Solar Sinter  - Markus Kayser

In August 2010 I took my first solar machine - the Sun-Cutter - to the Egyptian desert in a suitcase. This was a solar-powered, semi-automated low-tech laser cutter, that used the power of the sun to drive it and directly harnessed its rays through a glass ball lens to ‘laser’ cut 2D components using a cam-guided system. The Sun-Cutter produced components in thin plywood with an aesthetic quality that was a curious hybrid of machine-made and “nature craft” due to the crudeness of its mechanism and cutting beam optics, alongside variations in solar intensity due to weather fluctuations.

In the deserts of the world two elements dominate - sun and sand. The former offers a vast energy source of huge potential, the latter an almost unlimited supply of silica in the form of quartz. The experience of working in the desert with the Sun-Cutter led me directly to the idea of a new machine that could bring together these two elements. Silicia sand when heated to melting point and allowed to cool solidifies as glass. This process of converting a powdery substance via a heating process into a solid form is known as sintering and has in recent years become a central process in design prototyping known as 3D printing or SLS (selective laser sintering). These 3D printers use laser technology to create very precise 3D objects from a variety of powdered plastics, resins and metals - the objects being the exact physical counterparts of the computer-drawn 3D designs inputted by the designer. By using the sun’s rays instead of a laser and sand instead of resins, I had the basis of an entirely new solar-powered machine and production process for making glass objects that taps into the abundant supplies of sun and sand to be found in the deserts of the world.

My first manually-operated solar-sintering machine was tested in February 2011 in the Moroccan desert with encouraging results that led to the development of the current larger and fully-automated computer driven version - the Solar-Sinter. The Solar-Sinter was completed in mid-May and later that month I took this experimental machine to the Sahara desert near Siwa, Egypt, for a two week testing period. The machine and the results of these first experiments presented here represent the initial significant steps towards what I envisage as a new solar-powered production tool of great potential.

Japanischer Tango



Drüben bei un loco (”Tangomagazin eines Verrückten”) heißt es zu der japanische Sängerin Ranko Fujisawa:

“Bereits Anfang der vierziger Jahre des letzten Jahrhunderts zog der Tango sie in seinen Bann. Sie lernte Tango auf Spanisch zu singen und ließ sich von Azucena Maizani, Mercedes Simone, Ada Falcón, Libertad Lamarque, Hugo del Carril und Carlos Gardel inspirieren. Sie änderte, sehr zum Leidwesen ihrer Eltern, Ihren Berufswunsch von Opernsängerin auf Tangosängerin. Später heiratete sie Shimpei Hayakawa, Chef des Orquesta Típica Tokyo, in dem sie fortan mitsang.”


Ranko Fujisawa, “Milonga Triste - Yira Yire”:

This alliance doesn’t want that. It wants a selection, not an election, and to rob the people from having a clear choice between parties, which is the exact opposite of what this revolution aimed to achieve. They can call it a National Unity government, a United electoral list, whatever, it’s still designed to rob the people from having any real say on who in the parties gets to represent them locally, unless it’s an independent candidate, and very few of those who aren’t NDP actually have a prayer in hell ‘s chance for winning such an election.

Kein Wort davon, dass keine westliche Demokratie seit dem Ende des Zweiten Weltkriegs binnen eines Jahres härter gespart hat als die Griechen. Kein Wort davon, dass die Troika (EU, EZB und IWF) festgestellt hat, dass die Griechen die “quantitativen Haushaltsziele für das erste Quartal erreicht” haben. Kein Wort auch davon, dass sich die Wettbewerbsfähigkeit Griechenlands verbessert hat wie die Troika feststellt: “Der Außenhandelssektor war dynamisch und trug so zur Reduzierung der Leistungsbilanzungleichgewichte bei.” Das große Problem der griechischen Wirtschaft sind nicht die 4500 Rentenbescheide. Es ist die Binnennachfrage, die unter den Sparauflagen leidet und die Wirtschaftsleistung stärker drückt als von der Troika angenommen – und damit die Neuverschuldung stärker erhöht, den Schuldenstand immer gruseliger werden lässt.
Doch wozu Wahrheit, wenn es so viel Spaß macht, Ressentiments zu schüren. Das ist das zentrale Problem der Euro-Rettung. Sie muss den nationalen Parlamenten entrissen werden. Ansonsten schaukeln sich das Unverständnis und der Nationalismus in Europa gegenseitig auf.

