First, the guy who resigned said his specific worries had been addressed. So what difference does it make?
Cooling ponds are ponds (the kind frogs live in, but warmer) that heated water released from the plant are discharged into to allow the water to cool rather than being discharged into a river, lake or ocean with a big thermal impact on that body of water. The correct term for this case is spent fuel pool. If you wish for your opinions to be taken seriously, you have to be able to talk about relevant issues using appropriate terminology.
No fissile materialis stored on top of the building. Spent fuel pools are low, and the material is essentially the same as is in the reactor, minus a bit of U235 and plus a bit of fission products, including plutonium. These tubes would be reprocessed with only a fraction of the material being buried. The USA is not 400 years old. Active cooling is not required on spent fuel pools, but the rods must remain covered so the water level must be maintained. Swimming is not allowed.
Loss of Coolant has occurred already at three reactors. LOCA is a scenario that includes all kinds of possible scenarios like brake failure on a vehicle, if you are parked on a flat surface there is no consequence, if you are driving a loaded gasoline carrier going 80 mph downhill toward a cliff the consequences are a bit greater. Pronouncements such as "exactly one hydrogen or steam explosion away" are preposterous - radioactive release could occur without either, but both might occur without radioactive release.
You are grossly mislead, but your fundamental concerns are valid. It is conceivable that a significant release of radioactive material will occur, but much of what you have said is utter nonsense.
I am very circumspect about any article without citations. The first article has none. I am not dismissing it out of hand, but I don't go for hearsay from a source that I have never heard of. Here is substantially the same information presented authoritatively.
The second article addresses earthquake design basis, there is nothing to suggest at this point that the plant sustained any failures due to the seismic event per se. Japan's Nuclear and Industrial Safety Agency analysis of the safety of the plants appears to be correct but, in hindsight, (like the warnings) too limited in scope.
I believe I understand the situation, and I stand by my original conclusion: For a spherical shell (the reduced volume of the ocean) I=2/3mr^2 for a point (the reservoir) I=mr^2 the mass put into the reservoir is the same as the mass taken from the ocean so if the radius of rotation of the reservoir is greater than 2/3 the effect is an increase in I. So acos(2/3)= break even point, assuming the reservoir is at the original sea level and not higher. So any reservoirs below 48 degrees slow the earth. As a point of reference, the US-Canada border is at 49 degrees and only a small part of China is above 48 degrees. Since land masses affect where the water would come from latitude-wise the math is not exact, but I would expect that to alter the position by only a fraction of a degree. The top nine man made lakes slow the earth's rotation based on their volume and latitude and ignoring altitude which would further increase the effect. Knowing how much of the water in each lake is impounded due to the damn and what portion is natural would be required to precisely determine the effect, but I expect it would further increase the slowdown.
List of reservoirs by volume
1. Lake Kariba (180 km3 or 43 cu mi; Zimbabwe, Zambia)
2. Bratsk Reservoir (169 km3 or 41 cu mi; Russia)
3. Lake Nasser (157 km3 or 38 cu mi; Egypt, Sudan)
4. Lake Volta (148 km3 or 36 cu mi; Ghana)
5. Manicouagan Reservoir (142 km3 or 34 cu mi; Canada)
6. Lake Guri (135 km3 or 32 cu mi; Venezuela)
7. Williston Lake (74 km3 or 18 cu mi; Canada)
8. Krasnoyarsk Reservoir (73 km3 or 18 cu mi; Russia)
Only problem is Chao is wrong about the direction of the impact. Raising water increases the mass moment of inertia slowing the earth's rotation except at very high latitudes. He did not do a rigorous analysis. Melting icecaps would also slow rotation.
Don't forget roadsigns. They are art! Paint applied to a flat surface for other than the purpose of protecting that surface is the very definition of art.
The fresco of the sistine chapel is paint applied to wet stucco in a magnificent edifice. Games are a painted turd in a beige box; the turd being the operating system.
On that basis paintings of dogs playing poker are near the apex of man's creative expression. The prints of this series are among the most ubiquitous. These paintings have a certain technical merit, but they don't have an enduring aesthetic quality and neither do games.
