Weekend linkage

Here's some weekend reading/listening for you.  I really should do this more often so you can see what I'm looking at:

Saudi Arabia going ahead with building 16 nukes:  Even after Fukushima they have decided to go ahead.

Why didn't Fukushima #2 (Daini) meltdown as well?  Very interesting ideas as to why the second power plant complex did not have the problems #1 (Daiichi) experienced.  It may be merely luck and location or it may be the newer powerplant designs.

Nuclear regulatory issues.  Obviously a very large problem as a 'captured' regulator can allow serious problems to develop.

Carmen Reinhart discusses financial repression in developed economies.  If you think short term rates will rise shortly I think you are wrong.  Financial repression is a broad term but a clear example is keeping short term interest rates below inflation (a negative real rate) This slowly inflates away the debt problem.  Will America and Western Europe be able to pull it off?

China's empty cities, again -- A more recent article on Ordos' empty new city

China's debt writeoffs are just the beginning -- The opera of excessive credit growth and very lax underwriting standards is starting to get to the good part.

Japan Nuclear Update: Fear and Loathing about Fukushima

It hasn't taken very long for the charlatans and plain fear mongers to try to capitalize on the situation in Japan. I recently saw a banner ad on my web site for a company shilling a supplement to prevent radiation injury to Americans. I am not going to link to the company and give them free publicity.



To be very clear:
YOU ARE IN NO DANGER IF YOU LIVE IN ALASKA, HAWAII OR THE CONTINENTAL US.
The EPA agrees with me without using all caps.
professor from Berkeley agrees with me.

Those who have a memory longer than a year may recall two nuclear weapons detonated OVER Japan a few decades ago. The amount of nuclear radiation emitted from those events were several orders of magnitude higher than the current situation yet we didn't have anyone dying in America did we?

This chart from http://xkcd.com/radiation/ has been floating about showing the relative levels of radiation and I think one should really take a look at it to put some of the news reports in context.  One problem is our instruments are so sensitive that its very possible in America to detect the slightly elevated levels of radiation that have made it to our shores.  Then again, getting on an airplane would provide a much higher dose but that doesn't seem to be mentioned at the same time the TV breathlessly tells you the clouds of nuclear radiation are coming this way.

Plutonium:
There's been reports plutonium has been found on the grounds of the Fukushima power plants and we should all hit the panic button  Plutonium is a natural by product of the normal fission cycle which occurs in a power plant. What they didn't mention in the first reports is the scale of the plutonium concentration and that matters a lot. For some sanity I suggest you listen to this interview:

Tepco came out with some clarification of the Plutonium and it's not something to worry about

Finding people in Japan:
The red cross has another site for finding people in Japan here:
http://www.familylinks.icrc.org/web/doc/siterfl0.nsf/htmlall/familylinks-japon-eng
I mentioned another site run by Google a couple days ago.

Predictions for cleanup taking 30 years:
I ran across a Bloomberg article predicting it will take 30 years and billions to clean this mess up. I link to it so we can see how accurate they are. I find it odd to make such predictions when the smoke hasn't even settled.

There's an interesting presentation by Arevea floating around which appears to give a good timeline of what has happened. Of course this is a theory regarding the damage of the cooling torus but it does look like a possible reason for the elevated radiation readings in the water.

I'm not trying to sugar coat the issue in Japan which is still volatile and dangerous but please respond to any positive or negative news reports with a healthy dose of skepticism.

An amazing rescue story from Japan

The tragic stories coming from Japan keep piling up and the death toll climbs every day as the Japanese try to dig themselves out of the rubble.   The humanitarian challenge of caring for a couple hundred thousand homeless is straining even the organized Japanese.

Amongst the despair and rubble there are amazing stories of bravery and determination emerging.

Here is one of them.
Hideaki Akaiwa escaped the earthquake and tsunami, but after being unable to find his wife, scrounged up some SCUBA gear and went back into the waters to find his wife! He succeeded and later pulled the same technique to find his mother.  A somewhat embellished but great read of the story goes something like this (from Badassoftheweek 03/18/11)
Regardless of how he came across this equipment (borrowing, stealing, buying, beating up a Yakuza SCUBA diving demolitions expert, etc.) Hideaki threw on his underwater survival gear, rushed into the goddamned tsunami, and dove beneath the rushing waves, determined to rescue his wife or die trying. I'm not exactly sure whether or not the dude even knew how to operate SCUBA equipment, but according to one version of his story he met his wife while he was surfing (which is awesome, by the way), so it doesn't seem like that much of a stretch to say that he already had a little experience SCUBA diving under a more controlled situation. Of course, even if this dude didn't know how to work the gear I'm certain that wouldn't have stopped him either – Hideaki wasn't going to let a pair of soul-crushing natural disasters deter him from doing awesome shit and saving his family. He dove down into the water, completely submerged in the freezing cold, pitch black rushing current on all sides, and started swimming through the underwater ruins of his former hometown.
Surrounded by incredible hazards on all sides, ranging from obscene currents capable of dislodging houses from their moorings, sharp twisted metal that could easily have punctured his oxygen line (at best) or impaled him (at worst), and with giant fucking cars careening through the water like toys, he pressed on. Past broken glass, past destroyed houses, past downed power lines arcing with electrical current, through undertow that could have dragged him out to sea never to be heard from again, he searched.
Hideaki maintained his composure and navigated his way through the submerged city, finally tracking down his old house. He quickly swam through to find his totally-freaked-out wife, alone and stranded on the upper level of their house, barely keeping her head above water. He grabbed her tight, and presumably sharing his rebreather with her, dragged her out of the wreckage to safety. She survived.
