Meant "input power plus heater power." Sorry.
Do I have this right? See the graphs on this page:
http://jlnlabs.imars.com/mahg/tests/mahg2c.htm
In the graph for test run 76, the fluctuating green line is water flow
in liters per minute. The red and blue lines do not fluctuate. They
are "temp input" and "temp output" which I presume means cooling water
Don't think so. That's the water he's running the reaction with; it's
not 'disinterested' "cooling water".
The speed of the reaction depends on how fast water goes in and comes
out. The rise in temp of the dissocciated/reassociated water depends on
the reaction and may be relatively independent of the flow rate.
He's adjusting the input temperature with an outboard cooling unit, so
the input temp should be fixed; again, the output temp depends on the
reaction and will typically be a fixed offset above the input temp.
Note that he's also playing some games with a "temperature offset" to
compensate for initial conditions being different from the long-term
conditions; with temp variations this small that bit is probably worth
careful scrutiny.
Perhaps this is a minor issue, but this gadget appears to violate the
first law of thermodynamics.
I'd say that'a a pretty major point, actually. Electrolysis and
recombination doesn't leave a lot of room for the "ZPE fairies" to
flutter in during the badly-understood parts of the reaction in order to
work their magic and create excess heat.
Up until the present, when an experiment appears to violate the first
law, it has generally paid off to look for either (a) a previously
overlooked energy source (e.g., cold fusion) or (b) look for the mistake
in the setup or the calculations. Only after one has been all over
points (a) and (b) does one typically start looking into a repeal of the
first law of thermodynamics. This is very much like searching for a
mundane explanation of an apparent miracle -- so far it's been a good
strategy...
inlet temperature and outlet temperature. (Not the cell temperature.)
As I said, I don't see how and why did they pulled this off, but
perhaps there is a good reason. One must be careful not to make snap
judgments about experiments of this nature.
Here is a general introduction to the theory:
