A Followup on Surplus Caps...

I called William today and had a nice chat with him. Turns out he 
lives in Tennessee, but spends much time working at the DOE facility 
in Paduccah, KY. There are a couple of capacitor "flavors" available. 
They all sound like power factor correction type, with most in the 25 - 
50 uF at 2500 - 5000 Volt range. However, there are also 14 KV caps that 
were used in the switchyard. Unfortunately, William didn't have the 
specific values for these available (yet), but should have the 
information shortly.

The current situation is that these may become available IF DOE decides 
that the regulations for managing PCB-laden equipment permit them to be 
resold for electrical usage (which looks favorable....). However, knowing 
the glacial speed at which governmental agencies work, it's not clear 
when they will decide one way or another. 

William has forwarded all of the E-mail posts regarding interest in these 
caps to the DOE engineer who's responsible for disposal/disposition of 
these. The lower voltage caps would make dynamite filter caps, and the 
14KV ones might be applicable for Tesla work. Any other potential uses 
for these that you guys can think of???
