I was wondering how long it would take for Mr. Rothwell to come up with some practical statistics on the Rossi heat-transfer matter. Not long at all! ;-) I suspect the recent heat transfer disagreement, as expressed between Rothwell and Beene, is of great interest to many Vort participants. As I understand it, there appears to have been legitimate concerns raised as to whether there exists sufficient SURFACE AREA within Rossi's e-Cat reactor in which to allow a sufficient amount of heat to transfer from the core of the reactor to the adjacent water flowing nearby. Heat transference is indeed a tricky issue. The more volume there is to contend with the more problematic it becomes in transferring (or expelling) internal heat. In fact an object in the shape of a perfect sphere would be the worst case scenario for expelling excess heat. That is why one tends to see, for example, rows and rows of metallic flanges acting as heat sinks attached to motorcycle engines. That is done in order to increase the surface area in which to dump/expel excess heat. If Rossi's e-cat reactors contain lots of tiny metal flanges, acting as heat sinks that would help in the heat transfer as well. Personally, I suspect, Rossi is probably not employing such internal designs with his current e-cat design. It would, however, be a good suggestion to consider for future designs - if excess heat becomes an issue. It would seem to me that Mr. Rothwell has revealed reasonably convincing statistics to suggest that there probably exist sufficient "surface area". However, that remains to be verified since I gather the guts of the Rossi device are still proprietary. In the meantime, I suspect Mr. Beene will probably not find Mr. Rothwell's analysis convincing, and I fully expect a counter response.
