|On the Verge of Antigravity|
Achieving true antigravity has been the "Holy Grail" of many propulsion researchers and experimenters since man first dreamed of flight. It's the aeronautics equivalent of the alchemist's quest to turn lead into gold. True antigravity would revolutionize air travel and space exploration. But is it possible? Or is it an impossibility that renders all such research fruitless and pointless? It's worth remembering that less than 100 years ago, space travel, not to mention going to the moon, were deemed impossible by much of the scientific community.
Tim Ventura, among other "fringe" researchers, is experimenting with a fascinating propulsion energy that can make lightweight vehicles called "Lifters" float in the air. Exactly how it does this is largely unknown. (You can see video clips of Lifters in action at Tim's American Antigravity website.)
Although Lifters might not qualify as true antigravity, the theories and research surrounding this amazing technology could, in fact, lead to antigravity vehicles that would change the world. We recently spoke with Tim Ventura about his research.
Q: At American Antigravity, you're doing some interesting research and experiments with devices you call "Lifters" - triangular constructions that seem to defy gravity. What are Lifters?
Tim Ventura: Lifter technology is a new type of field-effect propulsion technology that provides thrust without expelling mass. The Lifter is a "proof of concept" device for the validation of the Biefeld-Brown effect [an electromagnetic force exerted on a capacitor when it is charged with electricity]. There has been speculation that this is either an ion-wind phenomena, a gravitational/inertial phenomena, or some other type of "field-effect propulsion" device (an umbrella term for "unknown"). More and more information points to ion-wind. However, from what I have seen, even the concept of ion-wind is poorly understood.Q: How did you become involved with this technology? How long have you been working with it?
TM: I became involved with the Lifter in March,  as a replication of the information on Jean-Louis website [The Quest for Overunity]. Since then, I have diverged somewhat and investigated several other ideas. Previously, I did several years of research into this and other related phenomena both in college and independently, between 1992 and 1995. My previous research involved Biefeld-Brown, but I didn't have the outstanding success of actual liftoff that Jean-Louis had with the Lifter. His replication of the Lifter was quite ingenious, and none of this would have gotten off the ground without him.
Jean-Louis's experiment was also a replication of work done by Jeff Cameron's team at Transdimensional Technologies in Huntsville, Alabama. I have links to his website as well as the sites of several other experienced and intelligent experimenters. I frankly wish that I had the room for more links, as there are so many gifted people working on this at the moment that I cannot even begin to keep track of all the URLs floating around. Transdimensional Technologies is working on several advanced variations on Lifter technology, although I am not entirely sure how their research is coming along.Q: You say on your website that, strictly speaking, the effect is not true antigravity? Can you explain?
TM: "True" antigravity propels in only one direction (presumably) - straight upward. The Podkletnov apparatus and De Aquino apparatus designs would satisfy this requirement. The Lifter has directional propulsion in a line up through the center axis of the triangle - tilt the triangle sideways, it flies sideways. Therefore, while it may be interacting with gravity, it still has weight and mass. I've actually noticed some effects on the Lifter that suggest that it actually changes inertial mass during flight and possibly not gravitational mass.
Conventional physics traditionally holds that gravitational and inertial mass are equivalent. However, my experiments reinforce the very new hypothesis that perhaps these two properties are not equal at all times. Only very recent physics even suspects that this is the case, and my physics training does not support this belief. However, I cannot deny the experimental evidence that I've seen, which shows a change in inertial mass during flight without (apparently) a change in gravitational attraction.

TM: The conventional ion-wind theory is that air-molecules carry high voltage charges from the emitter wire to the foil and hence satisfy the F=MA equation. However, there are many side effects associated with the high voltages - and indeed the Lifter itself - that seem to suggest something more or perhaps different than this very simple explanation. I don't usually talk about them, but I have included a description of some of them in a PDF called "Electromagnetic Field Anomalies." I've personally encountered very strange effects, such as disappearing signals and magnetic fields.
With regard to method of operation, there are two definite requirements:
- Capacitance across an air-gap
- Charge transfer across an air-gap
A good example of an anomalous effect is that the Earth's magnetic field seems to disappear for a 20-foot radius around the Lifter during operation during and for about 10-minutes after operation. Another good example is that I am unable to pick up the flyback-transformer on a EM-frequency meter during operation. Since the Lifter and power-leads should be acting like an enormous antenna for this, I am amazed that a 250-watt power-supply cannot be picked up standing six feet from it on a device that is sensitive enough to pick up electronic eavesdropping devices (bugs) that use only 1/20 watt.
Q: The Lifters youve constructed look very light. How much do they weigh? And, presently, what is the maximum lifting capacity you have achieved?
TM: The Lifters are very lightweight in construction. Once again, this is a proof-of-concept idea and not a finished product by any means. The typical single-cell Lifters weight approximately 2 to 3 grams; the larger Lifters might weight up to 55 grams (Russell Anderson's 6-foot beamship design). In terms of a comparison, we are getting perhaps a maximum of three times the efficiency of Deseversky's ionocraft from the 1950s, or perhaps one-third the efficiency of a helicopter. The efficiency ratio is perhaps between 1 and 2 pounds of lift per horsepower at this point, maximum.
Q: What lifting capacity do you think is possible? Is the capacity dependent on the power input?
TM: Lifting capacity depends on the power-input. Once again, the peak efficiency is currently between 1 and 2 pounds per horsepower.
