Photo-voltaic Impasse

Might have been broken.

Photovoltaic (PV) efficiency is a significant problem for today’s commercial solar panels, which can collect only a theoretical maximum of about 30 percent of available light. Now, a team that includes a University of Missouri engineer is developing a flexible solar film that can theoretically capture more than 90 percent of available light. Prototypes could be produced within the next five years.

Patrick Pinhero, an associate professor in the MU Chemical Engineering Department, says energy generated using traditional photovoltaic methods of solar collection is inefficient and neglects much of the available solar electromagnetic (sunlight) spectrum. The device the team is developing — essentially a thin, moldable sheet of small antennas called nantenna — is designed to harvest industrial waste heat and convert it into usable electricity. Their ambition is to extend this concept to direct solar facing nantenna devices capable of collecting energy broadly from the near infrared to the optical regions of the solar spectrum.

90% is much more like it. High-speed electrical circuitry. Inexpensive manufacturing processes. This is not being saved by technology so much as using engineering to break the problem down into manageable fragments until it’s no longer a problem and more of way to do what we want – harvest as much energy as possible for the sun.

Moving on to renewable energy sources can be done – and need not been seen or thought of a desperate last gasp/final hope but the natural of progression of technology and its uses that our subservience to fossil energy sources has for so long stymied. Departments of Energy whose first loyalty is to oil and gas industries will not provide the necessary R & D investments in replacing the same. This kind of research takes a lot of money, time and expertise – but the payoffs will be enormous. I’m looking at you, coal, in the rear view mirror.

Harvey Milk-iversary

Sunday would have been the 81st birthday of the first openly gay man elected to public service in the U.S. Cali Governor Jerry Brown:

Gov. Jerry Brown declared Sunday as the state’s second ever “Harvey Milk Day,” saying the slain politician’s “life was cut short far too soon, but his legacy of hope, tolerance, and equality lives on.”

Sunday would have been Milk’s 81st birthday. The San Francisco supervisor and gay rights leader was shot and killed, as was Mayor George Moscone, by another supervisor in 1978.

The Big Muddy

100287_nasa

From Mark Twain’s The Body of the Nation, Harper’s 1863:

It is a remarkable river in this:  that instead of widening toward its mouth,
it grows narrower; grows narrower and deeper.  From the junction of the Ohio
to a point half way down to the sea, the width averages a mile in high water:
thence to the sea the width steadily diminishes, until, at the ‘Passes,’ above
the mouth, it is but little over half a mile.  At the junction of the Ohio
the Mississippi’s depth is eighty-seven feet; the depth increases gradually,
reaching one hundred and twenty-nine just above the mouth.

The difference in rise and fall is also remarkable–not in the upper,
but in the lower river.  The rise is tolerably uniform down to Natchez
(three hundred and sixty miles above the mouth)–about fifty feet.
But at Bayou La Fourche the river rises only twenty-four feet;
at New Orleans only fifteen, and just above the mouth only two
and one half.

An article in the New Orleans ‘Times-Democrat,’ based upon reports
of able engineers, states that the river annually empties four hundred
and six million tons of mud into the Gulf of Mexico–which brings to mind
Captain Marryat’s rude name for the Mississippi–‘the Great Sewer.’
This mud, solidified, would make a mass a mile square and two hundred
and forty-one feet high.

The mud deposit gradually extends the land–but only gradually;
it has extended it not quite a third of a mile in the two hundred
years which have elapsed since the river took its place in history.
The belief of the scientific people is, that the mouth used to be
at Baton Rouge, where the hills cease, and that the two hundred
miles of land between there and the Gulf was built by the river.
This gives us the age of that piece of country, without any
trouble at all–one hundred and twenty thousand years.
Yet it is much the youthfullest batch of country that lies
around there anywhere.

The Mississippi is remarkable in still another way–
its disposition to make prodigious jumps by cutting through narrow
necks of land, and thus straightening and shortening itself.
More than once it has shortened itself thirty miles at
a single jump!  These cut-offs have had curious effects:
they have thrown several river towns out into the rural districts,
and built up sand bars and forests in front of them.
The town of Delta used to be three miles below Vicksburg:
a recent cutoff has radically changed the position, and Delta is now TWO
MILES ABOVE Vicksburg.

