Thermoacoustic Cooling

Although this blog was begun to publicise my own fiction, there are so many interesting things to write about that the fiction element has been displaced by other kinds of stories; stories about geopolitics, concerns about global change (of which not least, climate change), and new developments in science and technology.

It currently seems to me, as an informed layperson, that the answer to the planet’s global warming crisis lies primarily not so much in technological advances as in social engineering for change. For example, livestock farming produces 18% of global greenhouse gas emissions. Halving the consumption of meat, to take only one measure, would have enormous health benefits for individuals and at a stroke, reduce greenhouse gas emissions. That’s the equivalent of removing the 2015 contributions of the two most populous countries, India and China!  According to a 2006 FAO report, Livestock’s Long Shadow (416 pp.), cattle alone are responsible for more global warming than all forms of transportation put together.

Another quick fix would be to reduce national defence budgets and invest the money in women’s health and education, easier said than done, considering the political madness that one sees in countries around the world. This too can be changed if enough people around the world set their minds to it and realise that we, the people, are the drivers of political change. Politicians are servants. They are merely people responding to our collective angsts and biases.

As global temperatures rise, people try to cope by installing air-conditioning units. This compounds the problem, since electricity consumption multiplies and heat dissipates to the outside world, creating urban heat islands and causing yet more global warming. It’s like polluting an ocean. Imperceptible when only one person does it, but massive when done by millions. Here’s an exciting technological fix in the works that might help to solve the air-conditioning problem: thermoacoustic cooling.

The principle was apparently observed by glassblowers more than two centuries ago. They noticed a sound was created when blowing a hot glass bubble at the end of a cold, long tube. 19th century scientists figured the sound was produced by the thermal gradient, and resonance was giving extra energy to the air in the tube. Apparently the first modern application to capture this energy for cooling was used in NASA’s Space Shuttle Discovery in 1992. Today, there seem to be two companies, in the Netherlands and in France, who offer solutions based on this principle for pollution free cooling. Here’s a link to the websites of Dutch company, SoundEnergy and France-based Equium. The sooner such companies are commercially  successful, the better for the planet. Here’s a simple demonstration of the principle showing the working of a thermoacoustic engine.

Three Days that Flu by

I had the flu last week. It probably wasn’t a flu, actually. Just a cold and a fever that kept me in bed for three days. What a bore, you say. No. It wasn’t at all. Because the illness opened up a window of time where I could indulge myself and read what I wanted to. I was on a train journey when the fever and chills began, so I wrapped myself up in my warmest clothes and began to read Madeline Miller’s wonderful book.

Circe, by Madeline Miller. When I started the book, I knew of Circe only as an appendage to Odysseus in Homer’s Odyssey, an also-ran who played a small supporting role in the life of a classic hero. She was the one who bewitched his men and turned them into swine. In passing, Circe is spoken of as a daughter of Helios the sun god and an ocean nymph. In this book, the heroes (Jason and Odysseus among them) are shown to be flawed human beings with all too human frailties that undermine the lives of those closest to them. The parallels to the 21st century fall of several iconic heroic figures are very close and inescapable. The author brings Circe to magnificent life; a courageous woman who battles her fate and in the end, defies her father to escape the eternity of exile on the island of Aiaia to which Helios has condemned her. Rather than simple mythology, this is a beautiful coming-of-age story (over a period of several centuries, admittedly); a story for our time about a long suppressed and battered woman who finds her voice. The miles flew by and the train journey soon ended. By the time I finished the book I was home, the discomfort of the train journey behind me, and crawled tiredly into bed. After several cups of tea I fell asleep, and when I awoke it was bedtime. I was wide awake, with a runny nose, a bit of a cough, and no chance of going back to sleep. So I started another book.

