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.
I’ve sporadically followed Paul Salopek’s six-year walk across the world in National Geographic. As someone who loves to walk in all kinds of terrain myself, I find his a fascinating journey, a wonderful way to see the world up close in all its varied colors, moods and seasons. This to me is real travel; travel measured in footsteps rather than miles in a car or hours of flight. The very word flight conjures images of an attempt to escape rather than a journey to explore and expand one’s horizons. For much of the journey, Paul’s companions have been pack animals and his long treks have brought him to a real and humble understanding of the rich variety of sentient life. For this reason, he speaks with simple sadness of the death of Raju, the donkey who accompanied him on his walk across much of northern India. See the National Geo article here.
I’ve aimed to walk 10,000 steps a day (around 5 miles/8 km) for the past few years and more or less achieved it, except when the weather’s been impossible. I was also surprisingly moved by the death of a feline friend last year. Maybe that’s why the article resonated with me. Maybe that’s why the following passage he quotes from Matthew Scully’s book Dominion lingers in the mind long after reading.
“How we treat our fellow creatures is only one more way in which each one of us, every day, writes our own epitaph—bearing into the world a message of light and life or just more darkness and death, adding to the world’s joy or to its despair… Perhaps that is part of the animals’ role among us, to awaken humility, to turn our minds back to the mystery of things, and open our hearts to that most impractical of hopes in which all creation speaks as one.” From Dominion: The Power of Man, the Suffering of Animals, and the Call to Mercy by Matthew Scully.
“…to awaken humility…” and to perhaps remind ourselves that a warming planet requires us to do this for our own salvation.
There’s a new car sharing company in town called Caroo mobility (caroo.at). Their selling point: e-cars only, offering a choice of makes and models that are fun to drive and easy to manoeuvre in town. They offered initial longer term rentals to volunteer alpha testers, so I took a BMW i3 for 2 days. The test package included 200 free kilometers per day, so I was looking forward to several test drives around the city and surrounding countryside. Recharging at the local energy utility’s (Wien Energie) 22kW installations was a breeze and took around two hours for a full charge (180 km in winter). The company supplied two different charging cards for the car. A smart phone app, quickly downloaded from a wide range of choices on the app store, showed several hundred charging points in and around the city. I should have remembered Murphy’s Law at this point!
We travelled outside the city on the second day, planning to visit two different towns south and east of Vienna, travelling around 220 km in all. Fully charged, the dashboard showed 180 km range left so we thought, armed with two charging cards, no problem. We’ll charge somewhere along the way. The two phone apps of charging stations, hastily downloaded in the morning, chosen at random from more than a dozen, showed scores of charging stations around the two towns and along the highway. We set off, the car fully charged and showing 180 km of range left on a cold, clear winter morning. By the time we reached the first town, 50 km distant, the screen showed we had 115 km of range left, not bad at all, considering the heating was set to 20C and we drove at modest highway speeds. After our visit in the first town, we had plenty of juice left for the next town, 70 km away. Our apps showed several charging stations at the next town, but we decided to play it safe and top up the charge before heading off. Our real EV learning experience began here.
At the first charging station, run by a different utility, our cards were compatible, but the car did not charge. I called the hot line of the utility and was assured, if the pillar light was green, the charge should work. Green lights all around, no charge! The helpful hotline lady said, sometimes these things are finicky. Try disconnecting and reconnect again. Tried this several times, no luck. So we drove around the outskirts of the first town for an hour, looking for other charging stations. Found another one. The chargers were not Type 2, the ones we needed. By this time our range had come down to 90 km, still enough to make it to the next town. Unsure of what would happen there, we decided to head back to Vienna on the highway, where there are a few charging stations. All of the charge stations were badly marked, so we missed the exits to two. Finally pulled into a giant service station where we found a bank of 6 high speed chargers, labelled 150 kW, 175 kW. The plugs were incompatible with our car. I assumed they were CCS, to allow high power DC fast charging, and was afraid they would fry our batteries even if I could connect. There was one 44kW pillar, where the BMW’s plugs were compatible, but our two charging cards were not valid here. So we ended up driving an extra hour back to Vienna to fully charge the car at one of the city’s charging stations.
So my short summary here. The BMW i3 is beautiful to drive with many well thought out details, some design quirks that don’t really work for me on first use (like the back doors opening backwards), beyond my budget, with the bare bones version starting at around €40,000. So when I buy an electric car later this year, it’s going to be a used Renault Zoe at 25% of the price of an i3, with a monthly rental fee for the battery. A word about the rental fee that begins at around €60 per month; it might sound like an additional financial burden, but remember that battery rental will keep your insurance costs low, since the most expensive component of the car does not have to be insured. Worth keeping in mind when you decide on a purchase plan. And the last word. Before I (or you) buy an EV, download a good app of local charge points and make sure you study the specs, not only of the car, but of charging port requirements with their corresponding charge cards or apps.
A quotation from the Psalms recently came to mind. The days of our years are threescore years and ten; and if by reason of strength they be fourscore years, yet is their strength labour and sorrow; for it is soon cut off and we fly away. (Psalm 90, v. 10).
