Not Awarded

Note by Mark Goldes of Directory:Magnetic Power Inc, May 22, 2006

Patents are issued by individual countries. The PCT is a way of applying to several countries at once.

All such patents are published 18 months following filing.

This is merely the publication of his application.

There is no approval implied.

The documents at the end indicate his application has been challenged as being a perpetual motion machine, which no patent office in the world will patent.

The name of his firm does not help his case in this regard.

I wish him every success. The world needs this technology urgently.


The invention provides a magnetic repellant motor which comprises: a shaft (26) rotatable about its longitudinal axis, a first set (16) of magnetics (14) arranged about the shaft (26) in a rotor (10) for rotation with the shaft (26), and a second set (42) of magnets (40) arranged in a stator (32) surrounding the rotor (10), wherein the second set (42) of magnetics (40) is in interaction with the first set (16) of magnetics (14), wherein the magnetics (14,40) of the first and second sets (16,42) of magnetics are at least partially magnetically screened so as to concentrate their magnetic field strength in the direction of the gap between rotor (10) and stator (32).
