Re: [TCML] 4'-5' tesla coil sparks?

[jhowson4@xxxxxxxxxxx]

You might be right Ed, 
Were you the individual I spoke to on the phone about a Faraday cage for our Van De Graff in early April? 

They did specifically tell me that they were going to buy everything and that none my my equipment stash was needed. They do also seem moderately serious about trying to do this project. They have a large exhibit on energy and the like that is beginning in June. 
I think the answer to all this might be to simply assist in building a small table top coil that outputs ~1' sparks or something in that range then put it into a high mesh Faraday cage display case. Or just somehow convince them to buy a coil from people who know what they are doing, ie. Resonance Research. 

I am still going to finishing the designing this one though (I like designing stuff), also I have been thinking about redoing my garage coil for some time (its getting old) and is probably really far off from anything close to max efficiency. =) 

On that note, does anyone have a table outlining optimum resonant Frequency related to input power? 



Thanks, 
John "Jay" Howson IV

Hi Jay, 

It has been my observation that there is no one at the museum who knows 
much of anything about Tesla coils or the rigging of Tesla coils. They 
have talked about installing a Tesla coil for years and one of the 
museum directors visited my lab here in Brockport (18 miles from the 
museum) during a Teslathon several years ago to get an idea of what was 
involved, but nothing has ever come to fruition. I visited the 
development warehouse last summer at the request of a friend who helps 
out there concerning Tesla coil/Van de Graaff generator safety and the 
response was a bit lackluster, to say the least. The Van de Graaff 
safety issue arose as a result of the unit that you folks built at RIT. 

Another coiler from the Rochester area put on demos at the museum at 
various times for a year or two using his own equipment. He did not 
mention if there was any compensation. 

I believe that they are looking for donated time and equipment, which is 
fine, if you are willing. The insurance and liability question is one 
that I never asked, because things never progressed to that point. Be 
cautious.

I presume that they know all about rigging and such, they are a reasonably large museum. The only question they could not readily answer was about the RF ground and the grounding of the Faraday cage to eliminate the interference. Is that even possible with a reasonable mesh size. I may take an RF meter and one of my small coils and do some tests just to see how much actually escapes from different types of cages.
