What is the overall efficiency of a Hydrogen powered car (including the energy cost to extract the hydrogen) as opposed to one that runs directly off of fossil fuels?

From below, I posted about the efficiency. Here is a graph from this research paper. To sum it up, if you're burning the H2 in an ICE, you're only making the situation worse. PEMFCs can be a little better than ICE vehicles, but they pale in comparison to electric cars.

Thanks, I had always suspected that was the case, I'm glad to finally see some real numbers!

To add information to this discussion, here's the net system efficiency, well-to-wheel, of different energy sources:

That graph is from this paper:

All issues of fuel cost, fuel cell vehicle cost, safety, ozone damage, infrastructure cost, and so forth aside, one of the big complaints about hydrogen is that it's just not that efficient.

Intel would care to disagree.

No they don't. That's why my processor is called the Intel i7 920.

I don't even know what speed the i7 920 is... and I'm a huge nerd. I could look it up, but it's certainly not "advertised".

Perhaps an image would work for you? You can see the wireless page of my modem, with the model number, four different configurable wireless networks, and the speed limiting selector beneath.

My modem isn't even the latest and greatest of Netgear's routers. I only wish that I knew how to root the damned thing, and configure my bandwidth even better than it is. I have a kid who likes to watch movies, and doesn't give a damn how much of Dad's bandwidth is eaten up with them. I've put his mac address on "lowest" priority, and my own on "highest" - but those damned movies still interfere with me sometimes!

You always know a liar if he tells you, 'That'll never fly'.

Let's expose thousands of humans to radiation for several (hundreds, or more likely thousands) generations. Sure, most of them will die horribly of cancer, but perhaps they'll evolve radiation resistance.

Of course, the survivors / evolved ones will end up Looking Like This

In short, there's a LOT of industries out there that are causing more damage than nuclear ever has.

Sorry this is bullshit.
And even if it was not, even if it was true: it would not be an argument!
We had deaths in oil disasters? We had chemical accidents? We had air plane crashes?
And?
I don't get it!
What the heck has that to do with nuclear power generation? Nothing!
You have no clue. Period. Yes, add another Period.
Uranium mining caused thousands of deaths. If not ten thousands. Chernobyl caused 10,000 deaths that are accounted for. And perhaps 100,000 that are not.
Yes, you are right, (how many REALLY know what happened at TMI) I assume 90% of the /. readers have to google what actually TMI means.

So, you know what exactly happened there? And you still think regulations would help?

I fail to understand the entire roll-up computation field. What's the appeal? Why would I want to carry around a cylinder of material that is easy to crush (and therefore crease, likely destroying in the process) when the same item can be made flat, rigid, and slide easily into my briefcase along with other flat things that I need to carry around? Floppy items are no fun to type on. Curly things are no fun to read.

Can someone explain, please?

You don't carry around the cylinder on its own. The cylinder rolls up into a holder device, similar to the communicators on Earth: Final Conflict. The screen unrolls when you want to use it. Marry that with some tubes of electrorheological fluid and you could get a flexible screen that becomes a flat, hard surface when unrolled and current flows through it.

It was hard to look at, so I ran it through The GIMP's auto-white-balance filter. Was this really that hard for NASA's PR guys to do? http://i88.photobucket.com/albums/k196/atari2600a/Ireland_amo_2010284.jpg

Errr. Lifetime yes that is far worse, especially in blues, they have a tendency to reach half their brightness before other colours leading to colour shifting over the life. This can be solved by calibration making it just a life expectancy issue. But the colours comment is completely off base. OLED is the first technology to offer truly pure colours. The three primary red green and blue OLEDs have the same tight spectral response as any other LED or laser, which is to say the colours could not be more pure.

I took a photospectrometer at my Galaxy S and it measured a gamut wider than my NEC wide gamut display. In case you're interested: The resulting graph The light blue line is the standard sRGB response of most screens, the yellow is AdobeRGB and the blue is the OMLED screen on the Galaxy S. So colour gamut wise it out performs even $1500 screens.

The problem is one of driving them. Android doesn't support more than 8bits per channel, the driving hardware is designed for 8bits per channel and the result is that not every displayable colour can be represented without branding akin to cheap LCDs of the turn of the century. But this has little to do with the technology as much as the application of a small, light, and above all cheap device. The other issue is that because the response in non-standard some translation is required to make the colours actually look correct. Android doesn't support this. Heck Windows doesn't support this, and having a wide gamut screen on my desktop, display colour profile support is the one thing that ties me to Firefox despite greatly preferring Chrome from a usability point of view. This won't change till users actively start bitching about the problem, or even start to realise what the problem is.

The reality is that most of the photonics world is looking towards OLED as the future improvement better in every way than LCDs, and the next few years will be very exciting for the technology. Watch this space, don't poopoo the technology in its infancy.

I built a custom hutch for my 3 23.6" ASUS 1080p LED Monitors (10,000,000:1 contrast) that's 70.8" diagonal screen real estate. 5760x1080 resolution. as you can see it's not a gaming rig, gaming is not very practical for multiple monitors.

As for the speakers, don't even get me started. I cannot believe the junk most people use. They'll spend $1500 on monitors (3 Dell U2410s are popular for triple gaming setups) and another $600 on video cards all in the name of a "more immersive" gaming experience and then buy $30 crap speakers to play on. I don't know what it is. Same thing as people who drop $3000 on a premium high end bigscreen LED/LCD-TV, $400 on a high class Blu-ray player, $100 on useless Monster HDMI cables, then listen on the cheap included speakers.

I won't try to claim that they're the best but as far as I know I have the loudest computer speakers in my town.

Keep in mind that Iran is nothing like the United States.

To give a little comparative analysis, I did a Google Maps of Tehran, Capital of Iran, and the first US City I saw, Denver Colorado, and pulled up "Coffee Shop".

