2022 in Review

First, my heart goes out to anyone who suffered hardship or lost a loved one in 2022. People still died from Covid-19 of course, not to mention other diseases, violence, and accidents. People are living, dying, and suffering horribly in war zones from Ukraine to the Middle East to Myanmar. Having said all that, for those of us living relatively sheltered lives in relatively sheltered locations like the United States, 2022 does not seem like it will rank among the best or worst of years in history.

Highlights of the Year’s Posts

These are the posts I picked each month as most frightening and/or depressing, most hopeful, and most interesting.

Most frightening and/or depressing stories:

  • JANUARY: A collapse of the Game of Thrones ice wall holding back the Thwaites glacier in Antarctica could raise average sea levels around the world by one foot, or maybe 10 feet “if it draws the surrounding glaciers with it”. The good news is that no army of zombies would pour out.
  • FEBRUARY: Philadelphia police are making an arrest in less than 40% of murders in our city, not to mention other violent crimes. Convictions of those arrested are also down. Some of this could be Covid-era dysfunction. But there is a word for this: lawlessness.
  • MARCH: What causes violence? It’s the (prohibition and war on) drugs, stupid. Or at least, partly/mostly, the drugs.
  • APRIL:  The use of small nuclear weapons is becoming more thinkable. Just a reminder that nuclear war is truly insane. Assuming we manage to avoid nuclear war, food insecurity might be our biggest near- to medium-term issue. One lesson of World War II is worries about food security played a role in the diseased minds of both Hitler and Stalin. And food prices right now are experiencing a “giant leap” unprecedented over the last couple decades. Food security, natural disasters, sea level rise, migration, and geopolitical stability all can form ugly feedback loops. And no, I couldn’t limit myself to just one depressing story this month!
  • MAY: The lab leak hypothesis is back, baby! Whether Covid-19 was or was not a lab accident, the technology for accidental or intentional release of engineered plagues has clearly arrived. And also, the world is waking up to a serious food crisis.
  • JUNE: Mass shootings are often motivated by suicidally depressed people who decide to take others with them to the grave.
  • JULY:  One way global warming is suppressing crop yields is by damaging pollen.
  • AUGUST: The fossil fuel industry intentionally used immoral, evil propaganda techniques for decades to cast doubt on climate science and make short-term profits, probably dooming us, our children, and our children’s children. Also, and because that is apparently not enough, nuclear proliferation.
  • SEPTEMBER: If humans are subject to the same natural laws as all other species on Earth, we are doomed to certain extinction by our limited genetic variety, declining fertility, and overexploitation of our habitat. So, how different are we? I can spin up a hopeful story where are evolving and overcoming our limitations through intelligence and technology, but time will tell if this is right or wrong.
  • OCTOBER: Hurricanes are hitting us (i.e., the United States: New Orleans and Puerto Rico being the examples) and we are not quite recovering back to the trend we were on before the hurricane. This seems to be happening elsewhere too, like the Philippines. This is how a system can decline and eventually collapse – it appears stable in the face of internal stressors until it is faced with an external shock, and then it doesn’t bounce back quite all the way, and each time this happens it bounces back a bit less.
  • NOVEMBER:  Asteroids could be used as a weapon.
  • DECEMBER: The U.S. legalized political corruption problem is getting worse, not better. This was one of Project Censored’s most censored stories of 2022.

Most hopeful stories:

