Storing the energy by using the electric motor as a generator, rather than dissipating it as pure heat is a win regardless of the kind of engine you are running.
You have failed to explain where you're going to ever USE that energy... Gasoline hybrids shut off the engine when stopped, and use electricity to accelerate. With a diesel, shutting off the engine for a short time is a net loss of efficiency and lifespan, NOT a gain, even IF the energy is free...
And regenerative braking is NOT free. You pay, in fuel, to haul those motor/generators and batteries around with you all the time.
They knew back then how much more efficient it was to have a finely tuned diesel to run at a constant RPM
No. They knew it would be practically impossible to build a mechanical transmission to handle the unbelievable loads required of a locomotive... If they wanted added efficiency, they sure screwed the pooch when they designed dynamic braking to use giant resistors, and throw away all that braking power as waste heat.
Locomotive engines certainly don't run at constant RPMs. There's no battery where the excess power would go, nor to draw on when the supply at a given speed is insufficient. It wouldn't work.
Part of me wonders if the companies have been waiting for some patents on train engines to expire...
Direct-drive is more efficient than converting to/from electricity in the best case, and a huge waste in the more typical case a few years ago... Batteries are still very expensive, and were previously astronomically expensive.
Not to mention that, up until a couple years ago, gasoline was very, very cheap, and even major efficiency gains were deemed worthless at the time, and reasonably so.
And the only alternative to "We're streamlining" or "We're facing cuts" is "We axed these people capriciously, just because we felt like it." So the choice is pretty clear.
This is nonsense. You certainly can tell the truth, and avoid flowery BS spin, without becoming BRUTALLY honest and unnecessarily HARSH about it.
In the case of Circuit City:
"In order to reduce costs, we are giving notice of termination to a small number of employees, totaling X-thousand throughout X-hundred stores. We are contractually restricted from reducing their pay, so termination is the only option open to us. We expect that a majority of these employees will then request to be re-hired to their old jobs at a lower salary, saving the company XYZ million over X years while retaining much of our skilled salespeople."
BS in the corporate world has gotten so thick that it has become self-perpetuating, and we're all forced to swim upstream because of it. That doesn't mean it's necessary, or even beneficial... In fact I KNOW just how often it's quite counterproductive.
Why editors don't ask for this to be clarified or reject outright something making so many assumptions about the field of expertise of the reader?
If you don't know what the terms mean, you're extremely unlikely to care about this news story...
Pretty self-regulating in that regard, except for the few people that feel the need to expouse their views that/. should be dumbed down to the point that it becomes CNet.
Every study done thus far looking at low-carb vs. low-fat has shown that low-fat is a failure (read the studies, not just the blurbs or the conclusions).
Not true in the slightest. In fact, controlled studies comparing the various diets, side-by-side, have found minimal differences between the various approaches.
In short, eat whatever the hell you want, but eat less of it fat ass! You'll be healthier person if you're 140lbs surviving on potato chips than if you're 300lbs with a well-rounded diet.
Anyone claiming their diet plan has any special benefits if either a shill or a fool. If it existed, we'd all know about it by now. Instead, people keep trying every diet, and the population just keeps getting fatter.
Fat, carbohydrates, processed sugars, dairy... eat whatever, just cut down on the calories and you'll lose weight... It's a simple and fundamental law of physics. Simply, find a way to lose weight and you'll get much healthier, and feel much better, rather than being a useless fat blob.
When I had no refrigeration for about a month, and I survived drinking almost nothing but cans of soda, I lost close to 10 pounds. When I was surviving entirely on fast food, I lost weight. When I was surviving almost entirely on carbs (rice, pasta, bread, ramen, etc), I lost weight. 55 pounds later, I can say with confidence, all the trendy diets, and nutritional scare tactics are pure idiocy.
Ok, comparing them to the Wachowski brothers probably isn't the compliment the submitter intended. I would assume...
The Matrix trilogy is FAR from the only movies the Wachowski brothers have made. After the mindless snoozefest that was the Matrix 2 and 3, they came back with V for Vendetta, which bears distinction as a great movie in the midst of all the rest of Hollywood turning out nothing but tripe (Hollywood has only slightly improved since...).
