Lifter Flight-Test Compilation Footage

This footage is some of the hundreds of video tests we shot of antigravity "Lifters" being tested by Tim Ventura & American Antigravity during the early 2000's.

Between 2002 and 2004 we tested over 100 different models of "Lifters", which utilize some combination of Ion-Wind and the Biefeld-Brown Effect to provide propellant-less thrust. Lifters are powered by a high-voltage pulsed-DC power supply producing approximately 50,000 to 10,000 volts.

The voltage crosses an air-gap between a corona-wire and foil skirt around the bottom of the lifter, and creates a resulting net directional thrust that requires no fuel for propulsion.

While both ion-wind and the Biefeld-Brown Effect have been popular topics for decades, Lifters became very popular in the early 2000's after detailed instructions & test footage appeared on Jean-Louis Naudin's JLN Labs website.

Bruce Maccabee on UFO's

We’re joined today by Dr. Bruce Maccabee, an optical physicist formerly with the U.S. Navy, and a leading ufologist. Bruce has been a ufologist since the late 1960s when he joined the National Investigations Committee on Aerial Phenomena.

Over his long career in ufology, he has authored scores of technical papers and hundreds of articles on the topic, and in the process become one of the most respected UFO investigators in the world.

Our discussion in today's interview is focused on the history of UFO research that Bruce describes in his latest book, "UFO/FBI Connection: The Secret History of the Government's Cover-Up", available online at

In short, Bruce has spent literally decades investigating UFO's, starting back in the 1960's when he joined NICAP, and continuing over the next 50+ years up to contemporary, present day research. He's explored some of the most exciting UFO cases in history, such as the Kenneth Arnold sighting in 1947, generally regarded as the first widely reported UFO sighting in the United States.

The experience that Bruce accrued throughout his career, along with the scientific knowledge he applied from his background as a PhD physicist, led him to be a highly sought-after figure by government officials looking to understand more about UFO's. In addition to discussing his own experiences investigating well-known sightings, we also explore his interactions with government, and how he came to be the first person to ever see the FBI's "Real Life X-Files".

Greg Henderson on the Hendo Hoverboard

We’re joined by Greg Henderson, the co-founder of Arx Pax – the company developing the Hendo Hoverboard. What his firm has achieved is a true breakthrough in advanced propulsion – because not only have they created a stable, self-propelled, levitation platform with no external power source, they've also begun to successfully market & commercialize this technology as well.

The Hendo Hoverboard isn't quite the device you remember from the movies: the Hendo Hoverboard only levitates over a conductive surface, and the early prototypes emit a distinct humming noise during operation. It's power-hungry as well: the operating time of today's prototypes is approximately 7 minutes when carrying an adult passenger. However, what the Hendo Hoverboard has achieved is to reach the commercial marketplace, which is a goal that thousands of innovators have fallen short of in breakthrough propulsion for decades.

Greg Henderson discusses his initial inspiration for the Hendo Hoverboard as coming from research aimed at improving the structural integrity of buildings in geologically unstable, earthquake-prone regions of the world. Rather than provide cushioning for the building's foundation with liquids, he was struck with the notion of stabilizing the building using magnetic fields - and his research led him to what he calls "Magnetic Field Architecture" - the key principle behind the Hendo Hoverboard's implementation of inductive levitation.

After self-financing his research into this technology for years, Greg describes running out of funds - and turning to venture-capital to provide valuable assistance in creating a commercially-viable product. But how do you market an innovative new levitation technology in a way that makes it understandable to the average person? Henderson bet on recreating a fictional technology that everyone was already very familiar with: the Hoverboard.

Greg, along with his wife and co-founder Jill Henderson, have launched a kickstarter campaign on their Hendo Hover website - with the goal of raising $250,000 for the project. So far they've raised over $424,750 and have 2,608 contributors - which is hopefully a sign of early market acceptance of their product. In this interview, Greg discusses how the science of advanced propulsion has worked successfully in the commercial marketplace for a startup success story unlike any other.

