Diesels are NOT most efficient at WOT. Common rule of thumb is 80% of peak torque is peak BSFC. (Brake Specific Fuel Consumption). This backs up my own data from my car. Peak Torque is around 2000RPM, when I cruise at 1600 RPM I get the best fuel economy.
And an engine mechanically connected to the wheels has MUCH less losses than a driving a generator driving a motor.
Not to mention: Diesels don't have throttle plates.
A large part of it was because the US switched to ULSD. With higher diesel prices in Europe, they could sell their refined product there for more profit. So they did.
And Diesel is a 'byproduct' of Gasoline just as much as Gasoline is a byproduct of diesel.
Not to mention you can make diesel out of coal, natural gas, etc.
For example, a typical gasoline automobile engine operates at around 25% efficiency, and a large coal-fueled electrical generating plant peaks at about 46%. The largest diesel engine in the world peaks at 51.7%. In a combined cycle plant, thermal efficiencies are approaching 60%.
Maybe you don't notice it because you aren't looking for it. The only stations that don't have it in the Widwest are in the ghetto.
And I meant that series hybrids wouldn't make sense to install in cars. In Busses and garbage trucks they'd make perfect sense. You could probably quadruple a garbage truck's efficiency with a genset at peak fuel efficiency and a hybrid drive train.
Comparing the two formulae it can be seen that for a given compression ratio (r), the ideal Otto cycle will be more efficient. However, a diesel engine will be more efficient overall since it will have the ability to operate at higher compression ratios. If a petrol engine were to have the same compression ratio, then knocking (self-ignition) would occur and this would severely reduce the efficiency, whereas in a diesel engine, the self ignition is the desired behavior. Additionally, both of these cycles are only idealizations, and the actual behavior does not divide as clearly or sharply. And the ideal Otto cycle formula stated above does not include throttling losses, which do not apply to diesel engines.
Using the diesel cycle with other fuels has gotten >50% thermal efficiency in the lab, which is DAMN good IMHO.
TDI = Turbo Direct Injection (Fuel is injected straight into the cylinders) SDI = Stratified Diesel Injection. (Same as above, no turbo). IDI = Indirect Injector. (Fuel is injected into prechamber.) Came with and without a turbo.
I've NEVER had a problem finding diesel. If the place you're going has *anything*. It was likely brought there by truck. Trucks run diesels, so the place you're going likely has diesel.
And you will NEVER get more efficient cruising than an engine mechanically connected to the wheels. Buses have a completely different duty cycles to most vehicles and series hybrid won't make sense to install in them. Trains use them as a transmission because a normal geared transmission would be near impossible.
No, modern diesels are nothing like the anemic POS that GM released in the 70s. Mainly because of the addition of the turbo charger (which diesels benefit greatly from), but common rail, higher injection pressures, advances in metallurgy.
My TDI is quite peppy, mainly because the shape of the torque curve. BMW has a 335d and X5 which they are selling here now. VW and Benz have been selling diesels here almost non-stop since the 70s.
That's why I always laugh when Chevy's ads come on trying to sell me this AMAZING 29 MPG car.
I got 48 MPG in a '86 IDI Diesel (that was a bit weak, but who needs more than 50 HP?) I get 45 MPG in a '98 TDI diesel that is quite peppy. I have upgraded injectors and a special chip tune. I bet I'm just barely over 110 HP, if that.
As an alumni, probably not much, but any student that gets caught with a facebook photo taken in the stadium: immediate suspension.
Or they'll give the poor student an option of paying a "Reduced fine" ($2-5k) and everything will be taken care of out of court. Everything done RIAA style against students that can't afford a lawyer to fight this.
The wireless web browsing test uses the 802.11n connection to browse a series of 20 web pages varying in size, spending 20 seconds on each page (I timed how long it takes me to read a page on Digg and came up with 36 seconds; I standardized on 20 seconds for the test to make things a little more stressful). The test continues to loop all while playing MP3s in iTunes... Eight, freakin, hours. I couldn't believe it. In my lightest test, the new 15-inch MacBook Pro lasted eight hours and eight minutes. That's with the screen at half brightness (completely usable) and no funny optimizations. The notebook is just playing music and surfing through a lot of my old reviews. There's no way this could be right. Maybe my test was too light?