  • JANUARY: LED lighting has gotten so efficient that it is a tossup on energy efficiency with daylight coming through a window, because no window is perfectly sealed. Windows still certainly have the psychological advantage.
  • FEBRUARY: “Green ammonia” offers some help on the energy and environmental front.
  • MARCH: There are meaningful things individuals can do to slow climate change, even as governments and industries do too little too late. For example, eat plants, limit driving and flying, and just replace consumer goods as they wear out. I’m mostly on board except that I think we need peace and stability for the long term survival of both our civilization and planetary ecosystem, and we are going to need to travel and get to know one another to give that a chance.
  • APRIL: While we are experiencing a disturbing homicide wave in U.S. cities, violent and overall crime are not necessarily at historical highs and are more or less flat. And yes, this was the most uplifting story I could come up with this month. Brave politicians could use the Ukraine emergency to talk about arms control, but if anybody is talking about that I am missing it.
  • MAY: I came up with (but I am sure I didn’t think of it first) the idea of a 21st century bill of rights. This seems to me like a political big idea somebody could run with. I’ll expand on it at some point, but quick ideas would be to clarify that the right to completely free political speech applies to human beings only and put some bounds on what it means for corporations and other legal entities, and update the 18th century idea of “unlawful search and seizure” to address the privacy/security tradeoffs of our modern world. And there’s that weird “right to bear arms” thing. Instead of arguing about what those words meant in the 18th century, we could figure out what we want them to mean now and then say it clearly. For example, we might decide that people have a right to be free of violence and protected from violence, in return for giving up any right to perpetrate violence. We could figure out if we think people have a right to a minimum standard of living, or housing, or health care, or education. And maybe clean up the voting mess?
  • JUNE: For us 80s children, Top Gun has not lost that loving feeling.
  • JULY: Kernza is a perennial grain with some promise, although yields would have to increase a lot for it to be a viable alternative to annual grains like wheat, corn and rice.
  • AUGUST: “Effective altruism” may give us some new metrics to benchmark the performance of non-profit organizations and give us some insights on dealing with existential risks (like the ones I mention above).
  • SEPTEMBER: Metformin, a diabetes drug, might be able to preemptively treat a variety of diseases colloquially referred to as “old age”.
  • OCTOBER: Gorbachev believed in the international order and in 1992 proposed a recipe for fixing it: elimination of nuclear and chemical weapons [we might want to add biological weapons today], elimination of the international arms trade, peaceful sharing and oversight of civilian nuclear technology, strong intervention in regional conflicts [he seemed to envision troops under Security Council control], promotion of food security, human rights, population control [seems a bit quaint, but maybe we would replace this with a broader concept of ecological footprint reduction today], economic assistance to poorer countries, and expansion of the Security Council to include at least India, Italy, Indonesia, Canada, Poland, Brazil, Mexico, and Egypt [maybe this list would be a bit different today but would almost certainly include Germany, Japan, Brazil, India, and Indonesia].
  • NOVEMBER: A review of Limits to Growth suggests our civilization may be on a path to stagnation rather than collapse. Or, we may be on the cusp of a fantastic science ficition future of abundance brought to us by solar energy, asteroid mining (there are those asteroids again!), and biotechnology.
  • DECEMBER: Space-based solar. This just might be the killer energy app, the last energy tech we need to come up with for awhile. Imagine what we could do with abundant, cheap, clean energy – reverse global warming, purify/desalinate as much water as we need, grow lots of food under lights in cities, power homes/businesses/factories with little or no pollution, get around in low-pollution cars/buses/trains, electrolyze as much hydrogen from water as we need for fuel cells to power aircraft and even spacecraft. Solve all these problems and we would eventually come up against other limits, of course, but this would be an enormous step forward. And space-based solar seems like much less of a fantasy than nuclear fusion or even widespread scaling up of new-generation fission designs.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both:

Brilliant Synthesis

Technology

The last couple years, I led off with other things and came around to a technology roundup towards the end. This year, I’ll just shake things up (yes, I’m wild and crazy like that) and lead off with technology developments during the year.

Solar energy has been a long time coming, but 2022 was a year when it really started to be at the forefront of the energy conversation and hard for the skeptics to ignore. We keep hearing that it is now the cheapest form of energy to build and put into operation. That means it is now limited by the materials needed to produce the panels, by the space needed to deploy the panels, and by the transmission and temporary storage infrastructure. Building rooftops take up a lot of space and are mostly not used for other things, so this seems like an obvious place to put the panels. The oceans of pavement we use to operate and park vehicles make up another somewhat obvious place – we can toughen the panels and drive on them, or we can put cheap roofs over the pavement and cover them with panels. Materials can be an issue because many of them are mined and sold by unsavory characters and governments, and there is clearly an environmental impact. But remember that we are trading this off against today’s coal, oil, and natural gas industry, not against some socially and ecologically blameless party. This industry intentionally lied to the public for decades and in the process did immeasurable damage to a planetary biophysical system.

Metals and minerals are also just limited. But even in hard-nosed economic terms, if solar panels are the lowest-cost option as we are hearing, they are holding their own with the costs of extracting, transporting, and burning fossil fuels. We could tax social and environmental impacts at international borders if we had the courage to do so, but even without that it is hard to imagine a system more damaging and irresponsible than the one we have been dealing with for the past century or so.

People will also say we haven’t kept the distribution infrastructure up to date, and this is true. In the United States at least, we don’t keep public infrastructure in a state of good repair. But we do create infrastructure when big business demands it, and they will demand an electric grid that can support their products when it comes to electric vehicles, devices and facilities. There may be a period of pain between when big business demands it and when the U.S. government provides it, and other countries will almost certainly outdistance us.

