I am very interested in cold fusion, and wonder what are your takes on it? Bogus science or something worth considering? And also, do any of you guys have any hypotheses for the theory of cold fusion?

Cold fusion does not exit.
Polywater does not exist.
N-rays do not exit.
Aether does not exist.
The Fifth Force does not exist.
You cannot talk with your pets at the moment of equinix.
Magnetic hernia trusses are crap.
Magnetic fuel filters are crap.
Magnetic water filters are crap.
Magnetic arthritis bracelets are crap.

Do you get the idea?

You will not have thinner thighs in 30 ays.
You will not have a washboard tummy.
It will not slice, dice, and julienne.

Do you get the idea?

There is no post-mortem escrow.
The government is not here to help you.
You won't get your money back.

Do you get the idea?

Uncle Al retorted:

> Cold fusion does not exit.

Only too true :-)

[snip list of previous extraordinary claims which were -not- followed by
extraordinary proofs...]

Guessing that "misogynisticfeminist" might be an earnest high school
student, I gloss: Uncle Al is our official curmudgeon, but his attitude
concerning delusional beliefs is understandable (and widely shared here,
if not widely expressed quite so bluntly). In particular, I have no
reason to think "cold fusion" has any more validity than previous "free
lunch" scams.

However, assuming you are writing a term paper or something like that, and
have time for a bit of library research, let me offer a few constructive
suggestions:

1. Get your local public librarian to help you search back issues of
(roughly in order of preference) Nature, Science, New Scientist, American
Scientist, Scientific American, or [if you must] Discover, Newsweek, etc.,
for articles or editorials on "cold fusion".

2. Your librarian can probably help you find books on psuedoscience in
general; if not, try to find a classic little book by the philosopher
Martin Gardner (later editor of the famous "Mathematical Games" column in
Scientific American):

author = {Gardner, Martin},
title = {Fads and fallacies in the name of science},
publisher = {Dover},
year = 1957}

There may even be a book on cold fusion itself by now, but if so, be
cautious; take account of the author's credentials, etc., in evaluating
scientific reliability. Generally speaking, as you would expect, books by
scientists are more scientifically reliable than books by journalists.
But since "the cold fusion phenomenon" is probably best thought of as
primarily a political/sociological phenomenon rather than a scientific
one, a good investigative journalist could probably write a perfectly
adequate book on this particular topic.

3. [Optional] I would have thought that the ArXiV

http://xxx.lanl.gov

would have some "general physics" expository papers explaining how the
original investigators messed up so shamefully, but I just looked and it
seems that there are none! There are some preprints mentioning "cold
fusion" in their abstracts, but few of these seem to have been published
in prestigious journals, and I'd warn laypeople against assuming--- quite
incorrectly--- that everything you might find in the ArXiv must have at
least some scientific merit.

4. [Even more Optional] Google permitting, search the web--- but note that
the cautionary remarks above about not assuming what you find has any
merit hold with even greater force! As a general rule, stuff you find on
pages hosted by physics departments at accredited research universities in
the U.S. are probably generally much more reliable than stuff you find
posted on some "enthusiast"'s website.

Possibly (4) would be worthwhile only if you decide you'd rather write
about "why so many people hold weird beliefs in the face of all contrary
evidence".

I assume you mean exist. Well, you are probably right, but why are
you so certain? The proofs that cold fusion is IMPOSSIBLE have as
much handwaving as the proofs that it occurs. Absence of evidence
is not evidence of absence.

If you can provide a solid proof that cold fusion is impossible,
please share it with us - if you merely have evidence that current
claims are based on the marvellous properties of snake oil, please
don't bother ....

Personally, I rate it as slightly more likely than FTL travel. I
intend to pay for my holiday on Arcturus's planets with the profits
from my cold fusion shares :-)

In the end, Science has to produce reproducible results, predict or explain

Hi Nick,

He is probably so sure, because there was never ANY evidence for cold
fusion, "except" of some destroyed lab equipment whose destruction
could have been caused by anything...


