Farewell

It's exam day (hope you remembered WJ's advice on how to prepare), our last day in class. Your final report blog posts# are due Friday.

Last words, for now:

WJ's last published essay was inspired by his odd correspondent *Benjamin Paul Blood, who was convinced that nitrous oxide and other "anaesthetic" substances provide a revelatory key to greater depths of reality. That essay concluded:

...Let my last word, then, speaking in the name of intellectual philosophy, be his word.–“There is no conclusion. What has concluded, that we might conclude in regard to it? There are no fortunes to be told, and there is no advice to be given.–Farewell!” --A Pluralistic Mystic

But of course there is advice to be given: Be not afraid, keep asking questions, pay attention, stay healthy, don't worry, be happy, enjoy the journey, don't be a stranger...

And consider taking Bioethics in the Spring, and Philosophy of Happiness in the Fall.

#Final report blogpost

OPEN YOUR EMAIL AUTHOR INVITATION, then look for the NEW POST tab in the upper right on our blogsite (do NOT create a new blog, post your final report on our site)... The topic should complement, clarify, and elaborate on some central aspect of your final presentation. Share and defend your own view(s), if you have any. Try to imagine what your best critic would say, and how you'd respond. Address one or more of your discussion questions.... Aim for a minimum of 1,000 words... Include relevant links (at least half a dozen or so) in lieu of footnotes/bibliography, video & textual embeds (a couple), and graphics (one or two): let me know if you need instruction on how to do it... When referencing texts we've read in the course, cite page #s and abbreviations (MacA, McK, GT, etc.)... Make sure your post has formatted correctly. If not, use the Clear Formatting command in the toolbar in the upper right, above, to fix it... You can continue to edit and revise until the final draft is due...

Hydrogen teleported for first time in human history: 20 tons anywhere in the world

by Sanusha S.   12/02/2024

There is decarbonization that the world seems to be racing toward; hydrogen is seen to be one of the players in the clean energy revolution. Storage and transport remain big challenges in hydrogen, but innovations such as Liquid Organic Hydrogen Carriers or LOHC are remolding the face of hydrogen, making it more affordable and efficient in distributing it. Recently, pioneering projects that prove the high-demand and transformative use of this technology in the UK and Scotland are occurring for global implications about greener tomorrow.

Green hydrogen transport utilizing oil infrastructure is a pioneering effort by Exolum

In a historic first, Exolum has created the world’s first commercial-size project that uses existing oil infrastructure to transport and store green hydrogen. It is based at the largest freight port in England, Immingham, and the project depends on organic hydrogen carriers, compounds that can store hydrogen in liquid form in a safe manner.

This explains the hydrogen presence and absorption as well as dissipation by the carriers through chemical reactions. They are thereby utilized in efficient storing and transport without extensive new infrastructure construction. With funding of £505,000 from the UK government, the project shows the huge potential LOHC technology holds.

With a test plan to move 20 tonnes of hydrogen through 1.5 kilometres of pipeline, this project presents a scalable model to meet increasing hydrogen requirements. By placing storage facilities in immediate proximity to demanding locations such as industrial hubs and ports, Exolum conceives an accelerated supply chain to push ahead the clean energy transition.

 A surprise solar boom reveals a fatal flaw in our climate change projections

Solar is surging, but so is humanity’s energy appetite. We need better models.

When the satellites zoomed in, you could see the panels gleaming from space. Pairing images taken miles above the Earth with Chinese customs records, BloombergNEF solar analyst Jenny Chase and her team discovered this year that the rooftops of homes and factories across Pakistan are blanketed with solar panels. Catching their own government by surprise, Pakistanis have been installing a massive amount of solar power.

In the process, Pakistan has gone from an inconsequential solar market to the sixth-largest in the world. The country of 242 million has a power grid with a peak capacity of 46 gigawatts — that’s less than 4 percent of the US power supply for a country with more than two-thirds as many people. In the last three years, Pakistanis have imported more than 25 gigawatts of solar panels from China. This disorganized, bottom-up boom has increased Pakistan’s power supply by 50 percent.

The solar surge is driven by high local electricity costs. At 16.6 cents per kilowatt-hour, Pakistan’s electricity rate for businesses is 37 percent higher than its neighbor India, and more than double the average rate in Asia. Agreements made in the 1990s have kept the state stuck in expensive contracts with independent power producers, and power plants burn lots of liquefied natural gas, which became costlier after Russia invaded Ukraine in 2022. That same year, Pakistan fell into a foreign exchange crisis as the country’s dollar reserves plunged, which made everything more expensive.

All of this opened an opportunity for businesses and better-off Pakistanis to begin importing solar panels from China, which can pay for themselves in as little as two years and free their users from the expensive, unreliable grid. The middle class has started to do the same. The state has come under pressure to raise rates for the conventional grid to satisfy its contracts with power producers — which the increasingly shrinking, poorer customer base struggles even more to afford. Consumers who have made the switch to solar panels, like the owner of a factory that makes soccer balls in Sialkot, told the Financial Times, “Allah has given us this gift to get out of this mess.”

But there’s a bigger story here, beyond one nation’s problems with its power grid. What’s happening in Pakistan is the latest sign that energy authorities are underestimating how much clean power the world demands — and that energy models can suffer from the same biases as their makers. Those failures in number-crunching are not merely abstract. Failing to grasp how much energy is wanted, and the things people in places like Pakistan might be willing to do to get it, leaves the world unprepared to build, fund, and plan for a cleaner future.

How to prepare for an exam
If you want really to do your best in an examination, fling away the book the day before, say to yourself, “I won’t waste another minute on this miserable thing, and I don’t care an iota whether I succeed or not.” Say this sincerely, and feel it; and go out and play, or go to bed and sleep, and I am sure the results next day will encourage you to use the method permanently. --William James, “Gospel of Relaxation
If you’ve been up all night cramming, in other words, good luck. You’ll need it. But if you’ve been diligent, have steeped yourself in the subject all semester long, and either went out to play or to an early bed the night before, your luck will be the residue of design. You’ll do fine. Relax. But don’t try too hard to relax. It is needless to say that that is not the way to do it. The way to do it, paradoxical as it may seem, is genuinely not to care whether you are doing it or not. Care later. On exam day just show up and do your best.

Oxford’s 2024 Word of the Year Is…

A slang term for supposed mental damage done by overconsumption of trivial online content triumphed over a shortlist that also included "lore," "demure" and "slop."

"...It's been quite a journey for "brain rot," which triumphed over a shortlist of contenders including "lore," "demure," "romantasy," "dynamic pricing" and "slop." According to Oxford, its earliest known appearance was in 1854, in "Walden," Henry David Thoreau's classic account of moving alone to a cabin in the woods.

"While England endeavors to cure the potato-rot," Thoreau lamented, "will not any endeavor to cure the brain-rot, which prevails so much more widely and fatally?"

The answer, apparently, is no. These days, according to Oxford, it's often invoked by young people on social media to describe the "supposed deterioration of a person's mental or intellectual state," particularly stemming from overconsumption of trivial online content..."

Better times

Moving beyond the end…

"No wonder there is no lack of prophets who prophesy the early eclipse of our civilization. I am not one of these pessimists; I believe that better times are coming."
