At 10kV, a random stick would be all it takes to start an arc. He knows what he’s doing.
True, True… Hay who thought it was safe to run 10,000V Wire through a flammable overgrown jungle?
The people who wouldn’t cry about a dino BBQ scenario.
I’m genuinelly curious were you got that from.
I actually went and checked the minimum air gap to avoid arcing at 10,000V at standard sea level air pressure and it’s actually measured in millimeters.
Further, is the voltage differential there between parallel conducting lines or is it between the lines and the ground?
I’m really having trouble seing how a dry stick would cause arcing between two of those lines short of bringing them nearer than 4 mm in the first case, much less between one of the lines and the ground in the second case if its being held at chest level.
PS: Mind you, it does make sense with a stick which is not dry - since the water in it makes it conductive - but then the guy himself would be part of the conductive circuit, which kinda defeats the point of using a stick.
Yeah that’s people with PhDs in my experience
Yeah, in this case it’s so high voltage that the resistance of the dry stick wont mean as much.
Clearly his PhD is not in electrical engineering or biology
It’s actually a PhD in trombone. Someone misheard it one time, and nobody has ever thought to follow up.
“Oh, Alan? Yeah, he has a doctorate in bones or something.”
I invite you to touch an electric fence with a stick then.
i’m not touching your stick man, gross!
You’re describing my pre-internet childhood.
(It wasn’t a 10k volt t-rex fence though)
Well, I have an EE Degree specialized in Digital Systems - pretty much the opposite side of Electronic Engineering from the High Power side - and I would be almost as clueless as that guy when it comes to testing a 10,000V fence for power.
On the other hand I do know a lot of interesting things about CPU design ;)
He is already standing too close and that stick would arc with that many volts flowing through it. The most likely outcome in reality if it had been energized. The arc would have jumped from the stick to him and no more New Zealand guy.
With only 10’000 V? That’s a common Livestock Guardian*. Reaches at most 1 cm.
* though it probably has enough ampere to kill a cow
Now if he’d just tossed the stick at it longwise so that it touched several wires at the same time, it might get a result. I’m personally not sure how much a reaction you’d get out of dry wood with 10,000 volts. Stripping the bark off of green stick with definitely be better, or a wet stick. Although if electricity arced through the stick at least it probably wouldn’t kill him because of the amount of resistance that stick has.
You ever saw a electric fence at a high security installation? I just texted a guard at nearby prison and he said theirs are 5000 volts. He said when its humid they tingle when you get a few feet away. He also says they will kill you dead. He goes on to say its why they have another fence as a barrier to prevent people who don’t respect them from killing themselves. I know the ones at a nuke were marked lethal and would kill birds from time to time. They were just marked high voltage but the plant guys told us they were very high voltage at a higher frequency.
Yep, Volt makes sparks, Ampere makes hurt.
Tesla coils usuallly have around 100k Volt and don’t kill you. Tasers 20k to 40k i think? The high voltage in guardians is mostly so that it connects.
He probably wanted to prevent significant arcing by using a higher impedance test apparatus due to the high voltage.
Why people gotta hate on a movie three decades old that remains perfect?
Gotta meme to keep it alive
Hey it’s a “It’s a UNIX system” movie, isn’t it?
I know that!
not a phd in physics huh
At least he’s smart enough to know you Don’t whizz on the electric fence
Mythbusters did it.
Even throwing a metal pipe against it won’t do anything. Electric fences have one electrode in the ground, and that’s how your body makes the circuit. If they had run and jumped onto the fence, then jumped off on the other side they would have been fine with the fences still active.
Source: I’ve set up an electric fence and been shocked multiple times, once through my head.
Yet Tim gets shocked when hanging on the fence when it turns on while he’s climbing down. I trust movie science far more than your acquired knowledge. Your ignorance is probably what’s holding you back from full blown deity.
Ever seen birds standing on powerlines?
You’re assuming the dinosaur fence operates on the same principal as a regular livestock electric fence. I put it to you that the Dino enclosures use alternating positive and negative stringer wires, where touching one won’t do anything, but touching two will make a short circuit.
That would make a lot of sense, but as we can see the stringers are connected together, meaning they’d just short out if they were alternate polarities. To me this indicates that it’s like a standard livestock fence, with an electrode in the ground somewhere and the circuit completing through the animal.
However, considering my 16’x48’ pig enclosure required a three-foot rod to be grounded, a system large enough for a sauropod would need a lot of grounding. Considering this, the fact that they used a circuit-through-animal design indicates it probably wasn’t the best way to do it.
Spared no expense…
Maybe the stringer spacers are polymer though. Like those separation bars you see on residential power lines
Maybe they’re polymer but they look pretty metallic and there’s an awful lot of them. Plus if the stringers are under enough tension for a full grown man to climb them they wouldn’t need separators.
I always thought that was a piece of fence.
Idiot didnt know the MAD was 2’2", SMDH.
Yep. Very domain specific knowledge but couldn’t pour piss outta a boot with the instructions on the heel.
The first film paints a different picture.
The whole point of his story in that film was his growth and development, started saying “kids smell” and ended holding two of them safe.
He was the one throughout who kept his head, stayed competent in the face of fear and dealing with chaos.
