Street Rod, released in 1989, was set in 1963. It encouraging lawless behaviour on game streets. Note, in particular, the poor quality of the graphics. This was not important on early computers, such as an Amiga, where the best screen resolution was 640×512i (PAL) with 16 colours.
If people think that gaming is a marginal activity, they should reassess their world view. The revenue from computer games exceeds that of the music, film and television industries combined. The production of a game can employ 500 people, many of them engaged in providing different forms of artwork. People under the age of fifty, spend much of their free time gaming. Those over, not so much.
The ten countries with the largest consumption of computer games are, in ranked order: USA, China, Japan, South Korea, Germany, UK, France, Canada, Italy and Brazil. The source for this information provides revenue in USD, and the number of players. In terms of production, 2020, Swedish gaming companies ranked ninth in the world, and generated an annual net turnover of 20.8 billion SEK.
Every game involves a game-world with its own rules, that may differ significantly from the reality the player normally lives in. The better able the player is to adapt to these changes, the better able the player should be able to score, and ultimately to win the game. In many games, there is also an element of chance.
In some games, having control over the graphics (or at least better control than any opponents) is necessary for the player to win. In many games, winning simply means completing the game.
For the record, my list of favourite games has not changed much over the decades, and are not demanding with respect to graphics. In chronological order the ones I remember are: Oregon Trail (1971), Flight Simulator (1982), Where in the World Is Carmen Sandiego? (1985), Sim City (1989), Postman Pat (1989), Street Rod (1989) and Minesweeper (1990). There was also a train simulator, with a forgotten name.
Of these, playing Postman Pat involved the most work. Since it was impossible to obtain an overview map while playing the game, our family visited the entire game world, and recreated the map on paper. For someone with a flawed sense of geography, this was very helpful, possibly allowing me to even beat children, as long as they were very young.
In my teaching career I have used Sim City to introduce the concept of simulation to younger students, most typically a three hour session provided to students at the three junior secondary schools in the Leksvik catchment area. My son tells me that traffic congestion makes it difficult for the game population to exceed about 10 000 people, on a first attempt. He must have inherited his game playing capability from his mother, since he managed to build a city of 150 000 people, on his first attempt.
Non-favourite games include Railroad Tycoon (1990) as well as programs that imitate board and card games, such as monopoly or chess. Railroad Tycoon is less about simulating a transport system, and more about building and managing a company that happens to be a railroad. This is done by investing in track and stations, and by buying and scheduling trains. To win the railroad must be built within a specified time.
To answer the most common question I have ever been asked about computer gaming. Yes, I am acquainted with, but have not played: Minecraft (2009), Pokémon (1996, in card format) or Donkey Kong (1991).
It should now be obvious that I am living in the past with respect to computer gaming. My relationship with board and card games is equally problematic non-existent.
There is one game that I have been considering, NIMBY Rails, which is an open-source transit simulation developed by Carlos Carrasco, from Barcelona, Spain. NIMBY = Not In My Back Yard, which is a common approach to anything requiring change. The game includes content from Open Street Maps, that contains a slightly simplified variant of the entire earth, so that players can construct a transit/ rail system anywhere on the planet. There are detailed rules built into the game that have to been discovered through trial and error. It was launched in 2021.
The first computers used by our family for gaming were an Amiga 1000, soon replaced with an Amiga 2000. Most of the games listed above were first played on it. After that we have owned Windows and Mac machines. With the children becoming adults and capable of making their own decisions, the oldsters use Acer Swift 3 laptops with assorted Asus machines running Linux Mint 21.2. We also have hand-held devices (Asus Zenfone 9) running Android 13.
One of the challenges gamers faced during the pandemic was the lack of GPUs = Graphical Processing Units, usually bought in the form of a graphics card that is inserted into large cases they would call their gaming rig. There are, of course, more portable computers that can be used for the same purpose.
During the pandemic, there was another group of people wanting GPUs: cryptocurrency miners: individuals, companies, organizations, (some criminal and evading paying taxes in any form), who want to use the equipment to produce bitcoins, and other types of cryptocurrency. This production requires enormous amounts of electricity, and these miners want to equip their mining rigs, which look more like servers, with large numbers of the fastest possible GPUs.
For GPU manufacturers this explosion of mining demand created a public relations challenge. The two dominant companies are Nvidia and AMD = Advanced Micro Devices, in previous incarnations, especially their Radeon GPUs. They are now restricting sales of GPUs as add-on products, and prioritize selling them to OEMs = Original Equipment Manufacturers, who put them in new, expensive computers most often designed and labelled as gaming rigs. This created a problem for some gamers, who could/ can no longer upgrade their rigs.
There are several areas where graphic content can provoke conflict. The first is internet throughput, usually measured in k- or M- or Gb/s. An ISP = Internet Service Provider, will provide a range of throughput at various price points, and it will be up to the consumer to decide which one. The current base rate from our ISP is 150 Mb/s, but both 500 and 1 000 Mb/s are available. We have a base rate subscription.
With the onset of Putin’s war in Ukraine, and especially after he stopped/ limited gas sales to Europe, it became economically unviable to mine cybercurrencies! This meant that there was a sudden increase in the number of GPUs on the used market. Unfortunately, not all of these GPUs have a configuration suitable for gamers. Fortunately, Inexpensive former mining-GPUs can be suitable for video-rendering. Unlike gaming machines, rendering machines do not need to connect to a screen. They do not even need to be quiet.
The two next areas involve screen characteristics. Every screen has a specific resolution. In 1988, screen resolution was typically 640×512i (PAL) with 16 colours. In North America, NTSC, the resolution was less. Today (2023), one common resolution is FHD (Full High Definition) = 1920 x 1020 pixels aka 1080p HDTV video format. It has a 16:9 aspect ratio and about 2 megapixels of content. The p stands for progressive scan, i.e. non-interlaced, and is the standard on computer screens. The other dominant standard is 4k UHD (Ultra High Definition) = 3840 × 2160 pixels is the dominant 4K standard, adopted in 2014, with the same 16:9 aspect ratio, and 8 megapixels of content. This, increasingly, is the dominant standard on television sized screens, typically between 40″ = 1 000 mm and 70 inches = 1 780 cm, diagonally.
Human vision varies. A person can process 10 to 12 images per second and perceive them individually. At higher frequency rates these images are perceived as motion. The most common preferred minimum frequency rate is 50 Hz, with that being a common frame rate in Europe or 60 Hz in North America, although some have no problems watching video at 30 Hz. Many gamers, however, are prepared to pay extra for a 144 Hz screen, although I personally don’t think they can improve their perception, by increasing the frequency. The highest frame rate currently available is 240 Hz. While there are some algorithms that can be used to reduce the amount of processing needed, a frame rate of 120 Hz, will require 4 times the processing as a 30 Hz frame rate. Compared to FHD at 50/ 60 Hz, 4k UHD at 120/ 144 Hz, will require 8 x the processing power.