Shades of Purple

Now this is the kind of Iraqi issue I, for one, am glad to fret over:

Baghdad has weathered invasion, occupation, sectarian warfare and suicide bombers. But the latest scourge, tastelessness, may prove the toughest to overcome.

Iraqi artists and architecture critics who shudder at each new pastel building blame a range of factors for Baghdad’s slide into tackiness: including corruption and government ineptitude, as well as everyday Iraqis who are trying to banish their grim past and are unaccustomed to having the freedom to choose any color they want.

God bless ’em. Welcome to the modern world, Iraqis. But for my money, this is the pull quote:

“Right now, when I have an exhibition at my gallery nobody comes from the government, only the art students and other artists,” Mr. Sabti said. “Taking care of the look of the city has stopped because the people who have come to power were living in villages with animals. So how did they develop their taste?”

If you guys figure anything out, do tell.

1961

With all the highways and Zimmerman’s birthday coming up and all, seems like a good time for some Fanon. This time through the  [translated] words of J.P. Sartre. If you haven’t read Franz Fanon’s The Wretched of the Earth (Les Damnes de le Terre, 1961), you should. This is from Sartre’s preface:

NOT so very long ago, the earth numbered two thousand million inhabitants: five hundred million men, and one thousand five hundred million natives. The former had the Word; the others had the use of it. Between the two there were hired kinglets, overlords and a bourgeoisie, sham from beginning to end, which served as go-betweens. In the colonies the truth stood naked, but the citizens of the mother country preferred it with clothes on: the native had to love them, something in the way mothers are loved. The European élite undertook to manufacture a native élite. They picked out promising adolescents; they branded them, as with a red-hot iron, with the principles of western culture, they stuffed their mouths full with high-sounding phrases, grand glutinous words that stuck to the teeth. After a short stay in the mother country they were sent home, whitewashed. These walking lies had nothing left to say to their brothers; they only echoed. From Paris, from London, from Amsterdam we would utter the words ‘Parthenon! Brotherhood!’ and somewhere in Africa or Asia lips would open … thenon! … therhood!’ It was the golden age.

It came to an end; the mouths opened by themselves; the yellow and black voices still spoke of our humanism but only to reproach us with our inhumanity. We listened without displeasure to these polite statements of resentment, at first with proud amazement. What? They are able to talk by themselves? Just look at what we have made of them! We did not doubt but that they would accept our ideals, since they accused us of not being faithful to them. Then, indeed, Europe could believe in her mission; she had hellenized the Asians; she had created a new breed, the Graeco-Latin Negroes. We might add, quite between ourselves, as men of the world: ‘After all, let them bawl their heads off, it relieves their feelings; dogs that bark don’t bite.’

A new generation came on the scene, which changed the issue. With unbelievable patience, its writers and poets tried to explain to us that our values and the true facts of their lives did not hang together, and that they could neither reject them completely nor yet assimilate them. By and large, what they were saying was this: ‘You are making us into monstrosities; your humanism claims we are at one with the rest of humanity but your racist methods set us apart.’ Very much at our ease, we listened to them all; colonial administrators are not paid to read Hegel, and for that matter they do not read much of him, but they do not need a philosopher to tell them that uneasy consciences are caught up in their own contradictions. They will not get anywhere; so, let us perpetuate their discomfort; nothing will come of it but talk. If they were, the experts told us, asking for anything at all precise in their wailing, it would be integration. Of course, there is no question of granting that; the system, which depends on over-exploitation, as you know, would be ruined. But it’s enough to hold the carrot in front of their noses, they’ll gallop all right. As to a revolt, we need not worry at all; what native in his senses would go off to massacre the fair sons of Europe simply to become European as they are? In short, we encouraged these disconsolate spirits and thought it not a bad idea for once to award the Prix Goncourt to a Negro. That was before ’39.

1961. Listen: ‘Let us waste no time in sterile litanies and nauseating mimicry. Leave this Europe where they are never done talking of Man, yet murder men everywhere they find them, at the corner of every one of their own streets, in all the corners of the globe. For centuries they have stifled almost the whole of humanity in the name of a so-called spiritual experience.’ The tone is new. Who dares to speak thus? It is an African, a man from the Third World, an ex-‘native’. He adds: ‘Europe now lives at such a mad, reckless pace that she is running headlong into the abyss; we would do well to keep away from it.’ In other words, she’s done for. A truth which is not pleasant to state but of which we are all convinced, are we not, fellow-Europeans, in the marrow of our bones?

