Reminds me of the time when I was in high school and was trying to improve the output of a Jacob's ladder. Had constructed a glass capacitor out of some loosely stacked metal plates and panes of glass. Worked great until the high voltage found the flaw in the glass and it self destructed. perl -e 's==UBER?=+y[:-o]}(;->\n{q-yp-y+k}?print:??;-p#)' On April 13, 2015 7:26:14 AM PDT, Reverend Fuzzy <pastor@xxxxxxxxxxxxxxxxx> wrote: >I am intrigued by this design. >Do you remember which book that was? > > >> -----Original Message----- >> From: Tesla [mailto:tesla-bounces@xxxxxxxxxx] On Behalf Of b alex >> pettit jr via Tesla >> Sent: Monday, April 13, 2015 5:59 AM >> To: tesla@xxxxxxxxxx >> Subject: [TCML] Glass Plate Capacitor >> >> Hello All, >> I have been in the process of getting an old build operational >again.I >> constructed this RSGTC back in the mid '80s based on info from a book >> published in 1920.