This post is published on the 120th anniversary of the founding of the Marine Biological Association of San Diego on 1903-09-26. In 1912, the assets of this organization were transferred to the Regents of the University of California and renamed the Scripps Institution for Biological Research. In 1925-10, it was renamed the Scripps Institution of Oceanography.
Its mission statement reads, “To seek, teach, and communicate scientific understanding of the oceans, atmosphere, Earth, and other planets for the benefit of society and the environment.”
One of the more interesting vessels at Scripps was Research Vessel Flip = Floating Instrument Platform. It was in service from 1962-07-23 to 2023-08-04, but is now being scrapped. It is often described as an open ocean research platform designed to study various phenomena such as wave height, acoustic signals, water temperature and density, and to collect meteorological data. The vessel has no means of propulsion, because that could potentially interfere with acoustic instruments. Surprisingly, it is equipped with diesel generators. Flip has to be towed to open water sites where it will be used. Once it is in position it is sunk, reaching a depth of 91.4 m. Part of the vessel remains above the waterline, up to a height of about 17 m above the surface. It can then either be allowed to drift freely, or is anchored in place.
For the past sixty years, I have followed the adventures of Flip at irregular intervals, inspired by its ability to collect data. A cheaper way of collecting data is to use a smaller vessel equipped with sensors. Since 1962 there has been major developments in sensor technology. Sensors are now inexpensive, and can be attached to microprocessors. Data can be stored on equally inexpensive solid state devices, that can be fitted onto an underwater vessel.
In robotics, as elsewhere, language is used inconsistently. There are two types of underwater robots, that is, underwater vessels/ vehicles without human occupants, that use two different naming conventions. If the robot is tethered to the surface it is called a ROV = Remotely Operated Vehicle. If it isn’t, it is called an AUV = Autonomous Underwater Vehicle.
In a more ideal world, it should be possible to distinguish between surface watercraft and submersible watercraft. Both categories could be autonomous or in some way human controlled. Tethered craft are not crewed, but remotely controlled by humans. An alternative naming system could refer to two classes of robotic submersibles, the first referred to as tethered (RS-T), and the second as autonomous (RS-A) or even untethered (RS-U). A vessel crewed with humans could be given the name CS = crewed submersible.
My experience with RS-Ts started in 2008 teaching technology to students at Leksvik Upper Secondary School, and using both the community swimming pool and a local beach as launch sites. Build Your Own Underwater Robot and Other Wet Projects (1997) by Harry Bohm (1954 – ) and Vickie Jensen (1946- ), published by Westcoast Words, in Vancouver, provided the inspiration. A copy of this book was found at the Simon Fraser University bookstore, and purchased in the summer of 1997.
Experimentation with a diving bell, teaches the laws of physics as they apply to submersibles. Depending on the power of the airpump, a diving bell is able to rise, fall and even balance itself in a column of water. However, if the diving bell descends below a certain critical depth, the water pressure will be too great for the air pump to work, and the vessel will continue downward without any ability to stop. This surprises most students.
Three of their models, a Diving Bell (powered by an aquarium airpump), Seaperch (powered by thrusters = electric motors) and Seafox (powered by bilge pumps) were made, adapted and remade, repeatedly.
There are numerous commercial and organizational sites that use the Seaperch and/ or Seafox as the starting point for products, competitions and DIY construction. Unfortunately, some are disingenuous, most notably the Seaperch organization, that fails to acknowledge their indebtedness to Bohn/ Jensen. However, the Wikipedia article about the organization does acknowledge this debt. The Bohm/ Jensen RS-Ts have their limitations, particularly in terms of operational depth. Their main purpose is education, both in terms of construction and operation in a marine environment.
Monitoring Equipment
An infinite number of inmates at Verdal prison had, over the years, requested an opportunity to make drones. In particular, they were interested in using these to monitor prison guards. Fortunately/ unfortunately for the guards/ inmates, respectively, no drones were ever made at the prison, at least not when I was working there. When I did offer to teach them how to make underwater vehicles, there was no interest.
Description of the OpenROV Trident.
Thus, when OpenROV was proposed in 2012, it immediately attracted my attention. It took several years (2015), before OpenROV announced a Kickstarter project to build an underwater drone for everyone. They referred to it as Trident, with a purchase price of $1 200 each.
With a length of 300 mm, a width of 200 mm and a height of 150 mm, it is considerably smaller than either a Seaperch or Seafox. It is also lighter, with a mass of about 2.5 kg. However, it has several additional attributes that distinguish it. The first is an ability to reach a depth of 100 m. This makes it almost useful! The depth exceeds that of RV Flip.
A waterproof tube 180 mm long and 100 mm (outside) diameter houses all the electronics and other environmentally sensitive equipment. There are 3 x 800kv brushless motors to power the RS-T. Two horizontal thrusters allow the RS-T to move forward and aft as well as rotate, and a vertical thruster allows the (neutrally buoyant) vehicle to change depth.
The trident is the weapon of the gods of the Sea: Greek Poseidon, or Roman Neptune as well as Amphitrite, Greek queen of the sea and consort of Poseidon. In Roman mythology she is referred to as Salacia, with a reference to salt. In both sets of myths, Triton, another Greek as well as Roman god of the sea, is the son of Poseidon/ Neptune and Amphitrite/ Salacia. Triton is a merman with a human upper half, and a fish/ lobster/ crayfish lower half. In Hinduism, Shiva also uses a trident, referred to as a trishula.
Ægir (Æge in modern Norwegian) is the Norse god of the sea. He does not appear to have a weapon, but spends his time brewing beer. He is married to Rán (Rån in modern Norwegian), goddess of the sea. Together they have nine daughters, the waves.
One of my intentions when I worked at setting up a mechatronics workshop in Inderøy, was to provide an opportunity for the production of equipment to monitor the environment. At the time I was particularly interested in unmanned underwater vehicles, to discover local sources of pollution. Inderøy library has now taken over this workshop.
Thus, my own little workshop will have to become a local skunk works, producing not only vessels, but slower, lower altitude incarnations of a U-2 Dragon Lady or SR-71 Blackbird, in the form of a drone.
Lockheed took the name Skunk Works from Li’l Abner’s moonshine factory, where it was known as Skonk Works, found in the comics written and drawn by Al Capp (1909–1979), from 1934 to 1977. For those too young to be acquainted with the comic strip, Li’l Abner Yokum, was the son of Pansy Hunks aka Mammy Yokum and Lucifer Ornamental Yokum aka Pappy. They lived in a log cabin in Dogpatch, USA. The location of Dogpatch is disputed, but most place it in Kentucky. One of the wimmenfolk there was the beautiful Daisy Mae Scragg, who married Abner in 1952. Sadie Hawkins was another notorious resident, not quite so beautiful, but intent on marrying. Some of my fascination with names as well as fictitious geography comes from comic strips. In addition to Li’l Abner, Pogo by Walt Kelly (1913-1973) also provided some interesting geographical features in Okefenokee Swamp, located in southern Georgia and northern Florida.
