs of a demonstration of the machine Grebennikov gave at a museum. However, just before the book was released, the publishers, possibly at the behest of authorities, undertook dramatic edits of the book, removing hundreds of pictures and all schematic details.
Why, at the same time Grebennikov was being called out by skeptics, was evidence of his invention being subverted?
According to a long time colleague, Grebennikov was part of a so-called scientific underground that was persecuted and victimized by the scientific establishment and governmental authorities. Given the money governments were admittedly and allegedly spending in pursuit of the secrets Grebennikov had apparently discovered, it is perhaps no surprise his discovery would be suppressed.
Anti-Gravity Technology in Ancient Times?
Maybe Grebennikov had inadvertently stumbled across something more powerful, and thus more dangerous than he could have imagined, a deep and almost mystical power sought by humans for centuries, dreamed about with every UFO sighting or unexplained human artifact.
Consider the Great Pyramid of Giza in Egypt, a structure so incredible that generations of deep thinkers have speculated how an ancient society could have created such a thing. It is a mystery so inexplicable that some have suggested the ancients must have had access to some sort of alien technology.
Electromagnetic Energy from the Pyramid of Giza
This might not be fetched as it sounds. Recent research shows that the Pyramid centralizes and conveys electromagnetic energy into the inner chambers and towards the top, as in Grebennikov’s honeycomb. Further, where chitlin shells from bugs powered Grebennikov’s flying machine, the beetle was a vitally important symbol in Egyptian mythology, often depicted in art and icon.
Scarab Beetle Egypt
Alien or not, it appears the Egyptians may have had access to a knowledge since lost to human beings, thirsted by governments, and rediscovered by Grebennikov centuries later.
What exactly Grebennikov discovered is unknown to this day. It may sound incredible, but the mysterious usually does until it becomes a reality. Before his death in 2001, Grebennikov left us with these words:
“There is no mysticism, the thing is simply that we, humans, still know little of the Universe which, as we see, not always “accepts” our, all too human rules, assumptions, and orders.”
