“Prayer Breakfast” Fallout: The Real Problem

Posted in Society on February 13, 2015 by max

Of course, the President was correct in citing historical crimes committed in the name of Christianity (and the response of the reactionaries was utterly predictable). But I don’t think his critique went nearly far enough. After all, no reasonable person today identifies with the acts of “bad guys” like slave owners, the KKK, or the Inquisition. But I think we are overdue for some scrutiny of the “good guys”. For example, consider the “Battle Hymn of the Republic” — it’s a wonderful, stirring march, but, oh my, the lyrics… They 100% identify the Union cause with the will of God, and anoint the Union army as His specific instrument. It’s almost as if it were a football team. My contention is that this kind of thinking constitutes the root of the evil, yet it is pervasive at all levels of society, from Cub Scouts to prep sports to the military academies to the White House (at least under certain administrations).

Any plausible concept of God would acknowledge that He is interested in individual souls, and therefore would not and could not take “sides”. Under examination, it is clear that the idea that God is on “my” side presupposes that “my” soul is of more concern to Him than the other’s soul — an implicit value judgment. In fact, it constitutes an act of bigotry. And every coach, every preacher and every politician who has ever claimed God’s endorsement for his cause has in effect committed a hate crime, by casting his adversaries as unworthy of God’s consideration.

That may sound like a pretty broad condemnation, but I don’t see a compelling counter-argument that doesn’t involve specific revelations of “God’s will”, which, of course, is the presumption that I am attacking. It is possible that one can only see these things clearly from an atheist perspective.

Don’t blame me — I’m just along for the ride

I occasionally have memorable, elaborate dream adventures. Sometimes thrilling, often seemingly profound. This is not one of those.

Last night’s dream was simply wacky. As I was preparing to go onstage as the drummer for a hip-hop ensemble (???), the manager was insisting that I put on blue suede cowboy boots, so I would match the rest of the band. I complained, “Nobody ever sees my feet”, but the porkpie-hatted vocalist, as he brushed past, muttered, “Oh, they will…” They next thing I knew, I was walking out into the audience with my wireless mike, leading them back onstage for the big finale, a sing-along to “Let It Be”. I got to solo on the verses.

I don’t know what the heck that was all about. But I woke up humming…

Are we a nation of idiots?

One might certainly come to that conclusion by observing the content of our cable channels. Channel after channel seem to consist entirely of “reality shows”. Now, I could go off at length on the venality and stupidity of the protagonists of these shows, and the sleaziness and phoniness of the situations, and how they are an insult to the intelligence of a senile wombat, but that is not what I feel like ranting about today. The current target of my scorn is the presentation of these shows. Out of every five minutes of running time, three minutes are spent regurgitating everything that happened up to the last commercial break, and one minute is devoted to “teasers” of upcoming events. At the end of a 22-minute episode, the viewer is “lucky” (if that is the correct word in this context) to have seen four or five minutes of actual unique narrative; the rest consisting of clips which were repeated two, three, four or even more times. So it’s not enough that the producers are targeting a demographic of undiscriminating, presumably-stoned couch potatoes with short attention spans, they have tailored their material specifically for undiscriminating, presumably-stoned couch potatoes with short attention spans and short-term memory loss. The really disturbing aspect is that this demographic is apparently large enough to be worth targeting — chew on that for awhile.

Free Idea #1: Saving water

Posted in Environment, Free Ideas on April 1, 2011 by max

I’m adding a new category of posts, titled “Free Ideas”. These are brainstorms that might actually have some real-world value, but that I am not in a position to do anything with. Feel free to run with it…

The issue

Given the plethora of well-documented world-wide issues with adequate fresh water, it occurs to me that it is practically obscene to be using clean, potable water for the purpose of whisking bodily wastes into the sewage system; that is, flushing the toilet. My back-of-the-envelope calculation suggests that the US wastes 4.8 billion gallons of water per day in this manner (partial statistics here). You could save a lot of salmon with that kind of flow. Low-flow toilets are not a complete solution, since each flush still wastes 1.6 gallons; moreover, in the city of San Francisco, they have a problem with inadequate volume of liquid to move the wastes through the sewers, which were designed for older high-volume toilets (yeah, I know… TMI).

The solution

My idea is to revise the building code to require the use of gray water for flushing toilets. Gray water is recycled water; for example, recovered from the shower or bathtub. This water is already ticketed to go down the drain, and you can’t really argue that a little shampoo residue is going to hurt your toilet bowl (a filter could be used to catch the gross stuff like hair). In drought situations, a lot of people already capture shower water in a bucket and it it to flush the toilet. My idea is to institutionalize this with a standard design of a simple plumbing system that would perform the same function, and be completely transparent to the user.

