  • Patent number: 7330094
    Abstract: An energy producing apparatus utilizing magnetic pistons is provided. Permanent magnets of like polarity are employed within a cylinder of each piston and upon a top portion of said piston. The like polarity pistons have a natural desire to repel one another. A ferromagnetic slipper unit is inserted into a gap in said cylinder between the permanent magnets of like polarity to interfere with said magnetic repulsive field and to cause a magnetic attractive field. Each piston is attached to a push rod which in turn is attached to shaft and flywheel system. The change in magnetic fields from repulsion to attraction cases the piston to push up and down and turn the shaft and flywheel system. Two pistons in coincidence can be used so that while one piston is repelling, the other is attracting causing an increase in motive power.