Longer term, as Fully Automated Luxury Communism tells it, space for solar panels will not be a problem because we will put them in, well, space. And this is not a far-future fantasy. The technology to gather the energy in space and beam it to the Earth pretty much exists now and governments and companies are seriously working on practical implementation. They swear it is safe, and even if it is not totally risk-free remember again all the death, pollution, and permanent planetary destruction the fossil fuel sociopaths have wrought.

Now, what about nuclear power? If we had really focused on it decades ago, we might not be in the climate change mess we find ourselves in now. It could still be a solution to the climate change mess in the future. But given how long it takes to bring new nuclear technology online at a large scale, and how fast solar energy appears to be scaling up and how reliable it appears to be, is it time to stop working on nuclear? I’m talking about known fission technology here. As for fusion, given that it is “always 20 years away” (no matter the year we are actually in), is it time to stop working on it and just throw all our research efforts at solar?

And materials will not be a problem either because we will produce them from asteroids and bring them to Earth, ending material shortages forever. I say, good but better to just use them to build things in space because we are running out of capacity to absorb the byproducts of the materials we already have down here. Just digging things up that were already in the ground and pumping them into the atmosphere and oceans has caused enough trouble.

By the way, once we are in space and messing around with asteroids, government and private actors will be able to divert their trajectories. It is easy to imagine scenarios where this is a great thing that actually saves all life on the planet. It is also easy to imagine scenarios where industrial accidents or intentional government actions threaten life on the planet. An international treaty and some oversight of this seems like a good idea as the messing-with-asteroids industry really starts to get going.

I don’t have my pet mini-mammoth yet, but biotechnology is continuing to gain steam. The idea of treating aging as a disease to be cured seems almost too obvious, but it seems to remove some bureaucratic obstacles that have been holding science and medicine back. Covid-19 was probably, maybe, perhaps not a lab leak. But it could have been, because the technology to make something like it, or much worse, exists in labs right now. It could be made if it has not already, and it could be leaked accidentally or intentionally, if it has not been already. And like nuclear technology, it will proliferate. Compared to nuclear technology, I think it will proliferate much faster and be much easier to hide. I have trouble envisioning any solution to this that does not involve heavy-handed surveillance.

On the positive side, biotechnology may be able to feed us when there are a lot more of us. With cellular agriculture, we can theoretically make meat or just about any kind of plant or animal tissue, and then we can eat it. We may finally be on the verge of modifying plants so they can make more efficient use of the sun’s energy, which is both exciting and scary. With a combination of abundant cheap electricity (from solar energy), abundant cheap materials, and highly efficient lighting though, we might be able to grow all the food we need in high rises without needing frankenplants.

And finally, the idea of controlling the weather with windmills is pretty fascinating. If we figure this one out, we might be able to end damage from floods, droughts, and hurricanes. But obvious Bond villain Elon Musk will also be able to use this to hold the world hostage for ONE HUNDRED TRILLION DOLLARS. That doesn’t really matter though because he is probably already planning to crash an asteroid into us anyway.

Propaganda, Social Media, and Truth

Social media is being blamed for a lot of our social ills at the moment. When we hear “social media” discussed, it seems to mean first and foremost interactive sites like Facebook, Twitter, Instagram, etc. where anyone can post a short snippet of any information they want and make it available to anybody else on the platform. Youtube also seems to fit this mold to some extent, although Youtube is a mix of personal and professionally-produced content. Then, underlying all this are Google search and other algorithms or “search” engines which are searching both for content to show individuals and individuals to show content. There are bloggers using WordPress and a million other tools and sites trying to get their content out, usually not all that widely if my personal experience is any indication (to the 5 or 6 people worldwide who read this blog regularly?) Then there is the huge ecosystem of Amazon and all the other sites trying to sell us stuff. Then there is professional journalistic media and traditional publishing companies trying to have their say (and sell us stuff), and finally there is some sense of the broader internet underlying all this.

Beyond trying to sell us stuff, corporations and non-profit entities are trying to manipulate all these communication channels to get their messages into our heads. This is propaganda, with the main goal being to sell us stuff and a secondary goal being to create awareness and positive images of their brands so they can keep selling us stuff. Also so people won’t complain to politicians about whatever the corporations are doing and risk those politicians meddling in the system in ways that are averse to corporate profits. At the same time, these companies and special interest groups are paying off the politicians to support their interests behind the scenes. This works out well for them (the corporations, special interests and politicians).

Finally we have the U.S. government and governments around the world trying to influence public opinion, occasionally by providing accurate information, sometimes outright lies, and often something in between.

