Hi Chris and Mark,
Just FYI along these lines.
The test cell I had built to mimick your setup never achieved a state of being endothermic. Every measurement I made with a digital thermometer indicated that the test cell was always running approximately ONE degree (F) above room temperature. These were side by side direct measurements in my temperature and humidity controlled basement.
This disappointed me a bit because I expected that once the zinc was being regenerated that the temperature of the electrolyte solution would drop below room temperature. This never happened.

Yes, RR, Thanks, I acknowledge what you said, just doing some verification.
In college chemistry we learned that all reactions have an energy balance. Either the chemical
reactants provided chemical potential energy, which when they ran out stopped the reaction or
energy was provided externally, like by electrical current, in either case the reaction would also
stop if reaction byproducts (exhausts) built up in the solution. Just like a Perpetual motion
machine that will break down or wear out, side reactions from contamination can be expected
to build up in the Linnard system. What is suprising is that the two reaction products have a
rather large combustion energy between them and also an ignition energy between them and
that means they are a fuel and oxidizer pair.
Catalysts lower the reaction energy barrier between reactants but do not supply
the chemical potential energy to make the reaction proceed. So where does
the extra energy of this reaction come from? Endothermicity was the last hope
of explaining the reaction in usual terms. That leaves us with an explanation of
an "exotic" energy source powering this reaction.
While the endothermic explanation would be more theoretically satisfying. An
exotic energy explainantion would make the the reaction much more valuable,
much more ZPE like and a much better potential as an energy supply competitor
to conventional systems. Of course if is it getting it's reaction energy somehow
from a more mundane source it's value drops significantly, even though it might
still have some valuable to someone maybe trying to reform something like coal
slurry to hydrogen + CO2 or something. So I doubt that it has no value and it
appears as it has significant value.

I as you, am not too exited by the prospect of having armatures or hobbyist trying
to store large amounts of hydrogen, even though I would be willing to purchase
a commercial hydrogen storage subsystem - hopefully fully debugged. I am
equally non-exicted by the concept of burning hydrogen gas in an ICE internal
combustion engine. So I am generally awaiting the automotive mass production
of hydrogen fuel cells to bring the price down and eliminate the need to store
hydrogen. Once this happens, I assume these HHO production systems are
really going to take off. As I have said in another post 16KW vehicle fuel cells
are ten times bigger than the 1.5KW continuous part of the demand for electrical
energy that the average home consumes. (excluding variable heating energy).
So I am continuing to be interested in what you and others are finding with this
Linnard (like) system. And I am definitely hoping for it's success. Good work
so far!
