Drive Easy


If someone discovered the equivalent of a few more Saudi Arabias tomorrow, except the oil wouldn’t cost us anything, you’d think it would break the Internet. It would make screaming headlines in tomorrow’s paper. The same should be true if someone discovered a free way to cut our oil use, which amounts to the same thing.

It would also be a great way to fight climate chaos. As the pollution from our cars and factories gradually fills up the Earth’s atmosphere and traps heat from the sun, it disrupts the normal weather patterns and causing hotter weather in one place, wetter weather in another, and more powerful storms elsewhere. The less fuel we use, the more we slow down the process of climate change to a point that the Earth’s systems of wind and currents can settle back to something like normal.

Imagine if someone found a way to dramatically reduce accidental deaths, increase the lifespan of our cars, save money, and make our neighbourhoods safer. You might imagine everyone talking about this new approach, and every local community proudly adopting it.

We have found a way to do all those things – save fuel, fight climate change, and make us safer, and save money all at once. It’s called driving slowly.
Strangely, though, this simple method gets very little attention: Most drivers assume they can and should hurtle towards their destination at dangerous speeds that devour fuel and money – not just at the speed limit, but 10 kilometres over it.

But the higher your speed, beyond a certain point, the more fuel you use per distance travelled. As Kris DeDecker described in Low-Tech magazine, “air resistance (drag) increases with the square of speed, and therefore the power needed to push an object through air increases with the cube of the velocity … If a car cruising on the highway at 80 km/h requires 30 kilowatts to overcome air drag, that same car will require 240 kilowatts at a speed of 160 km/h …

Thus, a vehicle needs eight times the engine power to reach twice the speed. In principle, this means that fuel consumption will increase fourfold (not eightfold, because the faster vehicle exerts the power only over half the time).”

In other words, travelling half as fast could save you up to 75 percent in fuel costs. Since 60 percent of the world’s oil is used for transportation, if everyone cut their speed in half tomorrow, this would reduce world oil consumption by almost half. Obviously this is theoretical and the world isn’t going to do that tomorrow, but you don’t have to wait for the world before slowing down yourself.

Such a simple equation inevitably has many complications, but none that are fatal to the basic idea. DeDecker does note that today’s cars are unfortunately designed to be maximally efficient at higher speeds, which reduces the 75-percent figure somewhat unless the engines are adjusted – and, in fact, most automotive sources say the best speed is between 50 and 80 km/hr (35-55 miles/hr). It also doesn’t allow for urban congestion and frequent stops – although slower speeds would discourage the unnecessary trips that cause congestion, and make bicycles and taking public transportation a more cost-effective option.

But maybe 75 percent, or whatever figure you can achieve by driving slowly, is not enough – maybe you demand an additional 500-percent increase in efficiency on top of that. There is a way to do that as well: add four more passengers to your car.

Passengers might be the most under-appreciated factor in how much fuel and money you waste. As I write this, for example, a business headline boasts of Toyota’s multi-million-dollar plan to boost fuel efficiency by 25 per cent, with the usual discussion of what this will mean for the economy and the climate. Any of us, however, can boost the efficiency of our cars by several hundred per cent instantly, with no additional expense or technology, simply by getting more people in the car.

This fact is also forgotten when we judge car owners by the wastefulness of their vehicles. An SUV is a spectacularly inefficient machine compared to a Prius, for example, but pack that Dodge Durango full of people and suddenly it is greener than the electric hybrid driven alone. Your bus could be less efficient than an SUV in kilometres-per-litre, yet all of you bus passengers are making one of the greenest transportation choices around, thanks to the fact that so many seats are filled.

According to the website carfinance.ie, the average car in Ireland, driven 10,000 kilometres a year, will cost 1,750 euros in petrol. Divide that by four people, however, and you each save 1,300 a year.

Of course, you might say, such actions are a drop in an ocean. But change comes from thousands of such small actions. It was generally big-budget extravaganzas that got us into the situation we are in; the modest, the tiny and the slow are more likely to get us out.

