Let's not forget that momentum has TWO components: mass and velocity. Energy and mass are interchangeable, mass is not (necessarily) constant. For example, 1% of nucleon mass typically disappears into binding energy, a.k.a. mass deficit. When we constrain position or spin or any other quantum state, we have a particle that is much less certain of both its mass and its velocity. If the particle's speed is a significant fraction of the speed of light, there's only one way to increase uncertainty in momentum: mass. -
So does the chemical industry split H2 to 2H? I find this section of the Wikipedia article on the Haber Process (for ammonia production) interesting: https://en.wikipedia.org/wiki/Haber_process#Catalysts
"The most popular catalysts are based on iron promoted with K2O, CaO, SiO2, and Al2O3. The original Haber–Bosch reaction chambers used osmium as the catalyst, but it was available in extremely small quantities. Haber noted uranium was almost as effective and easier to obtain than osmium. Under Bosch's direction in 1909, the BASF researcher Alwin Mittasch discovered a much less expensive iron-based catalyst, which is still used today. Some ammonia production utilizes ruthenium-based catalysts (the KAAP process). Ruthenium forms more active catalysts that allows milder operating pressures. Such catalysts are prepared by decomposition of triruthenium dodecacarbonyl on graphite."

I am absolutely addicted to the drama. In the last few days, @me356 raised his head to say "Remember me? I have been busy for the last few months. And now I can light up me356Cats at will". And seems quite happy to discuss all aspects of lighting one up except one: the secret trigger that ignites the reaction. Is that the same secret that Rossi failed to divulge to IH?
Pass the popcorn, please.
If LENR does exist, that's great and we can fit a few billion more souls on our planet (and probably use it to terraform Mars and Venus while we are at it.) It's just too bad that everybody on low lying islands will suffer the consequences until the IP drama plays itself out.

but also the residual gas should have also a mass spectrometry. 1H, D, T, 3He, 4He
Is that even feasible? At 10-1000 Pa in a small reactor, there just isn't much of it to analyze.

The steel layers can be charged with DC voltage to set up a uniform electrical field. This could cause susceptible bits to align to the field. It could capture charged particles avoiding safety issues. It could be a way to generate an electric current as output.

Binding arbitration: arrangement where two parties agree to present their arguments and evidence to a neutral third party and to be bound by the arbitrator's decision. Frequently the arbitrator is required to rule for one side or the other, although compromise settlements may sometimes be negotiated.
It seems the ERV is stipulated in their contract as having sole authority to determine whether performance criteria were met.
I wouldn't want to be IH's attorney pleading a case before a judge of "We agreed to conditions and we agreed upon an umpire, but we now need to change both."

Inexpensive vacuum pump good to 10 Pa.

5. ?
Static magnetic field?
Static electric field (charged plates)
RF stimulation of magnetic resonance?
IR (terahertz) stimulation?
Modified waveform in heater coil?
Europe = 50 Hz, US = 60 Hz.?
Sonic stimulation?
Mechanical stimulation?
Stray muons or neutrinos?
Trace semi-stable "ignitors"? C14, Potassium, ... -

is there an efficient way to crevert RF back to electrical energy?

@Hank Mills
I believe this table gives exactly what you are looking for: values are the temperature needed to achieve the given vapor pressure (across the top of the table ... 100K Pa is 1 atmosphere) -
me356. PLEASE consider a simple calorimeter to definitively measure excess heat.
Configure the reactor to boil water, preferably water that is distilled or demineralized by reverse osmosis. A simple kettle will suffice, but insulating the system so all heat loss is through evaporation would be better.
With the system heated to boiling, record the water level. Run the device for 30 minutes with excess power off mode, measure the amount of evaporation.
Repeat. Same starting conditions (refill the water and bring it to boiling), but run in excess power on mode. Everything else the same: power input, 30 minute duration, and same water level measurements. Excess heat should cause more water to evaporate.
The difference in water evaporation between the two runs will give us a lower boundary for excess power with no room for bickering about thermocouple stability, IR camera calibration, or other secondary minutiae.
That heat is enthalpy of vaporization of water is 40.65 kJ/mol.
A mole of water weighs 18 grams.
1 gram of water = 1 cc.Excess heat in kJ = excess water evaporated (in cc) * 1 (gram / cc) * 1/18 (mole / gram) * 40.65 (kJ / mol)
If you prefer kWh: 1kJ = 2.7778*10^-4 Kilowatt hr -
Bob Greenyer will be doing the TV infomercials! RIP Billie Mays. Move over "Sham Wow Guy" Vince Offer. There's a new king of 3 am television.

@'Walker
Wow, Rossi must wear extremely large glasses!1 MW x 24 hrs/day = 24 MWh each day.
24 MWh = 656 gallons of gasoline
Using 40% fuel-to-steam conversion efficiency, he needs about 1640 gallons of fuel a day. (Reduce that by 10% for a reported COP of 10.) -
@Thomas Clarke
I am recalling Dr. Parkhomov's initial runs in which he devised a simple calorimeter by measuring the amount of water that had boiled off. His tests were limited, in part, by his ability to replenish water at odd hours. Let's hope there isn't a whole lot of difference between that simple measurement and input / output data collected for Mr. Rossi's test. It would be best if power input, water input, steam output, and conductive / convective losses all add up. I suppose the downside is that sort of bulk flow calorimetry cannot reveal short bursts of thermal activity, since it inherently averages things out over time. However that sort of simple metric would be ideal for corroborating evidence during a long-term test. -

Thank you, joshua cude. But I still don't have a definition of "low energy". I withdraw mine, it sucks. Please tell us where the line is for "low" so we armchair critics and theorists can better cast judgement on the people who are actually doing all the work. As a follow on, please define "cold" so when somebody gets a reactor running in my garage, I know whether it is "cold" fusion.

@Thomas Clarke
What is demarkation line between Low and High energy? 100kEv is above your line, but not mine. To me, the Low in LENR means "at a minor fraction of the level found in the core of stars."
