Actaully, it would be mostly rather trival. However, pulling the current required by your house wouldn't be though. The whole point of using AC is that power doesn't dissappiate over long distances, while it does with DC. Depending on your house, this could or couldn't be a problem.
Not true. actually 'power disipation' aka losses is less in a DC system because you dont have to overcome the inductance of the line. You still will get voltage drop across an AC line unless you do something to change the phase angle across the line(about 3 courses worth of material to describe all the methods). This is what occurs in Distribution and Transmission, but does not occur in houses.
I'm not sure exactly if what your saying about CD's is correct, do you have an article link I could read maybe??
I dont have alot of time right now, but I would suggest the ACM and look for papers on the one time pad, or ask any professor that is into encryption.
I just know it doesn't sound sensical.
It doesnt at first, but ifyou think about it, it does. lets just say you use a ROT like encryption technique(where you change the charater by an offest to get some obfiscation) However, if you change the offest randomly every time, you never know what the next character will be, even if you know what this character is. Period. You can decode it into whatever you want, but not necessarily what it really says;->. This assumes, like I said before, that it is random, as it becomes less random, you can begin to guess what the next character is, and slowly work to a probable soltion.
If you distribute the pad with the CD then there's no point in encrypting it in the first place.
No, really, there is. until commanders in the US can predict with perfect clarity what will happen in the field, you will always need a high speed, secure communication method. Hand carrying the Pads is not that big of a deal compared to getting things like food and gas to the frontline
For things like subs with ULF communciations this is no problem really. Give every sub a different pad, so that compromising one sub doesnt affect the others. You only use is for things like firing orders, and movment information. with things like ULF you already have such a slow data rate, that you dont want to send more than a few bytes, and you can fit a lot of bytes on a CD's.
because ULF can be detected pretty much everywhere, you need something that is basically uncrackable.
Its not like the someone is going to be download porn through an encrypted media, you dont really need to send that much information.
Not True. Given True Randomness(TM), a one time pad is impervious to even brute force attack. This is why the US military uses it for high secuirity communication. CD's(DVD's now?) are generated through some method, i think by listening to noise in the sky or something bizzare, disributed with the pads on them, and if they are so much as throught to be compromised, the whole batch is destoyed(interestingly enough, one of the prefered methods, if a CD shredder is not availible, is to use a microwave. They even have a procedure written up about how to do it properly;->) and new pads are distributed. However, if true randomnes is not assured, you can use statistical measures to force portions of the messages, apparently.
Their are a number of valid reasons for that. Primarily, your equipment wouldnt last long trying to feed all of your neighbors.;-> And if-when you try to synchrounize, you need to make sure that you have no phase angle difference in the voltage, or you can get huge (and I mean huge!) ocsilations of current flow. But, I would think that with responable protection at your house, you could island yourself from the network during an outage, and then be forced to de-energized before you reconnect.
PS....most of the grid tie-in stuff is mandated by FERC or NERC, sometimes by the local cordinating councle like the WECC. you might try to find out what the utility is required to provide as far as service and connections.
I'm taking an AC drives course this semester, and the book is written by my several of my professors major professor during their grad days. Its a Decent book, content wise, however, its 167 dollars (167!) and one of my friends already had a page rip out! On the other hand my symetrical componets book has been out of regular print for a while so the publisher just let them copy it. 20 bucks! woo!
I think it would be alot harder than that, when you change key's on a guitar, you dont tune all the strings the same all the time. You can drop tune certain strings etc. It would be pretty hard to pick out just a specific string, remodulate it, then change everything back.
Not exactly true for some people. some have circulator problems (women particularly are suceptable) My wife in particular. On even the sunniest days on the hill (snowboarding) her feet get cold despite the fact that we are both sweating from the sun under our jackets. And two, gloves dont necessarily hinder your hands. apparently alot of pit crews wear them and those people have to do alot of stuff fast.
Air is a fairly good insulator, so it takes a while for your body to radiate 1 Joule of energy to heat up the air. water on the other hand is not a good insulator and will accumulate energy faster, and release it faster, one of the reasons why you dont want to fall in the water in the Gulf of alaska, even if it's the middel of the summer. so as long as whatever is in the glove can transfer heat faster than your fingers can radiate away you've got it beat. Add a small amount of insulation and your ahead of the game.
The problem with a wire is that it will radiate some heat while the energy is traveling from one end to the other. now if that material can flow over your hands relativley quickley it will have less time to lose it's inherent energy. Basically you might be able to see the same results by taking a quarter, and stiking it under your armpit, and then moving it to your hand once its warm. Now take another quarter and stick it in your armpit. Swap this back and forth as the one in your hand cools down. This will transfer more heat than if you stick a wire in your armpit and another in your hand. and if you make it passive, ie using convection currents and all of that, you greatley increase reliabity and usability. talk about a great survival tool.