Die Trapp Familie: die wahre Geschichte hinter dem Welterfolg by Gerhard Jelinek, Birgit Mosser. Many Austrians find it annoying when tourists gush about The Sound of Music and think that it represents a true picture of the country. They see the movie and the musical as a candy floss image of the truth. So this painstakingly researched history by two reporters sets the record straight. For me the real hero in the story is Captain von Trapp, a highly decorated U boat captain. More impressive than his wartime exploits are his apparent human qualities. According to his own writings, he genuinely agonized about enemy loss of life when attacking enemy shipping (but followed duty and did it anyway). He was a devoted father, had a harmonious marriage to his first wife, the mother of his first five children. It didn’t hurt that she was a wealthy English heiress who came from a prominent industrial family based in Trieste. An Irish cousin of his first wife who spoke no German lived in their household for several years. So his children grew up speaking English as well as German. This stood them in good stead in their burgeoning international career. Apparently it is true that the good captain used a ship’s bosun pipe with individual calls to summon his children, but only because they lived in a rambling house with extensive grounds. He was by no means a martinet and when Julie Andrews, pardon, Maria Kutschera, arrives as a childrens’ governess, the family was already very musically capable. They sang in a choir with Captain von Trapp playing first violin and two of the older children on instruments. Anyway, just as in the movie he does really marry the governess, and it is her driving ambition that makes them internationally famous. From this point on, the Julie Andrews myth seems to be closer to the truth. Good reading for the first night and second day of the fever.

Becoming by Michelle Obama. I was feeling much better as I started reading, but soon realized I wasn’t going to get completely well until I’d finished this book uninterrupted. It was a long and easy read. The narrative flowed unpretentious, self-aware and honest. After finishing the book, two impressions were very clear. This woman would be a great politician if she wanted to be one. Second was the certainty that she would never, ever go into politics. And so I delved into the life and times of this fascinating couple. Interestingly, only the last 30% of the book is dedicated to the White House years, presumably because so much of it is in the public record.  It is very clear that the focus of her life, apart from the causes she has been associated with, is her family. The immediate family and the extended family. In any case, it was a refreshing and compelling read and I emerged from the book completely well enough to go back to the normal routine of time spent outdoors and other work.

Never Say No to a Witch: Mai dire no ad una Strega

This is a short story with a punch line in Italian that goes to show that some jokes or puns are untranslatable. But I’m going to try anyway, in an attempt to cross cultural barriers, as we all urgently need to do these days.  So here goes!

Never Say No to a Witch (a short short story)

Two failed crooks decide to rob a bank. They’ve both attempted bank robberies alone in the past, but their efforts have failed. Miserably. One has tried legal and accounting methods to embezzle money, and was forced into hiding when the embezzlement was discovered. The other attempted armed robbery and was forced to flee when the carabinieri turned up within seconds. The police car happened to have been stopped right outside the bank in a traffic jam when the emergency call came through. So these two hapless wannabes decide to join forces and pull off a major bank robbery using brain as well as brawn.

The smart(er) crook uses deceit and inside knowledge to determine the precise hour and date for the robbery. The second one gathers untraceable weapons from the black market to use in case force is needed. They slip into the bank just before closing hours on the appointed date. They force the terrorised customers and bank staff to the floor and storm the vault. At the open door to the vault sits an elegant black-clad lady behind a desk with a bottle of yellow liquor and two empty glasses on it.

“Move over,” snarls one, brandishing his weapon.
The woman calmly fills two glasses with the yellow liquid and proffers them.
“Have a glass of Strega,” she smiles.
“I said move over,” he snarls again. His finger tightens on the trigger.
In the split second before he fires, she flings the liquor in their faces and Poof! There is a blinding flash of light and the two men disappear! The elegant lady smiles and refills a glass.
“Mai dire no ad una Strega,” she whispers as she takes a sip. Never say not to a witch. (Translator’s note: Strega is an Italian liqueur. The word also means witch in Italian).

I dreamt up this story some time ago and the makers of Strega are quite welcome to use it in one of their ads if they wish. But the story is also meant as a parable and a warning to the European Union. If the bank in the above story represents the citizens of the united nations of Europe, one of the two robbers stands for the nationalist factions in the various countries that led to Brexit, the Italian rebellion, the rise of the AfD, and the move away from democratic norms. The second crook, the one who uses his legal background to determine the best time and method of entry represents the bureaucracy of Brussels and of the European parliament. Everyone is entitled to an honest wage, but there are too many EU bureaucrats with tax-free salaries who are completely out of touch with the citizens they represent. When they prescribe austerity measures for countries that fail to meet certain economic criteria, they should practice austerity on themselves as well, so that they share in the pain they inflict on the collective. This principle is just as true within individual countries of course.

