Biofuels are horribly inefficient solar energy collectors and converters. Just another reactive diversionary goose-hunt to avoid coming up with proactive solutions that dig into the heart of the problem.
RTFA.
Stop beating-around-the-bush and go straight to the horse's mouth with something such as the Stirling solar concentrators that convert to electricity ~25% efficiency, or PV that can go up to 30% efficiency.
They'll take less land, no years-long pipeline that'll put up more air pollution, need no fuel and petroleum-based fertilizer to run the conversion process, and just requires we come up with better energy storage in either batteries, or fuel cells (as pipe dream as FCs are).
Hower, the problem is growing that much stuff is still a net energy loss unless you really don't use any chemical (read oil-based) fertilizers. I also ponder where the energy is going come from for processing waste water, or to desalinate it.
Afterall, the point is to produce fuel that has zero to neutral environmental impact, and still be a positive source of energy.
Instead of going through the whole wasteful process of using plants to convert solar energy into biomatter to burn in an inefficient combustion process, why not directly convert it into electricity using those Stirling-engine solar collectors. Then use it it to grid power mass transit trains, or even battery powered cars. It's been calculated you can get much more usable power from using that corn land for solar collectors instead.
Biofuels are a cute gimmick in the small scale, but once you scale it up, it's going to be very, very expensive. Do we have enough land to grow it?
There's no way it can suppliment our current consumption needs, and where is the water going to come from to grow it? We lack enough drinking water for everybody as is.
Considering it was competition with Babylon 5 that forced DS9 to get more gritty with its writing, and not maintain that fluffy "it'll all be okay"ness of normal ST stories. Of course, this carries over into BSG.
Maybe that's what SG is missing now, that grittiness from the beginning.
Alternatively, in Doctor Who's weight-class is Gundam, which has been around as a giant-robot militiary/scifi for around 25 years, and too many series to count for me.
Another reason to dislike Atlantis. It's lost the archaeological/discovering story telling of SG-1, and everybody in the Pegasus Galaxy happens to speak English.
I think what you're really arguing is for work/task loops built up by message passing. These work queues can either be a different threads, or processes, and spend most of their time looping through the queue, instead of being created&destroyed per "user".
Fair enough. Get and use what meets your needs, and the choices aren't as bad as what TFA makes it out to be.
Don't forget to take in account that diesel has roughtly 10-13% more energy content by volume which skews any direct MPG/LKm comparison between petro and diesel.
transmission: differential (planetary gears about been around since the Model-T) engine: been around for years electric motors: AC motoros have been been around for years LCD multi-function display: what are you looking at? LED speedo: seen it in a 1984 Ford Probe computer programming, integration, and wiring: does it really cost that much and what's so new about it? aluminum hood and hatch: this is new tech?
Also, if a new Prius comes out using the latest Toyota hybrid tech (in the Highlander and the 400h), it actually will have a dual instead-of-single planetary gearing. Slightly more complex, not simple, as auto "guru" Spinella suggests. In fact, already in production before GM's magical/revolutionary dual-mode hybrid tech.
Prius got no timing belt nor alternator, barely uses the brakes, the 12V battery is charged by the traction battery when on, ICE is only on like 50% of the time...
I call same.
And, they don't use Hummers in the military, only humvees. So the Hummer is an Expedition with a big factory kit on it. Hmm, got an itemization of what these "repairs" and lifetime costs are for the Hummer?
Sorry, I wasn't trying to draw an American vs Japanese argument, just it seems to boil down to such many a times.
So sure, considering hybrids first started selling ~1997, and the most popular version is the 2004 generation of the Prius, 7-8 years for battery replacement is pulled out of nothing; do the math.
I don't know how much energy is used to create the battery, but the battery is fully recycled (Toyota offers $200 bounty), it has a 150K mi warranty in California (100K in some other states). Also, the battery SoC is kept between 40% and 80% constantly with no deep-cycling under normal usage, it's not mistreated like a cel-phone/laptop battery, and so tends to last a long time as current real history is proving. No Prius has had it's battery replaced due to age yet.
Batteries cost $3000 USD retail ignoring junk yards for parts, and the price of technology constantly deflating due to economies of scale and such.
A well-known Canadian taxi driver has already bruised up his taxi Prius well over 200Km http://www.msnbc.msn.com/id/8839690/ with no battery replacement.
It's relatively safe to say a Prius will last as long as any other vehicle on the road under normal care which happens to be a lot of just rotate tires and oil and not much else.
If find it strange some single out the Prius when most don't even keep their other vehicles past 10 years. I think the energy calculations should include the amount needed to produce the gasoline used by the vehicle by the amount the vehicle uses, lifetime.
Then some personal hard numbers (making me probably biased:P): $3743.90 petro $ 144.20 oil $ 740.05 service $ 356.22 tire replacement $4984.37 total over 62399K miles ~ $0.08 per mi.
Maybe it's "The Age" that needs to be supporting its position with real numbers...
TFA failed to note that the environmental impact dates between 1930ish and 1992, and years before the appearance of any nickel-battery hybrid vehicle. TFA also fails to note how much of the nickel there goes to Toyota and how much to Toyota's hybrid battery usage. It seems to be a great whitewashed assumption.
If anything, World War I and World War II used most of the nickel from there. Maybe TFA should've checked its sources a bit closer.
Can I ask when has a Prius had to EVER replace its battery in its normal 200K mi+ lifetime? (Toyota recycles batteries btw and a 150K mi warranty). Remember, the vehicle model has been around 10 years (1997) so plenty of history to look up.
Also, it's hard to imagine how a Prius contributed to Sudbury's problems considering it was built in 1972 and rehabilitated in 1992. Did it build some sort of time machine too? Or maybe it came from all of the rest of the vehicles and batteries sold up until the hybrids became a reality in 1997?
And where is the evidence that an American vehicle actually lasts 300K miles vs a Japanese vehicle? We all know TFA is FUD.
I agree.. if anything King's Quest was just a graphical evolution of Zork from a long line of text games with intelligent parsers. Albeit KQ's parser was not really on par with Zork's.
Somewhere around King's Quest V? the text parsing aspect disappeared to be replaced by point and click which Myst and that The Dig eventually derived and evolved further.
I miss the parser interface, but some of the text type interface still survives such as in NeverWinter Nights.
... ignoring that Herzog_Zwei on the Sega Genesis heavy influenced Dune II which preceded to kick off the RTT (Real Time Tactics) genre.
Real Time Strategy games is a misnomer since strategy involves moving troops around like Risk and resolving battles at the macro level; not micromanagement of individual units as most of the games currently play. Making units dance in Warhammer 40K to confuse the AI lock-on? Come on!
Maybe there'll be a more *BSD-like Linux distro someday that doesn't make the core OS dependent on so many external user level packages, or at least allow core packages to coexist with user-installed packages, such as 2 versions of PHP, or stuff like python as python's native install already supports.
Some reason,/usr/local |/opt seems very forgotten.
Funny enough, *BSD and pretty much anything that supports pkgsrc, Debian, Ubuntu, Linspire, Freespire all happen to support multiple different versions of different packages within a single "distro". Many support it for FREE.
Some even allow multiple version installs at the same time as is intended by the software program (multiple gccs, pythons, etc) instead of some single "blessed"/core system version.
Why do packages have to be vendor locked to the OS release? We don't put up with it with Microsoft's stuff, but it's okay because it's Red Hat?

