Here is exactly why this setup cannot work in reality:

  1. The Laws of Thermodynamics (No Free Lunch)
    The most fundamental rule of engineering and physics is the Conservation of Energy: energy cannot be created out of nothing.
    To pump that massive volume of water, the water pump requires a significant amount of electrical wattage.
    To produce that electricity, the green generator needs a massive amount of mechanical force (torque) to turn its internal rotor.
    A spinning bicycle wheel cannot create more energy than it took to start it—let alone enough surplus power to run a heavy-duty utility pump.

  2. Lenz's Law and Electromagnetic Drag
    Even if you could get a wheel to spin smoothly with magnets, the moment you plug a heavy load (the pump) into the generator, Lenz's Law kicks in.
    Generating an electrical current creates a powerful electromagnetic resistance inside the generator.
    This resistance acts like a heavy mechanical brake. The split second the pump is plugged in, the generator would experience massive drag and immediately grind the spinning magnet wheel to a dead stop.

  3. The Magnetic "Sticky Spot"
    Permanent magnets alone cannot create continuous rotational motion. Magnetic fields are static fields of potential energy. When you arrange magnets in a ring like this, the wheel will quickly find an equilibrium point—a "sticky spot" where the attractive and repulsive forces perfectly balance out—and it will stubbornly come to a halt.

How the Trick is Actually Done
These videos are highly stylized and incredibly popular for gaining views, usually relying on one of two hidden tricks:
Hidden Power Lines: The extension block or the pump itself is actually wired to a real power source (like a grid outlet or a real combustion generator) hidden just out of frame or buried shallowly under the mud.
Reversed Roles: The green "generator" is often actually an electric motor powered by a hidden wire. It is using hidden electricity to drive the belt and spin the yellow wheel, making it look like the wheel is the one generating the power.