Politicians seem to have forgotten that the word “minister” implies that one is a servant whose duty is to minister to the well-being of the public.It is reasonable for ministers and prime ministers to enjoy rank and honor as a reward for self-sacrifice and public service. But they are not royalty. They are not infallible. They are not entitled to rob the bank. As someone who is ardently pro-EU, I see there is great need for democratic reform within the EU. I also see the Brexiteers, the AfD, the xenophobes, and the far-right of every country are like the second robber, the unintelligent one, looking to force as a way to getting the reform that they want. But they are using failed methods. Nationalism, xenophobia and fascism have been tried before, and have only led to repeated wars and mass destruction on the continent. Europe needs the EU more than ever. The world needs the EU more than ever.

Leadership Hope for a Warming World

Several years ago, an Italian acquaintance said to me, “The growth of the Roman Empire was driven by testosterone, you know.” He was a polyglot polymath; a materials scientist by profession, and a keen historian who sometimes spouted Greek and Latin quotations to illustrate the points he made. Julius Caesar, as a promising young general in his thirties, felt like an under-achiever and a failure. He is known to have lamented that Alexander had conquered most of the known world by the age of thirty, while he himself was only a Quaestor (a local magistrate) in Rome. Caesar was forty years old when he formed the first Triumvirate with Crassus and Pompey. He then went on to defeat the Gallic tribes of modern day France over the next eight years, killing more than a million Gauls and Germans in the process (according to Plutarch) and enslaving a million more. Presumably, by the mores of his time, these deaths were considered necessary to establish rule of law, discipline unruly Roman citizens with firm leadership and ensure stable government.

After the Second World War, with American leadership and the newly instituted United Nations organizations in 1945, it was widely believed that conquest and rule by force of arms was a thing of the past. Post-1945 the world entered an era of global peace and the longest absence of major wars mankind has ever known. If today’s world outlook seems bleak, blame it on the internet and social media, which are able to convey local impacts of minor skirmishes into our homes with larger-than-life images. Brutal killings appear immediately on the screens we carry in our pockets, or on laptops and smart tablets in homes and offices. When the Cold War ended, American philosopher Francis Fukuyama famously declared the end of history. In a nutshell his thesis was: with the spread of globalization and its accompanying prosperity, liberalism would spread around the world. Fukuyama’s book “The End of History and the Last Man” was published in the heady post-Cold War days of 1992. Today Fukuyama confesses: Twenty five years ago I didn’t have a sense or a theory about how democracies can go backward. And I think they clearly can.” (Washington Post article here)

On the other hand, Harvard psychologist and popular science author Steven Pinker argues that humanity is currently experiencing decreasing levels of violence (TED talk, 20 minutes) However he argues that liberal values are under threat from authoritarian populism, religious fundamentalism and radicalism of the left and right. There is no doubt in my mind that liberal democracies will do better than dictatorships and autocracies in tackling the gravest problem facing humanity today, global climate change. And it is mainly in democracies that the #MeToo movement is taking shape. People involved in the movement are asking questions and demanding action from their governments. Have we reached a tipping point? Can this watershed moment go beyond words to drive meaningful action? My answer to these questions is an emphatic yes. The fact that the movement has unexpectedly taken root in Asia is an enormous portent of things to come.

African press reports indicate that in many countries on the continent, women are afraid to talk about sexual harassment, especially in many of its conflict zones. According to this Zimbabwe newsletter, four of the five riskiest cities for sexual assault and rape are in Africa. There also appears to be a direct correlation between sexual harassment and  geopolitics. The greater the gender equality that exists in a country, the less likelihood of autocratic leaders. Strongmen (and wannabe strongmen) look on the exercise of power as a kind of pissing contest, with the Trumps and Erdogans of this world trying to outdo the Putins, Kim Jong-Uns and Dutertes. More women leaders coming to power in countries around the world as a result of the #MeToo movement would be the best news for global climate. Women are less likely to indulge in geopolitical pissing contests. On the one hand women are generally more inclined to collaborate and cooperate and and on the other, their plumbing discourages such childish displays, leaving them with more time to get on with the urgent tasks of governing.

