Why is it so difficult to make such a simple test properly if we are talking about a earth shattering discovery and with budget of 500k$? Kids in high-schools are doing tests on this levels with 100$ budget.

Because when you improve the instrumentation, the effect goes away. :)

Imagine you plug in a flowmeter during the run. The data says there was no fusion occurring. "Huh", you might say, "The flowmeter did something that interfered with the device." So you remove the flowmeter and, voila, your data again seems to tell you that the device works.

I remember that Tom Bearden's "motionless electromagnetic generator" could only actually generate heat in a special "prepared resistor"---i.e., one which had previously been lightly fried by a high current. So if you were to ask Bearden to run his MEG into a nice, calibrated power meter, or a reference resistor, or a calorimeter---no, that would disturb the free-energy. It only worked with this one resistor.
 
Yevgen - As my previous posts have made clear, I'm morally certain that Rossi is a fake, so please don't take the following as essential disagreement, only one of details.

In the Swedish Report, a graph was shown of the outlet water temperature, which shows a jump in water temperature when it reaches 60 C. My physical intuition says your explanation doesn't work, since I don't see how boiling could occur with that low an outlet temperature. And the temperature rise prior to the jump was so slow that I don't believe there was a significant time delay between the heater and the measurement which would serve.

Yes, this is correct. I did not add it to my this particular comment, but
as I described earlier, the heavy bulky lead shielding looks very suspicious considering that no radiation was ever detected. It looks like an excuse to hide batteries or other energy source. Such energy source can be used to give a bust at around 60C.
In fact Ni-MH batteries that are widely available in any store have exactly
this convenient behaviour - they have self-discharge that accelerate with
temperature and become significant at 60C. This self-discharge will release additional heat and increase temperature further (and in fact can cause to thermal run-away and explosion at about 110C).
What I found hilarious that a few days after I posted my comment about 110C limit in this forum, Rossi wrote in his blog / journal that "maximal temperature in E-cat is 110C). If that is a coincidence, its probability is rather close to probability of exceeding electrostatic fusion barrier at 110C :-)

Yevgen

Actually, the lead shielding is specified as 2 cm thick. Most of what you see is insulation. And, as I've mentioned before, this severely limits the putative radiation energy levels to something like 100 KeV or less, which is nothing like what Rossi claims in his patent application.
 
Absolute agreement on his lack of an enabling disclosure. My point is, if you read it, he doesn't try to hide the fact that he's discussing cold fusion. I've seen some applicants who bend over backwards to avoid saying anything of the sort, and go out of their way to use obfuscating terminology to conceal what it is they really think they're doing.




Following up on this, I've just run across a really good example of an issued patent, where we can ask the question: Is it cold fusion, or not?



US Patent 7 556 783 Hydrogen isotope fuel cell


Abstract:

An energy conversion cell for converting electric power into heat. The cell includes a non-conductive housing formed of spaced, preferably glass outer plates sealed along common perimeters thereof to define a closed interior volume or chamber. At least two catalytic plates are held spaced apart in the interior volume, preferably separated by a dielectric plate. The catalytic plates are preferably formed of very thin palladium plate material. A gas passage in gas communication with the interior volume is connectable to a source of pressurized hydrogen (H.sub.2) or deuterium (D.sub.2) gas deliverable into said interior volume. A high voltage a.c. electric power source is connectable through a high voltage step-up transformer between each of the catalytic plates whereby, when a.c. electric current flows through the catalytic plates and across the dielectric plate, the interior volume, being filled with hydrogen or deuterium gas, heat is produced within the interior volume for external use.


This patent describes what is, physically, a classic cold fusion device, but it never once mentions cold fusion, fusion, or any "LENR"-type reactions. They dress it up as a purely chemical reaction, and in fact, it's classified in B01J-19/08:

B01J 19/00 Chemical, physical, or physico-chemical processes in general

B01J 19/08 · Processes employing the direct application of electric or wave energy, or particle radiation; Apparatus therefor (application of shock waves B01J 3/08; generating or handling plasma H05H 1/00) [3]


This is what I meant when I said Rossi was actually being much more honest in his application, in that he was up front about what it was he was claiming to have accomplished. These guys have gone out of their way to hide their true intent, and engineered their application so it would be examined by someone who might not be familiar with the "cold fusion" claims, and who might then allow their patent to issue.


