In reply to Peter Gluck's message of Tue, 19 Apr 2011 17:41:27 +0300: Hi, [snip] >I think the most important conclusion of this discussion- is that heat >transfer is the main obstacle in scale up of this type of heat generators. >The surface/volume ratio diminishes with increasing the dimensions. [snip] This is only true while the ratio of radius to length remains constant. One can easily increase the total thermal conductivity as far as desired by simply increasing the length at constant radius. Hence heat transfer should not be a restriction on scale up. In fact if the Nickel powder is indeed bonded to the inner surface of the stainless steel (which I think was a brilliant suggestion BTW), then the inner chamber could easily be extended to form a Hydrogen carrying tube. The whole could then be made to any desired length (and potentially coiled up inside a boiler).
