I wonder about this whole levy thing. Is it a good idea? It can increase the areas we can live in but what are there probabilities of failure. How robust can they be made and what measures are in place for if they fail. I really can't gauge the whole cost benefit of them.
To understand the ultimate benefits of levees, you should look at what would happen without them. New Orleans would go away immediately, of course, but wait long enough and so will Baton Rouge, Vicksburg, St. Louis, half of Chicago, most ports along the Mississippi and Missouri rivers, a quarter of Kentucky's farmland, several small gulf coast and atlantic ports, etc. Flooding would see to what land subsidence did not. The US levee system is vast - much bigger than most people realize. Its construction was the rural electrification of its day, and it has become one of the unseen backbones of our economy.
That's part of what makes it so difficult to go back and try to mitigate some of the damage levees cause: we desperately need them.
Not everything coming out of this is bad. Believe it or not, small hurricanes actually tend to help local economies. They create construction booms. My (foolish? brilliant? ruthless?) brother is already sneaking around north of Lake Pontchartrain to gauge the local business potential for his contracting business. Many more will follow.
However, the destruction from Katrina is so extensive that it may take a year or more to slip back into the "construction boom" economic regime. And it's starting to look like some of the population redistribution it caused will be permanent. If just 10% of the people who evacuated decide they aren't going back, it'll be the economic equivalent of my entire city just packing up and leaving one day.
your focus on a tiny portion of the issue (new studies) demonstrates that on the larger issue you are simply OUT OF AMMO!
That's a pity, because New Orleans is going to need all the donations it can get. Cobra Commander could still contribute other materials and supplies (besides ammunition) to the effort, however.
Big, big picture? Maybe New Orleans should have been abandoned 50 years ago.
Well, the small picture is that it could be abandoned 50 days from now. Know any place we can put 1.5 million refugees?
How about cancelling improvements to the exact levee that broke because of the need to fund our operations in Iraq?
Hurricanes happen, it's just a fact. This last one was by no means unusual. Cities built on flood plains will flood. Trying to imply that a study on a single levee being cancelled somehow made the damage worse and that it's the direct result of the Iraq War is political propagandizing at its clumsiest.
I must concur. New Orleans has known for nearly a century that its levee system was inadequate to withstand a storm of this magnitude. By the late 1990's, parents in New Orleans were no longer using only ghosts and goblins to frighten children. "The category five hurricane will get you!" was becoming the scarry story of choice. Blaming Katrina on the Bush administration is completely illogical. It could just as easily be blamed on the Johnson administration - Andrew, not Lyndon.
There was much that could have been done to prevent it over the past century, but the Clinton and Bush administrations' were the first federal efforts to even try since the 1940's.
PS: Don't count on the pumps to save New Orleans. Most are currently sitting idle until the Lake Pontchartrain levee breaches can be repaired, because, in the epitome of engineering oversights, they pump out into Lake Pontchartrain.
PPS: And have since before George W. Bush was born.
I think that about says it. :cry:
That said, watch for Turkey and Iran and Syria to balk at a "too successful" Kurdistan.
Yes, that scenario could lead to a "Kurdish Iraq" just as easily as a "Shiite Iraq" - a "successful Kurdistan" without an actual Kurdistan.
Not a good idea. Oil having just climbed above seventy dollars a barrel...It is better that Americans pay real world prices for their petrol rather than risk draining the security reserves. Private sector needs to change its posture.
Yes. Depleting oil reserves is a bad idea right now. However...
I suspect that Kenneth Deffeyes is correct. We are near the point of peak oil production, which means we are at the cusp between a buyers market and a sellers market for oil. In the world oil market's current economic regime, queing (when you order, where it comes from, and how fast it's shipped) has more effect on price than the interplay of supply vs. demand. We are now in a worldwide version of "the Market Game", as described in Chaotic Dynamics textbooks. In that case, a stable source (like the strategic oil reserve) can stabilize prices more than any increase in supply.
Hurricane Katrina has just halted about a third of US oil shipping for the next month. If the strategic oil reserve can make up that difference for one month without depleting it, then maybe it should be used to do so. That one month might keep US gasoline prices under $6/gallon for another year.
