Fran, Your point even better. Use round fins ~2 mm apart brazed to the center heat transfer fluid tube. Center tube brazed to bottom cap which has a hole for center tube, this brazed as well. Would use copper tubing for all these tubes and fins, standard plumbing parts. Fill from upper side with powder, vibrate to fill all the gaps between fins, then braze the upper cap onto the outer tube, and braze the center tube to the hole in the upper cap. That would be a sealed reactor, ready to plumb into the cooling fluid pathway. H2 inlet to the outer tube. They could slide a lead pipe over the outer tube if needed for gamma.
Gas heat the heat transfer fluid and temps would rise slowly thoughout, when it starts reacting, turn off gas heat, and increase fluid flow to maintain safe efficient temps. Also, think Jones had it quoting that study on the highese H bonding with the, was it 70/30 Ni/Cu alloy powders? I think we need more discussion on the Fe from rust role. ----- Original Message ----- From: francis To: uniqueprodu...@comcast.net Cc: vortex-l@eskimo.com Sent: Sunday, June 19, 2011 1:23 AM Subject: Re: [Vo]:New private E-Cat test with no input energy Jay, Excellent idea - could even use off the shelf heat exchanger as your link seems to indicate they already have their brazed products in automotive and aerospace equipment. I like the idea of the heat transfer fluid being inside the exchanger with the sputtered powder on the outside and using a large hydrogen supply tube around the entire exchanger which would function as the reactor. I think this would greatly increase the surface area and number of ultra active sites. I noticed you are still sugggesting filling the reactor tube with powder around the heat sink in addition to the coated surface of the heat sink. My original thought was to do away with bulk powder entirely but after reconsideration think you may also have gotten that right, Previous discussions about there being a certain critical volume of powder and spill over catalysts may mean the thin surface does have to be part of a larger volume for OOP and free running operation. Maybe the MAHG device should have been filled with powder as well?FranOn Sat, 18 Jun 2011 21:04: Jay Caplan wroteFran,If you could sputter the powder surface onto the fins of a brazed heat exchanger http://fintube.thomasnet.com/item/all-categories/finbraze--2/item-1010?&forward=1 then the H2 could be inputted through a tube surrounding the finned exchanger (with an outer lead pipe shield if there actually is gamma to deal with.) The heat transfer fluid running through the center tube - center tube welded to the outer tube at the ends to maintain H2 pressure. Brazed fins for continuous duty to 950 F. But it might be easier to have square fins with ~1-2 mm between them, and the adjacent two fins brazed closed on 3 sides. http://fintube.thomasnet.com/item/all-categories/stamped-plate-fin/item-1015?&forward=1 Fill the top side with the nanopowders, vibrate to settle, H2 still loads from the outer tube. ???
