Wow! Swift response!

Yep, the translation of plate separation, even mean separation, can  
be understood from:

    C = epsilon A/d

    q = C v

so:

    v = q/C = q/(epsilon A/d) = q d / (epsilon A)

thus v is proportional to d. The energy comes from mechanically  
separating unlike charges, or conversely, letting them attract each  
other upon return.