Chocolate, Figs and Ham

Coming across some unsweetened chocolate containing dried figs and ham (prsut), the combination seemed so unusual that we picked a packet up to try at home later. This was in a little shop near the open air market of Ljubljana, the eminently walkable capital of Slovenia. The combination, when we tried it, was delicious and to be highly recommended. Tasting this reminded me of a bitterly cold winter evening some years earlier, wandering through a Christmas market in Vienna, when I was stopped by a bearded man who looked like a Peruvian pan flute player.
“You look cold,” he said.
“Yes, I am cold.”
“Try a mug of Aztec chili chocolate with rum,” he said. “It’ll warm you up in no time.”
So we bought two steaming mugs of his brew and soon felt a pleasantly mild fiery glow spread through our innards. It helped us forget frozen hands and the biting cold for a good half hour. Figs originally came from Asia Minor, modern day eastern Turkey, but they spread early all over the Middle East and the Mediterranean. Chocolate probably originated in Olmec lands around 1000 BC where they called it kakawa. The origin of the word chocolate is presumably from an Aztec word ‘xocoatl,’ a bitter drink they brewed from cocoa beans. Here’s a link to a brief history of chocolate.

A gourmet friend told me several years ago about a trip to Sicily where he ate the most delicious lasagna he’d ever tasted, in a nondescript restaurant in a small village. Curious, he asked the owner, who was also the cook, the secret to his lasagna. “Unsweetened chocolate,” the man explained, pointing to a thin brown layer in the middle.

The Olmecs gave us chocolate and avocados. Kiwi fruit were brought out of China and found a new home in New Zealand where its name changed from Chinese gooseberry to kiwi. Okra originated in Ethiopia and now is used by households from India to Florida. Sugarcane spread from India and New Guinea to the rest of the world. Potatoes and tomatoes also originated from South America, while chick peas came from Turkey and the Middle East as long as 8000 years ago. Ethiopia also gave the world coffee, probably via Mocha in modern day Yemen. Tea, as is well known, came from China.

Where is all this leading to? To people, of course. To the people who consume these foods and beverages all over the world. Thank goodness for the free movement of food and food habits. A world without hummus, okra, tomatoes, potatoes or, God forbid, coffee and tea would be a world of culinary despair. So the way the world is going right now, most nations are saying, ok, we’ll take your food but not your people. Imagine the long-term global poverty and despair that then ensues, not only immediately, but in the long run. Imagine a world of monocultures with no biodiversity! So next time you go to vote, remember to vote for culinary diversity, and the people that come with it. This idea is underlined in the following illustration and article from UK think tank Global Future about future diversity in business leadership.

A Gift to Gaia

The world is full of stuff and many parts of the world are drowning in it. Except for those parts of the world where people don’t have any stuff at all. Nothing to speak of.

Within our family, we stopped giving stuff as gifts quite some time ago. Nowadays, we mark occasions such as birthdays, anniversaries and significant celebrations with the gift of time.

The planet has plenty of time to spare, even though humanity does not. In a few hundred years, or a thousand years, even if mankind has pursued its current illusion of prosperity to oblivion, the planet will sedately roll on, and prosper without us. Just as it prospered long after the last dinosaur ceased to exist.

When Isaac Watts wrote his hymn, based on the 90th Psalm, he was not thinking of humanity’s self-induced annihilation as he composed the following lines.

Time like an ever rolling stream, bears all its sons away
They fly forgotten as a dream, dies at the opening day.

For those ‘successful’ busy people who have no time at all to spare, here’s a suggestion for a gift of stuff that’s actually a gift to the planet and buys us time. This gift has the added benefit of helping people who don’t have much stuff at all. Here’s a link to an Impact Calculator from Solar Aid. With enough gifts like these, perhaps one day we can sit down with Gaia and have the last laugh together.

Soccer as Development: Rooting for Senegal

Aristotle famously said, one swallow does not a summer make. In the same vein, one could also say, eleven soccer players do not a nation make. Nevertheless, the collective pride of a nation gathers behind its soccer team once every four years while millions of people take heart or lose hope when their national team scores goals or is defeated. One way of looking at soccer is as a proxy war. Much better to slug it out on the soccer field than on the battlefield. But to my mind there’s a connection between soccer and development as well.