You have to realize that there are many places that already have a system for transmitting data over powerlines? it's called Power Line Keying, and it's used for differential protection of transmission lines. and one problem is the fact that powerelectronic loads/sources both provide sources of high frequency harmonics, and have been known to burn out the transmitter and reciver of the PLK.
Not quite what you are talking about, but NxtPhase makes optical voltage and current transformers for measurment of high voltages lines using the Faraday effect. Quite cool, a grad student here at Uof I has told me he can make one for a couple of hundered;->
Uh.....In war you usually pick targets that are important to the enemy. (btw they dropped leaflets over both tagets for several weeks befor the bombing warning of the devestation that was about to come.....the people didnt belive them) and YES they really did need to use two, Japan did not surrender after the first one, the emporer was afraid of being overthrown by many of the "warrior class"
Biogas I belive would be a good use of the 'pigshit natural resource';-> infact I think it should be a requirement to setup co-gen similar to this. Infact I would be willing to federally subsidize the industry to do it
I am very curious, my biggest problems with public schools is things like "no child left behind act" etc. where basically I get screwed if I am not requring high attention by being a fuck up, or by not being a genius like some of my friends. I figure The 5% at the top(due to political pressures and the desire to produce very good students) and the 5% at the bottom (due to law and the desire to help out the less fortunate) get 50% of the time and money. oh well
Thats because they can choose who to accept and teach. public schools cant, therfore this logic is flawed. If public schools only had students that were motivated, or had parents that motivate them (like most private schools require) than we could compare private to public schools.
yes, true in the strictest sense, however a gas or desiel must use a clutch or transmision with significant losses because they have zero torq at zero speed. A variavble freqeuncy induction drive (like this) can generate all that torque at start, so you can actually apply more force, even tought the peak is still the same level.
no, actually, DC transmits better over long distances, you dont get reactive losses, like in AC transmission. See Hydro Qubec and the Pacific Intertie. You just get voltage drops, which is hard to compensate for without a DC transformer, so you use a DC/DC converter at each location.
Basically the break even point for efficeny is about 200 miles for general above ground, and like 20-50 miles for underwaer or underground.
Sorry, My wife is a canadian and all her friends back home make this same statment, then I see a "I am Canadian" Commercial or a Hockey night commercial, or any number of things. Canada also has an inferiroty complex, or something when it comes to the states. (Dont ask me why, it shouldnt, I think they are just tired of being ignored by us, and called americans by others;->) As far as I can tell, alot of canada defines it self as "Not American"
Uhh, this has little to do with regulating power flow, as much as it has to do with physcis, you see a generator doesnt make energy, it converts it from mechanincal to electrical. That mechanical source has inertia....now your powergrid has inertia, if your load suddenly drops by 20% you can just suddenly change your energy into the system, you speed up the system as a whole. This is a bad thing, so you now have to disconnect your generators to protect them, the transfromers and the loads. suddenly your dark.
Yes, sort of. 59.9 is sorta ok, 59.8 and you have major problems, by adjusting variation when referring to frequency you mean a couple of cycles over a whole day. And yes they do try to do it in real time, it just because very very tough if your grid spans several time zones (a ver long high load time then..)
Because proprietary is the wrong word, and you sound like an idiot calling a proprietary product an alternative to using a proprietary product. its like...hey I hate SUV's that's why I bought a Jeep Cherokee.
I have ran into one to many Park rangers whos ideas on nature and biology border on that of mystesism and raving lunacy. I once had one ranger tell me a story:
A guy is fishing fly fishin legaly(yellowstone or something). He gets his catch and starts walking back to his rig, and a bear steps out of the trail a few feet from him, and he stops, The bear starts towards him. He steps back slowly (bear saftey). The bear walks over and sniffs the fish. The guy drops the fish and backs away. The Bear proceads to eat the fish, and the guy gets away.
Moral of the story from Park ranger? This is bad it makes the human food connection. What would she have had him do? Get mauled? That would have sure made the human food connection! I live around bears (SE Alaska).
Or look at the fact that deer are overpopulated in many areas now, or that Buffalo in Yellowstone are causing huge disease problems all over the country due to over grazing and over population in given areas.
Glacier bay alaska allows very few boats in per day, because they "Scare the Wales" Bullshit. Utter Bullshit. I have personally been playfully chased by a whales, porposes in several boats, not to mention their intrest in it.
I think we need decent land managment, the Parks service is not it.
