well it would if you stood in the wrong place! :smt005

Absolutely awsome, no real useful application for them as of yet tho.

Hmm, theres shocking them, and theres SHOCKING them! I dont think you would get much of a belt through that anyway, yeah it would hurt alot but im not sure it wouldnt kill you, resistance of air is far too high to carry enough current to kill you i would have thought, unless you went and touched the top of it.

i can bring them to the brink of death, i have no problem with that! killing them cost's tomuch now a days

so all these people who die from being struck by lightning then.... :smt003

nikola tesla was an absolute legend, in a completely bonkers mad scientist kinda way.

But lightening is on a much much higher scale, about 300kv across the same permeability of air, so current will be higher. Also the point of contact is usually through the head, neck or shoulders, usually causing a heart attack. Dont get me wrong, if you got struck by a tesla coil, it would hurt like a bitch :smt009

Nikola Tesla was a great scientist indeed! Completely unrecognised for his work with monkeys like Thomas Eddison discrediting him because he didnt like his ideas. Theres some vids on you tube about him actually and some of the stuff he came up with

two minutes + google = at least a couple of pages about tesla coils in the 500kV range!

i wouldn't be stood near one. i did know someone once who built one but never got to see him try it out.

Have you seen him since? :smt005

Dont think i would stand near one either actually. Since they use a step up transformer i do believe theres only so much current you can draw.

Just looking at some theory on this, the power (VA) across each coil in an ideal transformer is the same, so if you stepped the voltage on the second coil up from the first, you would have a proportional decrease in current on the second to mantain equal power on each coil, so you might be ok?

what ever you used to read up on that must have been the dryiest read of your life :smt015

Quite interesting i thought myself, but then thats why i study electronics :smt004

If you must know the book, in fact i should refernce it, its 'Electrical Circuit Theory and Technology' second edition, by John Bird, ISBN 0-506-4989-5 printed by Newnes publishers. Page 317 is where you can find that statement.
