@gameover,
I recall the SiC heater graphs having a negative R curve that flattened out at a high temperature. Perhaps that is engineered with grain sizes and geometry?
I have no idea about the rest of the materials. but I would think there would be some sort of limit. (Maybe there isn't)
Something to consider when experimenting with this stuff.
There are some neat videos (several were posted on the forum a year ago maybe) of glass being turned into a melting-glowing conductor with 120 V.
Rossi's patent says that the heater only gets the reactor up to operating temperature. Then the glow discharge takes over operating between 50 and 100 KV. There is a concentration on non Rossi compatible and non applicable experimental process here.
@axil,
Rossi says a lot of things, not all of which are correct.
Rossi would not lie in his patent, would he?
@axil,
The patent application in question might contain things he feels are important, but are actually not important. His theory could be incorrect. There are many errors in some applications, which get corrected over time, and sometimes not.
If the patent/application theory is wrong, and you base your theory on it, then it is most likely that your theory will in turn be wrong, or lead to wrong conclusions.

Please read this update. It will save much nonapplicable debate about reactor processes that is based on the Rossi patent.
In this context it is perhaps worth mentioning that the fission reaktors should in the present build as durable reaktors to be suitable for conversion to LENR reactors.
I'm not sure how practical a dual-purpose reactor would be. Once you have fired it up for a while the inside is contaminated beyond - so the simpler thing to do would be to build another heat source (LENR would be nice) alongside it. Then at least you can use the same turbines and grid connection. But it may be that LENR would lend itself to a new kind of distribution mechanism- locally generated power for local needs- in which case there would be no need for a big central power station.

When the NRC and IAEA become aware that the Rossi reactor design produces Li6 (a bomb capable material) from Li7, they will only allow LENR to be used as other bomb capable materials are now used, in big utility based nuclear reactors.
I have posted the applicable laws; do you choose to ignore those laws?

I do. When something is as useful and important as this could be, may the devil take the hindmost. 'Tis the future of our biosphere after all.

An object lesson from history
http://www.argee.net/DefenseWatch/Nuclear Waste and Breeder Reactors.htm
QuotePlutonium is used in atomic bombs - the fact that it's pure Plutonium-239 that makes an atomic bomb work, and not the other three isotopes, apparently didn't matter, because in 1977 President Jimmy Carter signed an executive order that banned the reprocessing of nuclear fuel in the United States. The rationale was that the Plutonium could possibly be stolen, and terrorists or rogue nation states might be able to use it to make atomic bombs.
The Lithium 6 situation
QuoteLithium 6, the ash that Rossi's reactors produce can also be used in nuclear bombs and access to it is restricted by the NRC and the IAEA.
QuoteDisplay MoreTritium production
A third important nuclear reaction is the one that creates tritium, essential to the type of fusion used in weapons. Tritium, or hydrogen-3, is made by bombarding lithium-6 (6Li) with a neutron (n). This neutron bombardment will cause the lithium-6 nucleus to fission, producing helium-4 (4He) plus tritium (3T) and energy.
A nuclear reactor is necessary to provide the neutrons if the tritium is to be provided before the weapon is used. The industrial-scale conversion of lithium-6 to tritium is very similar to the conversion of uranium-238 into plutonium-239. In both cases the feed material is placed inside a nuclear reactor and removed for processing after a period of time.
Alternatively, neutrons from earlier stage fusion reactions can be used to fission lithium-6 (in the form of lithium deuteride for example) and form tritium during detonation. This approach reduces the amount of tritium-based fuel in a weapon.
It is a long standing policy that the production of all materials used in the construction of nuclear bombs shall be controlled by nuclear regulations.
I have advised that because of this long standing policy, Rossi's technology will be controlled by the NRC and the IAEA if it is permitted to exist at all.

MANAGEMENT
NNSA Should Ensure
Equal Consideration
of Alternatives for
Lithium Production
QuoteDisplay MoreNNSA is responsible for the management of the nation’s nuclear weapons, nuclear nonproliferation, and naval reactor programs. NNSA relies on contractors to carry out these responsibilities and manage day to-day operations at each of its eight sites. These sites include laboratories, production plants, and a test site. Together, these sites implement NNSA’s Stockpile Stewardship program that, among other things, includes operations associated with maintenance, refurbishment, and dismantlement of the nuclear weapons stockpile. As discussed previously, lithium is a key component of nuclear weapons and is therefore essential for the refurbishment of the nuclear weapons stockpile. The following NNSA sites are involved in processes or decisions that impact the supply of lithium:
• The NNSA Production Office is responsible for overseeing contractor performance at the Pantex Plant and Y-12 National Security Complex, including the majority of the physical work on weapon refurbishment.
• The Pantex Plant located near Amarillo, Texas, dismantles retired nuclear weapons.
• The Y-12 Nuclear Security Complex disassembles canned subassemblies (CSA) from dismantled weapons; these CSAs contain lithium components that are the source material for lithium production for refurbished weapons.13 NNSA’s Y-12 site is also responsible for lithium production, which involves recovering lithium-6 from disassembled weapons, cleaning it, and preparing the cleaned lithium into forms suitable for refurbished weapons.
• NNSA’s Los Alamos and Lawrence Livermore National Laboratories qualify, or approve, the lithium produced at Y-12 to ensure that it is suitable for use in refurbished weapons. NNSA program offices are responsible for overseeing and supporting the activities performed by its contractors. NNSA’s Office of Stockpile Management, within its Office of Defense Programs, oversees the maintenance, refurbishment, and dismantlement of nuclear weapons—to include overseeing Y-12’s plans for meeting lithium demand.
Th 'UNofficial' position is a little less fraught than you imagine. Discussing the 'tritium problem' with one of the SRI researchers he told me that since they had an experiment that was producing tritium they applied for a tritium license. The response was 'you can't possibly be making tritium, so you don't need a license.
So the world turns.
ETA. Sigma Aldritch offer quite a few Li6 items, including metal chunks at 95% purity in 10gram packs, though they have discontinued Li6Deuteride. Perhaps nobody told them it is forbidden?
Perhaps nobody told them it is forbidden?
This is what I am telling all who will listen, that the production of Lithium 6 through transmutation is forbidden.
IH has made a bad deal with Rossi, but I am telling IH now that the Rossi tech is forbidden by law. IH should pursue a LENR technology that does not produce lithium 6 as an ash.
Those who will not listen can disregard this advice but an opponent of LENR can use the lithium 6 restriction as a lever to destroy the IH/Rossi technology.
Possibly only in America. The rest of the world doesn't believe in transmutation anyway. You are banging a drum that nobody cares about.
BTW- nobody told 'American Elements', either. They have immediate availability.

'American Elements' also sells thorium which I know requires a licence to use. 'American Elements' must be a licensed producer of lithium 6. All restricted nuclear materials require a licence issued by the NRC to buy and use. Any seller of restricted nuclear materials must be licenced. Therefore, any Rossi type of LENR reactor must also be licenced by the NRC.
Regarding: "The rest of the world doesn't believe in transmutation anyway."
There will come a time when the the rest of the world will believe in transmutation, and that transmutation will be controlled by the government worldwide.
Alan, This is a great idea, the additional costs allowing layout changes would be almost zero.
Looking thru a trade magazine and saw a new product ad by Aremco for Ceramacast 586.
High dielectric 125V/mil, high resistivity 10^9 ohm-cm, good to 2,800F...
Thought it may be of interest here.
Have you got a link? Though 2800F is 1537C - about the same temperature as our current Alumina tubes are good for. But it may have other good features.