Currently, I have a workshop that supports my construction activities by producing components in wood. While I have not given up the idea of producing wooden products entirely, especially geodesic dome greenhouses, I have also acquired a small computer numeric control (CNC) milling machine, for subtractive processes. One intended use of this machine is to make parts for a RS-T. I also have a 3D-printer for making parts using additive processes.
In the past, I have used the non-descriptive name, Unit One, for this workshop. My own name, Brock, means badger, so it is not inappropriate to rename this workshop the Badger Works, but also incorporating the Norwegian language equivalent, Grevlingverket. From 2024-01-01, I intend to spend time designing and making a RS-T and surface/ support unit, suitable for investigating pollution in Trondheim fjord. The names Ægir and Rán will probably be incorporated into the names of these vessels.

Fifty years ago, back in the 1970s, I practiced a form of transcendental meditation. This weblog post provides some basic information about it, along with lists of mantras. I am referring to this content as open-source meditation. It comes without any guarantees. While there are undoubtedly differences of opinion, I do not think most people need a guru, or any form of instructor in order to meditate. People who disagree about this, or other matters, are encouraged to provide enlightenment, by writing a comment.
Among the books I am currently, but reluctantly, reading is Johann Hari (1979 – ) Stolen Focus: Why You Can’t Pay Attention – and How to Think Deeply Again (2022). Hari has had a history of ethical issues, including plagiarism, related to journalism, and like much of his work, this book has also received criticism. The topic of the book is important, and there is no harm in reading this book, as long as one is aware of its limitations.
While reading this book with respect to the challenges of multi-tasking, as well as sleep deprivation, I began wondering if other animals also suffered from these problems. Crows, I recently learned, are capable of using probability. This is why a photo of a bullfrog appears. Is it a secret meditator? I also wondered if some form of meditation could be useful, for aging humans, such as myself.
Claimed benefits of Meditation
Physical
Improved cardiovascular health: Studies have shown that TM can help reduce blood pressure, improve circulation and increase oxygen flow to the heart.
Reduced response to pain
Reduced insomnia and improvement in sleep: TM has been linked to an increase in the production of melatonin – a hormone thought to be responsible for promoting good sleep.
Mental Health
Reduced stress and anxiety.
Reduced symptoms of depression.
Cognitive
Increased focus and concentration.
Increased productivity and creativity.
Improved short-term and long-term memory.
Emotional
Improved emotional regulation and resilience.
Improved self-awareness
Improved self-confidence
Improved emotional well-being and happiness
Preliminaries
Choose a mantra. Mantras help the mind enter a state of inner stillness and peace, preventing active thinking. Select one that resonates with you. A number of mantras are listed below. Choose a location for meditation. It should be a place where you won’t be disturbed. Twenty-first century reminder: switch off that hand-held device that accompanies you, or put it on silent mode.
Meditating. First, sit comfortably. The spine should be upright but not rigid. The back can be supported. Second, close eyes. Third, silently repeat a mantra. Some forms of meditation use mantras that are religious words, typically with origins in Sanskrit. Others use sounds without any meaning. The advantage of a meaningless mantra is that it is easier to switch off thoughts. Meditators often claim that they enter a state of deep relaxation. Fourth, continue for twenty minutes.
Conclusion (once the 20 minutes are up). First, slowly open your eyes. Second, bring your attention back to your surroundings. Third, take some deep breaths and slowly stand up. Fourth, the real world awaits you. Return to whatever needs to be done. Fifth, remember to meditate twice a day.
Sleep Meditation
Meditating to help a person to sleep requires modifications to be made to the standard procedures. Instead of sitting, continue to lie down on your bed. Allow your body to sleep if and when this is possible.
Walking Meditation
Some people are not particularly good at sitting still. They may prefer a walking meditation, where they can develop an awareness of their surroundings and, in so doing, calm the mind and relax the body.
Find a safe place to walk.
Start to walk slowly.
Pay close attention to the physical sensations of walking: the way your feet feel when they touch the ground; the way your muscles contract and release as you move; and the rhythm of your breath.
Possibilities: Notice the air on your face and hands. Notice how the humidity and heat feel on your body.
When your mind wanders, gently bring attention back to your body and to the physical sensations of walking.

Other mantras are words or sentences in Sanskrit. These include: 1) Om (or Aum) is the prime symbol of Hinduism and one of the most important spiritual sounds. It is the sonic representation of the divine in Indic traditions. It is often chanted during spiritual recitation or used as a mantra during meditation in Hinduism, Buddhism, and Jainism. 2) Sat Nam is a combination of two ancient Sikh words, “Sat” meaning “truth” and “Nam” meaning “name” – essentially it means “I am truth”. 3) Om Mani Padme Hum is a Buddhist mantra to invoke the blessings of Avalokiteshvara – the bodhisattva of compassion. It’s commonly translated from Sanskrit as, “The jewel is in the lotus.” 4) Ra Ma Da Sa is a Kundalini yoga that combines four sounds to create a positive vibration that helps release stress and tension as well as to bring balance to the body and the mind: “Ra” represents the sun and the masculine energy; “Ma” represents the moon and the feminine energy; “Da” represents the Earth and the healing energy; “Sa” represents infinity and the enlightenment energy. 5) Aad Guray Nameh is a Sikh meditation mantra meaning, “I bow to the primal wisdom”: Aad Guray Nameh = I bow to the Primal Wisdom, Jugaad Guray Nameh = I bow to the Wisdom of all the ages, Sat Guray Nameh = I bow to the True Wisdom, Siri Guroo Dayvay Nameh = I bow to the Great Invisible Wisdom.

My son, Alasdair, and I arrived at the airport on Vágar, on Monday, 2023-07-10, for a short adventure that will last until Friday, 2023-07-14. After picking up our rental car, a Hyundai Kona diesel with manual transmission, we headed off towards the neighbouring island of Streymoy!
Unlike Iceland, which met us with desolation, we were met by fog which helped us suspend our judgement. We soon stopped at a food store, where we encountered three young workers who, true to tradition, complained about their elders. They were helpful, and we were able to purchase necessities for our domestic life.
We took the easy way out buying coffee that was already ground. The food store had a machine to grind coffee beans.
We then continued on to our accommodation at Kvivik, run by Petra Iversen. It was a comfortable basement suite, suitable for two people.