We must however make one reservation. When a Frenchman, for example, says to other Frenchmen ‘The country is done for’ — which has happened, I should think, almost every day since 1930 — it is emotional talk; burning with love and fury, the speaker includes himself with his fellow-countrymen. And then, usually, he adds ‘Unless …’ His meaning is clear; no more mistakes must be made; if his instructions are not carried out to the letter, then and only then will the country go to pieces. In short, it is a threat followed by a piece of advice and these remarks are so much the less shocking in that they spring from a national intersubjectivity. But on the contrary when Fanon says of Europe that she is rushing to her doom, far from sounding the alarm he is merely setting out a diagnosis. This doctor neither claims that she is a hopeless case — miracles have been known to exist — nor does he give her the means to cure herself. He certifies that she is dying, on external evidence, founded on symptoms that he can observe. As to curing her, no; he has other things to think about; he does not give a damn whether she lives or dies. Because of this, his book is scandalous. And if you murmur, jokingly embarrassed, ‘He has it in for us!’ the true nature of the scandal escapes you; for Fanon has nothing in for you at all; his work — red-hot for some — in what concerns you is as cold as ice; he speaks of you often, never to you. The black Goncourts and the yellow Nobels are finished; the days of colonized laureats are over. An ex-native French-speaking, bends that language to new requirements, makes use of it, and speaks to the colonized only: ‘Natives of an under-developed countries, unite!’ What a downfall! For the fathers, we alone were the speakers; the sons no longer even consider us as valid intermediaries: we are the objects of their speeches. Of course, Fanon mentions in passing our well-known crimes: Sétif, Hanoi, Madagascar: but he does not waste his time in condemning them; he uses them. If he demonstrates the tactics of colonialism, the complex play of relations which unite and oppose the colonists to the people of the mother country, it is for his brothers; his aim is to teach them to beat us at our own game.

The Wearing of the Funny Hat

The Vatican is shrill.

We call on all people and nations to recognise the serious and potentially irreversible impacts of global warming caused by the anthropogenic emissions of greenhouse gases and other pollutants, and by changes in forests, wetlands, grasslands, and other land uses. We appeal to all nations to develop and implement, without delay, effective and fair policies to reduce the causes and impacts of climate change on communities and ecosystems, including mountain glaciers and their watersheds, aware that we all live in the same home. By acting now, in the spirit of common but differentiated responsibility, we accept our duty to one another and to the stewardship of a planet blessed with the gift of life. We are committed to ensuring that all inhabitants of this planet receive their daily bread, fresh air to breathe and clean water to drink as we are aware that, if we want justice and peace, we must protect the habitat that sustains us. The believers among us ask God to grant us this wish.

So there’s that. The Pontiff makes all kinds of pronouncements all the time and is also against birth control of any kind, so I’m not sure what kind of impact this will have. And besides, I don’t endorse his/their views on all things just because he agrees with me on this one thing.

But you do wonder about the role this kind of endorsement has on the low-lying populace. JR calls it the ‘pray for science’ approach.

Flooded Threads

0503-mississippi-river-flooding-memphis_full_600

This is a good example of why the green issue is so complex, viz our modern ways and means, and corrections to it so complicated.

An emergency procedure intended to prevent the Mississippi and Ohio Rivers from flooding several river towns appears to be working Tuesday, as river levels have fallen more than a foot. However, water levels are rising as far south as Memphis, Tenn., where heavy rainfall could contribute to a river crest of 48 feet next Tuesday.

Late Monday, the US Army Corps of Engineers blasted a two-mile hole in a Mississippi River levee to relieve water pressure that, at its height Monday night, stood at a record-breaking 61.72 feet in Cairo, Ill. The historic river town is located at the bottommost tip of Illinois, where the Ohio and Mississippi Rivers meet.

But that’s only part of it. Originally, before it was straightened at any many points and levees built to protect settlements, town and cities the alluvial plain of the Mississippi Delta was about 300 miles wide. As much as it was a pain and a danger, its regular flooding by the sediment-rich river produced extraordinarily fertile croplands throughout the Delta region – not to be confused with the Mississippi River Delta at the mouth of the river, which is different.

