Pete, you're welcome. I'm using this same heating element in my disposable reactor. I'm attempting replication of Rossi, not Phen\Chan which I think may be a red herring. Something just does not smell right to me about Chan\Phen's method. I suspect Chan\Phen may have ignited the propane in his tube and initiated a low-grade chemical burning of his mineral oil bath. Using Mineral Oil as coolant and propane as "Inert gas" just does not seem right to me.
Anyways, I calculated that I load the reactor at 30C (room temp) or around 300K and at 300-360 psi (Rossi's initial H pressure). Heating the reactor to 700K (423C - Focardi's "Ideal" temp) would bring the H pressure to around 700 psi according to the Ideal Gas Law formula. I don't think 700 psi is that difficult to handle in a reactor. My initial attempt will be to use a copper tube rated to 2240 psi @ 72F. Derating charts I found said to derate the psi rating when temp increases. So I suspect, my copper tube should handle 700psi @ 423C. If not, I'll upgrade to a stainless steel tube, which will do 2000psi @350F. These are "official" safety ratings, so the actual burst rating would be about 3-5 times higher. I intend to place the reactor in a blast chamber (8" concrete walls) and monitor using Wireless IP camera. At 700 psi reactor target pressure, this heating element should work. BTW, did you notice that the same seller lists other similar heating element of various sizes? Go to his store, he has other sizes.

Thankyou for helping , it might just do the trick I have a young electrical engineer helping me out once a week , he is concerned the element it self may not handle the pressures building up in the chamber In our intended experiments we are going to do 2 main types 1. Phen\Chan way 2. Rossi way Phen doesnt heat the chamber while the H is at 2000psi But Rossi seems to do this The engineer seems to think by heating the chamber to 400 C increases the PSI x 3 (approx) Which means the pressures would be around 6000 psi He questions if most elements could handle this type of pressures Question : Do you think Rossi heats the chamber while the H is pressuised at 2000 psi Thanks Pete ------------------------------------------------------------------------------ From: jth...@hotmail.com To: vortex-l@eskimo.com Subject: RE: [Vo]:DGT Screenshot Date: Wed, 1 Feb 2012 16:27:03 +0800 Peter, How about this cheap heating element. Fits inside a 1/4" copper tube perfectly. http://www.ebay.com/itm/350505999493?ru=http%3A%2F%2Fwww.ebay.com%3A80%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dm570.l1313%26_nkw%3D350505999493%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1 Jojo