Before the Matrix was a decent movie called Bound, which is a passable movie on its own, but would bear distinction if only for its hot lesbian action between Jennifer Tilly and Gina Gershon.
Boeing's in a lot of trouble if they can't pull off a major integration/rework effort right away. Airplanes are one of the last things the US actually makes and exports from a manufacturing perspective, so it's important that they just drop everything and figure out what's wrong. Airbus will be more than happy to sell A340s, A350s and A380s to all the waiting airlines.
Airbus' entire future was brought into question because of the giant mess the A380 turned out to be... Boeing's delays are certainly no worse, and the canceled sales seems more a result of the decline in the airline industry, and the economy at large, than Boeing's delays.
There isn't much you can do with a box like that other than render web pages these days though.
Avoid the more recent, CPU-hogging apps, and you're good. Blackbox or XFce3, Sylpheed, Dillo, etc, and your box will smoke. It's plenty good enough for playback of all standard-resolution video. The system I'm using as my DVR is clocked at about 1.3GHz.
Hell, I can point to a handful servers I admin, all under 1GHz, which run the core functions of an entire mid-size company.
No... Just YOU. You seem to be in direct conflict with the facts on EVERYTHING you have said here.
They bitch about infrastructure yet they move to VoIP and rip out the copper land lines.
Those of us concerned about our digital infrastructure aren't the ones allowing land-lines to be disconnected.
We push hybrid cars that cost more to produce (in terms of money and environmental impact) than old regular cars, and the difference will never be made up during the life of the car.
Absolutely every evaluation I've seen shows the opposite. Not that I particularly encourage buying into the current generation of hybrids, though.
We want plugin electrics despite the fact that they'll put a huge strain on the already-fucked electrical grid, and will be ultimately be supplied by burning coal.
The Department of Energy says you're wrong. A large majority of people could be driving electric cars without even requiring any upgrades to the grid... In fact they're HELPFUL because they draw most energy off-peak, providing consistent, round-the-clock utiltization of the grid.
Even if coal is solely used, power plants are vastly more efficient than car engines, so you come out ahead. And in most of the country, coal WON'T be the power source.
We have rebate programs to replace your fridge that's been working for 40 years with a new one that will be nicer to the environment but need to be replaced in 3 years.
Humanity hasn't forgotten, some time in the last 40 years, how to make a refrigerator... If you didn't buy a cheap piece of junk that burnt out within 3 years last time, I don't see why you would do so this time...
We push shitty shitty light bulbs down your throat when there's not a damned thing wrong with the current ones.
If your car suddenly started burning 4X as much gas it used-to, you'd definitely say there is something wrong with it... Lightbulb are that way too.
the only legitimate and valid point of view is that of the people, of any country. therefore, if a government maintains power through nondemocratic means, the people's will power has not been consulted. therefore, it is illegitimate. as a simple consequence that those governments don't respect the will of their own people. so why should that government be respected by anyone else?
While you're obviously referring to tyrants, similar claims could be applied to the US after every little dirty trick played in US politics. Or perhaps every time a democratically-elected official makes a decision which is unpopular at the time...
You would think it performs pretty important functions (or did perform) for the 5 percent of short sleepers not to collect more food and proliferate more efficiently and more frequently than the other 95% 8 hour sleepers.
A primitive human is highly unlikely to be ABLE to gather food after it gets dark, no matter how awake and alert he may be. Darkness is like that. Not to mention that there aren't many nocturnal big game species anywhere in the world even after fire had been discovered.
So, since you aren't gathering food very well, you're WASTING IT by being AWAKE, rather than in your 8 hours of hibernation.
Sure, at the very low latitudes, it might be beneficial, but for the majority of the human population, a shorter sleep period would probably be wasted.
Conclusion: formal verification of software is not going to take off any time soon.
