Quantum interference with microspheres. http://arxiv.org/abs/1603.01553
"Really cold cold-fusion" is not exactly new. This paper made me wonder about the dividing line between quantum and classical, which is generally somewhere in "nano-land" or just beyond. Quantum dots are generally the upper limit, and they can up to around 150,000 atoms within the quantum dot volume, which is a diameter of ~ 50 atoms. This corresponds to the Casimir geometry of less than 20 nm. Everything large was once considered "macro". It is considered big news when Quantum properties are seen to move up to macro dimensions; and a "microsphere" is considered relatively large, in terms of QM. At least it is much larger than a quantum dot. Typically the microsphere range is a million times more massive than a large molecule and 10,000 times above quantum-dot geometry. This is the low end of the range of nickel particles used in LENR. But this is a range where the material can be obtained commercially without cadmium content. There are sellers of so-called quantum dots but they are using a very loose definition. Quantum interference is a challenging principle of quantum theory - but it can partially explain some features of LENR, including the difficulty to achieve "on demand" operation, the need to control operating parameters within a narrow 'sweet spot' and the advantage of a magnetic field. We would not expect to see Quantum interference properties show up in a particle of one micron or above. Essentially, the Quantum interference concept proposes that waves-particles - can be in more than one place at the same time (through superposition) and that an individual wave-particle can interact with itself. It is hard to imagine this happening with macro-sized particles, even at cryogenic temps. This paper seems to indicate that - at least when cooled sufficiently, micro-sized particles could operate as quantum dots. This is possibly not terribly surprising, but it does raise the possibility - once again - that the best way to implement LENR could end up being in a non-thermal role. Using cryogenics and media for experimentation which can be bought commercially, we would also probably need to see superconductivity as a property of the gainful material. Turns out. and it may be no accident . that palladium deuteride is superconductive. Of course, if we are to utilize or even conceptualize a derivative concept of "really cold cold-fusion" then we must find a way to convert gain directly into electricity, or at least into photons which are non-interacting (translucent matrix) while maintaining the cryogenic state. Real fusion seems to be incompatible with cryogenics, but that applies to those who are thinking with the proverbial box. Direct conversion of gainful energy using cryogenic reactants - "really cold cold-fusion" may not be as difficult to achieve, as it seems at first glance. There is not new. It has been considered before, but the new twist is the realization that the particle size must be reduced. but probably not all the way to the quantum dot level.
