An expert in rocket plume heat measurement has apparently approved one of the 3 most controversial aspects of the Rossi "HotCat" evaluation recently published <http://www.sifferkoll.se/sifferkoll/wp-content/uploads/2014/10/LuganoReportSubmit.pdf>. The temperature output was at peak 1400C. While this temperature is not going to achieve the Isp's of even chemical, let alone nuclear, rockets, it is significant that the specific energy of the purported fuel is far above conventional chemical sources. If these systems really do require only conventionally available materials, it is plausible that this could evolve into a rocket technology, accessible to amateurs, with near nuclear performance. ---------- Forwarded message ---------- From: Jed Rothwell <jedrothwell@xxxxxxxxx> Date: Mon, Oct 13, 2014 at 1:26 PM Subject: [Vo]:An expert reviewed and approves of this configuration To: "vortex-l@xxxxxxxxxx" <vortex-l@xxxxxxxxxx> Brian Ahern just called me to say that he spoke with expert in thermal imaging. The expert went over the paper and said this was exactly the right kind of camera for these materials and this range of temperatures. The guy said surface roughness and various other factors come into play. He knows something about alumina and he said these are the instruments and wavelengths he would select. Brian said his own doubts have been resolved. Normally I would have jotted down more details, such as the expert's name, but I didn't because Brian promised to send me a note with the particulars. It occurs to me he is not a good correspondent. He is a busy bee . . . If he does not send me the info. I'll call him back and get it. This expert does things like measure the temperature of rocket plumes. I told Brian I have heard of people using IR cameras for volcanoes. They are good for uncontrolled, high-temperature phenomena. Details to follow. Brian is a good egg. - Jed
