Abstract: In a propeller pump for an aquarium, starting-up of the rotor in the correct direction of rotation is guaranteed through the fact that a unit, which is formed by the propeller and the rotor of the pump, is disposed on a spindle in an axially displaceable and rotatable manner. If starting-up occurs in the wrong direction, said unit, and thereby the rotor, is drawn axially out of the magnetic field of the stator until the magnetic coupling between said stator and said rotor is no longer sufficient for further driving in the angular direction. The unit formed by the rotor and the propeller is then drawn back into the stator again by axial magnetic components of force, where a fresh opportunity of starting up again is imparted to it. It is guaranteed that the rotor will revolve in the correct direction after, at the latest, a few attempts at starting up.

Abstract: The concept behind the ZEE (zero emission engine) is rather than using fossil fuel combustion it's using electronic controlled magnets for propulsion. On the first stroke or up stroke it's going to use positive and negative to pull the piston to the top of the stroke when it reaches the top of the stroke the computer is going to switch it to positive and positive to force the piston down. And with every stroke spinning the crankshaft turns the power generator to make it's own power. When the throttle is pressed the crank starts to turn at first using the power stored in the battery's the first rotation starts the power generator making it's own power and at the same time the throttle being pressed tells the computer to speed up the switching of the Electronic controlled magnets getting a faster Rpm ( rotations per minute) When the brake is pressed the computer tells the electronic controlled magnets to slow down the switching process to help slow down the vehicle.
