reverse polarity -

[Tessie McMillan]

Thanks, that is what I was trying to say. I'm aware that charge always 
flows in the same direction but crudely inept at how my cars function 
mechanically. I'm sorry to say the only interesting thing I can add to 
this discussion is a totally NAC tangent that batteries are all around us.
I can tell you how nerves conduct impulses and how the heart beats, for 
example. They are battery systems as well.