John Brandenburg on Poynting Vector Antigravity

Dr. John Brandenburg joins us to discuss how the "Murad-Brandenburg Poynting Field Conservation Equation" may offer insights into recent antigravity experiments involving rotating magnetic fields. In particular, he describes how his work serves as a theoretical basis for antigravity experiments by Paul Murad and Morningstar Applied physics which used a device similar to a Searl Effect Generator to produce a repeatable net loss in weight between 7% to 20%.

Brandenburg is a Theoretical Plasma Physicist working on particle astrophysics, a fundamental quantum theory of gravity, and the GEM Unified Field Theory, explains how the theoretical research that he developed through Morningstar Applied Physics led to a novel approach to Poynting-Vector propulsion which may also help validate the claims of Searl, Godin & Roscshin, and others.

In Brandenburg's GEM Unified Field Theory, he describes finding what he calls the "Vacuum Bernoulli Equation", in that it is analogous to the more traditional aerodynamic effect. What he found in the theory, which is a synthesis of Kaluza-Klein, hidden-dimension theory, and Sakharov's radiation-pressure theories, that the Poynting Vector became very important in facilitating the control of gravity and generating antigravity effects. In this theory, it is not only the Poynting Vector itself that is important, but also the difference in Poynting Vectors, which generates a curvature leading to these effects.

He also discusses a paper entitled, "The Murad-Brandenburg Poynting Field Conservation Equation and Possible Gravity Law" (below) that he co-authored with Paul Murad, and how this led the Morningstar Applied Physics team to assert that local gravity can be affected by creating a "vortex" of pointing vectors, and that by mechanically rotating a series of Neodymium-Iron-Boron magnets in a circular manner they were able to produce an antigravity effect of 7% to 20% of the total weight of the test apparatus, which weighed around 200 pounds.

John describes the Le Sage - or "push" gravity as being an effect resulting from zero-point field flucations with matter, and indicates that the Poynting Vector was initially connected with gravity in this model by none other than physicist Dr. Andrei Sakharov, the father of the Soviet fusion bomb. According to Brandenburg, Sakharov's research into energy propogation in the watermelon-shaped enclosure of the bomb led him to the conclusion that Poynting Vector energy was creating a million-fold increase in gravity in the heavy hydrogen, causing it to collapse and fusion to occur.

In essence, then, gravity is explained by Brandenburg as consisting of a ZPF radiation pressure synomymous with that used to propel a solar sail, except that in the case of gravity what creates motion is a shielding effect that occurs in the direction of other particles with mass. According to Brandenburg, this model of gravity is not only a consistuent of his own GEM theory, but also a component in Hal Puthoff's research as well, and he describes Puthoff as filling in the gaps in Sakharov's original hypothesis, providing greater theoretical detail on exactly how this model may influence gravity, especially in terms of how neutral particles respond to Poynting radiation as a result of the electric charge in the quarks that they are composed of.

Paul Murad's Searl Effect Generator

Paul Murad joins us to discuss a variant of the Searl Effect Generator that generates a 7% decrease in weight in steady-state rotation with as much as a 20% decrease in weight during transient testing. The design is based on a combination of features from both John Searl’s classic SEG along with several new modifications resulting from Sergei Godin & Vladimir Roshchin’s Searl Effect Generator experiment in the 1990′s, and also featured a number of new enhancements such as use of a ferromagnetic fluid in the ring-roller system to simplify construction & reduce cost.

Paul Murad is an aerospace engineer and retired science and technology analyst for the United States Government, and also served as the Section-F Chairman at the ISNPS STAIF Conference for many years. He is currently engaged as the CEO of Morningstar Applied Physics, a startup focused on exploring innovative new approaches to energy & propulsion technologies.

