-----Original Message----- From: Roarty, Francis X > the concept of milling/high speed mixing a colloid of nano suspended catalyst would certainly seem to trump the Griggs idea using just water.
A few points worth mentioning wrt Griggs. >From the evidence and tests which were run at the time, and Jed may have more to say about this, many careful observers were open to the conclusion that Griggs may have seen OU at time, but unreliably. His active cavitation elements was a large rotor with milled indentations. These were not small. Nanotechnology was in its infancy and never mentioned AFAIK. It is consistent with all we know to suggest that during the time spans that the Griggs pump worked reliably for excess heat - these coincided to self-created nano-pitting in the metal stator, and/or colloidal particles in the water. There are a number of instances of iron oxide colloid in water (brown NOT red) being associated with water energy anomalies. Jones