Domestic necessities
Healthy eating? Puffed wheat coated with honey and sugar, along with orange flavoured yoghurt.Safely stored in a freezer, two varieties of ice cream chocolate and licorice.We took the easy way out buying coffee that was already ground. The food store had a machine to grind coffee beans. Indeed, we later found that our hostess had a coffee bean grinder in her kitchen. This took me back to the early 1980s, when Trish worked at a coffee and tea store that ground coffee to the specifications of its clients.
Alasdair noted, correctly it turned out, that our accommodation had been outfitted by a woman. Appliances included a filter coffee maker and kettle, microwave oven, conventional oven, induction stove top, freezer and refrigerator, as well as a dishwasher and a battery operated, bagless vacuum cleaner. Dishes, plates, glasses, cups and flatware were found in abundance, in the cupboards. I especially liked her red, rubberized coffee cups. This place felt more like home, than any other place we had stayed in previously on this trip.
On Tuesday evening, we met our hostess, to pay for our accommodation. She had a coffee bean grinder in her kitchen. This took me back to the early 1980s, when Trish worked at a coffee and tea store in Molde that ground coffee to the specifications of its clients.
The coffee cup, turned upside down.Tvis Køkken = kitchen, from Holstebro, Denmark.
On this trip I have decided that my role is to look at culture rather than nature. Thus, I was delighted to find two works of art from our accommodation that are included here for everyone’s enjoyment.
On our last evening, we were given a sample of Faroe cuisine, complete with whale blubber and mutton.
I do not follow sports, but sometimes read results so that I can interact with normal people. There are two counrties that are natural for me to support, Canada and Norway, not to mention Ireland, that has provided citizenship to the others in my immediate family. With the Women’s World Cup, I felt I could impress these people by reporting a select few game results. Already near the start, on 2023-07-20, with Norway losing 1-0 to New Zealand, and Ireland losing 1-0 to Australia, I realized that backup could be necessary, in order to be on the winning side. Fortunately, Denmark and Sweden were also playing. By the end of group play, Canada and Ireland were out, but the Scandinavians were still in. On 2023-08-05, Norway lost 3-1 to Japan, and was out. The next day, Sweden beat USA on penalties, and was still in. The day after that, Denmark lost 2-0 to Australia. All hopes were on Sweden. In the end, on 2023-08-19, Sweden ended up in third place. On 2023-08-20 Spain won with England in second place. The scene was set for the main drama…
Dear Luis Rubiales: sportswomen are not dolls to be kissed, touched and patronised. Those are the words of Barbara Ellen in The Guardian.
Yes, I eagerly awaited the resignation of Luis Rubiales (1977 – ) for forceably kissing Jenni Hermoso (1990 – ), a Spanish professional footballer who plays for Liga MX Femenil club CF Pachuca (Mexico) and for the Spain women’s national team. She has previously played for teams in Spain, including Barcelona, and is the all-time top scorer for both Barcelona and Spain, at the end of the Women’s World Cup. She did not consent to be kissed.
Rubiales is president of the Royal Spanish Football Federation (RFEF) and one of the Union of European Football Associations (UEFA) vice presidents. He refused to resign, and was dumb enough to say, “A social assassination is taking place. I don’t deserve this manhunt I have been suffering.” It took Fédération Internationale de football association = FIFA to remove him, if only temporarily. FIFA will look at whether his actions constitute violations of Article 13 in its disciplinary code, concerning offensive behaviour and fair play.
The Spanish government was also taking action to force his removal. It was asking Rubiales to explain himself to a Spanish administrative court as soon as possible. If it deems he violated the professional sports code, he could then be suspended.
Hermoso stated: “I want to make clear that at no time did the conversation to which Mr Luis Rubiales refers to in his address take place and, above all, his kiss [was n]ever consensual.”
She added his claims were “categorically false and part of the manipulative culture that he has generated”.
“I feel the need to report this incident because I believe no person, in any work, sports or social setting should be a victim of these types of non-consensual behaviours. I felt vulnerable and a victim of impulsive-driven, sexist, out-of-place act, without any consent on my part”.
“Quite simply, I was not respected.”
She was put “under continuous pressure” to help with a “statement that could justify” Rubiales’ actions – and so were her family, friends and team-mates.
“These types of incidents add to a long list of situations that the players have been denouncing. This incident is the final straw and what everyone has been able to witness on live television also comes with attitudes like the one we saw this morning [Friday, 2023-08-25] and have been part of our team’s daily life for years”.
81 players confirm they will not play for Spain’s women’s team until he is removed from his post. In addition, two Spanish men’s national team and Real Betis players, Héctor Bellerín and Borja Iglesias, criticised Rubiales on social media, with the latter refusing to play for Spain until Rubiales resigned.
By Saturday, 2023-08-26, RFEF had threatened to sue Jenni Hermoso, accusing her of lying and defamation, and the women football players who signed a letter in which they refused to play for their country as long as Luis Rubiales remained its leader. Obviously, a lot more people in the RFEF need to be replaced.
Then, Ángeles Béjar (? – ), Rubiales’ mother, entered the Church of the Divine Shepherdess in Motril, Granada, Spain on Monday morning, 2023-08-28, to begin a hunger strike to protest what she describes as her son’s unwarranted, inhumane and bloodthirsty hunt.
2023-09-11 Update:
Ángeles Béjar was taken to hospital on 2023-08-30.
On 2023-09-05, Jorge Vilda (1981 – ) was fired as head coach of the Spanish women’s national team.
According to a Guardian article, Luis Rubiales’ uncle, Juan Rubiales, told El Confidential: “We Rubialeses are absolutely committed to the idea of dignity. And dignity is to defend Jenni, to understand her, and to reproach the shameful behaviour of this president…. I think [Luis Rubiales] needs a social re-education programme and a re-education in his relationship with women.” He described his nephew as a man “obsessed with power, luxury, money and women”. In a separate interview with the newspaper El Mundo, he added that his nephew was a “man with a clear machista [sexist] tinge”.
Irene María Montero Gil, MP is a Spanish politician and psychologist, member of the Podemos party. She has been the Spanish Minister of Equality since 2020-01-13. She described the kiss as a “lower-intensity” form of sexual violence that is often invisible and normalised in society.” On 2023-09-10 she tweeted: “Se acabó [It’s over].”

Rich Men North of Richmond
Oliver Anthony, playing Rich Men North of Richmond
At the start of the first American Elephant Party television debate on 2023-08-22, an excerpt was played of Oliver Anthony’s (1992 or 1993 – ) song, Rich Men North of Richmond, then discussed. Fox News host, Martha MacCallum, said Anthony’s “lyrics speak of alienation, of deep frustration with the state of government and of this country. Washington DC is about 100 miles north of Richmond.”
On stage stood seven current or former governors and congressmen and one venture capitalist, all members of the Elephant Party.
