- "Cell Power Measurement 101" states:
-
-
- == "I keep looking a photographs of supposed "cold fusion" cells
- == and all I see is two clip leads.
- == Folks, you have to have four leads to make a decent measurement.
- == (McKuber seems to do this right but have not seen any one else.)
- == Two leads carry the current, two connected to the cell on the other
- == side of the clip leads measure the potential across the cell.
- == These leads carry very small current.
- == There is lots more to worry about, but the above will likely get you
- == a 1% measurement. For more accuracy you have to take Cell Power
- == Measurement 201, 301, 401, ... ."
-
- This truth in this is worth repeating and further considering,
- since there seems to be diversity in opinion as to what exactly is
- "equal input electrical power".
-
- Quaerie:
-
- Some experimentalists do not give a clear indication of what was the
- power input to the "control" cell. That is, was the electrical power
- input (from a black-box consideration) equal for the two cells.
-
- For example, one group applies an electric power to the "reactor"
- cell of I0 * V0 watts, but applies only I0 * (V0 - x) watts to the
- "control". x here is circa 1.4, and has been discussed elsewhere.
- Another group uses identical input powers. Can there be uniformity
- and a clearer distinction?
-
-
- When readers hear 70% excess heat (or whatever value), unless it is
- clearly stated, many presume that the electrical input power was the same
- for the two (or more) cells.
-
- Perhaps there can be a distinguishing label as to this Quality Factor
- characterizing any given system, which will clue a reader into *** how ***
- exactly the experiment was conducted. Any thoughts?
-
- For example, when calculating, and posting, the "temperature
- differential", or the "delta-T" between the two systems, as an alternative
- equal electrical power input can be delivered to both the reactor and the
- control cell. The description can then report the "equal power input
- delta-T" and then also calculate the further derived increase in putative
- excess heat by the addition of the "x"-term? Equal power input delta-T
- could clue in the reader as to what was done.
-
- It would interesting to know what the folks here think.
