Electromagnetic Emission Art
mr_lithic writes "The artist Richard Box has used the electromagnetic field generated by overhead transmission cables to power 1300 fluorescent lightbulbs positioned underneath. Some pictures available.
Professor Denis Harshaw at Bristol University explains "There's an interactive element to all this, too, for those who go to the site itself. 'You affect the lights by your proximity', explains Richard Box, 'because you're a much better conductor than a glass tube. And there's sound as well as light - a crackling that corresponds to the flashing of the lights. There's a certain smell too, and your hair stands slightly on end.'"
Sounds cool and it is on until February 29th. Directons here."
Yeah, yeah chips in your hair. 2000.
A3 x 30. Taken in the studio this series of photographs depicts the artist fending off a swarm of silicon chips as if they were flying insects. The work deals with the effect, intended or not, of technology on the individual.

other than powering flourecent lights, electromagnetic waves can also kill your brain cells. This is one art exhibit that i dont wanna go visit.
Consensus is good, but informed dictatorship is better
The bulbs will be 'planted' across the site at the foot of an electricity pylon, and will pick up the waste emission from the overhead power line.
Not really. Lighting the bulbs most certainly reduces the power on the lines. The inductance of the power lines change because of the presence of the bulbs.
It's cool to see art and science actively collaborating. From the article:
Also, check out some of his other art. "A rotating, pulsating, elevating, sound and movement activated, life-size neon brain." Now that's just strange.
Enjoy your job, make lots of money, work within the law. Choose any two.
What? No GPS coordinates?
I toyed with ideas of free lighting (living close to high tension power lines)... seems a little pointless considering thousands of locals run jumper leads of the damn things anyway, with complete immunity from Meralco (Elec company)
Easier to jumper someone elses jumper leads anyway.

Technically, he scoops out energy from overhead lines. True, it's insignificant, but still he could be charged with theft. Of course, since it's art, I doubt anybody at the power company will say anything, but I wouldn't be surprised if they told him to take his art somewhere else.
A well know, similar "application", was demonstrated when wireless transmission technologies boomed in the 30s in Paris : the first antennas had been installed on top of the Eiffel tower and were putting out dozens of kilowatts. Some smart guy started selling battery-less flashlights under the tower, and a lot of gullible people bought them, amazed that they indeed created light magically without batteries. Little did they know the magic flashlights had a little coil inside that used the Eiffel tower antennas' HF power to light up the bulb, and therefore could only work under the tower. The flashlight seller was eventually caught and, far from being charged for scamming people, was charged for stealing TDF (French wireless authority) energy, which was apparently much worse.
But anyway, pretty cool art I say. The cows in the field nearby must have fun watching that every night.

Does arrangements like that actually "steal" any power from the powerlines, or would it be lost anyway if it was just air instead of neon tubes?
Will be headed out there with a camera ASAP. Perhaps local /.ers should arrange a meeting time and all go at once.

Is this theft? I ask because in the past, before the current overkill laws againts computer crime, crackers where charged with theft of electricy. Could he be charged?
Microwaving chocolate is a fun way to both measure the speed of light and get some edible artifacts of the patterns of the electromagnetic fields inside a microwave oven.

Growing up on a farm, I have learned of the negative effects "stray voltages" cause to farm animals.
This is often linked to the power return to the station. Everywhere, electrical service has everything connected in relation to ground, with any difference in the power balance of the phases of power taking a different path back to the source of the power, i.e. the ground itself, and potentially through anything in its path.
This "stray voltage" manifests itself when animals, with 4 bare hooves, paws, etc. touching the ground, detect small but irritating (to varying degrees) levels of current taking an alternate path back to the source. Animals have also been proven to have a higher sensitivity for detecting stray currents as well, compared to humans.
Often in cases, to the power companies defense, they will come out to do a check on the premises, and often do find a problem in the local, on-farm wiring, potentially causing the problem.
Unfortunately, in the cases of newer farms where all the wiring is new and up-to-code, a stray current is often traced to off-the-farm sources, for example, a newly-installed High-voltage Power Line.

The power company deserves to have their power stolen because they are too cheap to reconfigure their lines to reduce the electromagentic output:

I don't think so, because the magnetic field will be there if it's being used or not. It's just passive absorbtion of the company's waste.

It is more or less the same as plugging in a transformer on the powerline to power the lights.
The question is where we draw the line of theft.