McCallum asked: “Governor DeSantis, why is this song striking such a nerve in this country right now?”
Ron DeSantis, replied: “Our country is in decline. This decline is not inevitable. It’s a choice. We need to send [Donkey Party member and US president] Joe Biden back to his basement and reverse American decline.”
However, on Friday 2023-08-25, nonpartisan Anthony released a 10-minute video, in which he rejected that answer and denied that he was a conservative figure. “The one thing that has bothered me is seeing people wrap politics up in this. I’m disappointed to see it. Like, it’s aggravating seeing people on conservative news try to identify with me, like I’m one of them. That song has nothing to do with Joe Biden. You know, it’s a lot bigger than Joe Biden. That song’s written about the people on that stage and a lot more, not just them.”
It was hard, Anthony said, to “get a message out about your political ideology or your belief about the world in three minutes and some change. But I do hate to see that song being weaponized, like I see. I see the right trying to characterize me as one of their own. And I see the left trying to discredit me, I guess in retaliation. That’s got to stop.”
He said the response to his song had crossed party lines and that he welcomed a diverse audience.
“If you watch the response videos on YouTube, it’s not conservative people responding to the song. It’s not even necessarily Americans responding to the song. I don’t know that I’ve seen anything get such positive response from such a diverse group of people. And I think that terrifies the people that I sing about in that song. And they’ve done everything they can in the last two weeks to make me look like a fool. To spin my words. To try to stick me in a political bucket.”
Wikipedia tells us, that Anthony is the first songwriter to debut at the top of the Billboard Hot 100 with no prior chart history in any form, Anthony is the first male songwriter to chart 13 songs all simultaneously in the top 50 Digital Song Sales while still alive—Prince and Michael Jackson exceeded that count only following their deaths.
Confession 1: I have not actually listened to Oliver Anthony’s track. After about 10 seconds I find the raspy voice and Piedmont dialect , along with a resonator guitar so unpleasant that I turn it off. I was able to listen to Johnny Cash (1932 – 2003), or more likely his artificial intelligence alter-ego, singing it.
Confession 2: I find the names of political parties difficult to accept. I am not sure what makes, say, the Democratic party, more democratic than another party. I frequently avoid that aspect of political debate, by codifying their real names. In this alternative universe, the party that is closest to me is the Marmot party. Why? The marmots I know best, those living on McArthur Island in Kamloops, British Columbia are enthusiastic and engaged, but without direction. I often rename parties after party symbols.
Wildfires
The effects of the Lahaina, Maui, Hawaii wildfire. Photo: 2023-08-17 at 10:02, taken by Glenn Fawcett, for the United States Department of Homeland Security, and released into the public domain.
Wildfires have become an issue. To call them a serious problem is to undermine their destructiveness. I think especially of the village of Lytton in British Columbia, but also Yellowknife in the Northwest Territories, not to mention Lahaina, on Maui. On 2023-08-19, West Kelowna, across Okanagan Lake from Kelowna, where I spent most of my childhood summers, was experiencing wildfires. Kelowna, was being threatened by them. They experienced the wildfire of a century twenty years earlier, on 2003-08-16. Yes, I too am amazed at how short centuries have become!
We have to improve the terms used to describe wildfire events, removing the time scale. A once in a century fire, could be more accurately described as a 1% chance wildfire event. This, has now become a more common 5% chance wildfire event. In another ten years that might increase to a 10% chance wildfire event. These percentages indicate that there is no regularity to these events.
Historically, there have also been large wildfires in the past, such the Peshtigo fire in Wisconsin in 1871 and the Sudbury fire in Ontario in 1916. At times in Australia, Indonesia and other places there have seen multiple fires burning simultaneously, causing significant harm and loss of life. Cities have also burned, notably, the Great Fire of London on 1666-09-05 and Chicago, that started the same day as the Peshtigo fire, 1871-10-08. New Westminster, where I grew up has experienced two massive fires that started on 1898-09-10 and 2020-09-13, respectively.
While I avoid expletives, I am thinking of introducing one for dramatic effect, combustion! (with variants). For example, “It was a combustive mess”. Like most other expletives, it adds no truthiness to a basic statement. Here, a mess is a mess. Combustive simply adds emotional flavour. While some forms of combustion are necessary, the world in my lifetime has produced too much of it. My hope is that by making it an expletive, people will reflect on their combustive behaviour and reduce or eliminate it.
Despite being as much of a NIMBY (not in my backyard) as the next person, I am a proponent of decarbonization, including the total elimination of fossil-fuels, such as natural (and unnatural) gas from houses. Induction stovetops are a more effective (but not necessarily cheaper) way to cook. Hydro, geo-thermal, solar and wind are effective ways of producing clean electricity.
Hawaiian Electric irresponsibly claimed that they could not turn off the electricity on Maui because some customers were dependent on electrical power for medical devices. In addition Maui uses electricity to provide water for residents. My reply is that batteries have been invented that can provide power to medical devices, in situations where it is unsafe to have grid power on. Yes, I am aware that someone has to think of that solution, and that batteries cost money. So does an enormous loss of life, with so many people unaccounted for! Where I have lived water relies on reservoirs and tanks at higher levels, and uses gravity feed to provide water to consumers. Admittedly, water may have to be pumped into these storage places.
Somewhat later, I received the following reply from a friend: Appears Hawaii Utility removed downed power poles, equipment, suspected of possibly causing the devastating fire …. therefore jeopardizing offficial investigation. Cover up?
Maui County is suing Hawaiian Electric over the fire that leveled Lahaina, The lawsuit includes a demand for a jury trial. It alleges the destruction could have been avoided if power lines had been shut off. This is part of a growing critical focus on the utility with videos apparently showing downed cables setting fire to vegetation. There were ample warnings of strong winds from a nearby hurricane, but Maui County claims which that Hawaiian Electric and its subsidiaries negligently kept power lines live. Some quotations: “These power lines foreseeably ignited the fast-moving, deadly, and destructive Lahaina Fire, which completely destroyed residences, businesses, churches, schools, and historic cultural sites.”; “Defendants knew that the high winds the [National Weather Service] predicted would topple power poles, knock down power lines, and ignite vegetation.”; “Defendants also knew that if their overhead electrical equipment ignited a fire, it would spread at a critically rapid rate.”
Maui County is not free of blame. Critics say it was not prepared for the event, and provided an inadequate response. In other place, such as California, electric utilities routinely shut down large stretches of above-ground power lines in strong winds. One has to question whether above-ground power distribution is suitable in the 21st century.
This 2023-08-08 fire was the deadliest wildfire in the United States for more than a century. It burned through about 800 hectares destroying the historic town of Lahaina, a former Hawaiian royal seat. It has rendered thousands of people homeless. Maui County released a list of 388 names of people who remain unaccounted for. Recovery is expected to take years. Federal estimates suggest the fire caused $5.5 billion of damage.
