I am pleased to announce that I found the Holy Grail, Atlantis and three counterexamples to the Riemann hypothesis, and I had some Cocoa Krispies for breakfast this morning.
I'd also call this "analysis" bullshit, but generalizing this lack of seriousness to the "church of global warming" is exactly the kind of dubious extrapolation you're complaining about.
Assuming that the solar irradiance you get on top of the atmosphere is 1360W/m2, 1 square meter worth of solar panel with 20% efficiency (e.g. the best SunPower crystalline silicon modules) would generate 270W of electricity.
Airbus claims that the A380 consumes 3l/100km.passenger of fuel. At Mach 0.85 (~250m/s at 10km altitude), this represents 27l/h.passenger.
Assuming 10kWh/l of fuel energy content and 50% efficiency of the turbofans (pulled out of my...), that amounts to 135kW of mechanical power needed for every single passenger.
Assuming an electrical motor with 100% efficiency, you would need 500m2 of solar panels for every passenger to generate the required electricity, but only during the day.
The plane from TFA seems to have 200m2 of solar panels with 12% efficiency. It can get away with it because it is much lighter and flights much slower.
Conclusion : The orders of magnitude just don't match, even with 100% efficiency => Commercial flights as we know them & photovoltaics are incompatible.
The Minitel was a Videotex online service accessible through the telephone lines, and is considered one of the world's most successful pre-World Wide Web online services.
Exactly. Talking about information bias, I could clearly see from the facts you chose that you're pro-Israel.
Anyone who trusts one side's media or the other, exclusively, is setting themselves up for trouble.
Well it's seem you should listen to your advice. Tell me, do you really think the "Jewish Council for Public Affairs" is an unbiased source for the Arab-Israeli conflict?
The problem with fusion is not that it's hard to make it stop, it's hard to maintain it. If something goes wrong, you don't get any reaction. That's about it. There's only so much deuterium & tritium available during the reaction (cf http://en.wikipedia.org/wiki/File:Fusion_microcapsule.jpg).
PROTIP: Stop caring about the UI, learn some keyboard shortcuts every day, and use Photoshop in fullscreen mode with as few panels as possible (e.g. histogram, layers and layers adjustments)
Welcome my "getting modded Insightful for not RTFA and spreading bullshit" overlords at Slashdot.
Content-aware scaling has been included in Photoshop since CS4.
But this is no scaling, it's filling. The first 3 minutes of the video are not so interesting (nothing one could not do with a clone stamp in 2 seconds), but the last 2 minutes are breath-taking.
GREYCstoration or liquidrescale don't even come close.
Wind power may have many drawbacks (well, just like any other energy source), but you cannot pretend its energy return on investment (EROI) is lower than 1.
Wind & solar power both have EROI of at least 10. Insulating your house has an EROI that is orders of magnitude better than digging for oil.
Now, get off my lawn, and please stop spreading lies.
Plus, the "environmentally-friendliness" in function of the population density is *not* monotonically increasing.
There's an optimum somewhere, but I can assure you it isn't attained in LA or in Shanghai. All the food has to be imported from at least a few 100 miles, people having to commute from one side of town to the other have to stay in traffic jams a few hours a day, and the heat island effect has a huge impact on air conditioning and electricity demand.
As far as TFA is concerned, environmentalists have to take minimum standards of living into account or they're just being assholes.
About a thousand things, but to me, that would be :
- integration with a powerful and easy to use RAW processor (Camera Raw or Lightroom) - non-destructive processing with layers styles and adjustment layers - developed, used and tested by many pro photographers and designers for the last 20 years
GIMP doesn't even come close to PS for my workflow.

Why not capture the 18mm of your lens?
You'll get even more information!
You sir, don't understand your camera.
Here's a nice explanation about the difference between tonal range and dynamic range:

The 550D has a 14bit AD Converter, but offers a bit more than 9 stops of dynamic range.

Care to read the article you link to?
Exactly.

Holy fuck, thanks mate!
I was really frightened and saddened to not see anyone mentioning this.
Yes. Just wait until oil reserves are depleted enough.
I stopped flying 5 years ago because widespread civil aviation won't be available forever.
If you know you have to stop smoking some day, why not today?
I didn't read your post, but everything you wrote is wrong.
You know, we'll have to find alternatives anyway before oil becomes too expensive or too scarce.
Short of nuclear power, we don't know any kind of energy storage that has a suitable energy density.
Your age surely isn't an excuse to write the utter load of BS that you call a /. post.

Thanks a lot for mentioning this book.
I just read it & stopped smoking after 10 years of nicotine addiction.
+1000 insightful!
The . as a thousands separator should die.
Especially when there's no decimal separator around.
Put a space if you really want to make it easier to read :
13 000
13 000.00
13 000,00
but
13.000 is just plain wrong.
How hard can it be to not mess up units while talking about energy and power?
How far can a 80 mph car go?
Well, "Fuck YOU", because Mac OS X that's the only *NIX platform that runs Photoshop, Lightroom & Cinema 4D natively.
I sure won't buy any IPad, though.
Anal sex FTW!

This is probably as SERIOUS a SHIT as Irak WMD's in 2002.
Well, since Debian can run on FreeBSD, there's no contradiction there!
Still funny, though!

No problem here, a grammar nazi can still have spelling problems!