Better Conclusion: Assuming the price is reasonable, the world will never need another one... You can run all the buggy and un-verified code you want on top of this kernel, and at worse, that code will need to be (automatically, and very quickly) torn down and restarted when it starts to misbehave.
As it is, it doesn't sound like a pedagogical device to me
I made no assertion, either way. The point is that your argument is nonsense. Clearly, even you aren't actually opposed to educational institutions requiring students to "make public statements defending specific ideas."
I am pretty sure someone's made a IE6 theme for Firefox
Yeah, but if they did it was probably functional for 2 whole weeks. from Firefox version 3.0.3 to 3.0.4, and is now unusable. Try to find a Netscape 3 theme for Firefox, and you'll find the same thing
HINT: I use the Firefox default theme (it's not bad) but not by choice.
No accredited university should be requiring students to make public statements defending specific ideas under ANY situation, trolling or not.
WTH? Have you never heard of DEBATE COURSES. Or how about law school? One side of an issue will be assigned to you, and YOU WILL DEFEND IT, whatever you personal beliefs, or you fail the course.
You seem to think all things must have only one cause/solution/explanation,
No. But when one is life-and-death, and the other is trivial and may be entirely coincidental (ie. unintended), it's only reasonable to write-off the latter until strong evidence is found to support it.
Internal combustion engines run on methane wouldn't be any more efficient than ICEs run on petroleum... That's to say, 25%. Meanwhile, big, centralized natural gas power plants can get 80% efficiency with that same fuel. Even with line losses, storage losses, etc., you easily come out ahead with electricity. Not to mention vehicle costs.
That way you don't need to rape the electric infrastructure, use shit loads of copper, and have so much battery waste.
The grid can easily handle most people driving electric cars, so long as they mostly charge at night and not at peak.
You can use aluminum instead of copper if you prefer, but it means absolutely nothing to anyone else.
Lead-acid battery recycling programs are the most successfu ever devised, anywhere, at upwards of 98%.
How does a company that makes $1,000,000 in profit over 1 full year, get 465 Million dollars in loans from our government??
Because right now they are selling an extremely expensive, high-end product (their first, BTW), and needs the money to expand into mass-market, vastly lower cost products.
The whole idea of making a loan to a business is that they can EXPAND their business operations enough to pay back the loan. That's why a bank must review your business plan, and approve of it, before forking over the cash... They don't just say "You made 10 million this year, so you'll probably be able to pay back $5m per year."
Then for this there's AnyoneEB's interesting reference below.
Yes, but that just WEAKENS your point... ie. no additional method is needed to avoid in-breeding.
Indeed, but can't one of the reasons for this need to set out on their own be our instincts' way of avoiding inbreeding (instincts inherited from the times when they could set out on their own)?
If any, it seems a completely insignificant, compared to the primary reasons (...survival).
What is the reason we (and some mammals) have the urge to set out on our own, whereas other mammals (like meerkats, which then live in clans where only the alpha pair breeds) haven't?
Oh, I'd suspect it has a lot to do with the relatively large land area needed to feed a large mammal.
what better way to avoid interbreeding between offspring and parents than to make teenagers hate/piss off their parents, and do whatever they could to impregnate/get impregnated by someone else?
A) Teen-aged rebellion may keep children and parents at a distance, but it will do the same for children raised by foster-parents. It also does little to keep similarly-aged children of opposite sex apart, so it has no relation to "gene carriers" except in an incidental sense.
B) It's pretty well established that rebellious behavior is simply developing children wanting and needing to begin to set out on their own, and distance themselves from their dependence on their parents. It's only in the modern world where teenagers are forced into a factory-like schedule of education and complete dependence upon their parents until they magically and suddenly hit the age of 18, whereby they can be thrown out to fend for themselves, without having had the time and limited freedom to gradually develop their independence.
The fact that you haven't seen them doesn't change their existence. You also clearly refuse to research the issue at all, since I've provided numerous tips you could easily follow.
Yes, you can find VP6 videos on YouTube. Only a small number have been encoded to that format, compared to Spark and H.264, but they still exist, and you just make an idiot out of yourself repeatedly claiming they do not.
