I'm sure the 200+ members, several of whom are on this list, will love that 
one. I'll let them reply to that one on their own time. As for me, I never 
professed to be perfect, but I, and my crew do things to the best of our 
continually improving abilities.

As a Group we have given *Signifigant* help to the coiling community. We 
have sold several thousands of MMC caps, and out of ALL of them, there have 
been less than half a dozen that failed (and it was operator error) and we 
replaced them, free.

We have hosted hundreds of classroom demonstrations, and our last Teslathon 
drew enough people to have *EVERY* store in the mall it was hosted in, 
report record sales for that weekend. We've build dozens of finished 
projects,have several more on the books, and are now the largest Federally 
licensed non-profit science and technology educational group of our type on 

What have you done?

Sure, we make mistakes, some of them rather expensive at that. But it's what 
we're here for. We take chances, make mistakes, and learn. If, in time we 
find that somethign we learned and published was incorrect, we fix it, 
promptly. I make mistakes every day, so what, I'm still learning how to run 
this company, and it didn't come with a manual. I think I'm doing a rather 
decent job, and with the combined efforts of the Board, Staff, and Members 
in 13 countries and 29 states, I think we'll do just fine.

>I suspect the 80kV rating was based on either
>severely flawed reasoning.

Actually, years ago when we built them we asked what the breakdown voltage 
was and were told "Don't worry about it it's something like 80kV" so that's 
what we wrote on the caps. When it came time to do the site, I went and read 
the caps, and it went on the site. I've never given it much concern.

Prove it, then I'll change the site, the caps, and the manual.


The above opinions are mine alone, not the Group's as a whole (though you'll 
find quite a few who agree with me). If you have a problem and would like to 
flame me personally, feel free to do so at cboden-at-thegeekgroup-dot-org, I love a 
good fight.
