Re: [EVGRAY] Lithium Ion Capacitors?

Body

Bob, I hear you regarding the Tesla Switch, someday I will build it.  
Ha, Ha.   I remember calling John Bedini early 80s and ordering the same 
switch schematics series/parallel switching. Built it and over time the 
batteries ran down.  Definitely not O/U.   I know, times have changed 
and really great technology gives reason to revisit old projects.  Norm
