[PhysOrg]Italian scientists claim to have demonstrated Cold Fusion - Page 7

post #61 of 68
If they are unwilling to describe what is happening inside their black box, it is likely because they are trying to scam investors.

"It's cold fusion. Srsly. Give me your money, but don't look in the box."

Meanwhile there is a coal burning engine in there, along with a hidden chamber filled with hydrogen and copper that can be brought out as 'proof' of fusion.

Fusing "the most common isotope of Nickel" (58Ni) with non-deuterium hydrogen (H) would make 59CU... which would immediately decay via positron emission to 59Ni, which has a half life of >70,000 years, ie. short enough to generate considerable radioactivity, and long enough to be awkward to store.

Why are there no radioactive byproducts? Because there's no fusion going on.
Right on Phaedrus. LOL.

Maybe after mass production in 2011, the world will just melt in 2012.

Apparently there is a paper, but they cannot explain or know exactly how cold fusion works.

If this is indeed legit, and they can find out how it works, they deserve massive credit, and have solved many of the world's problems.



Learn to read: "Rossi and Focardi say that, when the atomic nuclei of nickel and hydrogen are fused in their reactor, the reaction produces copper and a large amount of energy. The reactor uses less than 1 gram of hydrogen and starts with about 1,000 W of electricity, which is reduced to 400 W after a few minutes. Every minute, the reaction can convert 292 grams of 20°C water into dry steam at about 101°C. Since raising the temperature of water by 80°C and converting it to steam requires about 12,400 W of power, the experiment provides a power gain of 12,400/400 = 31. As for costs, the scientists estimate that electricity can be generated at a cost of less than 1 cent/kWh, which is significantly less than coal or natural gas plants."

There is no catalyst in this reaction, it is nuclear and does not need it. And it does have input energy.
I noticed the specs on your rig and was like !

Wow, no wonder you are an avid supporter of Arch Linux... >.>

If I knew how to start a cold fusion reaction I would not tell anyone else how to do it, if these guys really know they will want a monopoly on the tech.

Theoretically, we shouldn't have any left, but realistically it's still there and it's somehow catalyzing a high-aspect ratio growth via an unknown mechanism. The only mechanism we can think of is that is somehow stopping growth on the polar faces of the crystal structure by simply "capping" them. Hence, this is really an issue where we're not quite sure how to verify our theory besides the essential fact that with it we see high-aspect ratio and without it we see spherical particles. The theory is there but no way to verify a mechanism as of yet.

These people as alluded to before are hogwash. What I would really like to see is someway to show how much power they are putting into their system and actually see a power reading (pressure from steam or something like this) to just show that 400W in and 12000W out. Let them explain it over several years but show us this proof first.
The most open poster I've seen yet. It's actually not that rare to see science done with no explanation. A lot of science was done by random meddling, it's the best way to get results.


My favorite post from the popsci article on this:
Code:
Clay, you need to get up to date with developments in this field (!), 
including some knowledge of basic physics.

Please don't call it "cold fusion". There is nothing that "fuses" in these 
experiments. The term has led many researchers down a road that leads off 
into the weeds. The preferred term now is LENR (Low Energy Nuclear 
Reactions).

There is no currently accepted explanation of how excess heat is produced 
in these devices. But in my view, there is indeed a plausible mechanism. 
Atoms are composed of a primary mass and a secondary mass. The primary 
mass is simply twice the atomic number, and the secondary mass is the 
difference between the primary mass and that shown in the Periodic Table. 
Tungsten, for instance, has a Z of 74 and a tablular mass of 184. Its 
secondary mass is therefore 184 - 2*74 or 36 amu. This secondary mass 
("excess mass", currently ascribed to neutrons) has a foreign character and 
can be converted to energy by a simple, low-temperature process and can 
also produce energy spontaneously through radioactivity. The primary 
mass, however, is very stable and is not available for this type of conversion.

The atomic spin system is too complex to convert directly to energy. But the 
conversion could occur through an intermediate such as a massless particle. 
There is growing evidence, for example, that the flux of solar neutrinos 
affect radioactive decay rates here on Earth. (See scripturalphysics.org/qm
/adven.html )

There are two more massless particles that have not been discovered 
experimentally, but whose existence is suggested from extending the 
perodicity of the Periodic Table "backwards" (or "upwards") into the realm of 
less-than-atomic (or subatomic) particles. One of these could appropriately 
be called a "hydrino", but it is completely different from the hydrino of 
Randell Mills. THIS hydrino and hydrogen (protium) appear to be closely 
related, and may explain why hydrogen (in the form of water, 
hydrocarbons, metal hydrides, H2 gas, etc.) is a key player in the LENR 
phenomena.

[edit]I'm not going to post to their website though, I despise anything religious even if it's pushing science.
This isn't fusion as we think of fusion, apparently "cold fusion" as the old term was defined doesn't exist. I'm not saying this is real, but there are quite a few things that we know exist (or at lest we observe) but yet can't prove them or find any valid way to prove them.

For the record, I'm also highly skeptical of this. Still, that's not deterring them so good on them. If they're wrong we're no worse off.
This.

If cold fusion is achieved, it will most likely be done in California or New Mexico.

Hopefully they are on to something, but 2 scientists at the U of Bologna?

We'll see.