Earthships


This article originally appeared in the Kildare Nationalist newspaper. 

All of us live in homes that are dependent on larger systems to operate: electrical grids, heating and plumbing. Most of our homes require large amounts of energy to run, which we burn fossil fuels to acquire. We also have all kinds of waste products – tires, soda cans – that fill up landfills, never to be used again.

A few decades ago, however, one American began to think through, meticulously, how many of these problems could solve each other. Michael Reynolds called his solution the Earthship, a home built to be as efficient and self-sufficient as possible, using mostly free materials that are either natural or recycled. The Earthship is designed to require as little energy as possible to maintain, to recycle its air and water as much as possible, and to provide food for people inside the house.

In order to keep the temperature as constant as possible, Reynolds planned for his Earthship homes to be surrounded by earth on three sides, usually built into hillsides. As the weight of the surrounding hill would make straight cement walls unstable, Reynolds created walls made of earth-filled tires, curved to allow the hill’s pressure to dissipate around the structure.

Tires turned out to be an inspired choice for building material – there are more than two billion old tires in the world, and they do not biodegrade naturally, so they clutter up landfills. They do hold earth well, however, and a wall of connected tires covered with a plaster can be very sturdy, earthquake-resistant and fire-resistant.

Reynolds also designed the top of the structure to catch rainwater to use for the household, and the buried sides to insulate the house. Other spaces around the front can be made with cement – but Reynolds likes to use old soda cans as filler, to make the structures lighter and to save money buying cement. Another popular technique for Earthships is to use old glass bottles as filler, thus saving mass and cement while also creating insulation – from the air inside the bottle – and creating a small coloured window, all at once.

On the south face of the Earthship – or the north face, if it’s being built in the Southern Hemisphere -- Reynolds placed large windows under an overhanging roof, letting the low sun into the house in the winter when it’s most needed, and keeping the high sun out during the summer when it’s needed least. All day, the sun warms the interior walls and floor of the Earthship, which release the heat slowly over the cold night.

Since the front windows act like a greenhouse, most Earthship owners create a garden bed just inside, a mini-greenhouse in which they can plant crops. The plants, in turn, can be supplied with a steady supply of water from the house with wastewater from the shower, bath, or sink. The system acts like a permaculture garden, which I wrote about in this column a few weeks ago – everything is recycled over and over, and nothing is wasted.

The effect of all this is a home that anyone can build themselves, using readily available materials, and that will stand up to time and the elements. Such homes can be fitted for electricity, heat and water pipes, of course, but since they are designed to get maximum light and heat from the sun and typically have rainwater collection, and recycle everything in the house, there is little need for bringing in energy or resources from the outside. If people around the world built using these principles, much of our annual expense on mortgages, heating and food would disappear, as would much of our society’s carbon emissions that are changing the climate.

The Earthship concept grew by word-of-mouth, and now there are Earthships – using very little energy and largely off-the-grid – in almost every state of the U.S. The technique is now expanding into Europe, although might need to be adapted somewhat to a climate like Ireland’s, though would probably need to be built level to the ground rather than under it in this damp country. 

If you are considering building a home yourself, look into the Earthship design – check out Michael Reynolds’ books, Earthship I, II and III, or Google “Earthship,” and consider learning more about this ingenious method.

Father Christmas, homesteader


Hello everyone. As I mentioned, the last couple of years have thrown my life into some chaos, and not just because of the pandemic. Now, however, things have settled down, I’m writing again, and will have original material ready in the new year. In the meantime, have a great Christmas.

 This time of year, my daughter used to have one favourite story: Raymond Briggs’ Father Christmas, the story of Santa’s rounds on Christmas night. It’s one of my favourites as well, if for different reasons.

In this graphic novel, silent but for a few grumbles and greetings, there is no Ms. Claus, elves or secret toy-industrial complex. Father Christmas, here, is an old man living in apparently contented solitude, dutifully venturing out yearly to make his deliveries. He endures storms, fog, sleet and high winds across the world, complaining the entire way and occasionally strengthening his resolve with a drop of liquor.