I think the piece is more of an artistic rebuttal of the assertion that these high energy transmission lines are safe for humans and animals.
If you've got an EM field that is powerful enough to light up 1000 light bulbs, it seems intuitive that there is enough energy to cause harm to humans living at similar distances.
This is my sig.
Our physics teacher was using the Van der Graaf for an experiment (in fact, he was intending to measure the current it produced). Over the demonstrator's bench, a fluorescent tube was flickering. He got annoyed. He climbed on a stool to remove the offending fluorescent.
You can guess the rest. The remote end of the tube dropped towards the van der Graaf. About 10cm from the dome, there was a spark. The dome discharged through the tube, which flashed, the physicist, and the stool. Most impressive.
The tube survived falling on the bench. We learned several things from this:
Panurge has posted for the last time. Thanks for the positive moderations.
It is more or less the same as plugging in a transformer on the powerline to power the lights.
And so is simply standing anywhere within 100 feet of something like this. *Everything* within earshot causes a measurable increase in the resistance of power lines. It's not theft just because, in this case, the amount of power diverted is more than it otherwise would be.

That's good art :)
So all you need to do is stick a fluorescent light underneath?

I just can't buy this. Working with networks between buildings, ground differences are never more than a few volts, not even enough to tickle. The current carrying capacity is huge, though, leading to ground fault currents that might range into hundreds of amps fro less than a volt of potential difference. This is the reason that all network technologies involve electrical isolation from the network wiring.
More likely what your farm animals were responding to is the potential gradient established between the power lines and ground.
This reminds me of a lawsuit that OSU settled while I was a student there. They had some research going on in high voltage power distribution lines (~ 100 kvolts). The lines were run over farms outside of Columbus. Mounted about 200 feet above the ground, that gives a voltage gradient of about 500 volts per foot.
Well, it turns out that the owner of the property, a woman, was out working in the fields one day and squatted to take a piss. Urine, being the excellent conductor that it is, with about 500 volts potential across it (assuming that the source of urine was about 1 foot off the ground when she squatted) conducted electricity right through some sensitive parts!
She sued OSU for pain and suffering.
I mean, with the latest research on electromagnetical radiation in my mind, and this being a high-level electromagnetical field, I certainly do not want to take the risk to get back from that site with a rotten brain...
Slashdot: stuff for news, nerds that matter, matter for news, stuff that nerd
I also remember one of my high school teachers talking about how he used to work for hydro and look for this sort of thing while flying in a helicopter and inspecting power lines.
Really it shouldn't be that hard to find this sort of thing. You can just use a time domain reflectometer, and power companies have these for finding cable faults.
Breathing: you're taking oxygen that clearly was produced on a farm somewhere or maybe in the Amazon.
Tinfoil hats: these devices intercept electromagnetic waves and cause transmission losses.
Heat pumps: you didn't really think you could take all that "free" heat out of the air, did you?
"I assumed blithely that there were no elves out there in the darkness"
We don't see any of you idiots building power plants for yourselves.
Come one now, this has already been throughly answered. Why was he modded intereseting?
Think about it this way: If you have your car running at 3000rpm in neutral, does it use the same amount of fuel as the same car pulling a boat up a hill running at 3000rpm?
Of course not!
When radio transmitters transmit, they do see a 'load' imposed by the air and surrounding objects. A misconfigured antenna can burn out a transmitter essentially because it loads the radio too much (well it creates SWR, etc).
A transmitter without an antenna cannot impart its full power into the air, just as there is no 'wasted' energy by having an unconnected battery. You can think of antennas as ways to connect something to the air (bad analogy though).
Well, powerlines are pretty simliar to a long wire antenna....
The lights in the article do place an extra load on the powerlines. Well, the neat thing about electricity is that electric current, electric fields, and magnetic fields are all related (Mawell's Law, etc).
You don't actually need wires to carry electricity (its just a heck of a lot easier in practice).
It'll be okay. Just reach around behind your ear and hit the degauss button.

I also forgot to mention that animals can be sensitive to ground differentials as small as 0.5 to 1 volt depending upon conditions.

I was grading papers for a college writing class the other day when I came across a paper that a student had written about measuring the speed of light using the microwaving chacolate method. At first I thought he was just making shit up, but then I looked it up on the interweb, and lo and behold, he hadn't made it up.
Granted, he had copied his paper almost word for word from the interweb and I failed him for that, which just goes to show that it's dangerous to write papers that interest the graders.
Mod my comments down. It'll be fun.
I am not allowed to use all the electromagnetic waves that pass thru my property.
This issue is a bit more complicated than you think.
Would headphones (earphones) cause any "death in braincells" if worn constantly? Since they have magnets in them.. just wondered if any of it pertains ?

