Not at all. A locomotive is not a hybrid, as there is only a single type of motor used for motive power. Calling them 'series hybrid' vehicles only started very recently, when manufacturers wanted to cash in on a buzzword.
If you check out the Journal article, they describe this system as an electric motor mounted on the drive shaft, powered by existing auxiliary electrical generation capacity on the ship. The motor would only be used at speeds under 12kt at maybe 1/10th peak power output, when the efficiency drops off considerably and the turbines are basically idling. The system would be set up to run in reverse, providing power back to the ship, presumably for future electric artillery that the Navy is developing.
There are SSDs sold that connect using PCIe. OCZ and FusionIO have x4 units that run at over 500MB/s. FusionIO and PhotoFast have x8 units that run at over 1GB/s.
The only reason SSDs aren't capable of higher speeds is because the bus is not capable of more. There's no point making a controller capable of 2GB/s if you are only able to transfer at 300MB/s.
The AC is implying that one drive may only use ~80MB/s, but a four-port multiplier will saturate the bus. SSDs are not the only reason to push for increase bandwidth.
This may not be the case anymore, but I had thought support for port expanders on consumer grade chipsets were pretty poor.
Here is an article debunking the claim as a load of crap, and the fact that nothing has come of this 'rainbow format' in the last three years tends to indicate they are correct.
There was an article a couple years back where some Indian engineering student claimed some 2.7GB/in^2, or 4.1TB/m^2, in some 'rainbow format'. With standard office paper at 80g/m^2, that puts a petabyte at 250 sheets and 20kg.
That calculation was just done off wikipedia anyway. I don't know what the price of such a system would be. 'supercapacitors.org' seems to claim they're in use on most hybrid vehicles.
I'll agree that the drive trains in current hybrids are terrible. They give you two marginal engines, that even combined don't amount to a significant amount of power. They give you a complex transmission and linkage that introduces a lot of loss into the system.
Induction motors operate at 90% over a wide range, and can hit better than 95% under high load. Motors could be put directly on the axle with a single speed gearbox to reduce transmission loss (Tesla does this). Supercaps could be used for a short term buffer with next to no energy loss. 25lbs would be plenty to take full size sedan or midrange SUV from highway speeds, to a stop, and back again.
Most commuters will use at least 60+hp accelerating away from a stoplight. Double that if they're driving a heavy truck/SUV.
That's where regenerative breaking comes into play. Regenerative systems will recover 80+% of energy otherwise wasted through breaking. Extra power needed for acceleration becomes irrelevant, and you're back to only needing to size the generator for cruise.
BTW, the fact that it is able to shut off half the engine at low speeds only points out the fact that the engine is grossly over sized and powered for those speeds.
You do understand that your average commute only uses 15-35hp, right? The reason hybrid and gas-electric vehicles are so much more efficient is because their generator only needs to be sized and optimized for average power consumption, rather than peak.
But repeatedly snapping my fingers around my head while stepping forward allowed me to appreciate the changes in acoustics well enough to know where walls and other large objects were. On the other hand, it's not quite good enough to avoid stepping on toys left out by my two year old.
Normally one would just turn on the lights, as it's less likely to wake the two year old than incessant clicking or snapping of fingers.
I'm doing 9x750GB in RAID6 averaging $90 each (some of these are a couple years old) for $0.155/GB or roughly $2.75/HDDVD. If you want to include the RAID card and caddies, it's about double that. I've been buying HDDVDs for $3-4 apiece off Amazon affiliates, but they usually hit you for another $2 each on shipping, and Amazon Prime doesn't work with them.
If I wanted to spend 25G per title in disk space I would be snarfing up those HD-DVDs myself.
You're actually looking at an average 16G-20G per file for HDDVDs, with outliers. Constantine was only 13GB, while Transformers was nearly 25GB. Your point is still correct though. At the price I spent for my hard drives on my current array, and the fact that I lose two disks through RAID6, it costs me about the same in storage space as it did to actually purchase the movie.
As far as US-based launches go, far more gets launched out of Vandenberg than out of the Cape. (I assume you know there are launches from outside the US as well)
Perhaps the reason spindle speeds haven't gone up lately could be part of the same issue. Or perhaps I'm simply indulging in a bit of pointless nostalgia as I wait for this report I'm running to finish. Who knows...?
Close, but not quite. The 'dust' isn't going to fly off, but the disks will expand, throw off track alignment, and risk rubbing against other parts. The platters on a 7200RPM drive use almost the full 3.5", however the platters on a 10K or 15K drive are typically much smaller diameter.
