Wanna play? I modified the script to calculate a password for every month of 2011 (http://www.pastie.org/2167031).
Here are the 12 passwords that I get with a master password that is 8 chars long, with upper, lower and numbers: 1d8ZbrQ7 cnuIGh2Y g6IqOjbF oKg18Qla c4mL0OD/ Eo4Z4o2l HizvMi1H s5fm8Rwv 9pciKJ8P DmFBJZv1 ojAcAj70 o8UEd8dd
What's my master password?
Maybe you could find it with rainbow tables (I doubt it), but you won't if I use a.jpg of my cat as a master password.
*) Choose a master password. *) Never forget it, never disclose it *) Concatenate it with "MonthYYYY" *) Calculate its SHA1 in base 64 *) Ensure that the 8 first chars contain upper, lower, number. If not, concatenate i+=1 to the master password and keep hashing
It looks like this In Ruby: http://www.pastie.org/2163871 An example with P4SSW0RD as master password gives : OWRhNGE5
Last time I checked, nukes produced 23% of German electricity in 2010. (http://www.germanenergyblog.de/?p=5436)
Yes, the steady PV growth has been impressive in Germany during last few years, but it still doesn't mean that Germany isn't switching to coal: Renewables produced 17% last year. So it means there is "only" 83% left. How hard can that be?
The majority doesn't even understand what it's about. Newspaper don't care to explain what is it, and why it could be bad. The minority who knows about it and gives a damn knows how to circumvent it, and use SSH/proxies/neighbour's wifi.
"A theoretical efficiency of 92% was demonstrated at a peak resonance of 10um"
Take a look at this graph : http://en.wikipedia.org/wiki/File:Solar_Spectrum.png 10um (=10 000 nm) is not even on the graph. Why is that? First : the sun doesn't radiate that much around this wavelength. It corresponds to approximately 290K (~17C) black body radiation while the sun is at ~5800K. It is as much solar power as "human power" or "earth power" or "whatever in the neighboorhood power". Then: at this wavelength, the energy of every photon is 20 times less than those that are absorbed by usual solar cells. Which means that less than 0.1% of the solar radiation is available around this wavelength (see http://en.wikipedia.org/wiki/Planck's_law#Percentiles).
If you integrate the efficiency curve multiplied by the spectral irradiance of the sun, you probably get less than 0.1%. Now, that's impressive for a theoretical efficiency!:D
While I mostly agree with your post, I'd like to say that Dutch and German are pretty similar. It might hurt your pride, but they're basically the same language with a slightly different grammar and pronunciation.
I can speak 5 languages, but I'm really not sure I could tell the difference between Swedish and Danish, or even Japanase/Korean/Chinese, especially if you take different accents and pronunciations into account.
If you think I'm a numbnut, well, you know where you can shove your West Germanic language.
The green folks are pretty clear on what they want to see:
Smaller flats, less heating in winter, less AC in summer, bus-tram-train-bike-friendly-urbanism, less cars, less meat, more regional & seasonal vegetables, less useless products that are thrown away after 6 months, and only *then* widespread use of wind and solar power (+biomass, +cogeneration, +geothermal, +some nukes, +hydropower,....)
Or you know, the power delivered by 350 horses! Yep, definitely too much! I agree this is overkill, just like almost 100% of every car on earth, even the "small ones".
I'm not just sure if you're just trolling, but here goes:
* The only green energy is the one you don't use. Reducing our consumption is the only way to go. Still, it doesn't prevent us from saying that solar power is greener than coal or oil.
* Very diffuse? Sure, every energy source is diffuse compared to fission, fusion or oil. But in most European countries, producing 100% of the energy demand with solar panels would require to cover about 40% of the available roof area. It would be stupid to do so, but 50% would be desirable and achievable with solar, without impacting anything else than existing buildings.
* Well. We know the impact fossil fuels have on climate. The advantage of solar is that it only takes a tiny part of an energy that would fall on Earth anyway, and releases it as heat after having been used as electricity. Where's the problem?
* Nuclear and solar could live happily together. I know solar and wind have their own problems, but I can honestly say I don't really care about them compared to the shitloads of problems we'll have with "business as usual" and oil+gas+coal. Once again, we should just try to reduce our consumption. All of a sudden we don't need that many nukes, that many windmills and aren't dependent anymore on rogues states that happen to have oil/gas.
I've been to PS10 & PS20 (close to Sevilla, Spain) : http://en.wikipedia.org/wiki/PS20_Solar_Power_Plant You can't believe how bright the rays are close to the tower, and I sure as hell would'nt like to fly there. Still, one of the workers told me they do find an occasional fried bird.

My master password *is* P4SSW0RD in this example.
Solution?
*) Choose a master password.
*) Never forget it, never disclose it

Yeah, too bad they're lying about the efficiency while conveniently ignoring thermodynamics.
Sorry, but that is utter bullshit.

Now, that's impressive for a theoretical efficiency!

Well, the problem with your logic is that we don't pay anything for oil : we only pay the middle-person that extracts/refines/delivers it.
I'm not just sure if you're just trolling, but here goes:
* The only green energy is the one you don't use. Reducing our consumption is the only way to go. Still, it doesn't prevent us from saying that solar power is greener than coal or oil.

Well, duh.
It's almost as if our average speed was linked to the availability of cheap energy and the days of cheap energy were coming to an end.