The vast majority of Economists are always experts in their predictions, but wrong in hindsight. They, not lawyers, are the cause of our current litigious society; they want to settle to reduce exposure while a lawyer would happily fight to the bitter end rather than pay a troll. They are the ones who came up with derivatives and the financial instruments that have resulted in our current economic woes. The "informed opinion" that results from "an education in economics" is too infrequently an intelligent one.
Gabe Newell said, ""Price changes in the retail world don't allow for much freedom. Steam and other services offer flexability. In fact, users apparently respond to pricing discounts within five minutes." And what the psychologist really said was that, "He suggested one in 25 users that buy Left 4 Dead get another Valve game for free." Those statements sounds like an "impulse incentive" (your words) to the customer.
Designing all plants to the same standard is more economical than designing each plant to the site specific criteria. The French have demonstrated this, even going to relatively extreme requirements the savings should be substantial with operating and maintenance procedures identical training and personnel costs would be reduced. In the US each plant is unique in almost all of these areas. The cooling failure is due to the backup diesel generators being swamped if the media reports are correct. It is a problem that could not occur at most US plants, but the small reactors in the article might be a solution to that problem.
I think your pronouncement that the situation proves nuclear power is safe may be premature. I can't agree with you until the situation is stabilized. Unit 4 is reported to have sustained more damage than the other units, and there is a remote possibility that containment may have been compromised.
I am well aware that that the ground motion was far beyond the design parameters. At TMI, commercial grade equipment performed tasks far beyond what anyone would have expected too, but to assume that that will happen in the future is simply not prudent. Design assumptions have to be made for each plant and we keep finding unanticipated surprises like 100 year flood plains that flood every 5 years and now Tsunamis. An example of an unanticipated issue, how vulnerable are nuclear plants to EMP? EMP can be generated without a nuclear blast. I know that the plants rely mostly on 50 year old technology that is far less vulnerable than today's solid state electronics but this is a threat that is not part of the design equation of US plants; I am not speculating, I have worked with the equipment qualifications for nuclear plants for 25 years.
Back on topic: A couple of the 4S generators mentioned in the article might have kept the pumps running at Fukushima averting any loss or safety issue. Standby diesel generators, even eliminating being swamped by a big wave, are one the weakest links in the safe shutdown scenarios.
Valve hired a psychologist to look at trends regarding pricing vs. sales, and he didn't seem to think that this was some sort of discount impulse kicking in.
Sounds like his opinion to me, one that runs contrary to the marketing training I have received. How about a citation?
You are ignoring the fact that if Valve were to lower prices across the board these increases in sales would be unlikely. These increases sales are not due to reduced prices , they are due to discounts. There is a strong psychological motivation to buy an item at a perceived discount that does not exist with an item priced at a fair price in the first place.
A low voltage cut-off costs less, it turns off the GPS when the battery hits 10.4 volts which is enough to start the car. It works with covered parking.
The picture of her was taken in a public place where she had no expectation of privacy. The personal gain argument fails since a private investigator could take a picture of her and be paid by the husband; the picture would be admissible in court. Even if she could establish that the poster had no right to publish the picture, that would not mean that the picture could not be used by the court since it was not taken illegally. Otherwise every defense team would publish the evidentiary pictures against their client thus violating copyright and excluding them from the trial.
The Playboy pictures are copyrighted so you may not use the pictures except within the confines of "fair use".
Just why would any court want less evidence? The judge & jury need information to base their decision upon. The more, the better.
In general your statement is true, but the exceptions are important. Had the prosecution in the Nicole Simpson murder case restricted their case to the strongest evidence (motive, opportunity, the best of the blood evidence), O.J. Simpson would probably been convicted. When one "expert witness" claims the state's evidence is wrong, juries tend to take it with a grain of salt, but ten "expert witnesses" represent reasonable doubt.

Whoosh!
Gyroscopes would be far more effective.

When I married I made substantially the same arguments. She wanted a diamond solitaire or nothing, it should have been a deal breaker, sigh.
Wait, AC RTFA? I thought daylight saving was ahead an hour not nineteen days.
Doesn't that make it an inconspicuous means of clearing one's history.
