Notes from Jed Rothwell:
1. This document is intended to augment the Fusion Technology paper
by Mills & Kneizys. Fusion Technology is carried in many major
libraries, for example, the Boston Public Library, and the
M.I.T. science library.
2. Subscripts are shown with square brackets: H[2]O.
Purpose:
Many people have heard of the light water excess energy experiment
reported by Mills and Kneizys in Fusion Technology. (1) By January,
1992, this excess energy effect had been reproduced by at least a
half-dozen other groups.
Even though the experiment is simple and apparently highly
reproducible, many would-be experimenters might be deterred from
trying it because of the well-known history of difficulties with
the heavy water palladium-platinum approach of Fleischmann and
Pons.
Even though Mills et al do not think that their excess energy is
due to "cold fusion" -- they have an elaborate theory of shrinking
hydrogen atoms to explain the excess power -- their experiment
_was_ inspired by the Fleischmann-Pons announcement.
The purpose of this brief collection of experimental protocols is
Page 1
to encourage others to try the Mills experiment and perhaps go
beyond it in their investigations.
How to Begin
The first order of business is to read the experimental part of the
Mills-Kneizys paper in Fusion Technology to familiarize yourself
with the basic approach.
Don't try any fancy pulsed input power in the beginning. Stick with
continuous (DC) input power. Don't be concerned either about the
exotic theory of Mills and Kneizys. Their theory may be wrong or
right, but it's the validity of the experiment that's important at
the moment. Other theories -- including "conventional" cold fusion
mechanisms working with the trace amount of deuterium -- might be
invoked to explain the excess energy in this light water
experiment.
Conditions that should be employed:
1. The volume of solution could be from 100 ml to 1,000 ml in a
vacuum-jacketed glass dewar cell. Note: Some people have tried a
non-dewar cell -- a heavily insulated glass beaker with plastic
materials to give the same insulating dewar effect. The cell
should be closed at the top with a tapered rubber stopper.
2. The electrolyte should be: 0.6 M aqueous K[2]CO[3] of high
purity.
3. The electrolyte should be stirred continuously with a magnetic
stirring bar to ensure temperature uniformity.
4. The nickel cathode does not apparently have to have the exact
configuration of the "spiral wound" sheet described by Mills-
Kneizys in their paper. It could be just a flat sheet of nickel,
but the ratio of the _total surface area_ (i.e. both sides) of
the nickel cathode to the surface area of the platinum anode
should be no less than 20/1.
5. The anode is of platinum wire, 1 mm diameter. Mills and Kneizys
used a spiral-shaped piece 10 cm long.
6. Above all, avoid impurities and contamination of the cell
materials, whether in handling or in environmental conditions.
Particularly insure that no organic contaminants are in the cell
or on the electrodes. (Don't forget that remnant soap film could
be a problem!)
7. Dr. V.C. Noninski, who has replicated this light water work (2),
recommends:
"Before starting the experiment, mechanically scour the platinum
anode with steel wool, soak overnight in concentrated HNO[3],
and then rinse with distilled water. Remove the nickel cathode
from its container with rubber gloves, and cut and bend it in
such a way that no organic substances are transferred to the
nickel surface.
Preferably, dip the nickel cathode into the working solution
Page 2
under an electrolysis current, and _avoid leaving the nickel
cathode in the working solution in the absence of an
electrolysis current._"
8. Before attempting to run the cell to demonstrate excess energy,
reverse the cell polarity for about one-hour to anodize the
nickel cathode. However, Professor John Farrell of the Mills
group has said that 0.5 hour of this treatment is adequate. He
says this "electropolishes the Ni."
9. Use distilled H[2]O.
10. There have been claims and counter claims about whether the
experiment will work in "closed-cell" mode with a catalytic
recombiner. Begin your work without one to be on the safe side.
Professor Farrell and, independently, Dr. Noninski have
measured the oxygen and hydrogen evolution in the absence of a
recombiner and find these gases in the expected quantities,
i.e. unsuspected recombination is NOT causing the excess power
effect.
11. The current density on the cathode should be on the order of
_one milliamp per square centimeter_. This is very low compared
to the Pons-Fleischmann heavy water experiments.
12. To calibrate the cell, introduce a pure resistance heating of
known power by using a 100 ohm precision resistor encased in
teflon tubing.
Simple Analysis:
The basic goal of the experiment is to demonstrate that
significantly more heat emerges from the cell under electrolysis
than the joule heating of the cell. This is how the basic analysis
works:
The cell has a particular heating coefficient (HC), which can
be determined by employing (in the absence of electrolysis) _pure
resistance heating_ by an ordinary precision resistor with an
applied voltage. One might find, for example, that the HC of a
particular cell is say 25 C/watt. This means that for a watt of
input power, the temperature of the liquid contents of the cell
should rise 25 C above ambient. In this regard, keeping the ambient
temperature stable is important; this is a source of possible error
in the experiment.
The heat input to the cell that would ordinarily be expected
from electrolysis (the so-called "joule heating") is given by the
expression:
(V - 1.48)I
where V is the voltage applied to the cell, and I is the current
passing though. The "I x 1.48" quantity here is the power lost by
electrolytic production of oxygen and hydrogen. Because the cell is
open to the atmosphere, this "power" in the form of potentially
recoverable chemical energy simply escapes the cell.
If, for example, the current is 80 mA and the applied voltage
is 2.25 volts, the joule heat input to the cell would be 61.6 mW.
Page 3
[An example used by Professor Farrell]. If the HC were 25 C/watt,
the expected _temperature rise_ of the cell due to the 61.6 mW
input power would be 25 x 0.0616 = 1.54 C. If the temperature is
observed to rise any more than 1.54 C, an unknown excess power
source may exist in the cell. If, for example, the temperature were
observed to rise 3.08 C, rather than only 1.54C, this would
represent 100% more heat than 61.6 mW coming from the cell, that
is, 133.2 mW.
Excess powers on the order of 100 to 300%, calculated in this
manner, are said to be readily achievable. As Professor Farrell has
said, "We have never NOT gotten the effect." [With these general
conditions.]
Caveat:
This has been a tutorial for beginners by someone who has not
done the experiment himself, but who has talked to the people who
have. You should be able to go off on your own now and find bigger
and better ways to do this. You might begin by trying pulsed power
input, which supposedly increases the output. If you are a cold
fusion skeptic, you should really relish this experiment! It offers
an easily reproducible effect. If you can find a _trivial_
explanation for the excess power, think how famous you'll be! More
likely, you'll become a "Believer" -- or at least a very frustrated
skeptic -- so watch out!
