I'll give you that they aren't smokey and slow. But I'm sorry, youa re dead wrong: a Diesel Engine is WAY louder than a gas engine. Why?
Can you say 18:1 compression?
Compression has nothing to do with it. I can put my ear by my idling '02 Jetta TDI, and it's truly quiet, and I have very good ears. The exhaust noise is, in fact, much quieter than most gasoline powered cars with compression ratios in the 9-10:1 range. The exhaust amounts to a slight puff-puff-puff, and it's not much worse whilst going down the highway. My computer is markedly louder than this car idling, if you listen at the tailpipe. It's the quietest car I've ever owned.
The major source of the noise in not in the injectors, it's not in the pump, it's not in the exhaust, it's nowhere else but in the detonation of the fuel/air mix, right in the top of the cylinder... This is what gives diesel engines their distinctive clacking noise. Newer Common Rail diesels will significantly reduce the effect of this by starting the combustion stroke with a tiny squirt of fuel a couple milliseconds before the full charge is delivered.
The Audi R10, one of the latest race cars to use a diesel engine, is quieter than the cars its competes against in the LMP1 class, thanks to the common rail system, and thanks to its turbochargers (which have a significant effect on exhaust noise) and yet its compression ratio is obviously much higher.
Not really, the action itself already excludes the possibility that he is a G-man with a conscience. If he was he'd respect the limits imposed on him by the law which he is supposed to uphold. You cannot serve the law by breaking it.
First off, it's doubtful anyone has a rheostat dimmer any longer. Those went out a long, long, long time ago, and were brutally inefficient anyway. You might have found such a beast installed in a theater built no later than the 60's. Any modern dimmer is triac (for cheap dimmers often built into lamps) or SCR based (for more expensive units), and the pot controls how the circuitry changes the waveform.
Secondly, they make dimmable CFLs. Problem solved.
I was listening to a religious program about purity when there was an add for an "adult only" vacation.
Somewhat disappointing I must say
You're lucky the ad wasn't for a Mediterranean cruise featuring male prostitutes, methamphetamine, and only the most supple choir/altar boys. After all, we do understand the religious demographic very well, notwithstanding the image they'd rather be associated with.
Even more abuse of technical terminology. A capacitor stores energy which can later be extracted and used elsewhere in a circuit. I don't see any description of a reversible cycle refrigeration system which would allow extraction of the 'thermal energy' stored.
From the context of my wording, any half-brained nincompoop should easily understand that I wasn't referring to an electrical device, and that the function of said devices (those devices being a cold storage unit, and a capacitor) are close enough to be considered truly analogous to anyone but a rabid and confused pedant. So, which is it?
Furthermore, you need to learn to read and/or comprehend. The ZD article says this: "The idea seems simple. Say you lowered the temperature of all large coldstores in Europe by just 1C during the night when electricity demand is low, then let it rise 1C by switching them off during the day when demand is at peak. The net effect would be that the warehouses would act as batteries -- potentially storing 50,000 megawatt-hours of energy -- and the food wouldn't melt., the nature.com article says the same thing, and the PDF linked *from the site of the project* says this, "To use a refrigerated warehouse as a giant battery for wind energy. To store all electricity produced during nighttime by windmills all over Europe, and to release this energy again during the peak electricity demand hours in daytime. That is, in short, what the EU "Night Wind" project wants to demonstrate." No less than this, all of the articles outline this idea on the graphs on those articles, incidentally because they're all the same. You couldn't miss this little tidbit unless you tried!
Does that satisfy you? So, they doesn't describe the workings of the system in intricate detail, it's a freaking press report/release, it's not supposed to. They do, however, make it clear they want to test a reversible system! Regarding your last paragraph: My guess is that they will not have a single refrigeration system that's going to produce cold one minute, then turn the other way, at a moment's notice. They're probably proposing a separate engine?
This is quite true. It is possible to store energy by creating a temperature difference and later, to extract it to do work elsewhere. However, the original article doesn't describe such technology. They are simply rescheduling their energy consumption to off peak periods in order to reduce it during peak demand times.
Well, I dunno if you and I read the same articles (and PDF document), but I definitely got the feeling out of both articles (and the PDF document) that they were proposing to create a thermal energy capacitor of sorts (no less than a network of them across Europe), to even out the availability of renewable energy sources, and to allow convenient output of that energy during peak hours, which often happens when such resources aren't putting out 100%.
Quoth the second article "Being a refrigeration expert, I realized the possibilities of using refrigerated warehouses as thermal energy storage and therefore as electrical energy storage," says Van der Sluis. The capacity of Europe's coldstores alone could handle more than twice the projected output of wind power in the European Union in 2010, he calculates.
Of course, there are two hurdles. These places are probably going to need lots and lots more insulation. Also, the differential probably isn't large enough to make this sort of storage very efficient. However, if they calculated that it will work, I think it's worth a go.
I might have taken physics a long time ago, but we learned that you make things colder by removing energy. So there can be no such thing as cold energy storage.
If you took thermodynamics you would learn that energy can be extracted from a system with differing temperatures. By pumping the heat out of the cold storage (and the food), you use work. The heat is moved from the inside to the outside. It's like pushing a ball up a hill. Now that it's on the top of the hill you can let it go and use the potential energy you put into it for whatever purpose. It's all about the first law of thermodynamics, which is basically just the law of conservation of energy.
There are engines that directly extract work from such systems. It's all pretty basic stuff. Getting it to work, however... Not so basic. I'll be impressed if they get it to go.