Ed McCullough on Lunar Colonization

Space and nuclear engineer Ed McCollough joins us to discuss lunar & space colonization. Ed is an Associate Fellow at the American Institute for Aeronautics and Astronautics, and the former Chairman of the AIAA Space Colonization Technical Committee and Board of Trustees at the University Space Research Association. He's also formerly the Section-E Chairman of the ISNPS STAIF Conference, which focused on innovative approaches to colonizing space.

McCullough has spent considerable time on a proposal to construct a lunar dome measuring 25 miles in diameter and up to 5,000 feet tall as a means of engaging mankind in commercially viable lunar colonization. His plan, based on decades of engineering experience and collaboration with numerous aerospace industry scientists, is claimed to be achievable with today's technology with a construction time of only 15 years, after which the lunar colony would become commercially self-sustaining and able to sell beamed solar power back to the Earth as a means of paying for itself.

In McCullough's vision, lunar colonization would begin with an underground human habitat in which colonists would manage automated fabrication and assembly machinery to create the required components for a pressurized dome. McCullough discusses the specifications of the dome, as well as many of the challenges associated with lunar colonization - which including finding suitable gases to provide such a massive dome with a breathable atmosphere, as well as how to overcome the issue of micro-particular lunar regolith, which can damage space suits and cause respiratory issues if inhaled.

Water can be produced in mass quantities as steam simply by heating the lunar regolith, and reduced to O2 and H2 as required. Nitrogen, as indicated by LCROSS data, can be produced from ammonia found in lunar craters - and ammonia is also useful, says McCullough, as a stable propellant that does not require cryogenic cooling for storage.

In addition to providing valuable opportunities to harvest solar power, lunar colonization offers the opportunity for sensitive particle detectors for high-energy physics research, along with an excellent platform as a production facility for materials to be used in exploration deeper in the solar system. The chief advantage of lunar fabrication of spacecraft components, indicates McCullough, is the reduced energy required to move those components into orbit for eventual launch on a variety of missions throughout the solar system.

While Ed McCullough's description of the applications of lunar colonization is detailed, he has taken significant real-world steps towards developing a program to realize this scientific and technical vision. He describes past projects launch a real-life lunar colonization mission, and his efforts to assemble the engineering talent and funding to undertake a real-life lunar colonization project in the near future.

Eugene Podkletnov on Antigravity

We're joined by Dr. Eugene Podkletnov to discuss recent (2004 to 2013) experimental antigravity research in gravity modification and superconductors. For nearly two decades Dr. Podkletnov has been researching the link between gravitation and high-temperature superconductors, and just recently published the peer-review results of new experiments he's conducted to measure the speed of a force-beam projected by a stationary superconducting apparatus he's developed.

Podkletnov is well-known for his experiments involving YBCO superconductors, which produced a gravity-shielding effect that was investigated by NASA and has been the subject of many peer-review papers. He describes continuing his experiments in this area, and indicates that he has made continuing progress in creating an antigravity effect that partially shields the mass of objects placed above the rotating disks.

Dr. Podkletnov also describes his "force beam generator" experiment in detail, and provides insights into improvements that he's made over the last decade to increase the force produced by this experimental gravity-beam. The force beam is generated by passing a high-voltage discharge from a Marx-generator through a YBCO emitter suspended in a magnetic field, and Podkletnov has described it as being powerful enough to knock over objects in the lab, as well as capable of being tuned by even punch holes in solid materials.

Podkletnov recently published a peer-review paper on the force beam experiment entitled "Study of Light Interaction with Gravity Impulses and Measurements of the Speed of Gravity Impulses" along with co-author Dr. Giovanni Modanese, and describes the findings of his study, which involved measuring the speed of the force-beam using two separate, but cross-correlated measurement techniques. After careful testing, Podkletnov has found the speed of the antigravity impulse to be approximately 64 times the speed of light (64c), which he indicates does not conflict with modern interpretations of Relativity Theory.

