Itunes is possible the number one reason I switched back to a PC from my macbook. I simply can't stand it. It's bloated, laggy, and just a plain mess if you ever need to do anything complex to it's god-awful database. And if you wanted to offload your massive music collection to a netwroedk location....impossible. Back in the day I wanted to run itunes off a NAS drive - mother of god was that a mistake.

The point was not that carbon capture was bad or ineffective. The point was that the efficiency was so low that they had to supplement with conventional CO2 supplies. The enthusiasm is good, but it should be tempered by the reality that the process of "air-to-petrol" is essentially academic at this point in time.
Buried at the bottom of the article is this tidbit:
"Although the prototype system is designed to extract carbon dioxide from the air, this part of the process is still too inefficient to allow a commercial-scale operation.
The company can and has used carbon dioxide extracted from air to make petrol, but it is also using industrial sources of carbon dioxide until it is able to improve the performance of "carbon capture"."
A-freeking-men. The guy is only succeeding in cheapening the appearance of a P.E. - precisely the opposite of what he intended. Lacy should get fired for being unresponsive to legitimate concerns from the citizenry, as well as being a pompous idiot.
With the ridiculous number of stories and reports that have continually made it obvious that paypal screws people, I'm at a loss why anyone would use them for something this serious.
I mean, I feel bad for him and all, but at the same time - what a ridiculously stupid thing to do.
Attack of the Clones was far worse. Sillier story, even more breathtakingly unnecessary market-driven hoopla and the dialogue goes from "it's a small child and consequently this is bad, but tolerable" to "omg, who wrote this utter drivel and why did these actors defile themelves by partaking in it?"
I see this being, like diablo III, just an easy way to get more people to pay monthly for bnet access. No thanks.
I found dealing with all of the adolescent assholes on bnet bad enough with Diablo II, I'm certainly not PAYING for a laggy experience filled with bigots and idiots.
This is the same guy planning to drain the Olligalla (sp?) aquifer to supply southern texas with water. Private water rights being abused, right before your eyes.
FWIW, these two projects (the wind farm and the water system) are really the same
This may be the most uninformed and ridiculous comment ever. Having kids does not mean you can't do what you love. It means you get to share that love and passion with a person so enormously important to you that everything else pales in comparison. It's the best feeling in the world. You say you should throw what you love away when you have kids - I'd say you have no idea what love is until you have kids.
People like you are just compensating for your complete lack of original ideas, convictions, and security. You're probably 23 years old.
Too much money involved to not get the attention of some politicians. In terms of "do-ability", the real question is how the shuttle managers will get around the lack of spares/supplies that have been minimized and/or completely shut down in preperation for the retirement date.
Each tile is 6x6 inches. The damage is about 3 inches long. Length however, does not matter - it's all about depth. In this case, the tile is 1.14 inches thick, and it is believed that the damage is through the entire width, exposing the filler bar/RTV adhesive under the tile edge. This implies no ceramic insulation for the aluminum skin. Before more slashdot armchair NASA engineers make ridiculous claims, understand that fluid flow into a cavity of this geometry will choke, lowering the heat rate. Also, this damage is conveniently under an aluminum structural assembly, giving the vehicle significantly more dissipative capacity. I think you'll see this thing cleared for reentry.
In this case, as the gap filler is pretty far forward on the nose, the boundary layer is very thin and easy to trip. The position is key - forward and slightly outboard so that it overheats the WLE. In fact, one could argue that this is quite possibly the worst possible location for a protrusion of this size.
NO. Boundary layer transition is not a very well understood phenomenon to begin with, and in this case you pushing the limits of both flight experience and analytical capability. Going from laminar to turbulent flow above mach 18 results in some very serious heating, ultimately effecting not just the thermal system, but also the structural margins.
Most importantly, this trip would spill over the side of vehicle and run down streamlines into the wing leading edge. Analysts put the increased heat loads even in a "best case" situation at 80% increase. At those temperatures (almost 3300F), the SiC coating will start to degrade. Dispersion in the entry tajectory could lead to an additional 150F. At that temperature the SiC will ablate, exposing the carbon-carbon substrate. It will oxidize and the temperature will skyrocket to 4000F. At that temp kiss the wing goodbye.
That all being said, I think it could make it down - the uncertainty in this situation is increasing conservatism - but I sure as hell won't take that risk when the EVA is quick and relatively simple.
As someone who works at NASA on the SSP, let me tell you a well known axiom:
"Every shuttle launch entails putting roughly 4.5 million tons of weight into orbit - and closing out about twice as much weight in paper."
Jokes aside, most of the paperwork is there for a good reason. Every single component on the shuttle is certified for the entire flight envelope. It's quite a challenge.
Doesn't this reek of Orwellian doublespeak? I mean - the privacy board represents a group of people who want to circumvent privacy. The PATRIOT act is the most un-patriotic legislation government action since COINTELPRO. Etc.

Which all but guarantees that this engine will never do anything more.

Great story but this "writer" makes me want to punch my computer screen. PAINFUL.
Nuff' said.

Even if your super-crazy scenario comes to fruition, the rest of the world can always decide not to trade with countries that utilize such methods.

You know, like Iraq or the defecit or health care?
What a screwed up country.

30% on the tile. 80% at mach 19 early boundary layer transition on the WLE.

True, I worded that badly. I must need another cup of coffee.
