"The invention discloses a superconducting electromagnetic field sphere antigravity propelling device which comprises a shell, a partition plate, a strip-shaped superconducting magnet, a magnetic shielding cylinder, an upper section stress wall, an upper section annular conductor group, a lower section stress wall and a lower section annular conductor group. The current of the upper section of the annular conductor set flows clockwise, each point of the conductor generates an ampere force deviating from the center of the shell in the electromagnetic field, and an upward resultant force is formed to act on the upper section of the stress wall to form an upward thrust. The current of the lower section circular ring conductor group flows anticlockwise, each point of the conductor generates an ampere force pointing to the center of the shell in the electromagnetic field, and an upward resultant force is formed to act on the lower section stress wall to form an upward thrust. The two upward thrusts act on the device together, thereby offsetting the influence of gravity and enabling the device to have the capability of antigravity propulsion. The invention can freely go in and out of the earth's atmosphere without depending on the propulsion of the acting force and the counterforce of the air, can also keep static in any space, gets rid of the dependence on conventional fuel and air, and can meet the aim of flying in the space for a long time."

"The invention discloses a mercury sphere antigravity propelling device which comprises a shell, an insulating partition, a strip-shaped super-conductive magnet, a positive electrode wall, a negative electrode wall, a buffer layer, an annular insulating cambered surface, a first capacitor and a second capacitor. The positive electrode wall, the negative electrode wall, the insulating partition and the annular insulating cambered surface form a closed annular channel, and 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 invention can freely go in and out of the earth's atmosphere without depending on the propulsion of the acting force and the counterforce of the air, can also keep static in any space, gets rid of the dependence on conventional fuel and air, and can meet the aim of flying in the space for a long time."