Popularity contests
At the end of August, Tim Anderson has written something I could never write, It has to do with the popularity of computer languages. This topic is easiest to explain by looking at fruits. Different fruits have different uses. Personally, I avoid apples and cherries because they don’t like me. I do consume citrus fruits, but they are not substitutes for each other. I would never eat a lemon or a lime with breakfast, like I would eat an orange or half a grapefruit.
Computer languages also have different uses. I regard scripting languages, such as JavaScript or Lua, as a type of glue, typically used to hold the components of websites together. There are database languages used to manipulate and organize data. In my mind, these are special purpose languages to be used restrictively, much like lemons or limes are used in cooking.
Then there are general programming languages, that can actually be used to make a software product. These are a totally different ilk, much like an orange or (for some people) an apple or a handful of cherries. There have been many generations of these, with Python being the most popular today. It was named after the British comedy group whose first name is Monty, rather than a snake. It first appeared in 1991. C, the language I use most, first appeared in 1972. Fortran first appeared in 1957.
I am now changing the advice I am giving to young people about which general purpose language to learn and use. My new favourite is Rust, named after the plant pathogenic fungi (order Pucciniales) with about 7 000 species. This programming language first appeared in 2015, but originated some years earlier at Mozilla, makers of the Firefox browser. It is supported by a number of large tech companies including Alphabet (Google), Amazon and Microsoft. Apple uses Swift, a competing language and successor to Objective-C, in most areas, but uses Rust in robotics.
On Monday, 2023-07-10 it was time to leave Iceland, and to head to the Faroe Islands. Excitement that morning consisted of an earthquake warning, followed almost immediately by a few earth-shaking moments that appeared to do no damage. We were up and showered before breakfast at 8:00, with a departure at 8:30, in order to return our rental car before the 10:30 deadline. The only problem was that our flight’s departure was delayed by four hours. So we had lots of time to explore the town of Keflavik.
A minor volcanic eruption had already begun as we drove across the Reykjanes Peninsula. We were told that no volcanic ash has been emitted, but noticed an unusual mist as we approached Keflavik Airport. Later, we learned there was a 200-meter long fissure on the slopes of the Litli Hrútur mountain, from which lava emerged as a series of lava fountains.
Unlike the day when we first rented our car, there were more staff than customers at the Budget/ Avis airport office. Alasdair reported the broken windshield, and paid the deductible for the damages. His travel insurance later refunded this amount.
We spent much of our time in Keflavik visiting a municipal park. Photos on our way there are shown below. There were many children in the park, and their activity of choice seemed to be standing in front of robotic lawn mowers, waiting for them to stop, then turn to avoid the human obstruction.
Later, we also walked into the business district, where we found a store that sold flags large enough for our flagpole, a typical souvenir for us. We were surprised to find that it was cheaper to buy an Icelandic flag in Norway, than in Iceland.
Necessities: Microwave communications tower, and water tower
Höfn is the Icelandic term for harbour. It is also a place in the south-east of Iceland, which has a model of the solar system. This weblog post is about this model. It is fairly accurate in terms of relative distance between solar system bodies, with the exception of the location of Pluto.
There are several characteristics to enjoy about a model like this. One of the most important is that it can be reproduced almost everywhere in the world. So, you too could create one, at a smaller scale in a room or garden, or at a larger scale across your county/ state/ province/ country. In this particular case, it is 2.8 km long. However, it could be any length desired. Then there is the data, with all sorts of interesting facts about the sun, and each planet. An example is the sun’s diameter in real life (1.4 million km = 1.4 Gm), and on the model (45 cm). The solar system model bodies are illustrated in two different ways. There is a photographic representation, as it would be seen through a telescope. There is a more naive representation, made by a pupil at the local school.
Not everyone is able to respond to scaled proportions appropriately. I remember one test to see if people understood the scale of the universe. Ask them if the moon or an elephant is larger. I thought it was a dumb question to ask, until one person seriously replied that an elephant is larger.

Weaknesses. I may criticize others for not knowing the true size of the moon. Yet, I have my own failings. No one would describe the photographs of the solar system information panels as professional. They were taken with a smart phone on a sunny day, which meant that because of my light sensitivity, I had to wear sunglasses while photographing them. Most of the time, I failed to capture the entire sign. Even when I did, it was not centred.
I explored the first part of the solar system, closest to the sun, with others, then went out on my own to explore the rest of it, some hours later. I was able to trace it, but unable to retrace the route back to our accommodation. I hadn’t recorded the accommodation address, so had no reference point to use on my smartphone map. Fortunately, I was able to give my location to Alasdair, who rescued me. It was totally undramatic. Yes, I may understand scale, but I don’t have a geographic sense of position, a fact well known to the others in my family.
Venturing into Seyðisfjörður involved about 20 km of driving in fog. While there, much of the fog lifted, so the return drive only involved about 10 km of fog over the 600 m high Fjarðarheiði mountain pass.
The area has a history dating back to the tenth century. It has also been the site of the world’s first modern industrialized whaling station, established in 1864. In 1906, the first telegraph cable connecting Iceland to Europe (and the world) made landfall here. In 1913, it was also the location of Iceland’s first high-voltage AC power plant, that included a hydroelectric dam. During World War II, it housed a British/ American military base.
While for most of the post-war period the economic focus was on fishing, today, it is tourism. the Icelandic port for the Smyril Line ferry M.S. Nörrona, built in 2003, that connects Iceland with Hirtshals, Denmark and Tórshavn, in the Faroe Islands.
The village was also a filming location for the Icelandic crime series, Trapped.
On 2020-12-18, the largest landslide in an Icelandic residential area hit, destroying thirteen houses and the Technical Museum of East Iceland! Many other buildings also suffered damage. Within hours, the entire village was evacuated.
Now, near the Smyril ferry terminal, a display explains the landslide in detail, especially the fate of individuals, complete with photographs by Katja Goljat and Matja Rust.

HyMotion is the name Volkswagen applied to its hydrogen fuel cell prototypes. This post is mainly about Volkswagen, a company that was forced to transition to electric vehicles, because of Diesel-gate. The American Environmental Protection Agency (EPA) , had found that Volkswagen had intentionally programmed turbocharged direct injection (TDI) diesel engines to activate their emissions controls only during laboratory emissions testing, which caused the vehicles’ NOx output to meet US standards during regulatory testing. However, the vehicles emitted up to 40 times more NOx in real-world driving.
