Why probably not quite right????  Any evidence to suggesst this??

I believe there is no return current problem with a single charged 
sphere hanging in space.  The return current is the displacement 
current.  As the charged object breaks out and conduction current 
bleeds out into space, there is a corresponding reduction in the 
voltage on the object.  Hence, there is a dD/dt back to the object to 
keep things in balance (keeps Norton happy).