The delta regularly flooded, so we set about changing its course and building levees to protect people and property from the flooding. In an alluvial plain. I certainly do not wish any of these residents any harm or ill-will at this time of hardship. These are the ramifications of our own attempts to master the largest river system in North America. When we made it impossible for the river to periodically dump sediments onto the land through flooding, we made it possible for the river to carry the same same sediment out into the river delta, where it creates massive biological dead zones, aka hypoxia zones in the Gulf of Mexico.

It’s weird and not much salve to see try to this in context of a longer time continuum. But as Fred said, we need more weird.

Woodshed

If you missed Krugman today… well, you shouldn’t miss Krugman today:

These days Americans get constant lectures about the need to reduce the budget deficit. That focus in itself represents distorted priorities, since our immediate concern should be job creation. But suppose we restrict ourselves to talking about the deficit, and ask: What happened to the budget surplus the federal government had in 2000?

The answer is, three main things. First, there were the Bush tax cuts, which added roughly $2 trillion to the national debt over the last decade. Second, there were the wars in Iraq and Afghanistan, which added an additional $1.1 trillion or so. And third was the Great Recession, which led both to a collapse in revenue and to a sharp rise in spending on unemployment insurance and other safety-net programs.

Sure we can talk about and quote long passages from books about the French Revolution, as I’m so fond of doing about any kinds of books, and draw comparisons between now and the run-up to that ghastly epoch. But I’m not sure how much good it will do (though I think a film about Saint Just would be great right about now).

But the more people with megaphones like Krugman take-on and takedown nonsense like the gospel of Greenspan and all of the other Randian balderdash that has so permeated the air waves, sunk most of the newspapers and razed the public squares, replacing them with parking lots for multi-aisle wish fulfillment, the harder the Greenspans et al will have to fight to maintain the BS level that now floats so effortlessly over us all.

Though there is no one like Krugman, there are plenty of others. I heard Stiglitz on NPR this morning and when Steve Inskeep (?) tried to question him about weren’t the stimulus and tax cuts strategies all just the same anyway and the debt was the most important blah blah blah, Joe was having none of it. And called him on the nonsense right away. Can’t believe they had him on. Listen here.

Anyway, these are important steps out of the cow field and here’s to sustaining them. But… no way around the woodshed.

Heeding The Ruins

From Pulitzer-Prize winning author Junot Diaz, who was just in town last month, a meditation on catastrophe.

Hunger, overpopulation, over-cultivation, and dependence on wood for fuel have strained Haiti’s natural resources to the breaking point. Deforestation has rendered vast stretches of the Haitian landscape almost lunar in their desolation. Haiti is eating itself. Fly over my island—Hispaniola, home to Haiti and my native Dominican Republic—as I do two or three times a year, and what you will see will leave you speechless. Where forests covered 60 percent of Haiti in 1923, only two percent is now covered. This relentless deforestation has led to tremendous hardships; it is both caused by and causes poverty. Without forests, 6,000 hectares of arable land erode every year, and Haiti has grown more vulnerable to hurricane-induced mudslides that wipe out farms, roads, bridges, even entire communities. In 2008 four storms caused nearly a billion dollars in damage—15 percent of the gross domestic product—and killed close to a thousand people. The mudslides were so extensive and the cleanup so underfunded that much of that damage is still visible today.

In addition to resource pressures, Haiti struggles with poor infrastructure. Political and social institutions are almost nonexistent, and a deadly confluence of political instability, pervasive corruption, massive poverty, and predation from elites on down to armed drug gangs has unraveled civic society, leaving the majority of Haitians isolated and at risk. Even before the earthquake, Haiti was reeling—it would not have taken the slightest shove to send it into catastrophe.

All this the earthquake revealed.

When confronted with a calamity of the magnitude of the Haitian earthquake, most of us resort to all manners of evasion—averting our eyes, blaming the victim, claiming the whole thing was an act of god—in order to avoid confronting what geographer Neil Smith calls the axiomatic truth of these events: “There’s no such thing as a natural disaster.” In every phase and aspect of a disaster, Smith reminds us, the difference between who lives and who dies is to a greater or lesser extent a social calculus.

In other words disasters don’t just happen. They are always made possible by a series of often-invisible societal choices that implicate more than just those being drowned or buried in rubble.

This is why we call them social disasters.
