Patent ID: 7080509

Claim:
A method, by which driving-thrust can be originated, including the steps: (a) Arranging in tandem a number of rotating frames that form radial array, each frame includes two units of weights at its mid-section and one cylinder at each end of the frame, each cylinder includes pistons, which are adapted to create vacuum in the bottom cylinder with units of weight, which are lighter than the units of weight said vacuum could lift; (b) Having gas between the pistons in each cylinder with less pressure than the atmospheric pressure, adapted to flow from the bottom cylinder to the upper cylinder; (c) Reducing the atmospheric pressure in the respective cylinder, as it rotates upwards; (d) Pushing the respective piston down in the bottom cylinder and pulling-up the respective piston in the upper cylinder with the respective unit of weight; (e) Locking the elevated piston in the upper cylinder; (f) Creating vacuum in the bottom cylinder and setting the locked piston in the bottom cylinder free to be elevated with the other piston in the bottom cylinder and with the lower unit of weight; (g) Lifting the two pistons in the bottom cylinder with the lower unit of weight, so as to unbalance the cylinders and force them to maintain their rotational driving thrust.
