Electricity Rationing Starting Monday In Tokyo

siddesu writes "Japanese officials are announcing a schedule for electricity blackouts to last from tomorrow until the end of April. Practically all suburbs of Tokyo will be affected by the blackouts. The 23 districts of central Tokyo seem to be exempt for the moment, but if supply is not sufficient, blackouts are possible. Electricity will be interrupted for about 3 hours a day in each area."

The whole system has been operating on the assumption that at least some of the power stations in the North will remain running. As it is, both those on the South and the North coast in the Eastern part are down, and the capacity is insufficient.

      Where it was planned to have transfer possible (e.g. The Shinkansen trains, for example, which can take power from both grids), there is less disruption. It is a sad example of bad planning due to historical accident.

    The US Navy's aircraft carriers and amphibious assault ships are an important part of relief efforts because they're mobile helicopter launching platforms. In a disaster, helicopters (and V-22 Ospreys) are the only good way to get around.

    “We currently have an aircraft carrier in Japan and another is on its way,” he said at the news conference. “We also have a ship en route to the Marianas Islands to assist as needed.”
    ...

    On his Twitter feed this morning, Noriyuki Shikata, deputy cabinet secretary for public relations and director of global communications at the Japanese prime minister's office, said the Japanese government requested U.S. forces in Japan to support efforts to rescue people and to provide oil and medical aid via the aircraft carrier USS Ronald Reagan, adding his thanks to the U.S. government.

    ... The aircraft carrier USS Ronald Reagan is now off the coast of Japan’s main island of Honshu and the USS Tortuga is expected to arrive today.

    According to reports, the Reagan is serving as place for Japanese helicopters to land and refuel. There are two escort ships with the Reagan and four more destroyers on the way to conduct search and rescue, according to reports.

    The Tortuga is loaded with two heavy lift MH-53 Sea Stallion helicopters. The USS Essex, an amphibious ship carrying a 31st Marine Expeditionary Unit is still a couple days away.

      Interesting proposal. They'd still have to strip out a lot if they went along with the plans to re-purpose a carrier from a Navy warship to something like a Peace Corps ship. And even then there would be some kind of restriction where the Navy would want to remain in charge because it's nuclear powered. Also my experience with that ship is that holds and such are far from automated, the cargo elevators (for things like food stores) aren't reliable - so you need like 50+ people to hump boxes down to the freezer for unrep ops and the such. (And that's just on one end of it.) I guess re-purposed magazines can hold a lot of dry-non-perishables and the ship can crank out a whole lot of potable water in the right conditions. Yet even under this role, it may take much more manpower for some operations than a purpose-built merchant marine type vessel. Obviously the only unique advantage is aircraft support in a large scale coastal SAR operation.

      The primary reason why CVN-65 is so expensive to operate is that it's the only carrier in it's class. It's a prototype that was made before the Eisenhower class ships were built. So for many things it doesn't conform to any standard as compared to all the other nuclear carriers. It's a one-of-a-kind that has more in common with the older WWII ships. And instead of two reactors made specifically for carriers, it has eight reactors that were originally designed to be in submarines at the time. (And if you're familiar enough with it, it seems like a kludge in comparison to the other super-carriers. Although it obviously also features more redundancy, under normal situations all that does is provide a much bigger and more complex operating overhead.) Despite being slightly bigger than the Eisenhower class ships, it has more space dedicated to engineering and a larger schedule of parts needed for logistical support than they do (a big part of the two yard periods I remember were about reducing and consolidating parts needed for support) and that's why it's expensive to run.

    It's an honor thing. It's not that Japan is being stubborn or just refusing to accept help for no good reason. For them, accepting help would be a display of weakness, which is heavily frowned upon. The Japanese highly value honor and humbleness. They don't like to ask others for things like that because it feels like taking charity. They see more honor in pulling themselves up by the bootstraps and overcoming through their own hard work and solidarity.

    What a load of bullshit honestly. There is already US search teams on the ground in Japan and US search aircraft carriers of the coast of Japan providing landing platforms and US airbases provided backup airfields for commercial flights that couldn't land. Hardly seems like not accepting aid to me.

    Remember that these are a people who, for many centuries, had a proud tradition of disemboweling themselves when they screwed up in order to restore their family's honor. That's pretty hardcore dedication to honor. So I don't figure their refusal for help as unkindness or stubbornness. It's just their tradition and ways, and I respect that, so I really don't feel offended at all at their saying "No thanks."

    Seppuku was a warrior tradition started around the 12th century which lasted for about 700 years. It probably started with a belief that the soul is contained in the stomach and was thus linked to religious practice and later evolved into an honorable way to serve out a death sentence. It's worth remembering though that at the height of their power and refinement in the Edo era, the warrior class never made up more than 10% of the population and even then were mostly bureaucrats and it's doubtful that every warrior believed in the practice of seppuku. It was only in the Meiji-era that it was elevated and romanticized as a form of traditional martial morality and national morality. In other words, 90% of the population never practiced it in the first place. Of the remaining 10% who made up the warrior class for many it was probably a gruesome and fearful but honorable way to serve out a death sentence and not something they would consider otherwise. Or in other words nobody anywhere near serious about sociology or at all knowledgeable about Japan uses a hugely romanticized and elevated in pop. culture custom to judge the actions of modern Japanese (except maybe to matters of support for the death sentence as a form of criminal punishment although even that is questionable. After all lots of other countries also support it). It's like using the extremes of Victorian upper class moral codes as a lens through which to judge the modern British.

    Here let me give you some more realistic reasons, which have actually been discussed in the Japanese media, as to why foreign aid workers aren't so helpful:

    • Language barriers make communication more difficult
    • No procedures in place to coordinate large foreign rescue contingents
    • Overlapping capacities make the rescue contingents less necessary. E.g. I can't see how teams of foreign nuclear engineers could have helped in Japan's reactor crisis. It was simply a matter of making appropriate responses to an evolving situation which the Japanese did. In regards to the coolant they did try and bring in some from America however the situation evolved too quickly.
    • In regards to the current power crisis I can't see how foreign aid would be any use at all. What are they going to do ship over power plants?

    My conclusion was that you would basically have to write off the whole state. Half the buildings would collapse, Dublin would be submerged, and there would be no infrastructure or competence to mount a rescue or recovery operation. Those not killed in the mass collapse of buildings, would die soon after from starvation and disease. The response of most of the population would be, naturally, to emigrate.

    But... this conclusion would probably hold for most other western states as well. We all remember Hurricane Katrina. The mantras of free market solutions and small government have left most western nations with barebones disaster response capabilities. A major Earthquake, Tsunami, Hurricane or firestorm in the wrong place could probably turn most western countries into Haiti within hours.

No skyscrapers collapsed and people actually got a warning that a Tsunami was coming, despite the nearness of the epicentre. The army was out collecting people the very next day.