Ich habe in der vergangenen Woche das kleine Büchlein Krieg und Frieden. Die ökonomischen Konsequenzen des Versailler Vertrages des Meisters John Maynard Keynes gelesen und war schockiert ob seiner Aktualität. Man ersetze “Reparationszahlungen/Kriegsentschädigung” durch “Sparanstrengung zur Rückzahlung der Hilfskredite” und man schaudert.

In den Wochenendausgaben von Berliner Zeitung und Frankfurter Rundschau schreibe ich:

“Faszinierend ist das Buch, weil es die politischen Prozesse trefflich antizipiert. Erst führt populistischer Wahlkampf in den Demokratien der Siegermächten (ersetze: Geberländer) dazu, dass den Besiegten (ersetze: Schuldnerländer) immer unsinnigere und nicht erfüllbare Forderungen auferlegt werden.

Damit die ‘Hunnen nicht mit einem blauen Auge davonkommen’, wie seinerzeit im englischen Wahlkampf gefordert. Ein paar Jahre später würden sich die derart unter Druck gesetzten Demokratien wehren, so prophezeit Keynes, indem sie ihre Tributzahlungen einstellen, den ihnen auferlegten Verpflichtungen nicht mehr nachkommen.

Deshalb sei es nicht Edelmut, sondern Zweckmäßigkeit, wenn die Siegermächte dafür sorgten, dass auch bei den Besiegten Bedingungen für Wohlstand und Wachstum herrschten. Eine solche Politik fördere am schnellsten und besten die Freundschaft zwischen den Völkern.

Europa in den Jahren 2010 und 2011 setzt diese Freundschaft, die nach 1945 so selbstverständlich geworden ist, aufs Spiel. Die Art und Weise, wie die Staatsschuldenkrise gelöst werden soll, ist gescheitert. Nationale Demokratien halten den eingeschlagenen Weg nicht aus. Während im Norden die Bereitschaft schwindet, mittels neuer Kredite zu helfen, nationalistische Parteien triumphale Wahlerfolge erzielen, stürzen in den Schuldnerländern die Regierungen über die Sparpakete. Erst in Irland, nun in Portugal.”

The Swamp of Washington and the Morass of the Economy

Washington was built on a swamp. In the summer, temperatures can reach over 100 degrees — as they did over the last few days when I made the rounds of Washington Democrats, repeatedly asking why no bold jobs plan is emerging. 

Here’s a sample of their responses:

“Dead in the water. We’ll be lucky if we get votes to raise the debt ceiling without major spending cuts this year and next.”

“Are you kidding? It’s all budget deficit, budget deficit, budget deficit. Nobody’s thinking about anything else.”

“Republicans beat us up so bad over the first stimulus there’s no way we’re gonna try for a second.”

“We got them [Republicans] cornered on Medicare. Now they want to change the subject to jobs. Forget it.”

“No need. We’ll see job growth in the second half of the year.”

“The President doesn’t want to put anything on the table he can’t get through Congress.”

And so it went. Not a shred of urgency.

This morning I was on ABC’s “This Week,” debating jobs and the economy with Republican Senator Richard Shelby of Alabama. Shelby restated the standard Republican playbook of spending cuts and tax cuts (except for one instant when he inadvertently conceded America emerged from the Great Depression only when government spent big time mobilizing the nation for World War II).

But what struck me most was the similarity between Shelby’s overall attitude and that of the Democrats I talked with — a kind of shrug of the shoulders, a sense that it’s really not all that bad out there, and that nothing can be done anyway. (In the green room, before going on, Shelby told me employment in northern Alabama was actually fairly good and the problem was near the coast.)

