with the linemans faraday suit, it's not exactly safe, but a lot of the danger is taken away.

maybe he'll nod off and bump his fore head on the helmet thingy? that could be fun...

also, here is a picture of Mr. Tesla reading a book by the light of one of lamps, not giving a crap.

also, as I understand it, while the coils produce MILLIONS of volts, the amps, and the frequencies involved denote them not being THAT dangerous.

I'm sure getting hit directly by one of the electrical "feelers" would make for not having a good day, but the skin effect is not that severe in this case.

would any Fark expert Electrical engineers care to elaborate?

It only takes a few milliamps of electrical current to stop your heart. The trick that Blaine is using is to surround himself in a cage suit so that most if not all the current passes around him and not through him. Something that guys that work on high voltage lines have done for decades. The only trick I can see him doing is sleep depriving himself for 36 hours.

well aware of the faraday concept and the linemans's faraday suit. which, I myself mentioned right at the top of the thread.

I'm more concerned with the notion that the secondary coil of the tesla device, despite all it's sparkly theatrics is not as dangerous as the primary air coil.

that's what I recall, The Faraday suit isn't exactly necessary, but certainly helpful if you are going to be exposed for that long. localized tissue and nerve damage is possible, but at such frequencies, you don't even really feel it.

sparkeyjames: It only takes a few milliamps of electrical current to stop your heart.


As long as your skin isn't wet, the limit of safety is on the order of tens of milliamps at the skin, and higher frequencies require substantially larger currents to actually cause ventricular fibrillation; the voltage-sensitive channels in nerves and muscles can't respond fast enough before the direction of current reverses.

More dangerous is simple heating of the body due to dissipating the power, and the associated tissue damage from heating.

Sorry 'bout that. Singing tesla coils - they play stuff like the Dr. Who theme, AC/DC, or Popcorn on 'em. Found the link to the guy who built the faraday suit. The suit is tricky, because any gaps will arc from one part of the suit to another, so audience participation's not a good idea. Must be fun to dance between two 10-foot-tall Tesla coils, drawing lightning towards one's fingertips merely by pointing at the desired coil.

They also have a small (human-sized) Faraday cage that's safe enough for audience participation, just keep your fingers inside the cage. The cage has gone through a few revisions; in some of the videos I linked to, they used a thicker mesh that was too fine to stick a finger through, but was also difficult to see through. The reflections in the corners and sides suggest they're now using plexiglass on the inside, and a wider mesh outside for better visibility - even if you trip over your own feet while dancing, you're not going to stick a finger out of the cage.

Anyone who really doesn't like David Blaine for this or that, or that his feats aren't really that impressive should check out this Ted talk he did where he explains himself:

http://www.youtube.com/watch?v=XFnGhrC_3Gs

He still is a pretty insufferable dick sometimes, but the shiat he does is like a modern day Houdini. Yeah, it's not magic, but it takes incredible amounts of patience and physical toil to do the things.

Or you could watch this, which is hilarious

For one, he's wearing a Faraday Suit, which redirects the electricity around him. Also, AFAIK, you're more or less right, high voltage, low amperage just sounds scary.

Hopefully Tesla, as he was the true genius, and Edison was just a ripoff artist.

Hopefully by then, they'll fix the whole 'Marconi invented the radio' bullshiat, too, since the Supremes sett;ed this shiat for good back in 1943, yet I was still taught about Marconi in school i the 70's and 80's and never even HEARD about Tesla until years after I graduated, with the exception of playing with a Tesla Coil in 6th grade. I guess this is what we get for letting Texas choose our school textbooks...

We had more fun with the oil burners w/10K volt transformers. Just form a long chain of people holding hands out into the hall. The guy near the burner sticks a wrench or some other metal object into the arc. The guy in the hall grabs the wrist of the nearest victim and gives them a little zap. Lots of fun, and kept our area of the hallway clear of slow walkers for a long time.

That's amazing. Amazingly like the electricity demonstration they give at the Boston Musuem of Science every day at 11, 2 and 5.

Back in the day my wife had a high school friend, John, who staged an ever-more elaborate haunted house every year. He would arrange to use the basement of one of the grander mansions on West Newton Hill and hired local special needs people to dress up as monsters and jump out of closets (they loved it). I used to lend him my human skeleton to use in the show, but that's a different story.

One year I brought my father-in-law the day before Halloween for a preview. John had been collecting props for years and had in his possession two impressive-looking pieces of equipment, the "Jacob's Ladder" as seen in Frankenstein's lab and some oher monstrosity the name of which escapes me, the business end of which consisted of two metal plates a foot apart with a big spark zapping back and forth between them. John proudly threw the switch on this puppy and my father-in-law, an engineer with a pacemaker, took one look at it and said "That's an impressive piece of equipment. I bet it puts out quite a magnetic field. I'M GETTING OUT OF HERE!" and took off at a dead run. John looked down doubtfully at his baby and asked "Should I put up a sign?"

If he does it without the suit, with his feet in a metal bucket filled with water, while strapped to an electric chair, holding bare wire soldered into a 220v line during a lightning storm while it's raining, then gets shot in the head, decapitated and set on fire and survives, ...

There certainly won't be the amps in those bolts to electrocute him--if they had that much power his suit wouldn't protect him from the sheer amount of energy being released around him. That's a faraday cage, not a NASA heat shield.

RogermcAllen: When you rub your socks on the carpet and shock a doorknob you are experiencing ~10k volts.


And I've experienced something in the proximity of 100kv. If the *BOLT* got you it hurt but the discharge itself you wouldn't even feel. (So long as the bolt came off something you were holding rather than your own skin you wouldn't know it other than seeing/hearing the bolt.)

Our teacher did a demo at around 300kv. He was limping for the rest of the class period because he made a mistake and stepped off his insulator after turning off the generator but he forgot to discharge himself.

But what is stopping us from using this machine higher up in the atmosphere to help repair the ozone layer?


1) It's a very inefficient way of producing ozone.

2) You can't effectively fix the ozone layer by adding ozone. The problem is that the ozone layer is dynamic--every time an ozone molecule stops a UV ray it's destroyed in the process. You get an oxygen molecule and a free oxygen atom. That free oxygen atom is *VERY* reactive and will quickly grab onto something. Usually that's another oxygen atom, creating a replacement ozone molecule. Occasionally it's another free oxygen atom, thus losing two ozone molecules from the cycle. Thus ozone is always being destroyed, new ozone is created when an oxygen molecule stops a very hot UV ray and splits into two free oxygen atoms.

The density of the ozone layer is the result of the balance between these two processes. What the "ozone destroying" chemicals do is provide a temporary storage site for a free oxygen atom, thus facilitating the destruction reaction and shifting the balance point.

We used both. We only had the Tesla Coil in the classroom once, but we had one. I am aware of the differences. This was in 6th grade, and the teacher was awesome. He also had the room filled with animals, including an alligator, a caiman, an anaconda(with an eating disorder), and a rattlesnake(For about a week, parents finally drew a line, I guess). We also studied electrical circuits by kicking the alligator out of his bathtub and hooking up a 12v battery to a model train transformer while we held hands and tried different amounts of current, while 2 of the kids would have their hands in the water. Fun year. I loved it.
