Is your point that no new electricity from wind or solar needs to used to charge the battery. Rather the chemical reaction just keeps producing electricity until the chemistry is used up?— Which could take years ... because the efficiency of the reaction—is much much greater than the efficiency of other known chemical batteries.
It would be a new chemistry, a “super-resonating” chemical reaction. That’s what Pons & Fleishmann discovered. Their mistake was that they never shoulda used the word ‘nuclear’.