A typical shower using a modern 2.5 gallon-per-minute shower head would provide 7 or 8 gallons of water for this system. For comparison, a modern low-flush toilet uses 1.6 gallons per flush. So for each person taking a shower in your household, you would get five “free” flushes per day. It would also be logical for the system to utilize water from the bathroom sink and kitchen sink (assuming no garbage disposal), and possibly the dishwasher and washing machine. Gray water irrigation systems don’t use washing machine output because of the possibility of fecal contamination from diapers (more TMI), but that”s not a problem as this water would wind up in the sewer anyway.

As I see it, this system would need a holding tank (probably about the size of the typical water heater), and a system of valves that would automatically enable flushing with clean water if the tank happened to be empty, and that would route excess gray water down the drain when the tank was full. It might also need some kind of pump or siphon system depending on the relative levels of the plumbing fixtures, and a cleanable or replaceable filter. Some genius could probably design a kit that could be used to retrofit existing residences.

Fukushima: in hindsight, could the crisis have been prevented?

Today, with increasing concerns about radiation leaks, and very little progress in stabilizing the reactor cores, the situation seems to be deteriorating. I am wondering, however, if some of the radiation figures we are seeing are really major increases, or just a result of better monitoring — more instruments in the field, and more systematic deployment. In the early days, the workers were too busy to spend a lot of time on monitoring, and most detectors were offline. Clearly, there is a buildup of contaminated water in the lower levels of the reactor buildings, and the nearby spillover trench; but this can only be expected, considering how indiscriminately they have been using whatever water was available to keep the fuel rod temperatures more or less under control. It also seems inevitable that a lot of this contaminated runoff will reach the ocean, as it is already within 50-60 meters. At present the primary radioactive material seems to be iodine 131, which has a short half-life of only eight days. There is a report of trace amounts of plutonium, presumably from reactor 3, but it is not clear how it might have escaped. The stabilization of the reactor cores remains the first priority, so it is likely that a certain amount of radiation release will continue, as an unavoidable side effect of these efforts.

In an ideal situation, we would not have radiation leaks at all, it goes without saying. So, looking backward, is there any way this ongoing near-catastrophe could have been prevented? I have to say “yes” — both before the fact, at the plant design level; and after the fact, in the early response stages. I am going to save the discussion of the former for another time, and address the actions of the plant managers in the first days after the quake.

What happened on March 11

According to the NOVA special, the Fukushima reactors automatically went into shutdown when the quake hit. This was apparently a deliberate safety measure (whether it was a good idea is a question I will explore later). While it takes a long time for the reactor cores to actually cool, at this point they were no longer generating electricity. Diesel-powered generators automatically kicked in to provide power for lighting, controls, and the crucial cooling pumps. It is not clear whether the plant was cut off from the national electric grid by the effects of the earthquake itself, or by the later tsunami, but for the purposes of this reconstruction I will assume the connection was knocked out by the earthquake. At any rate, for this brief period between the earthquake and tsunami, the situation was under control.

We all know what happened next — the tsunami flooded the diesel generators, which cut off all power to the plant. It isn’t clear whether the generators were damaged, completely destroyed, or merely quit due to temporary submersion, but the result was the same. The plant shifted to emergency battery power, but this was sufficient for only eight hours of operation. By approximately midnight, the critical function of pumping cool water through the reactor vessels to cool the fuel rods had stopped, leading to elevated core temperatures and the possibility of meltdown. Most reports have focused on this failure (for good reason), but I would like to call attention to another malfunction that I think actually initiated the downward spiral: the secondary containment structures also had a cooling and ventilation system, which, of course, was also without power.

The purpose of the secondary containment was to capture any releases from the reactor vessel in case of malfunction; therefore it was equipped with a sophisticated ventilation and filtering system. The filters were designed to capture any radioactive particles, and to harmlessly vent any hydrogen gas buildup. Highly-explosive hydrogen gas is a known byproduct of overheated fuel rods. The problem was that, with no electric power, they had a situation with both overheating fuel rods and a non-functioning ventilation system (I have to say this certainly looks like a design flaw).

As the fuel rod temperatures increased, the cooling water in the reactors turned to steam, increasing the pressure in the vessels. In order to prevent the reactor vessels from bursting (which would have been a first-class calamity), the plant managers were forced to release steam into the secondary containment structures. This steam contained both radioactive contaminants, and hydrogen gas.

March 12: fatal inaction?

This was the situation in the early morning hours of March 12. The site personnel had probably been on the job for 12-18 hours; transportation and communications were disrupted throughout the region; many people were probably in a state of psychological shock. TEPCO headquarters in Tokyo probably had very little understanding of the situation at the plant, and the government oversight agencies even less. Workers were preoccupied with cooling the reactor cores — I believe they were in the process of introducing seawater to replace the water that had boiled off. In the confusion, the issue of hydrogen buildup seems to have been overlooked. Then, the roof blew off Reactor Building #1.