However, SpaceNut, I fear that extending that intervention over an entire season might rob us of the ability to do it again. We should not do that.
If your heating bill gets too terrible, you could consider coming to live in New Orleans. I hear they'll have lots of room... well, space, anyway.
Katrina had passed by with major levee failures only in Bernard Parish and outskirts of the New Orleans area. For a few hours, it was believed that the worst case scenario had been avoided, and some news feeds are still reporting that information. However, the storm surge backed up into Lake Ponchartrain remained, and overtaxed levees began failing last night after the storm had ended. Portions of interstate highway 10 have been swept away and 80% of New Orleans is flooded. The waters are still rising as Lake Ponchartrain pours into the city.
For comparison, while the Great Lakes of North America as a system are larger than Lake Ponchartrain, no single one of the Great Lakes (Lake Michigan, Lake Ontario, etc.) is larger than Lake Ponchartrain. Imagine the Chicago area if Lake Michigan went up twenty feet, and that's New Orleans this morning.
Biloxi, Mississippi, near what has suddenly become the mouth of Lake Ponchartrain as it empties into the sea, is still flooded as well. Biloxi also suffered significantly more wind damage then New Orleans. There are unconfirmed reports that the penninsula which used to form the west side of Biloxi Bay no longer exists.
And Katrina is still a coherent storm system. The state of Kentucky, almost a thousand miles inland, is getting their first tropical storm in decades.
I think Katrina is about to exceed Andrew as the most costly storm in US history.
The funny thing is that this is Osama Bin Laden's worst nightmares. Muslims fighting each other.
LOL! He's sure got a funny way of showing it!
I have another scenario for the future of Iraq:
The Iraqi constitution passes because it serves and is supported by the two largest cultural groups in the country. It's infamous "succession clause" turns out to be functionally meaningless, and the kurdish states - already the most economically stable and sitting on a fine oil reserve - become the economic powerhouse of the country. The shiites play along because they are allowed a legal existence partly independent of secular law (courtesy of the successfully ratified constitution) and are now economically well off again for the first time since Sadaam came to power. And the sunnis get the political leftovers, because they refused to come to the table when constitutional concessions were being served.
The shiites and kurds come out of it with a country, and the sunnis come out too weak to do anything about it.
Sunni led terrorism in Iraq continues, but so does Iraq.
It wouldn't be perfect, but it wouldn't be part of Turkey or Iran, either.
JP Aerospace claims that their design process for this airship to orbit thing has been underway since at least 2002, and they've had the physical model for an all-airship ascent for much longer than that. Both John Powell and Al Differ at JPA have stated publicly that no undeveloped materials (e.g., unobtainium or carbon nanotube anything) would be necessary for the project, and all of their anticipated contruction materials had been used in high altitude ballooning for years.
So, no, they were probably not holding out for CNT fabric.
Katrina has weakened to Category 4 at landfall. New Orleans is still screwed, though. That city is already getting hurricane force winds, and the closest approach isn't for hours.
Outcoming footage showed flashes of light in their stormy skies. It wasn't lighting; it was transformers. The south side of New Orleans is already in the dark, and the rest will be soon.
The worst case scenario is 1 million people homeless by this time tomorrow. (Florida had worse last year, but it took all year to do it.) I really feel for those people who couldn't get out of New Orleans, or worse, are now stuck on the coast.
This update is coming late. I’ve gotten into a bad habit of just googling and blogging for my news on this topic rather than actual research, and so I didn’t come across this information until it was five months old. JP Aerospace has been relatively quiet about it, but it could pose a major financial problem for them.
According to a series of articles in Aerospace Daily & Defense Report, The US Air Force is planning to renegotiate their contract for JP Aerospace’s Near Space Maneuvering Vehicle (NSMV) on the grounds that it has failed to produce results during testing.
According to the articles (AD&DR 20 Oct 2004, 2 Nov 2004, 5 Nov 2004, and 18 Mar 2005), all USAF testing of the NSMV was handed over to Global Solutions for Science and Learning (GSSL) in 2004, who examined JPA’s ascender prototype. GSSL declared that the prototype could not fly because of propeller problems and other unspecified “engineering oversights.” They delayed testing to upgrade the NSMV and exchange the propeller with one of their own design.