Such an unsentimental portrait might sound depressing, but it makes Santa more human, and more comprehensible, than the usual laughing caricature. Briggs makes him a hard-working man performing a service we value; Briggs could easily be showing the daily routine of a miner, a fisherman or a farmer. At one point Santa passes a milkman also making deliveries, and they exchange pleasantries without stopping – and even on Christmas morning, the milkman must make his rounds as well.

What I particularly like, though, is that Santa seems to live on a homestead. He starts his morning gathering hay for the animals, is pleased to find two winter eggs from the chickens, and has breakfast with tea. He stokes the small stove, similar to the one we use to burn our bog turf. You wouldn’t be surprised to see a vegetable garden or greenhouses out back.


The book doesn’t say where he lives, although children here say Santa lives in Lapland – northern Finland --- rather than the North Pole. From the tea to the Christmas pudding, though, it looks like working-class Britain in the mid-20th century, the “deeply conservative land” that David Kynaston shows through contemporary diaries in his impressive Austerity Britain. It’s the Britain G.K. Chesterton or C.S. Lewis might have recognised, the life an old man might have lived in Britain when the book was written in 1973.

Father Christmas and Austerity Britain would seem two very different books, but they both focus on the similar cultures, eras and intimate details of living – supper, chores, schedule. Minutiae like this bring earlier eras to life in a way most histories miss, and offer a casual vision of an austere but civilised world that we might be able to revive, as an alternative to worse futures.

In a small room Father Christmas sleeps under quilts, in long johns, with a hot-water bottle, for heat was precious. The bed-stand looks of rough wood, as though he carved it himself, and on it he keeps his teeth and a wind-up alarm clock. The concept of a carbon footprint was decades away when the book was written, but without adding anything for flying reindeer, Santa’s would be close to zero.

As he makes his rounds, we see English farmhouses by moonlight, and my daughter pointed out the details she recognises --- bicycles, water barrels to catch rain from gutters, sticks crossed in the garden for peas to climb. Sometimes Santa has to crawl out of the stove, for people cooked with wood or coal and the oven went to the chimney.


That world was already fading when Father Christmas was published in 1973, and the encroaching modern world seems to confuse Santa. He struggles to find entry into a caravan – a trailer or mobile home to Americans – and he gets tangled in someone’s television antenna. We wondered about things like this as children -- how many of us had ever seen a home with a chimney, much less a sleigh?

The whole story, of course, made more sense when it was gaining popularity in the 19th and early 20th centuries; most children were familiar with sleighs or lumps of coal, and hung their stockings by the chimney anyway, to dry. The oranges we received in our stockings were meaningless to us in the 1970s but precious to our forebears; they were from exotic lands. In “A Visit From St. Nicholas,” Mama was in her kerchief and I in my cap because the houses were cold. Children a century ago would not have found such verses cryptic, any more than they would stables and mangers.

Today it might seem like that world has been completely forgotten. As we inched up the energy needle, our mainstream culture abandoned most of its traditional holidays -- Midsummer, Candlemas, Twelfth Night, May Day and many more – and swelled Christmas from a night to a shopping “season.” Christmas movies and television increasingly portrays Santa’s “workshop” as an assembly line, while news pundits annually track the spending numbers like telethon hosts.

Yet people can’t completely forget a more traditional world this time of year, not amid so many traditions. It is at this time of year that modern people are most likely to visit family, cook food, meet their neighbours, go to church, bring greenery inside, go from house to house singing, or even watch black-and-white movies from the simpler foothills of the energy needle.

When we take pleasure in these things, we peek through cracks in the wall of stress and excess and see another, older world on the other side, and realise that it too can bring comfort and joy.