Economic development has a lot to do with collective confidence. Way back in 1990, Cameroon’s Roger Milla became an international star on the World Cup stage in Italy that year. He was one of the oldest players on the field, and his habit of doing a victory dance in corner field after scoring a goal made him a celebrity worldwide, not only among soccer fans. It was during these World Cup weeks that I drove to Schärding, a small town in Upper Austria, close to the German border, to spend a weekend exploring a newly opened bicycle path between Schärding and Passau in Germany. In the evening, after a long ride, when I entered the Gasthaus where I had taken a room for the night, the owner behind the bar did a double take and shouted, “Schau, schau. Der Roger Milla ist da.” Look, look, there’s Roger Milla. Everyone turned around to look, some cheered, and I could think of nothing better to do than imitate Roger Milla’s victory dance. The evening went off very well after that. Some of the regulars in the room seemed to think I really was Roger Milla and asked me how come I spoke such good German. (I was born in India, by the way and none of my friends think I even remotely resemble Roger Milla).

When I describe this incident, people ask me: how did you feel? Wasn’t that terribly racist?
Wait a minute, I tell them. Don’t be so quick with the R word. In a part of the world where there are few visible minorities, most people tend to be ethnically challenged. They see only themselves and other people like them, and everyone else is simply ‘the other.‘ This ethnic ignorance is the source of strength of divisive political leaders; the Orbans, the Kaczynskis, and the Petrys of Central Europe. To give an example of how I see it; I recently went on a field trip with a bunch of bird watchers. Where I only saw sparrows and the occasional bul-bul, they saw flycatchers, minivets, drongos, three kinds of woodpecker, kingfishers and many, many more. So too, with the ethnically challenged. Until they learn to see human life in all its rich variety, they will see only two kinds of people: us and them!

So that’s why I wish the Senegal team does well on the soccer field and even hope they win the World Cup, for maybe then, even the most ethnically (or ornithologically) challenged among us will finally realize: there are not only sparrows in Senegal, there are crowned eagles too.

Finding the Right Words

I read a review of a new book called “Translating Happiness” that describes the emotional privileges enjoyed by people who speak more than one language. The idea of multi-lingual people leading richer lives has been expressed in many different ways by thinkers through the ages. A Chinese proverb (there’s a good Chinese proverb for every occasion!) says that Learning is a treasure that will follow its owner everywhere. A Spanish proverb puts it more strongly and says One who knows two languages is worth two. Roger Bacon calls knowing more than one language the gateway to wisdom.

In Smilla’s Sense of Snow, author Peter Hoeg has the main character explain in the book that the Inuit and most other Greenlanders have a much more nuanced and deeply intuitive feeling for the varied facets of snow and ice than the rest of the world. To prove this, Smilla says there are 28 different words in Greenlandic languages to describe snow in all its moods and varieties. Although the book is a very readable thriller, a scholarly article I found actually lists 128 words for snow in Greenlandic languages. This is surpassed by a BBC news report of a University of Glasgow study that claims the Scots have 421 different words for snow. Picturesque examples include feefle, “to swirl” and snaw-pouther, “fine, driving snow.” Here I see rich pickings for an academic study of differences between Greenlandic and Scottish use of wintry language.

People who live in island nations and speak only one language are often the quickest to admit how culturally impoverished they are. By that measure, the United States is a linguistic island, with the vast majority of its populace militantly indignant when they encounter people who don’t speak English. An otherwise intelligent and sensitive American acquaintance of mine who travelled abroad for the first time recently made so many derogatory remarks about European customs she encountered. What made her so indignant was that certain customs were different from what she was used to at home. Such people, however decent and well-meaning, are like snails carrying their houses on their backs. They need to ditch their shells and learn to travel light.

Breaking News – the news is broken

Most media outlets seem to operate under the principle that bad news is good news or alternatively, good news is not news. They may be right, in terms of profitability. But they are definitely wrong, in terms of the collective well-being of humanity. This blog is not dependent on readership or advertising revenues, so it can afford to print good news without fear of losing its readership. So here for a start is good news from the energy front.

All of the electricity used by two of the world’s largest corporations, Apple and Google, were from renewable sources by the end of 2017. This is a remarkable achievement, considering that each of these companies uses more electricity than many small nations, not least to power immense data centers scattered around the world. So now, if you have worries about the amount of personal data Facebook & Co. are collecting about you because of their opaque terms of usage, rest assured that they’re not polluting the planet in the bargain.

But seriously, there’s lots of impressive news in the energy area alone. Here’s a chart, courtesy of National Resources Development Center, showing how prices have come down for major clean energy technologies.