GSSL flew two of its own scientific balloons to test their own propeller design prior to putting it on the NSMV. Both flights suffered mechanical failures and returned no results. GSSL declared the NSMV tests a failure, and the Air Force has followed suit. In March 2005, the Air Force announced that NSMV had not done what they expected it to do, and they were now looking at “an appropriate investment strategy to manage to risk of the project.” I have no data about the current state of JPA’s contract, but their USAF support is no longer unqualified.
If USAF withdraws completely, this could be devastating for JPA. Which would be a shame, because, IMHO, the GSSL testing was inconclusive. The GSSL report, while potentially damning, was based on design analysis only. All equipment failures were of GSSL hardware; no JPA hardware was ever flown during six months of GSSL stewardship. Given that JPA claimed to have already conducted successful tests of its propeller and other ascender prototypes prior to the USAF tests, the question of NSMV’s failure is a matter of JPA’s word against GSSL’s.
GSSL’s position as a competitor for similar USAF contracts does not lend it increased credibility in this instance, but its prior record as a contractor does, and they insist NSMV won't fly. If USAF dumps JPA completely, JPA may find it has only two choices to maintain continued credibility with the rest of its sponsors: release its own test data, or fly a working ascender prototype itself on short order. Either would show up GSSL. Neither is a particularly attractive choice.
Katrina is now a category 5 storm, the fourth largest ever recorded in the Atlantic Basin. It is projected to make landfall just south of New Orleans tomorrow morning. Its projected storm surge is 20ft, with 40ft waves on top of that.
Like Amsterdam, New Orleans is largely below sea level. It is protected by an extensive system of levees (dikes), but these can only stop a flood 13 ft high, not 20.
Every major road to New Orleans has been blocked off by the state police and converted to a one way street leading out. They are evacuating the city before Katrina turns it into an extension of Lake Ponchartrain.

Just read C. Baldwin's "You Might Be a Constitutionalist If..." (linked to Randy's web page). Most is okay. I'm definitely not in agreement with #15, #25 and #19, though.
My list is longer. I'm afraid I'd get a failing grade as a constitutionalist.
Still, it's a neat idea. Perhaps every political party should offer an "agreement test" like that one. That way you could figure out your score for each party - 60% Constitutionalist, 85% Green, etc. Democrats and Republicans might be disappointed by their own scores, though...
Bit offtopic, but I recently discovered I'm a rather hard-core neo-Darwinist... The hard way.
i.e. all but breaking up a relationship because of someone really believing the Earth is tens of thousands years old, instead of several billions.
Or I'm a hard-core non-Christian? :?
I've seen this before, I'm afraid.
Apparently being a literalist fundamentalist creationist makes people less likely to reproduce with members of the general population, creating a distinct sexual selection tendency toward people of their own kind.
We could be seeing the development of a new subspecies. :shock: ( )
CMEdwards, what do you think?
I think we need Mars Express to go look for water vapor.
I don't agree that the proof is definitive. Might be water, might not. As we saw up close in Endurance crater, flows of very fine dust can mimic water deposition, especially when you lay them over water weathered formations. It could be that any water weathering at that site occured a billion years before the dinosaurs, and the only recent flows are just silt.
If there is water, there will be water vapor. Send in the probe.
No secession language was dropped from the constitution? Can you spell Kurdistan?
*shrug* Of the US states that were formerly independent nations and absorbed into the United States of America by treaty, Texas was allowed a clause permitting it to back out of the deal and become an independent nation again. (It wasn't honored when push came to shove, but it was there.)
There is precedent for this, and it doesn't create any more (or less) danger of an independent Kurdistan than there was before a constitution was ratified. That token assuagement could keep Iraq together.
And, well, the Kurds and Shiites can steamroll over the Sunni representatives if they get together. Most of the current Sunni representation in Iraq is by the good graces of the interim government.