The End of Childhood

 

Recorded history is the history of adults–generals, statesmen, explorers and scientists–but all of those adults began their path as children. And running beneath this official history is the unofficial history of children, who inhabited a separate universe of traditions, contests, solemn rituals and codes of honour, like a Viking horde living in your house unnoticed. 

It was in this world that every future general first learned to lead, every future scientist first turned over logs to delight in the tiny nightmares underneath, and every future explorer first plucked up the courage to enter the haunted woods. Elderly people here in Ireland, who grew up without electricity or many cars, still remember the feral exploration and creative play that was once the birthright of every child.

“Children today don’t have to think much about games given to them – we made up our own,” said one elder. “We played spin the top, marbles, hoop the hoop, hop scotch, conkers, kick the can, scut the whip, jackstones, and box the fox. Hop scotch has survived to some extent, but only among girls … Even when the dark evenings closed in we played ‘Battle In, Battle Out,’ and ‘Jack jack show the light.’”

The games varied widely from person to person; villages only a few miles away could apparently have very different game-traditions. City streets, perhaps because they drew families from so many rural villages, seem to have been a vast melting pot of such games; when British novelist Norman Douglas published his whimsical overview of the children’s games of London in 1916, he spent dozens of pages–most of the book–just listing games. Not dozens of games, mind you–dozens of pages of lists of games, any of which could be as complex as any video game today and most of which were known to most children.

The games, rhymes, and rituals children invented were so ubiquitous, and so often out of sight of adults, that they were little remarked upon or recorded, and only now, when they have almost disappeared, can we look back and see how remarkable they were. In the 1950s the husband-and-wife team of Peter and Iona Opie interviewed children on playgrounds around the UK and found that, instead of being silly and spontaneous, children’s rhymes and stories actually preserved historical traditions their parents had lost.

“Boys continue to crack jokes that Swift collected from his friends in Queen Anne’s time,” Opie wrote. “They ask riddles which were posed when Henry VIII was a boy. . . . They learn to cure warts . . . after the manner which Francis Bacon learned when he was young. . . . They rebuke one of their number who seeks back a gift with a couplet known in Shakespeare’s day. . . . and they are [perpetuating stories] which were gossip in Elizabethan times.” They re-discovered the observation of Queen Anne’s physician John Arbuthnot, who said that “nowhere was tradition preserved pure and uncorrupt but amongst school-boys, whose games and plays are delivered down invariably from one generation to another.”

This is especially remarkable since most of these rituals were not taught by parents or grandparents, who might have learned them decades earlier, but by other children who could only have known them for a few years. Since they were re-transmitted over years rather than decades, their transmission signal should have decayed more quickly. Instead, the children proved stronger at retaining historical knowledge than most adults–not in the sense of reciting facts, but in treasuring their past.

Some of their superstitions, like a blister as proof of lying, date back at least to the 1500s, and they chanted a rhyme that apparently dates back to the era of France’s Henry IV in 1610. Most interestingly, country children still wore oak leaves or an acorn in their button-holes on 29 May to remember the return of Charles II in 1651–and could explain why they did so–at a time when few adults remembered the date.

Keep in mind, also, that few people were writing in the 1500s, most writing was not about children’s games, and much of what was written then has been lost–so if a ritual was first recorded in the 1500s, it could well be much older. Oral traditions can endure for thousands or even tens of thousands of years; Australian Aborigines have traditions about the sea level changing that seem to date from the last Ice Age. No one knows if any children’s rhymes and games date back so far, but Douglas believed that one chant stretched back to the time of Nero, and the Opies seemed to agree.

Their games and rituals were still very local, even in the 1950s when mass media was already washing away the local cultures of villages and neighbourhoods. “While some children roll eggs at Easter,” the Opies wrote, “or nettle the legs of classmates on the 29th of May, or leave little gifts on people’s doorsteps on St. Valentine’s Day, or act under the delusion that they are above the law on a night in November, other children, sometimes living only the other side of a hill, will have no knowledge of these activities.”

