I think the Rossi device <http://pesn.com/2011/04/07/9501805_Rossi_Cold_Fusion_Validated_by_Swedish_S keptics_Society/> may be the real deal but there is a growing consensus that no one is really sure how it works. Rossi is
presently denied a patent in Italy because his theory isn't based on current physics and is unable to "teach" the method to another suitably educated person reading the patent. My advice to Rossi would be to re-package the patent in the closest form to the PTO requirements based on presently accepted physics. [without mention of ZPE] 1. that the energy is derived from the random motion of gas atoms attributed to HUP by a new method that escapes the assumption that gas motion is too small and chaotic to be rectified - exploited. [using nature and geometry where we only have to supply heat] 2. That gas motion through rapid changes in very active catalytic geometry can exploit catalytic disassociation of heated gases near their threshold temperature. 3. This method without a cooling loop already reflects many of the anomalous heat claims by Mill's Arata and Moller which quickly runs away and stops the reaction by overheating and melting down or reacting with the catalyst to produce hydrides. 4. To make the one time runaway reaction into a closed loop steady state reaction, the cooling loop and initial heating PWM must be brought up slowly together in balance such that the brief current pulse to the heater only puts the reaction barely into runaway but then gets quickly pulled out of run away by the removal of the pulse and the steady thermal drain of the cooling loop. The duty factor and PRF being critical to match the heat extraction ability of the cooling loop. 5. The point being that many more of the molecular gases near threshold are disassociated during this brief runaway then the energy in the pulse can account for and when repeated at a cyclical rate, we are effectively rectifying the chaotic motion of those molecules which were pushed into a different catalytic zone to disassociate additional molecules. Both the molecules disassociated due to motion and those due to the current pulse to the heater contribute energy as they reform back into molecules during the off time of the pulsed waveform. 6. This excess energy in the lattice increases the probability of nuclear reactions which is evidenced in the Cu and Fe ash of spent fuel in the Rossi device. I'm sure someone more qualified can expand on the nuclear paths but I think this explains where the energy to make these reactions favorable is born. Regards Fran