> The proofs that cold fusion is IMPOSSIBLE have as
> much handwaving as the proofs that it occurs.

????? There is no need to prove that is is "IMPOSSIBLE" to have cold
fusion. If you claim to have found a new phenomenon you better provide
some evidence for it.


> Absence of evidence
> is not evidence of absence.

Abscence of evidence is the best evidence of absence in science.

Otherwise, simply open up a press conference, tell the press that you
found, lets say, a 7th quark or so and end with "absence of evidence
is no evidence of absence". Is everything alright?

Yes. If you claim that cold fusion (except muon-catalysed) is pure
snake-oil, fine. But the original poster claimed that it was
impossible - that is a claim of a negative physical phenomenon (just
like the one that perpetual motion machines can't exist).

Now, the latter claim has been justified, at least in classical

What I am asking for is evidence for the commonly stated claim that
cold fusion is physically impossible. If you can't produce such
evidence, then please qualify that claim with "almost certainly".

There can't be any. There is plenty of understanding indicating that cold

What there can be is evidence that cold fusion has happened. So far, there
hasn't been any.

It happens all the time in a Deuterium container. The problem is
simply that the Coulomb barrier is so high that the tunneling rate is
utterly, utterly, utterly negligible for any practical purposes.

But it is certainly possible, and there is little doubt that it happens.
Every once in a while the nuclei in a D2 molecule will tunnel
through the potential barrier, and fuse.

You can even calculate the probability for it to happen.
It is just that the answer turns out to be -very- small,
so small in fact that the process has never been observed.

What is lacking is any plausible idea at all
about how that potential barrier might be lowered.
(except by using muons)

The normal context for that term implies a sustainable reaction,
not a few isolated events. It is often claimed that such a
reaction is physically impossible at NTP, and it is that claim I
am saying lacks proof.

If it does not, then let's hear it.

What do you mean by 'proof', and what do you mean by
a 'sustainable reaction'? The deuterium tunneling example
mentioned earlier is certainly sustainable; it just occurs
at an infinitesmal rate. Fusion reactions are not
self-sustaining in the same sense as fission reactions.
That is, one fission releases neutrons that can cause
another fission event. Fusion doesn't work like that.
If two nuclei can overcome the potential barrier provided
by their Coulomb repulsion, they can fuse, releasing neutrons,
gammas, alphas, etc. None of those reaction products directly
cause another fusion event between two nuclei.

Are you trying to make the point that one can't prove a
negative? Or that physicists sometimes use imprecise
language?

As others in this thread have said, there is no known
physical mechanism that can produce large rates of fusion
events at NTP for, e.g., deuterium. Similarly, there is
no known mechanism that can cause the 10^25 atoms in the
book in front of me to simultaneously tunnel one foot to
the right. No conservation law forbids it; it's just so
fantastically unlikely that we physicists tend to call events
like that 'impossible'.

I doubt if such a proof is possible.
What is known is that all the attempts to provide a background theory
for such cold fusion as have been claimed to have been seen always
involve gross contortions in our understanding of solid state physics.

You can make at least a handwaving argument
suggesting it must be impossible.
For tunneling of deuterium nuclei into each other
to occur at an appreciable rate they must be fairly close,
hence repulse each other strongly.
The repulsion energy can only be lowered by shielding:
that is, by confining electron(s) between the deuterium nuclei.
However, this involves confining electrons into a fairly small volume.
The inevitable result (by the uncertainty principle)
is that they must acquire a large zero-point energy.

And there you have it in a nutshell:
either the energy of repulsion of the deuterium nuclei
is to high for solid state energies,
or the electrons between them must have too high zero-point energies
to be compatible with their being confined
on a solid state energy scale.

It is possible to somewhat more precise,
but of course not to the point of making it a theorem,
