Electrogravitics is based on Tesla’s work , and is concerned with producing a polarized field or charge around an object, which can then have its mass reduced quite markedly as a result. As effective mass is reduced (or nullified), it is able to be propelled with very little energy .
This is likely an elementary electrogravitic device constructed by Earth scientists:
While Wikipedia says that “The field became popular in the mid-1950s, but rapidly declined in popularity within mainstream science after a startlingly successful demonstration of Brown’s “tethered disks” to an audience that included U.S. military observers.” , it is hard to imagine that it ‘declined in popularity’ after such a successful demonstration of levitation, which even today would seem magical. Likely, the technology was sequestered from the public domain and used in clandestine efforts by black ops projects. As The Orion Project intimates :
Developed by T. Townsend Brown, Dr. Biefeld at Princeton (who worked with Albert Einstein) et al., these systems have been studied and reproduced by various scientists over the years. In the highly classified aerospace industry, such flying devices were dubbed ‘Flux Liners’ because they used the Quantum Vacuum Flux field to provide energy and propulsion. The early Aerospace prototypes used only a 24-volt marine battery as a power-up system, after which the device went ‘over unity’, drawing its power from the Quantum Vacuum of space.
One well-known example of military use of electrogravitics is the B-2 Stealth Bomber. From Above Top secret:
Ever since the B-2 was officially declassified many odd things were noticed about the plane and it’s program.
- Many people are amazed how quiet the B-2 is during take-of
- It’s official operating speed is not declassified.
- First the USAF said Chemicals are added to the exhaust to cool the exhaust, but later they admitted, it is to prevent the forming of contrails.
- Both its wing leading edge and jet exhaust stream are charged to an incredibly high voltage.
- A few USAF publications by Wright Aeronautical Laboratory and Air Force Systems Command’s Astronautics Laboratory about the B-2, are about topics as ‘electric-field propulsion’, and ‘electrogravitics’ (or anti-gravity), the transient alteration of not only thrust but also a body’s weight.
And from scribd.com:
“For one, what people don’t generally know is that this craft has an electrogravitic propulsion system that not only eliminates drag by more than an incredible 60% but can travel at great speed on a ‘gravity wave’ without conventional propulsion! In a nutshell,what this system does is to produce a gravity ‘well’ or ‘gravity gradient’ in front of the craft.”
Once this technology is released from behind the military black-ops curtain, The Orion Project conjures up possibilities where our imagination might be lacking:
“Once fully developed, this technology will enable cars, trucks, aircraft and ships to move in the air silently, without the use of conventional engines that use oil, diesel or gas. Surface roads will become unnecessary, saving untold billions of dollars in road and bridge building and maintenance worldwide – and freeing millions of prime acres of land for agricultural and recreational uses. Aerospace applications will enable humans to travel vast distances in space without the need for a fuel payload or rocket engines.”