About the same time, concerns about the danger of global warming led many countries to set up a timeline to phase out fossil fueled vehicles. It is actually a case of too little, too late. The European Union seemed to be heading in this direction, but then on 2023-03-28 it approved legislation ending sales of new carbon-emitting cars by 2035, but made an exception for E-fuel based internal combustion engine (ICE) cars, due to lobbying from Germany. That means ICE cars will continue to be available for sale after 2035, but will need to be fitted or retrofitted with fuelling inducement system technology to prevent the use of fossil fuels. E-fuels are synthetic fuels, regarded by some as carbon neutral because they are produced by capturing CO2, which offsets the emissions from usage. Carbon neutrality is not always the case. In contrast, hydrogen vehicles emit water vapour and warm air, while BEVs have zero tailpipe emissions.
The challenge is that billionaires, and other wealthy people immediately under them in terms of class, want supercar toys, powered by E-fuels. What E-fuel advocates either fail to understand, or more likely are not concerned about, are the dangers of combustion on living creatures, particularly the role of PM 2.5 particulates. In addition, vehicular noise pollution also becomes an issue, as people seek quieter cities, and other places to live.
After the Diesel-gate scandal broke in 2015, Volkswagen saw electrification as a way to redeem itself. New fossil-fueled light vehicles will not be available for sale after 2024-12-31. Many brands, including Hyundai, have already stopped selling ICE vehicles. Volkswagen in Norway will not sell them after 2023-12-31. Already now, almost 90% of light vehicle sales are battery EVs. Hydrogen vehicles are sold, but in insignificant numbers. I am not certain if Norway is following EU regarding E-fuels. However, there will be social pressure exerted on any potential E-fuel users, who will be seen as violators of the Norwegian social contract.
The motivation to write this post, followed an announcement by Volkswagen Group Chief Executive Officer (CEO) Oliver Blume (1968 – ), that the group would transition to hydrogen powered vehicles, after 2030! Previously, 2022-07-03, Blume had supported E-fuels as an effective, complementary solution to making cars cleaner. “Combustion engines can be powered with e-fuels in a virtually carbon-neutral manner. They don’t have to be converted or retrofitted for it. E-fuels can be offered as an admixture or alone at all filling stations. We have to offer an option to the owners of existing vehicles too.” This misses the point that combustion makes a major contribution to debilitating heath issues through the release of PM 2.5 particulates. It also shows his background as CEO of the Porsche division.
In addition, Blume seemed to be more concerned about the economic health of fuel providers. “If produced on an industrial scale, prices of less than $2 per litre could be possible. The important thing is that synthetic fuels are produced sustainably and in places in the world where renewable energy is abundant – then the higher energy input for production is irrelevant. E-fuels produced from water and the carbon dioxide extracted from the air for automobiles, planes and ships have the advantage over pure hydrogen that they can be transported more easily.”
Ballard Power Systems of Burnaby, British Columbia has developed technology for hydrogen fuel cell products, including membrane electrode assembly, plate and stack components. On 2015-02-11 it sold its technology for light vehicles to Volkswagen Group, but retained the rights to this technology for buses and non-automotive uses. Volkswagen introduced its Ballard based technology to the world in the form of four Volkswagen and Audi fuel cell concept vehicles at the Los Angeles auto show in 2014-11.
Since then, Volkswagen has gone on to develop further fuel cell technology. German patent DE 10 2020 119 021 B3 was issued on 2021-07-29 to Volkswagen and Kraftwerk Tubes. It involves a ceramic fuel cell membrane. Allegedly, this is cheaper to manufacture than a polymer membrane, as found on Toyota and Hyundai fuel cell vehicles. It works without any need for an expensive platinum electrocatalyst. Volkswagen states that this will allow them to produce vehicles with a 2 000 km range.
Volkswagen brand’s CEO Thomas Schäfer (1970 – ), said that E-fuels were unnecessary noise, and that hydrogen has some big disadvantages compared to battery technology and that it’s not for Volkswagen, at least not in the next ten years because it is not competitive, especially not for passenger cars, as the fuel tanks take up space in the cabin.
Still earlier, Blume’s predecessor Herbert Diess (1958 – ), criticized H2 fuel cell vehicles, referring to a report from Potsdam Institute for Climate Impact Research (PIK) that concluded hydrogen vehicles are not the way to achieve climate neutrality. Battery electric cars (BEVs) are more sustainable and can be a more environmentally-conscious option for those who are concerned about their car’s emissions.
A move to H2 fuel cells and away from batteries does not seem to be the smartest move, for several reasons. While there are a certain number of early adapters, most of these interested in alternative vehicles have already taken the EV leap/ plunge, finding it a more appropriate solution for themselves than a H2 fuel cell vehicle. This is mainly an operating cost issue, but also a space issue, but increasingly a model availability issue. There are few fuel cell vehicle model choices. EVs have become dominant, with models suitable for a variety of use cases. People are unlikely to reassess their preference for EVs, especially considering that the operating costs of a H2 vehicle are several times higher than that of an EV. Of course, there are others who are brand loyal, irrespective of how stupidly the company they support acts. In Norway, when an EV needs charging, it is typically plugged in at 22:00, when energy prices are lowest. By morning, it is “fully” charged, typically to 80%, to preserve battery life.
A key word is convenience. In much the same way that workers find it more convenient to work at home, and are reluctant to return to the office, most electric vehicle operators find it more convenient to charge at home, and are reluctant to return to a fueling station. Home charging is a habit that grows quickly, especially when commercial high-speed charging is expensive, and offers no to few advantages. H2 is even more expensive.
A previous post discussed the colours of hydrogen, the assorted types of H2 available, based on how it is produced. About 95% of that H2 is methane based, meaning that it is essentially a fossil fuel, that produces CO2. Other types/ colours of H2 are more environmentally friendly, but with the power produced costing about three times more than electrical power from other sources such as wind, solar or hydro. Given a choice, I doubt if consumers would be willing to pay this for this fuel, given the availability of cheaper, more environmentally friendly alternatives (read: BEVs).
In 2023-06, three H2 stations in South Korea received contaminated black hydrogen, produced using steam methane reformation (SMR) — from Korea Gas’ Pyongtaek facility. Proton exchange membrane (PEM) fuel cells used in hydrogen-powered cars need H2 with a purity of 99.9% to safely operate. SMR produces hydrogen (H2), carbon monoxide (CO) and carbon dioxide (CO2). A water-gas shift reaction is usually turns the CO into CO2, while the CO2 is removed using pressure-swing adsorption. In this particular case, some CO or CO2 may not have been properly removed. These impurities can cause irreversible damage, necessitating the replacement of the PEM and other components. For example, CO adsorbs strongly on the platinum electrocatalyst, and CO in hydrogen fuel degrades the performance of the polymer electrolyte fuel cell (PEFC).
