Hitachi Engineers confirm Over-Unity Process
Application by Kawai of adroit self-switching of the magnetic path in magnetic motors results in approximately doubling the COP.  Modification of an ordinary magnetic engine of COP < 0.5 will not produce COP > 1.0.  However, modification of available high efficiency (COP = 0.6 to 0. engines to use the Kawai process does result in engines exhibiting COP = 1.2 to 1.6.  Two Kawai-modified Hitachi engines were rigorously tested by Hitachi engineers and produced COP = 1.4 and COP = 1.6 respectively.  The Kawai process and several other Japanese overunity systems have been blocked from further development and marketing.

The Kawai process can be built directly from the Patent, using high-speed switching (such as very efficient photon-coupled switching).