You might be able to make the claim that the establishment is at fault for lung cancer contracted from a long term employee, however a patron nothing says a patron has to eat at your restaurant and be subject to smoke.
Bob & Tom had some comedian, Oggie Smith, on a couple years ago when Ohio passed its smoking bans, who put it rather eloquently.
Oggie: I don't like what goes on at Bed, Bath, & Beyond. I am against it on all levels. But I'm not going to put it in an axis of evil with Baby Gap and Banana Republic and try to ban their existance. I just won't go there.
Bob: I like Bed, Bath, and Beyond. It smells nice.
Oggie: Well you can go there, and you can smoke. I don't care, because I won't be there!
Just log on to the tracker, download shit you own the copyright to, list yourself as a seed, and then sue the shit out of anyone trying to get shit from you.
If you they don't actually upload anything to you, or upload garbage data, you've done nothing wrong. Remember, this is an all-or-nothing thing. You can't get hit with 'Intent to Infringe Copyrights'. If you download a file named as the latest Transformers, and you just end up with another gig of gay porn, Dreamworks has no legal basis to come after you.
If they do upload the actual content to you, they're the copyright owner, and they have intentionally given you the content. Once again, you're in the clear.
You're off by a considerable margin there. LEO launch costs are a couple thousand dollars per pound, with GEO launches about ten times that. The weight of a space based system can be considerably less than a ground based system. You don't need heavy mirrors or solar panels, and protective structures needed to hold their own weight, as well as hold up to high winds, storms, sand erosion, and other maintenance issues. You would stretch out very thin, high albedo Mylar fabric over a collapsing frame, with a couple strategically placed collectors. You could easily cover several thousand square meters (generating a couple MW) with something the weight of an average telecommunications satellite.
You're going to run into a couple problems. The Mylar sheet will be subject to micrometeorite damage, and over time will have to be replaced. You would have to occasionally launch replacements, and design some robotic system capable of stretching the new fabric in place. Your thermal collectors will have to operate at very high temperatures, in order to be able to dump that amount of power through your radiators. You're probably looking at a liquid sodium pump like you see in compact reactors.
In the end, you're looking at free power with relatively low maintenance costs, for a couple billion dollars up front. However with current energy costs, you're also looking at a decade or two before you hit black. Contrast this with a traditional solar power plant of that capacity that would cost maybe half a billion dollars.
On the opposite side, the space based solar plant offers a number of advantages over the ground based one. In geostationary orbit, you provide power for most of the day, entering full shadow for only one hour at night. This makes it much more like a base load plant, rather than peak load. It is also much more consistent power, not having to worry about cloud cover. On a cloudy day, the transmitter could just be redirected towards another ground station. In addition, ground stations can be scattered much more locally, allowing reduced distribution costs.
Without extensive analysis, there is no way to tell something is encrypted, versus someone just dumped/dev/rand onto the internet. Of course that assumed you're in a country where the onus is on the prosecution.
The Sherman tank was never considered to be much of a match for the Tiger tank. You're talking a 36ton medium tank versus a 60-70 ton (depending on the version) heavy tank. The reason they chose the Sherman was because something like the M6 heavy tank that would have been on more even footing was too heavy for their bridging equipment. When they finally starting putting M26 units into Europe near the end of the war, the Tigers could not compete. From what I've heard, the losses in straight tank battles were somewhere closer to 4:1, while the production quantites were somewhere closer to 25:1.
This can in no way be compared to the situation in Iraq. You're comparing two armies in open battle trying to hold territory with one army fighting small guerrilla units. There are completely different tactics in play.
Because if I were designing a jet intended to go transonic, using wood, I'd sure put carbon laminate over the leading edge just to keep the wings from falling off. Even primitive carbon laminates available then had superb stiffness per cross-sectional area, and in tension would give an *enormous* amount of stiffness and strength to the wing in exactly the direction it needs it.
While I would normally agree with you, looking into it further shows this isn't the case. The plywood was made using glue mixed with charcoal dust. There is no additional strength to be had from doing that.
To power the little stun gun set to trigger when they're about to shit on my car.
Sure, the jolt might not actually prevent anything, but at least I'll have some revenge. I just got a wash damnit!
nobody uses video alone like in this test, there's always audio and the audio codec associated with Theora (Vorbis) rocks: same quality as MP3 for half the bitrate. Bits saved on the sound can be used to improve the video; and, yes, it is apples-to-apples comparing the overall bitrate of Ogg/Theora+Vorbis against an all-Mpeg-4 solution.
Using mp3 suddenly makes it not an all-mpeg4 solution. What's the comparison between Vorbis and AAC?
