   Won't catch me trying 15000 volts. As accident prone as I am I wouldn't
even get the HI YO out before I was toasted.

($30), you don't have a battery problem. The ac/dc adaptor problem is
solved, no more smoke in the kitchen. :)  

   You can get all the parts from Radio Shack to build one that produces
90 volts and it's harmless. It works on the same princable as a stun gun with
a lot less volts. The transformer is a 30v AC and it uses 3 caps. and 3 diodes
to produce the 90 DC volts. I've touched the rods many times even when wet 
and it gives a little tickle like the 27 volts but doesn't hurt anything. It
also makes 20 ppm in about 10-20 minutes. Cost about $10 for the parts if you 
don't add an box or anything fancy.
