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.

I was there for the opening. It was very underwhelming. The current of anticipation that was generating through the audience burned out in about two minutes.

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.

Puns? I'll just be happy if he gets zapped and leaves us alone.

Hohum. Been done by much better.

It is basically a glorified taser.

His biggest problems will be boredom, sleep deprivation, hunger/thirst, and having to pee.

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

Tesla would do demos sans faraday suit. The super-high frequencies he would work with caused the current to conduct across the surface of the skin with little resistance.

IT'S A FAAAAKE.

That particular photograph is a double exposure.

I think this would be better attempted by someone employed by India's underfunded and out of date railroad system. if you're facing that much electricity, it's probably best if you're a poor conductor.

So, you mean, what Arc Attack has been doing for years?
 
2012-10-06 10:30:37 PM  
Let's give credit where credit's due: Arc Attack is the team behind the Tesla coils. And what they do with Tesla coils is awesome. In addition to their own team member decked out in chainmail, a few lucky people from the audience are picked out each show to jump around in the Faraday cage.

All this attention might go to his head.
Lets just hope he stays grounded.

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.

After three days, he might have trouble with the O3 and NO2 produced by the arc.

Maybe repeate the Ben Franklin story. That would be exciting. Definitely not Edison's 'let's kill an elephant with AC' hype. The old DC trolley stories are kinda funny, though. "Here's my stop... UggghhkaaGzzzzhh!"

I am not a smart man, but I recall seeing a headline lately that stated this stunt will build up ozone in the vicinity, which I guess is a bad thing when it's too close to the ground. But what is stopping us from using this machine higher up in the atmosphere to help repair the ozone layer?

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.

dletter: So, you mean, what Arc Attack has been doing for years?


Yep. Only difference is that Blaine is doing it for an extended period. Arc Attack would still be about a million times better to watch...