It's not just a drive around the corner in Iran.

Here's the thing - we're all gonna die in the end, so all these fights against proprietary formats won't mean jack.

In that case, so is replying. Yet you seem to care enough about justifying your position (perhaps to yourself) to reply, so don't give me this nihilistic bullshit.

In life we pick the battles we can fight. These are potentially important issues, but basically given you're effectively saying about 90% of people are part of the "problem", I don't give a fuck anymore.

When 90% of the people are part of the problem is when I absolutely do care.

Take another battle I've picked: Religion. There's a small minority which does some really crazy shit. And they get away with it in the name of "religious tolerange", because a majority of the world believes enough crazy shit of their own that it takes a lot to make us as a culture say, no, you can't let your child die because you'd rather fucking pray than get help.

Easily 80-90% of the US population is religious, which makes it a safe bet that you are, too -- probably also Christian, probably believe faith is a virtue. If so, merely by supporting the idea that faith is a virtue, you are encouraging yourself and those around you to turn off their critical thinking and skepticism when the situation calls for it. That kind of thinking leads to atrocities. Never mind that merely by calling yourself "Christian", you lend credibility to these fuckwits.

Am I going to win? Not really. I do hope to reinforce separation of church and state, to promote actual science education instead of "Intelligent Design", and to establish some basic rights the religious would deny, like the right to marry. I'd love to see people tolerate less of the extremists. I really doubt I'm going to see the religious become a minority in my lifetime.

But you know what? I'd like to think that when I'm lying on my deathbed, I lived for things that matter. I'd like to think that I'd still be the kind of person who would be ashamed to think I gave up because it was too hard, or because there were too many people who disagreed with me.

Life shouldn't have to be some damn crusade.

You're right, it shouldn't. But this is the world we live in, and there are some issues which tend towards exactly that -- either you're a good little worker propping up the status quo, or you're actually helping to move things forward.

And life should be meaningful -- and it's up to you to find that meaning. Maybe you honestly don't care, but that's not what I'm hearing. What I'm hearing is that you do care, you're just too lazy to do anything about it anymore.

Yet somehow, you're not too lazy to post, and to try to justify how much you don't care. That says a lot.

Why are so many Linux/Mac people so incredibly ignorant when it comes to Windows?

It doesn't work all that well on low-end hardware or virtual machines

Really? I deployed Windows 7 to over 300 Dell Optiplex 520's with 2 gigs of ram - thats a 5-6 year old machine and it runs just fine. Even supports Aero with the integrated video display. On virtualization - you may have me there, but I doubt it. Typically I wouldn't recommend booting Windows 7 on a VM with less than 1 gig of ram at a bare minimum.

Every time you deploy an image you have to manually re-register the thing with Microsoft so it doesn't disable itself

Wow - ever hear of waik (the windows imaging toolkit?) or volume licensing?

Still no decent backup system

Like the built in Windows Backup? Last time I used it - it did actually allow me to restore an entire machine from an image it made and it worked. For enterprises there are tons of of options to backup Windows - like SCCM.

XP Mode is buggy and compatibility in general is bad (especially in the 64-bit versions)

Really? I've only had to use it once, but I got it to run an old Windows 3.1 app just fine and the customer (staff at a community college) was happy with the results.

Still no EXT3/EXT4 (or any Unix-type), Large FAT or GPT support

Uh... yeah there is > http://www.microsoft.com/whdc/device/storage/gpt_faq.mspx

Limit of 2 physical processors? Really? It's easy to get 4 processors in a box these days with 8 cores each especially in the academic world

Really? http://i229.photobucket.com/albums/ee52/skuldchan42/hwmonitor.png - screenshot from my old skulltrail machine - thats 8 PHYSICAL cpu's running Windows 7.

Full Disk Encryption requires TPM chips which are missing in just about any system these days so you still have to go into a 3rd party solution.

Again - not quite. You can use full disk encryption with regular user authentication. But seriously - the only machines that don't support TPM are pretty ancient - like Pre-Celeron 1 GHz cpu...

You still have to download a virus scanner, there is none built-in nor is the OS self-contained enough to be used without one.

The only accurate statement in your entire post, but then - does OSX or Linux come with a virus scanner? And please don't say they don't need one because there aren't any OSX or Linux viruses/rootkits.

Ok here's an easy test to confirm. Get the TV remote, your phone and an assistant. Have the assistance stand outside and point the TV remote inside through the window and press buttons. In the meantime set your phone to take a picture (cameraphones are far better at this than most digital cameras), and just look at the remote through the eyes of the cameraphone. You should see the LED pointed at you light up quite well. This is near-IR passing through.

For the second trick put an infrared heater next to the window, or just stand next to it on a sunny day. This is mid-IR and far-IR passing through. Glass is quite bad at blocking IR, and even "blocking as much IR as possible" is still nothing that would normally stop IR communications or thermography wavelengths.

IR blocking is done on a coating level and is quite visible. Thisis a (scratched) piece of optical glass with an IR blocking coating on the surface.

It is in fact faster or as fast as chrome in version 4 from a javascript perspective, and it has always run on less ram. So it should be much snappier now.

My desktop

There is a reason people have been calling FF bloated lately. This is without any addons, plugins (besides maybe Java), or themes or any crap built into FF. This is a fresh install.

Sure, FF may be working on good Javascripting engines, I haven't looked at the benchmarks recently, but the claim "It runs on Less Ram" died a long time ago.

The dumpster behind 701 First Avenue, Sunnydale, California is technically "outside of the company", and I'm sure that there are plenty of resources there.

If you get there before the next pickup you may even find about six hundred recently laid-off people looking for jobs. I'm sure that some of them may want to do some "resourcing".