I have some really bad news for you: the Sun has a giant-ass magnetic field, and the Earth intersects those field lines as it orbits around the Sun.... Guess what? There have been big ground currents in the Earth since a long time!
"Inverse Square Law?"
During a visit to a power station, we were shown the
12 Mega Watt output cables. Asides from the crackling noise due to a light drizzle falling on the cables, there were other effects too.
Having stood under the cables for a couple of minutes, I felt no adverse effect... until I started to walk away. That's when I started to get a headache...
My hyperlinks aren't worth the paper they're printed on.
It's true. Apply the dielectic materialism argument.
Technology is all bad. (illogical exclusive negative )
Technology is all good. (illogical exclusive positive)
Solution: Technology is both good and bad.
In fact, since technology is generally assumed to be created by man, the argument surely must be redirected towards man. For after all is said and done, it is HOW man uses technology that determines whether the outcome is good or bad.
My hyperlinks aren't worth the paper they're printed on.

Couldn't help but notice the photo with the floating brains. I didn't realize the Brain Spawn were here already (although that would explain some things going on in the world). I'm not sure we can wait 1000 years for Fry to wipe them out.
"Kittens give Morbo gas!"
To sum up the following; 60 htz x Earth's Magnetic field = Lithium ion (which exists naturally in human biology) becomes direcionally excited so that its impact upon brain chemistry is increased to achieve narcotic effect. (Lithium is the base of many anti-depressant drugs.)
Is there a website with information on how I can do this myself? Due the the legalities, I wouldn't exploit this, I just want to see it in action for a few minutes. I have high voltage power lines running through my backyard, so I have easy access.

I can say the same thing about DirecTV, I'll stop stealing their signals as soon as they stop beaming at my property.
To be honest, I don't see any way a sane person could disagree with you. You're sending me the signals, I'm performing some DSP on them and connecting them to my TV. Fuck you if our business model sucks. You have no "right" to profit by beaming high-powered waves through my house.
My other car is first.
I agree, but the question is will it stand up in court. If DirecTV doesn't want me to view their signals, they need to stop sending them to me.
It's not just on farms, either. Did you hear about this ("Teachers College Student Dies in Freak Accident," Columbia Daily Spectator)?
Apparently almost 300 objects carrying stray current--metal grates, service boxes, even lamp poles--have been identified around the city since this article was written. IIRC, there was even 120 volts found to be running through a lamppost one block from Times Square. This according to the NYT.
Just another thing to consider as you walk to work tomorrow...

And if parents don't want you murdering their children and eating them for Halloween dinner, I suppose they need to stop sending their little ghosts and princesses up to your front door? Sorry, I don't buy it.
Yeah, but I'm not eating the DirecTV CEO. Apples and oragnes, and you know it.
That wasn't my point... Your argument seems to be "if it's on my property, I should be able to do what I want with it." I was trying to point out that that position, while attractive, is neither logical nor valid. Taking satellite TV without paying for it, or for that matter power from the electric utility, ultimately hurts everybody else; that's why we have laws making it illegal.
:-) So I apologize for the (facile) analogy I was making in my earlier post.
From a theoretical standpoint, the costs of losing trust are very high. Some would say that's why we have laws at all.
Regarding apples and oranges, I have to admit I hate analogies as much as anyone.

Yes, but they aren't high amperage, just high voltage (and we don't know any better because we're constantly grounded, so we can't notice it...)
I agree, that's why I said it will never hold up in court. I just wish there was a way to tell DirecTV and others to keep off my property. (I don't steal TV, I don't even have one to watch)
Well, you could always build one of these over your roof. :-)
Why is slashdot all british central? I'm an american you insensitive clod. there are places outside britin.
Couldn't they then tell you to stop aiming your antenna at their satellite?
It's my antenna on my property, as such I can do with it what I please. Conversly, I should be able to tell them to get their satelitte out of my way, it's blocking my view.
TOO MANY WORDS. mod article excessivelyblabla.
You pathetic moron. That was only two pages from a paperback.
Were you one of those losers in school who looked at me when I cracked a book and said in awe, "You READ?"
The fact that you cannot digest more than a sound-bite is evidence of how far gone you are. I am certainly not going to play along with the TV version of reality. Information and knowledge are valuable, and the above had it all; claim, easy to follow explanation as well as references. It's an important topic well worth exploring, and difficult to present for your worm-like benefit. If you found it had TOO MANY WORDS, then you deserve exactly what will happen to you.
So I'm sorry I overwhelmed you, dipshit. I think I hear your Cell Phone ringing. Go stick it next to your brain and talk in idiot sound bites for a while. That should calm your nerves and make it all seem okay again.