Here, too, Ireland held onto this heritage later than most countries, and a radio documentary of children playing in a Dublin school-yard in 1977 showed them using their own complicated musical chants. They weren’t all local traditions–one chant cited Shirley Temple, “the girl with the curly hair”–but even that showed the staying power of these songs, as this was two generations after she had been famous.

The Opies also noted that children spontaneously adopted a “code of oral legislation”–cultural institutions for testing truthfulness, swearing affirmation, making bets and bargains, and determining the ownership of property–the adult legal code in miniature. These codes universally included a practice absent from adult law, however–that of asking for respite, what we recognize as “calling time out,” and what today’s children reportedly call “pause,” a usage imported from video games.

“Throughout history, bands of children gathered and roamed city streets and countrysides, forming their own societies each with its own customs, legal rules and procedures, parodies, politics, beliefs, and art,” the blog Carcinisation pointed out. “With their rhymes, songs, and symbols, they created and elaborated the meaning of their local landscape and culture, practicing for the adult work of the same nature. We are left with only remnants and echoes of a once-magnificent network of children’s cultures, capable of impressive feats of coordination.”

This seems to have been true of all human cultures–anthropologists report it in hunter-gather tribes, and Zechariah 8:5 said that “the streets of the city shall be full of boys and girls playing.” Certainly it was true among people I knew in Ireland or the USA in living memory. To see how recently outdoor play was assumed, look at a map of most American cities; anything built before World War II is typically a grid for easy transport, but post-war suburban streets curl like tossed spaghetti and end in cul-de-sacs in order to do the opposite, to slow and discourage traffic to be “safe for families.” The sprawl that covers much of America looks the way it does because it was made to be safe for children to play in the street–which in 1945 was exactly what they would be doing.

If the returning GIs who first moved into these homes could be transported to the present day, however, they would be puzzled. Aside from the fact that the future never happened–no flying cars or robot butlers–the most glaring difference would be the absence of any children. To a time traveler it would seem like the beginning of a Twilight Zone episode, and they’d would demand to know what happened–was there a plague? An alien invasion? Are the children grown from pods now? Are they marched to an altar and sacrificed to a dark god? Or is this some horrific science-fiction future where children grow up staring at glowing rectangles, and are drugged when they get restless?

“Even the idea of a children’s game seems to be slipping from our grasp,” Neil Postman wrote in 1982. “A children’s game, as we used to think of it, requires no instructors or umpires or spectators; it uses whatever space and equipment are at hand; it is played for no other reason than pleasure. . . . Who has seen anyone over the age of nine playing Jacks, Johnny on the Pony, Blindman’s Buff, or ball-bouncing rhymes? . . . Even Hide-and-Seek, which was played in Periclean Athens more than two thousand years ago, has now almost completely disappeared from the repertoire of self-organized children’s amusements. Children’s games, in a phrase, are an endangered species.”

The decline began a few generations ago, when television steamrolled over children’s cultural traditions, and that screen has now multiplied into a billion hand-held ones. When children everywhere carry all the world’s pornography in their pocket, as well as electronic games psychologically designed to addict people as powerfully as heroin, few future leaders will organise their mates, and few budding scientists will turn over any logs. Moreover, children today grow up under effective house arrest, as local ordinances, paranoid neighbours and police conspire to prohibit children from venturing far outside. They grow up learning no lessons, organising no peers, and exploring no territory, unless it be shifting electrons around a screen, and the screen becomes their world.

This unnatural state takes all the power of modern society to maintain, and it does not have to be inevitable or permanent; even now some parents keep their children unplugged and gather with other parents who do the same. If they don’t live near the country themselves, they might visit family who do. They teach small children some games from old books, and let the children take it from there. How this guerrilla action proceeds will depend on the situation, but it needs to be done. Otherwise, today’s children will live in a country filled with the most dependent and least self-sufficient humans who ever lived, polarised and paralysed by their screens, and facing a difficult future. We will need a generation of people who can explore, negotiate, and work together again, and to do that we need children to experience childhood once more.