All this is competing for our “attention”. Personally, I strongly prefer having more information to less, and I do not want to see regulation aimed at reducing the amount of information available to me. I believe, perhaps naively, that I have some ability to distinguish truth from falsehood, fact from opinion, and objective/honest communication from dishonest attempts to influence me. Regulation to protect children might be an exception to this – if social media sites are facilitating bullying and leading to mental health problems and even suicides, that is worth dealing with.

“Great Power Competition”, the “International Order”, and the United Nations

A major world leader of our time died in 2022. Okay, two world leaders if you really want to count Queen Victoria, but I am talking about Mikhail Gorbachev. To me, he represents a moment when optimism and visionary leadership had a chance to flower to the benefit of our civilization. He had a vision of long-term peace and stability, with powerful nation-states ceding some of their power to some form of world government. The basic vision was that no nation-state, no matter how powerful, would be able to succeed through violent means if it was opposed by all other nation-states acting together. With the threat of catastrophic war mostly behind us, humanity could have focused on solving all the other thorny problems, from food to energy to pollution to inequality. This was a beautiful vision, but unfortunately its moment passed us by, and we are back to the old cynical idea of coalitions of “great powers” arrayed against each other.

With the threat of catastrophic violence hanging over us, we are not focused on solving those other problems. The United Nations was supposed to at least be the seed of that new order that would usher in long-term peace and prosperity for our species. To be sure, the United Nations has accomplished a lot when it comes to human rights, science, agriculture, refugees, and other areas. It has also been a place where all the not-so-great powers of the world can band together and make their voices somewhat heard. But the Security Council was supposed to be the One Ring to Rule Them All and make “great power competition” obsolete. This has failed utterly, with the Security Council considered all but irrelevant at this point. Not only is “great power competition” ascendant, we seem to be proud of ourselves for bringing it back. If there is a devil, he must truly love “great power competition”.

With the threat of catastrophic violence hanging over us, we have failed utterly to solve other existential problems such as food security, global warming, sea level rise, ever-growing concentration of wealth, and the specter of a Captain Trips extinction plague whether of natural or manmade origin.

Resilience. Despite taking a gut punch, at the end of 2022 it feels as though our planetary civilization weathered the storm of Covid-19 and has more or less rebounded to something like the trend it would have been on. This is the textbook definition of resilience, and something to feel good about. If we get some time in between gut punches, we at least have an opportunity to work on our other problems while also preparing for the next gut punch. If we don’t make progress, maybe we can at least reach a state of stagnation rather than a self-actuated collapse. Can a civilization be resilient and stagnant at the same time? Maybe this is where we find ourselves, at least in the near term.

Happy 2023!

January 2022 in Review

Most frightening and/or depressing story: A collapse of the Game of Thrones ice wall holding back the Thwaites glacier in Antarctica could raise average sea levels around the world by one foot, or maybe 10 feet “if it draw the surrounding glaciers with it”. The good news is that no army of zombies would pour out.

Most hopeful story: LED lighting has gotten so efficient that it is a tossup on energy efficiency with daylight coming through a window, because no window is perfectly sealed. Windows still certainly have the psychological advantage.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: “Big history” is an Australian program that attempts to unify everything from the Big Bang through our current era of intelligent life.

LED lighting vs. windows

Treehugger asks if LED lighting is more efficient than daylight. It seems like a dumb question at first because isn’t daylight free? But the problem inside buildings is that windows allow heat to come and go in addition to light, and LEDs have gotten so efficient that it is not an easy question to answer whether bricking up a window and replacing the light with LEDs would be more or less energy efficient. They conclude that windows should be designed with human comfort and happiness in mind.

what’s new with “passive house”?

Well, by combining an “airtight envelope” with solar arrays, a passive house certified nursing home in Spain can actually generate more energy than it uses.

The new nursing home extension is topped with an 18 kW photovoltaic array along with 20 solar thermal panels and rooftop seating. When combined with the building’s airtight envelope, which was engineered to follow passive solar strategies, the renewable energy systems are capable of producing surplus energy, which is diverted to the old building. The Passivhaus-certified extension also includes triple glazed openings, radiant floors, rainwater harvesting and mechanical ventilation equipped with heat recovery. 