I don't know why everyone is getting down on you, but this is exactly what some power generating systems do. Look up "combined cycle power plant", basically what you propose is a power plant with two or more thermodynamic cycles... They're already out there.
Indeed... This just makes me want to unload the contents of my stomach upon someone. Any of you scientology fags care to volunteer to be the victim of my projectile vomit? Look at it this way, you could probably charge me with a hate crime, you could send me, a hateful heretic, to prison. That's got to make being covered in a half digested Village Inn Santa Fe Chicken Skillet worth it.
But they don't stop to think: "Hey, someone liked this part of this program enough to go through the effort of editing our clip, and uploading the clip to let other people watch. His time wasn't free, and he deemed that our product had enough value that other people should also enjoy it. We aught to let those other people watch it, so they will be more inclined to watch our show live when they see it on their cable box, and those eyes will see our ads, too!"
I mean, it's one thing to upload a whole program to these sites, those videos should, and undoubtedly will be taken down as they are uploaded... A smart company, however, would KILL for advertising like this. It's free, it takes no effort beyond the initial investment whatsoever, and it's highly effective because it targets a niche market which is proven to enjoy your product. If anything, Viacom's stockholders aught to be lynching the management for not figuring out a way to make this phenomenon *more effective*, to establish more mindshare, to draw in more viewers, to up the ratings, and to make more money in the end!
I never reversed myself. I just don't see how a wikipedia article pointing to a BBC article from from five years ago is good proof of what's happening today, do you? For a while, china blocked most if not all western search sites. Google and Yahoo (and AOL, and MSN) got on the PRC's good graces by agreeing to work with the government to block objectionable content, so they could have access to the gigantic market share, back in those days... But those days are NOT today.
You know what would I would consider proof? A person in China trying to visit search engines of languages foreign to China, and being blocked or redirected to a Chinese site. Is that too problematic?
All the recent anecdotal evidence (about the last two years) I've seen is that these foreign search sites are readily accessible, but upon searching for objectionable words your connection is reset for 30 minutes, or the firewall filters out sensitive URLs, and/or filters packets with sensitive information, or the firewall simply filters out results provided by search engines.
How about this for contrary evidence? Note this: they say google.cn is self-censored, and results from google.com will be censored by the firewall, which would seem to indicate to a logical person that the site is still accessible, if limited by the firewall.
Also forgot to mention that elgooG was incapable of passing Chinese characters (or indeed anything with two byte encoding) to Google, so it was useless to most Chinese citizens, by default. Plus, how long do you think the government was going to let that happen?
Yeah, look at the article the wiki links to. That was from around 2002. elgooG apparently no longer works, and the Great Firewall is bound to block lots of things that would normally show up in google searches, making the whole effort mostly useless anyway.
No, it's the result of China's firewall redirecting to google.cn
No, it's the fact that google uses geocoding to figure out what country you're in, and they redirect you to the site you're most likely to find useful. I've never been behind the great firewall, but I'm quite confident anyone can access a google site for any locale.
The result is that it's effectively impossible to bring up the US version in mainland China; most users will only ever see the "cn" version.
Huh? Is the result of most Chinese users only seeing the.cn version of the site a result of some government or corporate action, or is it simply because most Chinese speak and read only Chinese? Oh, most United States citizens access only the.com, English, North American version of google. Since they effectively never visit google.de or google.co.uk, or google.fr, or google.co.kr, or even lowly google.cn, it must mean that it's effectively impossible to go there, so there must be some sort of gover-commercial conspiracy going on..
You, uh, also have to know how to operate a bridgeport upright mill.
Last I checked, bridgeport operating was a specialized skill that actually pays pretty well in my area (Metro Detroit) because it requires some training and experience to actually know what you're doing.
First of all, the best tool to do this job is called a horizontal mill, not an "upright mill", whatever that is. A key cutting machine, the tool the locksmith uses to duplicate keys, is basically a specialized version of a horizontal mill. Secondly, a somewhat intelligent person can learn to successfully operate said machinery to do a similar task in the timespan of, oh five to ten minutes. Dimensioning the part would be the hardest part of the job. Thirdly, anyone with stable hands, decent spacial ability and a bit of time could successfully replicate the key that engages that cheap-ass lock, from a photo, with nothing more than a key blank, a small vise, a Dremel tool, and/or a file.
Bad drivers are bad drivers, period. The cell phone is just the latest excuse. There's putting on one's make-up, eating and/or drinking, smoking, talking to friends, changing radio/CD, etc. They're all scapegoats for people who are bad drivers and aren't able to concentrate on more than one thing at a time. Don't penalize the phone; penalize the driver.
Oh, believe you me, I've seen drivers doing more and scarier things than this mundane stuff you outlined. My problem with phones, in particular, is that it's a socially acceptable practice, while drunk driving is much less so, and yet it's been proven that a phone-driver is about as impaired as a person with a moderate, but illegal alcohol buzz, if not more so. I hope to see legislation that's a serious deterrent to this activity.
And I feel perfectly justified in blaming the phone for these problems. It's been shown that people driving whilst carrying on a conversation with a passenger are much less distracted than the same driver talking on a phone, hands-free or not. I can understand some of the reasons for this, but it still doesn't seem to line up with reality. I see people with headsets driving much, much worse than people with passengers.
Also, I find the ads placed by tobacco companies, urging kids not to smoke, to be filled with much creamy conundrum-licious goodness.
