But why not a simple graphite from a pencil? The bone is a fixed structure,
it won't stress the fragile graphite. And they can used at will, since they
are extremely cheap. I am focusing here on extreme cheapness.

Oh, damn, it also oxidizes... and quite fast!

The can handle molten iron and nickel. I think rather than a heater, put
the bone inside one of these, filled with molten metal. If there is self
sustaining, it will just stay there, hot, unless with a run away explosion,
which will be amazing.
The material does not seem to be expensive so, not

The problem with using either the SiC tube or a carbon rod is the loss of the
magnetic field.
SPP formation is opto-magnetic. Resistance wire coils have enough amp-turns to
provide a small axial magnetic field, and this appears to be important. See the
papers on the Letts/Cravens effect – a
thru the
enclosed fuel.

Daniel, I got an email response to you from Dennis Cravens (who reads
Vortex-l):
One easy way is a carbon welding rod. ---Cheap and most have copper
coatings that can be easily pealed off and also be used for easy
connections. They are also useful for current shunts.

Can't you use W as a heater?
Bob, why didn't you continue with until 1200 outside, I thought you were
following Hank's advice. But, suddenly, the experiment stopped. Can you
explain that?
My opinion is that this was the best documented, reported, and
instrumented Parkhomov replication experiment to date. There are sure
to be better experiments to come, but lets give Alan his due for
putting together a good experiment.
Hear, Hear!
My comments sounded more negative that I
I think you are being unduly unkind in observations of Alan Goldwater's
experiment.
Alan had previously done a dummy run with a thermocouple inserted into the
center of the core and had a calibration curve showing the internal
temperature of the reactor vs. the temperature on the outside of the
There were a couple of reasons. First, Alan was at near maximum power when
the reactor tube outside temperature was 900C and the internal core
temperature was over 1200C. The Kanthal A1 heater wire would have burned
out by the time the reactor tube temperature could have been driven to
1200C,

I was interested in how the pressure behaved in the experiment. To my
despair, the experiment ended way to soon to see the pressure flatline. The
pressure was still going down at the end of the experiment. Parkhomov ran
the experiment in his living room for 3 days, Alan Goldwater was concerned

Finlay asked a similar question. The answer is in the thermal model for the
mounted area of the thermocouple.
The thermal model for Alan's thermocouple, mounted on the reactor tube, is
different than
Tungsten has a very high melting point, but it suffers badly from oxidation
and will fail at 1000C if exposed to O2. Kanthal A1 is one of the best
alloys for a heater coil that can survive in the presence of O2 (leakage)
and it is reasonably ductile for forming. Ductility is important because

Bob,
it seems that Parkhomov is low on budget. Isn't there a cheaper way to heat
that? Like, removing the graphite from a pencil and using it to heat?

MFMP didn't show COP1, with the dog bone test, last night
It was a bit more disappointing than that. They didn't seem to have a
clear understanding of the protocol. They leveled the temperature at 855
C, initially; then decided it should be leveled at 875 C. Then they
decided to raise it
