Well, I know people who work in the power generation and distribution business in the midwest U.S. Arcs cause resets, too many resets, and the circuits are taken out and it takes serious human intervention to bring them back in. This costs time and money. I find it shocking that there are utilities that scrimp on a few links of insulator to lengthen the path to ground through the dust buildup so that they don't have periodic fault to ground or fault to phase events. Those can get expensive fast. Once again, if any area experiences more than a few of these events and the plant engineers don't schedule a fix on the next maint outage they should be fired. Dumping an 18.8 kV feeder sucks. Dumping a 46 kV feeder is a major pain. Dumping a 230kV trans line will inconvenience lots of customers and will cost a fortune to cycle and bring back up. A utility doesn't let that happen more than about two times before heads roll. About the only thing that would piss off the management worse would be doing something really stupid and getting a 600MW alternator kicked out of the grid and having to spin it back up and sync it back in.
Yeah. So. That's why the insulators on the big lines are several feet long and the work poles for handling the high end lines are over 10 feet long fiberglass monstrosities. The dust isn't a significantly better conductor than the air, glass, and ceramics they are settling on. If the utilities in Australia are so incompetant that they can't factor the capacitance and resistance of dust buildup on transmission towers, the engineers need to lose their jobs. It's not like they can come back and say "We didn't forsee the dry season would cause dust accumulations." It happens every fucking year.
Take basic high school chem and physics classes then look at your statement again. If it wasn't for the fact that buried underground there isn't enough oxygen to combust with the gas if there was an ignition source(spark), the arc should just conduct through the gas line for a short distance and dissipate to ground. A spark striking a gas conduit won't somehow mystically break the conduit and cause the natural gas to vent to the atmosphere through several feet of soil.
Hell, some places they run power and fibre down old decomissioned gas conduit. It's cheaper to lay new gas conduit rather than recertify after a certain time. The old conduit sometimes gets reused to carry other utilities. That said there is a significant transmission loss, both resistive and capacitive, to running power through underground conduit versus overhead lines. Over the long run this transmission loss is much more expensive than the costs of trenching in power underground.
Last I heard most of the material that makes up dust is a decent insulator. I have seen issues with enviromental items (animals) causing shorts. Nothing quite like a bird of prey coming in to roost on an HT tower and shorting two lines. The sparks are pretty impressive for the fraction of a second before the breakers kick the circuit.
Its not going to cut down the number of patent applications, all its going to do is cause more appeals and more work for the USPTO.
Good. Then maybe congress will get off their lazy asses and pass some patent laws that can be applied in a sane way. I don't expect that to happen though. If they did actually do an overhaul of the patent process it would be to make it easier for corporationas and harder for individuals to get patents as well as extend the terms to rediculous lengths like copyright.
Ok, young man. You just take that logic and go to your room. I don't want to hear any more of that public domain is a good thing talk. Who do you think you are siding with those viscious, heartless monsters who wrote the constitution rather than the warm, loving coprporations who are just trying to scrape out a meager living making a few hundred million with the sweat of their lawyers brows.
I never said Liam would actually read Slashdot. I'm not sure if Liam reads at all, but he has gotten in a few fights with people who didn't agree with him that Oasis is the greatest rock band EVER! Maybe Noel will tell him, or maybe one of the tech geek roadies will tell him, then one day , Liam will blind side you. He'll pin you to the ground and sissie slap you say "Oasis is the coolest." and "Liam is a god." You'll see. He's like that.
He learned long ago, but he refuses to play the MPAA game. As long as the MPAA can buy legislation they will refuse to play Jobs game. The RIAA is coming around slowly by the looks of it, but they still occasionaly whine about wanting tiered pricing even though they are doing well with the existing pricing model.
Dude, read Fox News and CNN. They have killed the irregular tense verbs. About the only one they still use is ran, otherwise they just put "ed" on the end of every verb. English, at least in the U.S., is simply convention. After a while even the pedants give up the fight and the new "rules" take over.
Oh, I report them also, but I still get really tired of logging on, seeing the mail icon and finding out it's the generic "Want cheap gold?!?!?! Visit http://www.wesuckreallywedo.com/pharmingasshats"
You sir, or madame, are full of shit. I know two people who insist on a literal and flawless interpretation of the bible. If it is in their KJV bible it is true with the translation to english fixing several lies in the vulgate because God inspired the translators. A very nice couple to be around as long as you don't bring up religion.
The problem is he built the recreational facility on the existing waste water plants property, so it sounds like he's a speculation developer rather than an engineer. "Hell, this place will be so much fun they will come no matter how bad it smells."
Well, this is Slashdot. The editors can put the stories in whatever catagories they damn well please. If you dont like Slashdots actions, dont use them anymore. This isnt a holy violation of your rights or anything else. HTH.:)
To lower some of the stress of the controllers a few years ago they started allowing flight crews a good bit of leniency in flight path and altitude, and an expansion on the basic collision avoidance rules (Right of Way stuff). According to some people I know who are associated with ATC it made things less stressful, but that is very relative. One of the ATC people I know said that 25 years ago when you had a near collision the controller got a pack of cigarettes, a cup of cofee, and 30 minutes in the tower break room, then back to shuffling sky buses.

You know, there are easier ways to commit suicide than taunting Liam Gallagher in an online forum.
Well then, pick it up cheaper elsewhere, and buy your other movies for $9.99 at iTunes rather than $15.99 whereever else.

Nah. He's not an alt. He plays like a noob who bought an account.
You do know that Greenspan retired a while back and a Mr. Bernacke(sp) is running the Fed now?
I just wish I would stop getting solicitations from gold farmers in my in-game inbox.
Aw, dude. You're no pun. :(
I will have to remember that. Now I'm off to clean the Mountain Dew off my monitor.
Viri is the plural of vir, which means man. Oh, my god, men are made up of multiple virus. This explains everything.

Only if he didn't know latin. In latin there is no plural form for virus. It's simply virus no matter how many plant toxins you are speaking about.
