Anti gravity system
"An anti gravity system with a hallow metal sphere (7) placed inside a very strong hallow outer metal sphere (1) with a clearance in between the two and the outer sphere having a sump at bottom, the clearance (8) between the spheres filled with mercury or lead, the sump (2) having an electric resistance coil (3) connected to a generating unit (4) via a transformer generates high temperature in the matter in between the spheres and a force is applied on the inner face of the outer sphere by the inner hallow sphere and the system looses its weight depending on the temperature."
"An "Anti Gravity System" comprising a hallow sphere [ 1] with sump [2] at bottom with electric coil [3] fixed in the sump said coil connected to a electric generator unit using fossil fuel or fuel cell using hydrogen [4] via a transformer [5] and a switch [6] is also provided in the circuit said electric coil [3] is passed through an insulator material and the said coil [3] will not touch the outer sphere material, another hallow sphere [7] is placed inside the Baid outer sphere [I] and the clearance between the two spheres [ 1] and [7] is filled with 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."

"Radar images of the UFO show a solid ball, measuring about 6 feet (2 meters) in diameter, flying at speeds of 46 to 158 mph (74 to 254 km/h). Its flight lasted over an hour, culminating with the sphere vanishing beneath the waves. No wreckage was found at the location where the object went down."