Inhabitat

So the technology exists to build like this, so why don’t we do it everywhere? Well, part of it is ignorance and resistance to adapting ideas from elsewhere to one’s own locale. A lot of it is legitimate concerns about cost. But new materials and skills can be expensive because they are in short supply locally. So, bring in a technology like this, set up local factories and training programs to build capacity, encourage entrepreneurs, provide successful examples and incentives and possibly regulations, and you can bring cost down. When the people doing it forget the old way of doing things, assume the new way is the way it has always been and the only way it can be, and are resistant to the next new idea that comes along, you have made progress.

can we use energy again and again?

I’ve had a few colleagues mention this story on making jet fuel out of industrial waste.

“This fuel takes waste, carbon-rich gases from industrial factories, and gives them a second life so that new fossil fuels don’t have to be taken out of the ground,” Virgin Atlantic founder Richard Branson told The Guardian. He added that this flight was a big step toward making the new fuel blend part of the mainstream…

Jennifer Holmgren, LanzaTech’s chief executive, said that her company has shown that recycling waste carbon emissions into jet fuel is possible. She added that we should look at waste carbon as an opportunity, because it can be reused again and again.

I did a little more research and what is happening here is that “waste” from the factories contains hydrocarbons that can be distilled into ethanol. This is a good idea, clearly. I just want to point out that there are only two possibilities here: either these people have come up with a perpetual motion machine allowing the same fuel to be “reused again and again”, or else the second law of thermodynamics is still in effect. I would tend to bet on the latter. Snark aside, what it must mean is that the energy source was always there, but technology has improved to the point where it can now be recovered economically. If that’s the case though, I wonder why the factories involved wouldn’t want to make use of the technology to improve their own efficiency while reducing their waste. If that is now an economical thing to do, it seems like that might be more efficient to do onsite rather than capture the waste somehow, concentrate it, transport it, process it, then transport it again. Unless there is some significant economy of scale involved that makes it all work. Anyhow, you can’t really be against energy efficiency or reduced pollution and greenhouse gas emissions, so bravo everyone.

passive house

This article describes how an old home was retrofit into an extraordinarily energy efficient “passive house“.

I’m guessing the owners are not poverty-stricken. Then again, there must be some payback period and I wonder if it is measured in years or decades. If it pays back reasonably, there should be some kind of financial arrangement that would allow ordinary people to do this.

fan buying guide

Let’s face it, cheap fans are annoying. Normally you get a new fan when you a desperate for one – either an old one broke, your air conditioning is on the fritz, or you have company coming and need to cover an additional room. You stop by your local drug store, hardware store, or big box monstrosity and pick up whatever they happen to have. No matter how cheap, it almost always does the job of making air move. But your cheap new fan is loud, rattly, and just all-around annoying. There are some better models out there, and if you have just a few days to plan ahead you can order one of them.

Sense what is using electricity in your home

This is pretty cool – a device that can learn the patterns and measure the electricity use of individual appliances in your home, all just from being plugged into your fuse box.

The company says it can accurately disaggregate 80 percent of home energy use; it can do things like detect a microwave oven through its very specific startup and operating power “signature,” or sense a washing machine thanks in part to subtly increasing demand on the motor as the drum fills with water. As it identifies garage door openers, toasters, microwave ovens, washing machines, heaters, and refrigerators, it displays them on an app as a newsfeed and a series of labeled bubbles.

Sense—founded by speech-recognition veterans whose technology ended up in Samsung’s S-Voice and Apple’s Siri—consists of a box about the size of an eyeglasses case installed inside or next to an electrical service panel. Two inductive current sensors sense current, and two cables power the box and sense voltage. The box does some onboard processing, and then uses Wi-Fi to send data to the cloud for further analysis and aggregation with data from other users to improve its accuracy.

passive house

Here is a long article with some details on the passive house standard, which promises order of magnitude energy use reductions in buildings. It was invented in the United States, forgotten/ignored in the United States, adopted in Europe, and now is finally filtering back from Europe into the United States.

The passive house standard requires a tightly sealed and heavily insulated building envelope to ensure optimum energy efficiency. The minimum airtightness level allowed is 0.6 air changes per hour under 50 pascals of pressure. To ensure that a house is in compliance with this limit and that there are no leaks, the building’s designers conduct an on-site blower door test. “The biggest challenge is the sealing,” says Priputen, adding, “If you have a weak spot you have to make all of the other areas stronger in terms of insulation and air sealing.”

The other main pillar of passive house construction is a compact air and heat exchange system that conserves energy by transferring heat and/or moisture between incoming and outgoing streams of air. Designers specify one of two systems, depending on the site’s climate: heat recovery ventilators (HRVs), which transfer only heat, or energy recovery ventilators (ERVs), which transfer both heat and moisture.