Win2K is the last one to support POSIX: http://support.microsoft.com/default.aspx?scid=kb; en-us;308259
You probably mean CreateProcess(), a Win32 API.

What new fuzzy new technology is this?

engine: been around for years
electric motors: AC motoros have been been around for years
LCD multi-function display: what are you looking at?
LED speedo: seen it in a 1984 Ford Probe

You can cancel your $1200 extended warranty and get the same for $990. Check priuschat dot com.
You'll never make your money back buying that Nav over a Thomas Guide. Of for that matter, a Hummer, SUV, luxury, big engine vehicle vs a go-cart.
These are all poor straw-mans against one's buying choice.
And I haven't yet seen the argument balance on the tail side of people's health vs emissions of either vehicle.
http://www.greenhybrid.com/compare/mileage/toyota- priushsd.html has extremely well-documented average Prius mileage at 48MPG. Coincidentally, matches the new EPA numbers.
I call shenanigans on you and your "friend".
$3000 http://hybridcars.about.com/od/hybridcarfaq/f/batt erycost.htm to replace the battery, retail, if ever... How much to replace a transmission/rebuild an engine when close to 200K-300K mi?

Around 1992. Years before any hybrid vehicle existed. Doesn't it make you wonder?
Wow, for $6000-7000 you could buy two real hybrid batteries at retail prices! (ignoring the usual deflation of prices for technology as time passes)
Now, I'm starting to doubt your 100K figure too.
How much does a transmission rebuild cost? Smells the same $3K.

You would think they learned from this so many years ago. Guess not. Just because it's programmed in, say Ada, does not protect you from logic errors.
So what's the next boundary condition, flying over a pole?