The recovery is stalling across the nation yet in the Washington swamp it’s business as usual. 

Americans are scared, with reason. We’re in a vicious cycle in which lower wages and net job losses and high debt are causing consumers to cut their spending — which is causing businesses to cut back on hiring and reduce pay. There’s no way out of this morass without bold leadership from Washington to rekindle consumer demand. 

If the Democrats remain silent, the vacuum will be filled by the Republican snake oil of federal spending cuts and cut taxes on big corporations and the wealthy. Democrats — starting with the President — must have the courage and conviction to tell the nation the recovery is stalling, and what must be done.

Chris Dillow: The Importance of Class

What do you think of Chris Dillow's ideas on class, power, and ideology?

Class, power & ideology, Stumbling and Mumbling: “Nothing makes sense without class” says Owen Jones. He’s right, if we understand “class“ in its Marxist sense.

To Marx - though the idea was implicit in other classical economists such as Ricardo - class was not about lifestyle, but about one’s relationship to the economy. If your income comes from wages, you’re working class. If it comes from capital, you’re a capitalist.

You might reply that, by this criterion, we are almost all working class now. True. Even people who think of themselves as “middle class” are in many cases only a P45 away from poverty. They are objectively working class even if they are not subjectively so.

In this sense, Marx was right to predict that capitalism would produce an increase in the numbers of the working class. Remember, 200 years ago the yeoman farmer, the master craftsman, or the comfortably off idle wife were all significant social roles. They are, I suspect, less significant now.

What’s more, class in this sense is correlated with power: capitalists have it, workers don‘t*. This is because economic power flows to scarce resources and capital is scarcer than labor.

This perspective yields answers to three key questions which cannot be answered without the concepts of class and power:

  • why has inequality increased since the 1980s? It’s because a mix of technical change and the emergence of a mass supply of cheap labor from China and India have increased the power of capital relative to labor.
  • why is the pain of deficit reduction falling upon public sector workers and benefit claimants rather than the “rich”? It’s because the “rich” have power and workers and benefit claimants don’t.
  • why did the state bail out bankers but not ordinary workers who lost their jobs? It’s because bankers have power - though the precise source of this is another question.

This raises the question. If class is so central to an understanding of the economy, why is it so little discussed?

The answer lies in another of Marx’s insights - that false consciousness prevents people from seeing how capitalist power operates. In this sense, the cognitive biases research program throws up some new theories that vindicate Marx. For example:

  • the illusion of control causes people to over-estimate the chances of them escaping the working class through their own efforts, and so under-estimate the importance of collective class action .
  • the in-group heterogeneity bias (which is the flipside of the out-group homogeneity bias) causes people in similar economic positions to exaggerate the differences between themselves and so fail to see their common class position.
  • the just world effect causes people to think that victims are to blame for their fate - so, for example, the poor are thought to be stupid and feckless even if the cause of their poverty lies elsewhere.
  • the optimism bias leads people to think they will succeed if only they work hard enough, and so blinds them to the possibility that their class position will prevent them getting the full fruits of their labour.

And here, I part company with Owen. We cannot have a reasonable debate about class, because cognitive biases such as these are ubiquitous. Successful power structures persist in large part because the way in which power is exercised is hidden from us. The importance of class and the lack of discussion of it are two sides of the same fact.

* I’m simplifying horribly here. Many workers - most obviously the bosses who control firms owned by external shareholders - do have power. I’ll leave this for another time, as I don‘t think it much affects the main thrust of my point.

[....]

After a multi-day traffic jam in Hetaocun, China, Andrew Jacobs of the New York Times wrote: Stranded drivers chain-smoked, stomped their feet against the chill and cursed the government for failing to come to their rescue. As the night wore on, fuel lines froze and cellphone batteries died. The residents of Hetaocun, however, saw the unmoving necklace of taillights from their mountain village and got entrepreneurial. They roused children from their beds, loaded boxes of instant noodles into baskets and began hawking their staples to a captive clientele. The 500 percent markup did not appear to dent sales.
