Magnetics as the Future of Propulsion?

I wish this theorist would build a small prototype to show his ideas as feasible. Imagine the intensity of magnetic fields needed for the kind of propulsion he describes, based on the field strength of earths magnetic field as we currently know it.

"Advanced Magnetic Propulsion Systems - Firstly I need to explain scientific foundations behind two most basic terms used in research on propelling devices. These two terms describe two basic kinds of propelling devices, namely the so-called "motors" and the so-called "propulsors".

Motors produce only a relative motion of one group of parts of a given machine, in relationship to other group of parts of the same machine. This means that motors are practically unable to produce the absolute motion of entire objects in relationship to the environment of these object, although they frequently provide mechanical motion that is later used to create such an absolute motion.

As an example consider a car, in which the engine is a typical "motor". Everyone knows that the engine from a car DOES NOT produce the motion of the entire car along a road - but these are wheels which produce this motion. The engine from a car supplies only the mechanical energy to wheels. So a car is a machine which contains both, a single motor (i.e. the car's engine) which causes the relative rotation of wheels in relationship to the car's body, and four propulsors (i.e. four wheels) which produce absolute motion of the car along the road. Similarly is with a boat.

A "motor" in a boat only reassures the relative rotation of propeller, while the absolute motion of the entire boat is formed by this propeller, not by the motor.

Devices which produce an absolute motion of entire vehicles in the surrounding environment are called propulsors. Examples of propulsors include: a propeller in an aeroplane, helicopter blades, jet engine, rocket engine, hovercraft outlets, wheels, propeller in a boat, and many more. Notice that propulsors must be distinguished from so-called linear motors.

For example railway locomotive is just simply a linear motor, not a propulsor. This is because propulsors produce an absolute motion in the natural environment. In turn linear motors produce only a relative motion in relationship to one of their part (e.g. a "rail") that is extended at large distance."
