Thanks Brad, Andre, Jojo. I dont know how many here have concrete intentions to build a LENR- device themselves. Let me say a couple of words -as simple as possible- about a device based on Ni-H:
1st) Nano-Nickel seems to be essential, and there seems to be some optimal particle size- 10-100nm. I tend to the lower sizes 2) The particles have to be handled such that they are not oxidized 3) the reaction itself takes place, when H, or some variant diffuses into the lattice in sufficient amount 4) A startup-temperature is needed, in the range of 300 to 500 deg C 5) an additional excitation is needed, maybe a spark (I doubt that) or other forms of excitation (RF), or a catalyst (I doubt that) 6) the excess heat has to be harvested in such a manner, that no Ni-melting occurs. On the other hand the reactive volume is so small, that it is quite difficult to remove the excess heat from a small volume, say a couple of cm3.Think of a processor, who produces some 100-200W on a surface of several cm2. 7) one should separate proof of concept from an optimized device with COP >>6 and such. 8) energy-production and harvesting should be as evenly distributed as possible in the active volume. Which is hard, even in a proof-of-concept device. I conclude from that, that something like a spark finds its way of lowest resistance, and produces so much heat, that particles bake together, and stop the reaction. Think of a lightning. In addition to that, the spark is a positive-feedback and would further on enhance this path, stopping the reaction in short time. This is important to recognize. Contrast this with controlled RF -whatever optimal frequency- where a volume is involved, and not a path. On the other hand: there seems to be no reliable indication that anybody used RF or sparks in addition to heat. This is an open question. Comments welcome. So my basic first idea would be implementing a) effective influx of H2 in a Nano-Powder Ni-chamber b) constructing it such, that the VOLUME can be effectively heated for startup. c) that any excess heat can effectively be removed from a small volume (very difficult!) d) that some some additional excitation can be applied (RF: maybe; sparks: doubtful; catalysts, doubtful) This as a starter. ________________________________ Von: ecat builder <ecatbuil...@gmail.com> An: vortex-l@eskimo.com Gesendet: 19:21 Montag, 12.März 2012 Betreff: Re: [Vo]:To Spark or Not to Spark I agree that more people should be working on some type of crowd-sourced building.... - Brad
