I'm still digesting this useful information and some of its leads Bob … That the kernel of an idea of holding a battery resonant seems to hang together even if a bit tenuously bodes well … to fit the xtals into the picture gets harder and so I'll go with a few instincts, a circuit or two, and the reasons why, in the hopes that if any see anything obviously wrong you'll post before I waste time and money. Having said that I don't like shooting arrows with no target to aim at!
I believe parallel resonance is synonymous with harmonics and the ½ wavelength .. that is a series of frequencies 2nd 4th 8th
whilst series resonance is synonymous with overtones or 'odd harmonics' and the ¼ wavelength.
3rd 5th 7th 9th examples of this can be seen in transmitting xtals cut and series driven in overtone mode this sentence
Crystals can be operated in a mode called overtone mode. Third overtone, and fifth overtone crystals are commonly used in the lower VHF
range 30 to 150 MHz. Seventh and ninth overtone crystals are also used,

http://www.northcountryradio.com/PDFs/070302007.pdf It is perhaps no coincidence that shifting to another field altogether what heavy power electricians call 'commutator action' follows the same sequence in crude terms regard this as EMF being harmonics and Bemf being overtones for instance.
This extract from another field points out the same sequence
Fourier analysis reveals that a waveform, like a square wave, that is anti-symmetrical about the 180 degree point contains only odd harmonics, the 3rd, 5th, 7th, etc. Waveforms that have steps of certain widths and heights can attenuate certain lower harmonics at the expense of amplifying higher harmonics. For example, by inserting a zero-voltage step between the positive and negative sections of the square-wave, all of the harmonics that are divisible by three (3rd and 9th, etc.) can be eliminated. That leaves only the 5th, 7th, 11th, 13th etc. The required width of the steps is one third of the period for each of the positive and negative steps and one sixth of the period for each of the zero-voltage steps
Its from this paper
http://en.wikipedia.org/wiki/Power_inverter viewed this way terms which seem odd like splitting the negative used by Gray start to make sense .
Bob I really don't know if the negative resistance effect of a sulphated battery is due to crystals …. nor do I really know if the harmonic EMF and overtone counter EMF armature reaction relates .. I think it does
That all aside for reasons I've outlined I believe at least part of the equation is holding a lead acid battery in series resonance and so exposed only to the overtone progression regard less of load .
At first it seems a difficult proposition but due to my idle nature my instinct is to seek out braver souls than me fighting the same problem in different area's and then pillage and plunder... must be the Viking in me!
Thinking along those lines brought to mind 'coiler's' …. those who love their Tesla coils, these guys have spent years trying to devise circuits to constantly adjust to and hold ¼ wave resonance can I adapt one of those perhaps ? Here's a few examples
http://danstrother.com/elysium/ or even simpler (perhaps)
http://www.rmcybernetics.com/shop/induction-heater-circuit also the implications of the conditioned SS pipes you posted is just starting to sink in Bob .. as in it might be a stable Xtal structure that could also split off the overtones ?? Its simply has also got to be investigated, your post reminded me of this clip Aaron posted some time ago regarding conditioning the tubes
.
https://www.youtube.com/watch?v=Lo6iS9LIdmQ I'm going to let these thoughts percolate a little while , Then Its shopping time .
In the mean time anyone with any specialist knowledge of breaking down signals or heavy power into its overtone and harmonic components even if it at first doesn't seem to relate for example although this guy doesn't seem to know an overtone from a harmonic this -
http://www.transcat.com/media/pdf/PowerHarmonics.pdfSo to be clear what I have in mind is some knowledge be it practical, mathematical, or science based that will enable us to control and utilize this effect which it is clear happens in every field of electrical work (all be it under different names) anything you girls and boys might post I promise will be gratefully hoovered up as long as I have the nous to understand it.
