[NewCandle] Back emf ?

[Jones Beene]

We have long heard about using so-called "back emf" in
efficient motor design or transformers. 

AFIK there is no firm proof that it can ever produce a
COP>1 in that situation ... there are just too many
loses to be overcome -- but a valid question: is there
an imaginable situation where where "charge" can be
recycled so that it can be gainful? The Bedini battery
thing comes to mind, but there is no real proof of
gain there (or is there?)

Anyway - the only reason that *ions* would seem to be
ideal for recycling charge is ... well ... they are
already charged but 'bound' and in some way this seems
like it should be exploitable- i.e. the recycled
charge being used to 'unbind'. 

IOW if the "work" that goes into creating charge
involves overhead which can be avoided by recycling a
charge before it has been fully neutralized, then
ionic solutions offer a greater hypothetical path. 

Can someone help me with the wording here? ... I have
an idea in mind but am having a hard time putting it
into words. Maybe this little video will help...

Not even sure if the underlying concept of back emf is
the same thing - when applied to electrolysis, but
this is provocative....