For all the reasons mentioned above, I can scarcely blame anyone for this particular disaster. As I said, it seems to have been a secondary result of a faulty design that allowed two sequential safety systems to fail for the same cause. But you could also argue that this hydrogen explosion should have been anticipated; after all, they knew they were venting the core, and the system had been designed with the understanding that this venting could release explosive hydrogen. Regardless, it seems inexcusable that the explosion in reactor 1 was followed by explosions in Building 4 (the same day), Building 3 (March 14) and Building 2 (March 15). Given that the possibility of a hydrogen explosion was well-known, not to mention conclusively demonstrated on March 12, it seems to me that some kind of effort should have been undertaken to vent the secondary containment buildings; either by manually opening roof vents, or even sending work crews to remove sections of roof or walls if necessary.

I am harping on this point because, in hindsight, these hydrogen explosions are the primary reason the reactors have not been stabilized, and why there are continuing problems with cooling and with radiation releases. Look at this video of one of the damaged reactor buildings — try to imagine how difficult it must be for workers trying to reestablish lighting, control and cooling systems in this apocalyptic, radioactive landscape of steaming, twisted metal. I would go so far as to say that if it weren’t for the damage caused by these explosions, the reactors would all be under control by this time (as are reactors 5 and 6, which did not suffer explosions).

Tough choices

One possible reason why no attempt was made to ventilate the secondary containment buildings was that this would release a certain amount of radiation. In the immediate aftermath of the earthquake/tsunami, it is understandable that TEPCO managers would be reluctant to do so; in fact, in normal circumstances, a deliberate release would be almost unthinkable, given the sensitivity to any mention of radioactivity that is understandably widespread in the Japanese populace. But my contention is that a deliberate release at this point (to be more precise, it would have had to have been an ongoing release over a week or more) could have prevented the enormous destruction of infrastructure which is currently handicapping the recovery efforts and endangering the workers; infrastructure that, ironically, had survived the earthquake and tsunami intact.

Fukushima: the struggle continues

Posted in Environment on March 26, 2011 by max

The effort to contain the damage at the Fukushima Daiichi nuclear plant underwent a setback yesterday, when high levels of radiation forced workers to vacate reactor building #3. Two workers suffered radiation burns from wading through contaminated water; reportedly, the workers were not wearing protective boots. The BBC reported that turbine halls at reactors 1 and 3 had radiation levels 10,000 times higher than normal. Japan’s Nuclear Safety Agency denied that the reactor cores were breached, but admitted that some sort of leakage may have occurred.

Levels of radiation measured in sea water 300m off the coast were eight times higher than a week ago. An NSA spokesman stated that sea life should not be affected, as the radioactive iodine isotope responsible has a half-life of only eight days, but many Japanese remain concerned. It is not clear whether the radioactive material was swept to sea as runoff, or was borne by offshore winds.

Considering the amount of water that workers have been spraying around the plant over the last week in an attempt to keep temperatures in the spent fuel rod pools under control, elevated radiation levels in runoff would hardly be surprising. This could also explain the concentration of radioactive contaminants at low points in the reactor buildings. It is not necessary to presume a breach in the core containment. However, so long as the fuel rod temperatures remain above normal, the danger of meltdown and core breach remains. It is critical that technicians are able to keep working in the reactor buildings to bring control and cooling systems back online. This is the major concern raised by yesterday’s developments: if workers are unable to safely approach the reactor buildings, the status of the damaged reactors, already unstable,  will rapidly deteriorate. Hopefully, as in the case of previous radiation alerts, the workers will be able to resume their valiant efforts after a brief hiatus.

Japan nuclear plant: Radioactivity rises in sea nearby

Fukushima update

Posted in Environment on March 23, 2011 by max

Here is an updated status from BBC News:

  • Reactor 1: Damage to the core from cooling problems. Building holed by gas explosion. Power lines attached.
  • Reactor 2: Damage to the core from cooling problems. Building holed by gas blast; containment damage suspected. Power lines attached.
  • Reactor 3: Damage to the core from cooling problems. Building holed by gas blast; containment damage possible. Spent fuel pond partly refilled with water after running low. Power lines attached.
  • Reactor 4: Reactor shut down prior to earthquake. Fires and explosion in spent fuel pond; water level partly restored. Power lines attached.
  • Reactors 5 & 6: Reactors shut down. Temperature of spent fuel pools now lowered after rising high. Power lines attached.

Note that power lines have been hooked up to each building. In reactors 5 and 6, they are reported to have successfully brought the cooling systems online. The have brought up power and lighting in the control room for reactor 3, and are planning to try to start the cooling pumps tomorrow.

All of this is good news. The fact that they have accomplished this much is an indication that radiation in the immediate area is not increasing, and gives hope that progress will continue at this pace. It may still be weeks or even months before all of the reactors are stabilized, due to the physical damage to systems and structures; but I would go so far as to say that the possibility of a core meltdown is greatly diminished. Good job.