I strung together 8 reviews on AnandTech and put them each on a single page, images and all. I then scoured the web for big, animated Flash ads and added anywhere from 1 - 4 ads per page; all Flash. Each page is designed to forward to the next after 10 seconds and the loop continues indefinitely. On each machine I opened three Safari windows and pointed them at the first page in the sequence. In the background, once more, I had iTunes playing MP3s.... Six and a half hours, out of a 5.5 lbs notebook. For comparison, the older MacBook Pro could only manage 3 hours and 17 minutes in the same test. The new notebook lasted almost twice as long. Mathematically, this doesn't make sense. There's only a 46% increase in battery capacity, there shouldnâ(TM)t be a ~100% increase in battery life...ever.
For this benchmark I'm downloading 10GB worth of files from the net (constant writes to the drive), browsing the web (same test as the first one) and watching the first two episodes of Firefly encoded in a 480p XviD format (Quicktime is set to loop the content until the system dies)... The older MacBook Pro managed 3.25 hours in this test. The new one? Just under 5
Going to 'built in' isn't going to add 100% more capacity (3.5 h to 7 h). From the tech presentations I've seen, they use coiled lithium instead of flat in the battery.
Built right into each of the new MacBook Pro notebooks is a breakthrough battery that lasts dramatically longer and does so without increasing the size or weight of MacBook Pro. On a single charge, the battery in the new MacBook Pro lasts up to 7 hours (8 hours on the 17-inch MacBook Pro) and can be recharged up to 1000 times. Thatâ(TM)s compared with only 200 to 300 times for typical notebooks. Advanced chemistry and Adaptive Charging allows the battery to maintain charging capabilities longer and determines the optimal way to charge the batteryâ(TM)s cells. Because the battery lasts up to five years, MacBook Pro uses just one battery in the same time a typical notebook uses three. That makes for less waste. And that, in turn, makes for one environmentally friendly battery.
And Apple is getting 7 hour run times out of their normal laptops.
Then again they actually spent the R&D money to come up with something better. Everyone keeps talking about needing innovations in batteries for Hybrids, Electrics, Laptops, Cell Phones and Apple actually did it.
I haven't heard of any other similar new designs recently (other than, we promise, it's coming soon, we just have to test it real world).
The first one is clipped. The rest go to a pastebinish sites which have gbpm.exe encoded as Base64. It also appears the base64 is different but the exe has the same name (I'm guessing it's changed 'output'?)

Turn SSN's in to Hex Id's. There are now 68,719,476,736 IDs available (With the same 9 digits). The IRS only has to change their data type on their database. I bet a ton of companies would be caught off guard dealing with 'letters'.

Here is how they define a "Social Network". This covers about EVERYTHING from Facebook to ANY phpbb, or forum installation,...
"Social networking website" means an Internet website containing profile web pages of the members of the website that include the names or nicknames of such members, photographs placed on the profile web pages by such member, or any other personal or personally identifying information about such members and links to other profile web pages on social networking websites of friends or associates of such members that can be accessed by other members or visitors to the website. A social networking website provides members of or visitors to such website the ability to leave messages or comments on the profile web page that are visible to all or some visitors to the profile web page and may also include a form of electronic mail for members of the social networking website.
In some states, the age of consent and child porn statutes have the same age limits.
For instance, a quick read of NV law shows the AOC to be 16. Child porn is defined as sexually explicit blah blah blah involving a person under 16. Federal law makes it a crime with a person under 18, but there may be some state line/interstate commerce nexus that needs to be fulfilled.
I didn't feel like looking at too many states, but found this same AOC/CP thing with NH-16/16.
Many states forbid distributing/exhibiting obscenity to people under 18, regardless of their AOC/CP statutes.
SO, excluding the feds, it's not a crime to have sex with a 16 year old or film it. But, she can't watch the tape afterwards. It's a crime to allow her 16 year old friend to watch the act as it occurs, but not a crime to have her join. Neither of them can smoke a cigarette or have a beer afterwards. If either one were to rob,beat,kill one of their fellow participants, they would be tried as an adult in every state in the country.