Chart from NRDC: click to enlarge

Since clean energy is one of the basic requirements for human development, there’s not much stopping world-wide implementation, is there? Capital for investment? It’s increasingly concentrated in the hands of a few–rich corporations and rich individuals. So are we ordinary mortals totally helpless? No, not at all. But we have to make smart choices as customers. We can enrich our lives, and the planet in the process, by getting off the mindless consumption lifestyle that the glossies would have us aspire to.

In one hour, the earth receives more solar energy than the world uses in one year. Now that’s good news and worth repeating, even if its not new. So why are companies producing more dirty diesel cars and building more fossil fuel power plants? Because switching technologies means moving out of comfortable niches of expertise that would otherwise become useless; it would mean new investments, experimenting with new technologies, and why should they take all these risks when customers are flocking to buy new models anyway? As engine size and horse power of new automotive offerings increase, so do their profits, and they see even less reason to invest in new technologies. It’s only we, the customers, who can break this vicious cycle.

English speaking news readers tend to digest information from an overwhelmingly anglocentric or eurocentric point of view. Hence I was not surprised recently to hear a friend accuse the Chinese of polluting the planet when actually, despite (or perhaps because of) a totalitarian regime, they are doing more to clean up the earth than any other nation. For example, the southern Chinese city of Shenzen alone runs a fleet of 16,000 (yes, thousand) electric buses; more than the rest of world combined. So while air quality in Beijing might be abysmal, this past winter, particulate pollution was 50% less than in the previous year. This from no less a source than the US Embassy in Beijing! One reason for the lower levels of pollution might be that China installed more than 53 GW of solar power in 2017.

The above facts don’t make me an apologist for an autocratic government where power is increasingly concentrated at the top. This is undoubtedly a very worrying tendency, one that is being seen in several other large countries like India, Russia, Turkey, China and the United States. In the US case, its robustly democratic political system has been hijacked by corporate lobbies. Nevertheless there is good news coming from each of these countries, and I will try to highlight these bright spots in future posts.

A School Playground with no Women

As parents, we all have a duty to find out what happens to our children in school. We have to protect weaker children from school bullies who might otherwise terrorize their juniors.

Imagine the school bully unchecked after a playground fight. “You,” he shakes a menacing fist at a defiant runt. “Don’t dare talk back to me again, or else…” he pulls a knuckle duster from his pocket and shoves it in the little boy’s face. “Or else you’ll have a bloody lip…” The little boy, whose name is Cutter, looks around to the smirking head boy sitting on the playground fence for support, but the head boy says nothing and does not move.

“I’ll see he doesn’t talk back to you.” stammers another little boy, whose name is Kurshid. The bully shrugs, looking out of the corner of his eye at the head boy sitting on the fence. He remembers that some time ago, the head boy came to Kurshid’s aid when another bully smacked him on the head, took away all his marbles, and kicked him out of the playground. On that occasion, to everyone’s surprise, the head boy beat the bully to pulp and had him expelled from the school. Everyone knew the head boy had done this because he liked Kurshid’s marble collection.

“Now be good boys,” says the harried teacher, who knows the boys don’t respect his authority in the least. “Be nice. Don’t all gang up on the smallest because he won’t play with you,” he says, shrugs, and turns away, knowing the fighting will start again as soon as his back is turned. Meanwhile the sadistic head-boy sits on the fence and smirks gleefully. He’s just sold a knuckle duster to the biggest bully on the playground and can’t wait to see it in action.

There are no female teachers present. This scenario is playing on the world stage. Here are the real players in this drama.
Cutter – al-Thani clan, Qatar
Kurshid – Emir of Kuwait, mediator
School bully – Crown Prince Mohammed bin Salman, Saudi Arabia
head boy – Donald Trump, United States
another bully – Saddam Hussain
marbles – oil
harried teacher – UN
knuckledusters – US arms sales to Saudi Arabia
Other key actors offstage:
chief hoarder of marbles – China
school clown – Kim Jong Un
neighborhood dope dealer – Putin
anxious parents -Rest-of-the-world

A few weeks ago, the Guardian newspaper published a list of 13 demands made by Saudi Arabia and friends. Qatar is to comply with all of them within ten days, or else… (see https://goo.gl/KDdkeP)