Having reached that Biblical milestone earlier this year, I recall a favourite uncle of mine quoting the above lines at me some decades ago when he reached the age of 70. At that time, his attitude was: I’ve done my bit for the world, and given you a good start. Now it’s up to your generation to carry on the good work. Study hard, find jobs, work hard, and you’ll end up like me, looking back on a life well-lived and enjoying the fruits of prosperity.
Based on the foundations laid by an earlier generation, many in this generation (myself included) worked hard and enjoyed a prosperous life, largely managing to evade the conflicts and other terrible things that happened around the world at different places and different times. We lived in a time of a rising tide lifts all boats otherwise known as trickle-down economics, but somehow gravity didn’t do what it was supposed to do, for the simple reason that human greed defies gravity. So instead of trickling down, money trickled up, slowly at first, until the present day when it’s become a roaring flood. Economic pundits (and most famously the pop group Abba) call it “The Winner Takes it All” syndrome. Economist Brian Arthur who has published a body of work on technology and society calls it “the network effect locking markets in to the domination of a single player.”
So here I am, at three score years and ten years thinking, the work’s not done yet; we’ve not laid the foundations of prosperity for coming generations, we’re not leaving behind a healthy planet for them. There’s still time, but there’s a lot of work to do, easily doable despite the shortening window of opportunity remaining, if enough people join in. Here are some links to steps for a healthier planet.
These are only small actions, but following the suggested prescriptions on only one of these links can greatly improve your own health as well as that of the planet. As a side benefit you might find, like Moses, that your eyes are not dimmed, nor your natural force abated. So here’s wishing you all the best for the future of the planet.
Remember the children’s tale of how the Grinch stole Christmas? Well, here’s a true life tale that tells a similar story. See the following link for the newspaper article that talks about the banned video.

Today’s post is a travelogue, people. Hard to reconcile love of travel with a low carbon lifestyle, so we assuaged our conscience with a journey by train and a few tons of sequestered carbon bought on the website of Tree-Nation, a platform that promises to plant trees worldwide in an ecologically sustainable manner. I hope the promise of the website is true. Please let me know, anyone, if you know otherwise. The tickets of the Austrian Bundesbahn (Railways) said: 83 kilos of CO2 avoided for each of two tickets from Vienna to Ljubljana, the capital of Slovenia. Once there, we rented a small car to travel roughly 1000 km in Slovenia (pop. 2 million, area 20,000 sq. km). We were blessed with sunny skies and post-summer balmy weather, not too hot and not too overrun. Here are a few photos instead of the usual words.
Lubljana is a small, beautiful, walkable city. There is a castle, with dungeons and a respectable dragon, There’s a puppet museum, and a dragon’s egg, at the top of the castle. You can queue for the cable car if you don’t want to climb. Lots of restaurants and cafés in town, along the river, fresh produce galore. Everything reeks of nature here, clean air and lots of people racing through the town on bicycles.
The Postojna caves stretch to 24 km and were carved by the Pivka River over millenia, creating dazzling chambers of stalactites and stalagmites. The Pivka River ultimately flows into the Black Sea. A train takes you 3 km into the interior of the cave and then picks you up again after a guided walking tour of around 2 km on foot. Well worth a visit.
This is a country where most places, especially in the mountains, nights are still dark enough to see the stars. Nature is close to you here. Go there, treat it with as much respect as the local people do. Be prepared to walk a lot if you want to enjoy it. Take your trash with you when you leave, though you might find that the heart lingers, reluctant to leave…
Around 2009 economist Tim Jackson wrote a book called “Prosperity without Growth” that attracted the attention of policy makers worldwide. Maybe the excitement was mainly in the academic community, but I do know that Tim Jackson was sought after by policy makers and politicians for several years after the publication of his work. I assume the latter were looking for advice about ways to institute policies that would ensure deep systemic change. Of course they did not get any useful information. Jackson’s answers only showed what had to be done, not how to do it. That ‘how to’ is the preserve of politicians and, ultimately us, the electorate.
This brings me to the real reason for failures of governance. Us. We. The. People. Many years ago I had a brief interview with the foreign minister of a country and asked him why he did not implement what we both agreed would be a common sense measure to enhance regional food security at practically no cost. The helplessness implicit in his reply was illuminating. One of the ‘aha’ moments of my life. “Bring me a mandate,” the minister said, “and I will gladly take this decision.” In that moment, like cascading coins from a slot machine, the realization dawned. In democracies, it is us. We have to use our starling intelligence, as members of the swarm to mould societies as we wish. In travels through many countries I’ve noticed that where people sit back and complain about the government, the corruption, the lousy politicians; they are not doing anything much to change the status quo.
In the words of George Monbiot, writing in the Guardian, we have only the one planet, but we’re living a four-planet lifestyle. In 2018 Earth Overshoot Day fell already on the 1st of August. This is the earliest date since the practice began in the 1970s, calculated by the WWF and the Global Footprint Network. This is the date when humanity’s annual demand on Nature exceeds what the Earth can regenerate over the entire year. In other words, this is the date when we begin to rob the bank. And most of us, good people, in our struggle to provide a comfortable life for our families, in ensuring livelihoods for our children, are totally oblivious to this. So before the politicians act, we have to change ourselves, reduce our demands on the planet. Sometimes this can mean enriching our lives by doing more with less. And very often this change begins with an inward journey that only we can make. No politician can ever do this for us. The transformation that the world needs is inside of us. All of us.