Actually, the theory has been advanced that apart from a few basic things like skin color and such, most of the differences are probably sexually selected, in other words, there are lots of redheads in Ireland because some proto-Celtic men really liked redheads, etc, and the differences among various ethnicities a matter of 'genetic fashion', so to speak.
Hmm... I wonder what traits would be sexually selected for on Mars?
Down here, our governor and legislature were publicly praising of the state gasoline tax last year. It kept the state's coffers full, bringing in fondly greeted revenue for yet another state budget surplus. We officially adore higher gas prices here in the great state of Louisiana.
After that announcement, the governor ran back to the capital in an effort to get the legislature to promote liquid methane terminals, solar power, hybrid vehicles, fluidized bed coal furnaces, carpooling, kids on ergonometers and any other gasoline conservation measure she could think of as fast as she could think of it.
Somehow, I don't think the folks over at the capital are expecting the gas tax windfall to last...
Pat Robertson spouting off again
*That guy really has a Wannabe King complex.
He's probably setting himself up for another run at the presidency. What do you think... 10% of the propular vote in 2008?
P.S.: The Venezuelan Catholic Archbishop recently stated Chavez is "possessed by the Devil" and "needs an exorcism." LOL!
If Pat Robertson's any indication, we could use some of those Venezuelan Archbishops here in the States!
I wonder how this stuff would work for balloon applications.
Hmm... Sheets of kevlar are already heat sealed onto sheets of PET for balloon gores. I see no reason this material couldn't be used instead of kevlar. This stuff could produce balloon fabric of the same strength at a fraction of the weight and thickness.
Cool! 8)
yup many more articles are listed on the spacetoday.net site
Putting it as the Nasa culture that did not change.
Who're the lily livered pansies now?
Great Britain has an amusing legislature _and_ monarch. But again, it functions because it’s a republic.
No it's not...
Yes, it is.
However, I take your point about the dangers of giving bureaucracy free reign.
The mere existence of a bureaucracy within a republic does not cancel out its status as a republic any more than does the existence of a military with a strict chain of command. However, a bureaucracy allowed to act unchecked by any other branch of government can cause a nation to cease functioning as a republic, just as a military coup can. Once the decisions of all other component oligarchies cease to matter, a nation is no longer operating as a republic.
Government bureaucracies should have checks and balances just like parliaments and courts do. Otherwise, they become a liability to the republic.
Logic of law is flawless. Conflict occurs because you are unwilling to recognise the authority of law, and are not interested in the equality that it pushes.
Sorry, you lost me at "logic of law."
Seriously, though, a functional system of law is no more perfectly egalitarian than a functional republic is. As an institution, Law exists primarily to maintain social order. It serves other purposes from time to time, but has no higher priority. Equal application is an afterthought.
*If you've had me in mind while making this comment: No.
No, I didn't have you in mind, Cindy. Kinda disappointing though. I wish someone here were guilty of that annoying tresspass so I could just blame it on some scapegoat and be done with it.
"I blame..." ( *lifts finger ominously and looks around for convenient pariah* )
If only.
As for Cobra's statement pertaining to achieving Godhood: I see where he's coming from with it, though my approach/viewpoint is differently angled.

Me too, although I can't get beyond the quite valid observation that a dog tick is more highly evolved than a dog. Just because we're already driving our own evolution doesn't mean we're going anywhere.
There seems to be an opinion floating around among non-religious people that religious people don't generally accept the fundamental claim of the evolution of species. I'd previously thought that charming opinion was limited only to fundamentalists. What an odd similarity between the two...
We clearly have a common ancestor with present day apes. Seventy percent of named species are parasites. The binding energy necessary to assemble complex organic molecules from scratch is also enough energy to completely denature them. We already have the power to control our own evolution (though Cobra's dreams of godhood might be slightly exaggerated). Evolution hasn't stopped. And I'm a religious person. These are all consistent statements.
Remember were talking about spiral 2 missions here. No longer than 14 days, or 1 lunar day. There isn't going to be time for building. Spiral 2 should be all about geology so we have a good idea of exactly what we have to work with.
I'm not sure that "spiral" should be used to describe an aeronautics program. :?
