Last year - 2014 - the neutrino mass was accurately measured for the first time. To cut to the chase, the average mass-energy of neutrinos (all of the 3/6 varieties) is about .32 eV, which is the thermal equivalent of about 2900 degrees C. This is an accessible value which has practical implications if thermal resonance can be made into an operating parameter.
Since the early days of LENR, a few theorists were predicting that neutrinos could provide some of the answers to the excess heat, since the neutrino flux is extremely large. At that time, it was not yet proved that neutrinos had rest mass, however. But it is obvious that capturing an extra micro % of the total flux would provide the easy route to thermal gain, with no gammas. To confuse things however, neutrino capture would also create a few nuclear reactions, in addition to direct heating. Since any slight increase in the capture rate of the neutrino flux would make a huge difference in thermal properties of the target, this could be a fertile area of research, (now that an actual value can be attached to neutrino mass-energy). In the simplest case, we need only ask: can neutrino capture be enhanced by even a tiny amount simply by providing a better "antenna". such as a heated antenna? . cough, cough. such as a "dogbone antenna" :-) If so, then we should see anomalous thermal results in other industrial areas where metals are routinely melted (metal casting and forging). And indeed, one thermal phenomenon that comes to mind here is known as "recalescence." The extra heat of recalescence is usually attributed to phase-change, but this has not been well-studied. https://en.wikipedia.org/wiki/Recalescence Neutrinos interact weakly with cold matter and are hard to study and measure but with a heated antenna, which could be kept at say - one-half the equivalent rest-mass temperature of the neutrino flux, then the possibility arises of creating a thermal resonance around the blackbody value of the IR radiation level, in order to enhance the capture rate slightly. The input heat need only provide a trigger for positive reinforcement but it would seem that a small magnetic field is also useful. Just a thought for Bastille Day, Independence Day, Canada Day and the other July National Days. Maybe in a few years we will be celebrating "Energy-Independence Day". well, that sounds preferable to Neutrino Day :-)
