In my electrolysis research, I found that the wire leads for my
control runs made a significant difference. Obviously, thinner wire
connecting to the joule heater resulted in less power being
dissipated in the joule heater and more being dissipated in the wire
leads. I had initially thought the wire was thick enough, but I
wasn't seeing as much heating as I expected. I switched to thicker
wire, and then I saw better heating.
That brings me to Jet Energy's (Mitchell Swartz) claims. His active
material has a much higher resistance than his control
resistance. Could the apparent excess heating in this device be
related to the same phenomena (i.e., power dissipation in electrical
leads vs. where the measurements are taking place)?
Thank you for asking, Jack. Good questions.
The active materials are not always higher electrical resistance
than the control resistance. We try to make them equal,
but the CF/LANR component undergoes changes for several reasons,
and the controls are often changed to get them as equal as possible,
or multiple thermal ohmic controls are included.
On the leads.
We use 1 mm diameter leads into the CF/LANR components.
The PHUSORs have 1 mm Pt lead and 1mm Pd leads
which are shown in the papers from ICCF10.
That is mentioned in detail, and shown in photographs,
in Swartz, M., "Can a Pd/D2O/Pt Device be Made Portable to Demonstrate
the Optimal Operating Point?", Condensed Matter Nuclear Science,
Proceedings of ICCF-10, eds. Peter L. Hagelstein, Scott, R. Chubb,
World Scientific Publishing, NJ, ISBN 981-256-564-6, 29-44; 45-54 (2006).
The NANORs have similar size diameter of the leads and
are pure copper. They were designed so that input impedance would
not be an issue,
and their impedances are measured as well. The CF/LANR device's
electrical impedance
is usually measured by four-terminal measurement.
Also the excess heats are verified by several independent
systems as discussed in the papers (three usually, for the NANORs).
