"The plasma, mercury based, is pressurized at 250,000 atmospheres at a temperature of 150 degrees Kelvin and accelerated to 50,000 rpm to create a super-conductive plasma with the resulting gravity disruption. The MFD generates a magnetic vortex field, which disrupts or neutralizes the effects of gravity on mass within proximity, by 89 percent"

"a liquid metal mercury or solid low temperature melting material like lead [8] so as to get maximum lifting force, the outer face of the inner sphere [7] and the inner face of the outer sphere [ 1] are coated with material which is highly resistant to temperature and non conductor of heat.
2] The "Anti gravity system" as claimed in claim [ 1] looses it's weight when heat is generated in the said electric coil due to which the matter in between the said spheres is heated to a high temperature and a force is applied on the inner face of the said outer sphere by the said inner hallow sphere and the said system looseβ it's weight depending on the temperature."
"The said "Anti gravity system" as claimed in claim [ 1] looses it's weight when the temperature increases and the dynamic pressure increases in the said liquid metal and said pressure tries to push the said inner hallow sphere to the center of the βaid outer hallow sphere and the βtatic hydraulic forces which exist before the application of heat cease to exist."
"Buoyant force is a powerful force in nature which actB opposite to gravitational force. If we combine these two laws we arrive at a system as βhown in FIG[ 1] in which there exist an outer hallow sphere and an inner hallow sphere is placed inside the outer sphere and water is filled in between the two. The inner hallow sphere applies a buoyant force over the inner face of the outer sphere equal to the weight of water displaced by the inner sphere. But if we weigh this system weight is not changed, This is due to the additional hydraulic forces acting in the system.Now let us imagine what happens when heat is supplied to the water in between the two spheres. The temperature of water is gradually increased and when it exceeds the boiling point of water pressure increases in the system and the pressure tries to push the inner hallow sphere to the centre of the outer hallow sphere. At this moment the hydraulic forces of the system cease to exist. When the temperature increases the inner sphere applies a force over the inner face of the outer sphere and the system now looses it's weight depending on the pressure and temperature of the matter in between the hallow spheres and the system is called the "anti gravity system"."

"a certain amount of mercury is filled in the annular channel. After the power supply is switched on, the mercury rotates anticlockwise at high speed under the action of electromagnetic force, and thrust in a direction deviating from the center of the shell is applied to the wall surface of the whole negative electrode due to centrifugal action. The direction of the total thrust is opposite to that of the gravitational pull, so that the influence of the gravitational pull is counteracted, and the device has the antigravity propelling capacity"
"The electromagnetic fluid propulsion principle is that electromagnetic force generated by interaction of a magnetic field and an electric field acts on a conductive fluid to promote the conductive fluid to move at a high speed so as to generate certain type of propulsion, and the common conductive fluid comprises gaseous plasma, liquid metal or electrolyte and the like. The application of electromagnetic fluid propulsion technology to conventional power devices is to artificially ionize gas at high temperature into gaseous plasma, and the gaseous plasma forms supersonic airflow to be sprayed to the outside through the principle of electromagnetic propulsion so as to obtain reverse propulsion. This method requires continuous consumption of fuel or raw material for gas generation, and cannot meet the purpose of long-term flight in space, and therefore, an unconventional power plant for interplanetary navigation needs to explore a new electromagnetic fluid propulsion system. In order to prevent the fluid accelerated by the electromagnetic field from being consumed, the high-speed fluid can rotate in the closed space in the device, and the fluid in the rotating motion is necessarily subjected to the action of a centrifugal force field departing from the rotating center. When the centrifugal force field and the universal gravitational field applied to the rotating fluid are different in direction and large enough, a resultant force field opposite to the universal gravitational field is formed between the centrifugal force field and the universal gravitational field, and therefore the whole device has the capability of antigravity propulsion.
The design and development of the antigravity propulsion device based on the theory must consider the following problems: the method comprises the following steps of firstly arranging a magnetic field and an electric field, secondly designing a structure of an acceleration channel of a closed space, thirdly selecting an acceleration fluid and fourthly implementing means of an antigravity propulsion mechanism."

"Negative mass would possess some strange properties, such as accelerating in the direction opposite of applied force. Despite being inconsistent with the expected behavior of "normal" matter, negative mass is mathematically consistent and introduces no violation of conservation of momentum or energy. It is used in certain speculative theories, such as on the construction of artificial wormholes and the Alcubierre drive."