In addition, Podkletnov describes an antigravity effect generated by rotating magnetic fields that requires no superconductors to be generated, and suggests that it may provide an economical tool for future space & energy research.

Frank Znidarsic on Antigravity

Frank Znidarsic proposes a novel method for generating antigravity and cold fusion effects through the application of radio-frequency stimulation of superconductors, as described in his new book, "Energy, Cold Fusion, and Antigravity", which provides a detailed overview of Znidarsic's latest research.

Frank discusses the electrical and magnetic force, and describes magnetism as being a "non-conserved force" in that a ferrite core placed within a magnetic field serves to strengthen the overall magnetic field in an additive way. Similarly, Znidarsic hopes to find an equivalent material to the "ferrite core" that would serve to stengthen a gravitomagnetic field, and thus allow the weak force of gravity to be manipulated on a scale useful for engineering applications.

Zdnidarsic is perhaps best known for his participation in the NASA test-replication of Dr. Eugene Podkletnov's disk experiment, in which a specially constructed superconducting YBCO disk was rotated at high-speed to generate a "gravitational shielding" effect described by Podkletnov. Unfortunately, due to mechanical issues related to the construction and rotation of the fragile disk at high-speeds, NASA was unable to validate Podkletnov's claims, but as an investigator Znidarsic continued to pursue a physical explanation to what Podkletnov claimed to have seen.

Beginning with calculations based on experimental data collected by Podkletnov, Zdnidarsic describes his development of an experimental model involving nuclear transition states that not only predicts effects similar to those outlined by Podkletnov, but also predicts the frequencies of the atomic spectrum using only classical calculations. From this, he infers the coupling of gravitation and electromagnetism to be stronger in the gravitomagnetic field during periods of atomic jumps between energy states, and suggests that this can be harnessed to intensify the antigravity effects to usable levels.

Dennis Bushnell on Space Exploration

Dr. Dennis Bushnell, Chief Scientist at NASA Langley Research Center, joins us to discuss the scientific and technical challenges faced by NASA in planning future manned missions to Mars and beyond. He describes the National Space Exploration Vision, which cites human expeditions to Mars, and indicates that cost and safety are the two major obstacles faced by NASA in realizing this vision.

According to Bushnell, hexavalent chromium in martian dust, interstellar radiation, and lengthy trips in a microgravity environment damage the immune system of astronauts and increase their risk for cancer, which is caused by both radiation and chromium VI. He indicates that the best probability for minimizing these risks comes from dust-filtration research currently being undertaken at NASA as well as in finding new methods of propulsion that should shorten trip times and therefore reduce radiation & microgravity exposure by astronauts.

Bushnell describes research into launch-assist technologies such as magnetic accelerators and the space elevator that may assist future spacecraft in reaching orbit with less fuel, and describes advanced propulsion technologies such as aneutronic fusion and antiproton drives that may provide higher specific impulse. By combining these technologies along with lean ground crews to reduce NASA's "standing army", Bushnell suggests that not only could the cost of space travel be cut substantially but safety could be improved as well.

In addition to aneutronic fusion research, Bushnell also describes recent interest by NASA in Low-Energy Nuclear Reactions (LENR), more commonly known as "Cold Fusion" as discovered by Pons and Fleischmann in 1989. According to Bushnell, experiments over the last 23 years have led to a substantial body of evidence that supports the existence of LENR effects, which he hopes may be harnessed to provide power for future spaceflight.

Bushnell also briefly describes robotic missions to Mars, and the idea of "Robots as Mankind's Children" as proposed by Dr. Hans Morovec and popularized by Ray Kurzweil. According to Bushnell, the 21st century will be dominated by virtual telepresence, and advances in robotics may provide us with the ability to explore Mars remotely in a virtual environment so real that explorers wouldn't be able to tell the difference. The only question remaining is whether robot exploration diminishes mankind's achievement, which Bushnell doesn't believe to be the case.
