Unfortunately, Zhang et al. tell me they have not yet written a paper, but here is the Abstract: 9:36AM A31.9 Heat Produced During Electrolysis with a Tubular Pd Cathode, WU-SHOU ZHANG, JOHN DASH, QIONGSHU WANG, Low Energy Nuclear Laboratory, Portland State University, Portland, OR 97207-0751 An explosion occurred during electrolysis of heavy water with a tubular Pd cathode1 A Pd tube from the same batch was used as the cathode during electrolysis in a Seebeck envelope calorimeter which is capable of accurate heat measurements. Data was obtained first from a three cm length of the tube on one end, and then from a three cm length on the opposite end. There were no explosions, but both ends of the tube produced continuous excess thermal power (356 mW +/- 11 mW maximum). In addition there were 39 heat bursts (1.1 W maximum) from the first end during 201 hours of electrolysis and 58 heat bursts (1 W maximum) during 443 hours of electrolysis from the opposite end of the tube. The period of the heat bursts ranged from a few minutes to 3.3 hours. Data on the topography and microchemical composition of the tube surface before and after electrolysis will also be presented. - Jed Jed, it is like nobody saw or read this! Is'nt anybody going to answer this post? The guy is claiming a watt from three centimeters of wire for cryin our loud. If true this is really good news. Instead folks are seemingly more interested in some 'scam'. The word 'reproducibility' has cropped up here as well, and that makes it more interesting. If Gene were around, he surely would be interested. Standing Bear

Well, it is not unexpected. This is cold fusion, after all -- that's what it does. Fleischmann and Pons used to get upwards of 100 watts from a few centimeters of wire. Zhang and Dash have been very cooperative in the past so I expect they will send me a paper as soon as they write it. I will upload it and post a message here. That's what I do. I just now uploaded a new set of PowerPoint slides that describe a new paper: Hubler, G.K., Anomalous Effects in Hydrogen-Charged Palladium - A review (PowerPoint slides). Surf. Coatings Technol., 2007. http://lenr-canr.org/acrobat/HublerGKanomalousea.pdf - Jed

The explosions are described here: http://lenr-canr.org/acrobat/ZhangXontheexplo.pdf The Seebeck calorimeter was made by Heinz Poppendiek, of Thermonetics Corp. It is the blue box shown in the photo here: http://lenr-canr.org/Experiments.htm#HighSchoolStudents (8 photos down) I think Ed Storms might quibble with error estimate of +/- 11 mW, but it is very precise, and you can use it to measure 356 mW or 1.1 W with confidence. - Jed