On 2019-16-10, an explosion destroyed a Uno-X hydrogen fueling station at Sandvika, near Oslo, Norway. This was covered in one post initially, then followed up in a second post, some two weeks later. More recently on 2023-07-18, hydrogen buses were being fueled at a Golden Empire Transit facility, in Bakersfield, California when one of the buses caught fire. One bus was destroyed and the dispensing portion of the hydrogen fueling station damaged.
In the world there are about 625 public hydrogen fueling stations, according to one source. At the top of the list are: Japan with 175, USA with 107, Germany with 92, China with 88 and France with 40. In Canada there are 8, of which 6 are located in British Columbia (Burnaby, Kelowna, Marpole in Vancouver, North Vancouver (2) and Victoria). There is also one in Mississauga, Ontario and another in Quebec City, Quebec. In Scandinavia, Norway and Denmark have 7 each, Sweden has 5, Iceland has three, while Finland has none. There is actually one located 124 km (1h 51m driving time) south of Cliff Cottage. It is the most northerly in Norway. Except, a Norwegian source states that there are only three H2 fueling stations currently operating in Norway! Interested readers can take it upon themselves to find the correct number of H2 fueling stations in the world. It is probably over 500, but less than 1 000. Currently, one source indicates that there are about 115 000 gas stations in the USA.
Ammonia (NH3) has also been suggested as an energy bearer. This will not be discussed here, except to reference a source for further information.
If Blume is wanting to shift to fuel cells to increase range, he should be aware that researchers at Pohang University of Science & Technology in China have found a way to multiply the energy storage of a battery by ten. An anode stores power when charging and releases it to provide power. Currently, most modern lithium batteries use an anode made of graphite. Other materials, like silicon, have a higher energy capacity, but researchers have been unable to create a stable battery with a silicon anode. This is because the reactions inside the battery cause the silicon to expand dangerously. A research team has created a binding material that will keep a high-capacity silicon anode from expanding.
Currently, the specific energy of a lithium-ion battery is 100–265 Wh/kg (0.360–0.954 MJ/kg). Our Buzz has a 80 kWh battery providing a theoretical 400 km of range. Using the above data, the battery mass should vary from 800 kg to 302 kg. Personally, I see little need for this range to increase by a factor of 10 to 4 000 km. Even the most enthusiastic of users would probably be content with a 2 000 km range. Normal mortals would probably willingly accept 1 000 km,
If the specific energy of a battery increases to 1 to 2.65 kWh/kg (3.6 – 9.54 MJ/kg), then the mass of a battery with a 1 000 km range is probably somewhere between 200 and about 75 kg. A Volkswagen Transporter T6 2.0 TDI has a fuel tank capacity of 80 liters, with fuel consumption per 7.5 liters (combined) per 100 km, or 75 litres for 1 000 km range. The density of diesel is about 0.85 kg/ litre, which means that 75 litres has a mass of almost 64 kg. This does not take into consideration the mass of the storage container. This means that the mass of an EV battery is approaching parity with the mass of diesel.
In 2021, Equinor, Aire Liquide and Eviny started Project Aurora, at Mongstad, Norway. Its goal was to construct a Norwegian liquid hydrogen manufacturing facility for maritime shipping. They estimated that manufacturing costs would likely be ca. US$9.30 per kg. That project was permanently abandoned in 2023-03, because it failed to attract customers. Liquid hydrogen would also be needed for aviation fuels. However, this price is three times the cost of Jet A fuel. Transportation of hydrogen is a major challenge. The US Department of Energy states that a single tanker of gasoline contains 14 times the energy as a tanker of hydrogen. Thus, for both maritime and aviation uses, it may be appropriate to produce H2 near the facilities where it is being used. This situation may also apply to vehicle H2 fueling stations.
It is useful to compare energy pathways. Here, two such pathways will be examined. The first looks at the use of electricity to produce liquid hydrogen, which is used to produce electricity to power, say, an aircraft or ship. Start with 10 MWh of electricty. Turning water into hydrogen is about 70% efficient. There is about 7 MWh of chemical energy in the resulting hydrogen. Compressing, storing, transporting and distribution hydrogen uses another 10%, resulting in 6.3 MWh of available energy. Liquifiction is about 66% efficient, resulting in4.2 MWh of energy. Boil off uses another 5%, leaving about 4 MWh of energy. Burning hydrogen in a jet engine is about 50% efficient at optimum altitude and speed, but is closer to 40% efficient gate to gate. Thus 10 MWh of green electricity provides 1.6 MWh to move an aircraft.
The pathway for a battery aircraft or ship from wind differs significantly. From wind farm to the grid or a battery, it’s about 90% efficient. That results in 9 MWh of energy being available. There is an addition 10% energy loss using electric motors on the aircraft or ship. These would have about 8 MWh of energy available. This is five times the energy available on the hydrogen pathway.
Despite Volkswagen being the automotive brand that I have bought most frequently, I am not a loyal customer. The VW Buzz we currently drive will most likely be our last vehicle purchase. I appreciate having the opportunity to drive a quiet EV, that avoids combustion, and was delivered as a carbon neutral vehicle. I find the comments made by Volkswagen Group CEO Oliver Blume irritating, but not nearly as irritating as some of those made by Tesla CEO Elon Musk.
The final word on this subject will be given to Frank Welsch, Member of the Board of Management of the Volkswagen Passenger Cars brand with responsibility for Technical Development:
"Science is largely in agreement on this issue, as several recent studies have shown. The Federal Ministry for the Environment, for example, assumes that hydrogen and synthetic fuels, so-called e-fuels, will remain more expensive than an electric drive, as more energy is required for their production.The Agora Verkehrswende (traffic transformation) initiative also points out that hydrogen and e-fuels do not offer ecologically sound alternatives without the use of 100 percent renewable energies, and that, given the current and foreseeable electricity mix, the e-car has by far the best energy balance. In the view of the Fraunhofer Institute, synthetic fuels and drive technologies such as hydrogen in combination with the fuel cell will indeed play a role – but not so much in the passenger car sector, but rather in long-distance and heavy-duty traffic, as well as in rail, air and sea transport. These segments will only be converted in later phases of the energy turnaround, i.e. beyond the year 2030, and closely linked to the expansion of renewable energies."
"In fact, hydrogen-based fuel cell technology has one crucial disadvantage: it is very inefficient – both in terms of efficiency and operating costs. This is also confirmed in detail by a Horváth & Partners study, comparing both types of drive for e-cars from the customer’s point of view."
The traffic lights in Akureyri feature red hearts for stop. Pedestrian tourists like this, and comment on them waiting for the lights to change. As with most second-largest cities they have to do something, preferably positive, to shift the focus away from the largest city and onto themselves. Akureyri had a population of 19 219 in 2021, occupying 138 km2.
The Aviation Museum of Iceland is located in Akureyri. A Wikipedia article provides insights into the museum. This weblog post provides some photos!