Also of interest is that I found this as a result of a version of this other application showing up in my work queue:


(WO/2009/137271) ELECTROLYTIC CELL AND METHOD OF REDUCING GAMMA RAY EMISSIONS


An electrolytic cell and a method for accelerating the reduction of gamma ray emissions from a radioactive substance. The cell includes a non-conductive housing and a conductive end member sealingly positioned in and extending from each open end of the housing. Gamma ray emitting material such as powder, granules or gases in an admixture with palladium black powder or particles are closely packed into the chamber. A longitudinal gas passage extends through each end member in gas communication with the chamber. Each gas passage is sealably closeable, one gas passage being connectable to a source of pressurized hydrogen or deuterium gas deliverable under pressure into the chamber to charge the catalytic particles. A distal end of each end member is connected to an electric power source wherein, when electric current flows through the chamber, the gamma ray emission count decays at an abnormally high rate.


Near as I can tell, they've taken a common objection to cold fusion claims (the lack of gamma radiation output), and decided that means they've found some great new way to shield against gamma rays.

That's like pseudo-scientific Judo, that.
 
Non-electric non-flame heat source

I was talking to a physicist friend the other day. He mentioned a nickel cell that can be used for a heat source. Just add hydrogen. Apparently constant heat or maybe a thermostat. No fusion, just a chemical reaction. When the nickel is 'consumed' they bake out the hydrogen and it is ready for another use. Anyone heard of this? I tried to Google it but just got nickel hydrogen batteries and fusion hits.

What you're talking about is generally called a thermal battery. Usually, such a device is activated and run once, at which point it is completely discharged. Using the approach you describe, the output could be throttled, and probably restarted. That said, I'd be dubious that anybody actually uses such a thing. It's too hard to store hydrogen for long periods.

Alternatively, there is such a thing as a nickel-hydrogen battery. If you Google "nickel hydrogen cell" you can find http://www.aero.org/publications/thaller/thaller-1.html , which deals with a nickel-hydrogen battery used in space applications.
 
Thanks for the link

I think this was a non-electrical heat source. Might have been obsolete for awhile. Will check with my source.
 
If someone were to demo a "cold fusion reactor" for investment purposes which was an outright fraud, how could it be done?
 
Thank you, pedrone, but I was looking for a method of faking cold fusion, not an example.
 
Questions made to Andrea Rossi:

How many e-cats are in continuous operation today?

Andrea Rossi: 97


How many geographic locations are e-cats running today?

Andrea Rossi: 4


Are there any e-cats running in the US with businesses you own or individuals you trust?

Andrea Rossi: YES

Oh the details are just astounding aren't they?

Not where they are, not what controls are in place, just "Nyah nyah, told you so."
 
If someone were to demo a "cold fusion reactor" for investment purposes which was an outright fraud, how could it be done?

It depends on exactly what the terms of the demo are. In the case of the Rossi demo, at least 3 ideas spring to mind.

1) The Swedish Report records the current to the main heater (1.5 amps - reasonably construed as 300 watts). The heater power supply could be modified to allow a higher drive upon receipt of an external command, with the readout also modified to show a constant output.

2) The Swedish Report mentions an auxiliary heater, but gives no details. There is no indication that the aux heater was turned on. (This despite the patent application claims.) A covert power source for the auxiliary heater is possible.

3) The Swedish Report analyzes the energy produced and compares it to the reactor volume to conclude that no chemical reaction is a feasible source of the energy. However, the reactor is contained in a bulky jacket which is claimed to consist of lead shielding and insulation. Instead, it might contain a hidden heat source. As noted in an earlier post, Ni-MH batteries are a possibility, but there are any number of others.

When a "skeptic" tests a miracle device, don't they assume, (but maybe don't reveal their assumption) that the device is outright fraud and the builder has gone to great lengths to deceive the tester? The main method to avoid being deceived is to replicate the device / experiment yourself under lock and key. If you do not replicate the experiment / device, you might as well take the inventor's word for his success (and send him three blank cheques).
 
Hi Jimmy42,

In the case of Rossi you can't replicate because Rossi isn't at that point. And it remains in the air if it will ever reach that point.

So far we have a power meter that is inadequate and no real measure of heat output.
 
More tests from the former chairman of the swedish skeptics society and the president of the physics society that decides the nobel prize....

There is a video above the article which shows the test.

The experimenters had free access to the PID controller box shown in the video, which is where the input power is directed. It appears from the video that two of the heater channels are in operation.

PS to those who wish to propose possible mechanisms of fraud... If you have no experience with controllers or power electronics please do a bit a research before making wild claims.
 
Um, so in prior tests they use a commercial power meter, what did they use this time? As in the kind of meter that a power company puts on the main to a house. Certain concerns were raised over this.
