According to AI: Netherlands has introduced the “Wind Tree,” a vertical structure covered with hundreds of small, leaf-shaped turbines that generate electricity from even minimal wind. Unlike conventional wind turbines, these trees blend seamlessly into urban or park landscapes while producing renewable energy.

Every few months since I got into the renewable energy business 16 years ago, I’ve seen artists’ rendering of this idea.  I agree that it’s attractive to the eye and to the imagination. I also think it would make a fabulous science project.

Yet it has no practical value.  Bazillions of tiny moving parts that generate incredibly small electric currents can’t possibly make sense in the real world.

Regarding Trump’s competence, I suppose that if you want the United States to look like Turkey, Hungary, Russia, China, or any of the other totalitarian states, you have to admit that Trump is super-competent.  His will is unaffected by any group of people in government, e.g., congress and the Supreme Court.  Most important, it’s unaffected by our nation’s Constitution.

Moreover, as shown below, Trump is a master at using his position as U.S. president to enrich himself.

Some people are going to be impressed by that.

There’s a story behind the piece below, Chopin’s “Heroic” Polonaise, performed by Vladimir Horowitz, the pianist most people deem Chopin’s pre-eminent interpreter.

Frederic Chopin was born in 1810 near Warsaw, Poland, and was known as a child prodigy as a pianist and composer when he was six years old.

By the time he was nine he had studied under every piano instructor in Warsaw.  It was common for these teachers to talk about young Frederic, some saying, “We need to break him of some of his terrible habits.”  Fortunately, one said, “Here’s an idea.  Since he plays far better than any of us, why don’t we just leave him alone?”

Russia had long ruled Poland, but in the 1820s, Russian rule grew more arbitrary, and secret societies were formed by Polish intellectuals in several cities to plot an insurrection. In November 1830, Polish troops in Warsaw rose in revolt.

Chopin had moved to Paris shortly after his 22nd birthday in 1832, where he would spend the rest of his life composing, teaching, and concertizing, but his love for his native land remained fierce.

But what could he do? Chopin was small and sickly, barely five feet tall, perhaps 90 pounds in weight. He certainly couldn’t be a physical part of an uprising, so he decided to inspire his native Poles with his compositions.

There are a few good examples of his works along these lines, but the Heroic polonaise stands by itself. When I hear it, especially performed by one of the greats, a single word comes to my mind: bravery.

Enjoy, and don’t be embarrassed if you have goosebumps on your arms and tears in your eyes.

 

Some of us are looking for a single, simple statement to encapsulate what is going so wrong in America today, and perhaps it relates to what Aristotle says at left here.

Even the MAGA folks think that what they’re doing is “right.”  By this I mean white supremacy, mass deportation of immigrants (with or without due process), the rejection of science, and so forth.

Many of us have seen the illustration here, where a solar PV array is put into a geosynchronous orbit, and sends microwave energy to a collector on earth.

There is nothing theoretically impossible about the idea, and one good thing about it is that it increases the capacity factor (the ratio of actual electrical energy a power plant produces over a period to the energy it could have produced if it operated at its maximum continuous power output during that same period) from about 0.2 to 1.0, because the sun never “sets.”

The problem is the enormous cost of building, launching, and maintaining the entire apparatus. The price of electricity under such a scenario would cost thousands of times what it is today.

Trust me, Japan is not even considering this concept.

The other day, Defense Secretary Pete Hegseth made a speech before the nation’s highest-ranking generals and admirals, which was regarded at best as a waste of time, at worst as a slap across the face to the men and women who have risen, over many decades, to the very top command posts in our armed forces.

The idea that these people got where they are by refusing to hurt other people’s feeling is a sick joke. I’m sure many people in the audience were thinking, “Given five minutes alone with you, I wouldn’t hurt your feelings, but I would break a few of your bones.”

This is not sustainable.

Here’s a clever meme about what, exactly, is antifa.  Those (like me) who find it funny do so because “antifa” means nothing more than “anti-fascist,” i.e. opposed to fascism. I may be a Philadephia Phillies fan, but that hardly means that I’m a member of an established group of people with likeminded beliefs, that is prone to violence.

Examples of antifa include my father (and 16.4 million other U.S. servicemen) who fought the Nazis in the Second World War, and those of us today who oppose Donald Trump’s grossly illegal and anti-democratic government practices.

Liz Cheney is one of the very few Republicans of integrity in the U.S. Congress today.

When we read her words here, we’re impressed, but we wonder, when Trump is gone, if any aspect of the concept of honor will remain.

Whenever I run across nonsense like this, I’m reminded of the two school administrators I met recently, and this subject arose.

I asked them, 1) how often do elementary schoolers (age 5 – 7) want to know about human sexuality? 2) How many teachers want to raise this subject with the little kids? They both agreed that the answer is exactly zero, never.

It’s just far-right extremist crap, designed to infuriate idiots.

Our civilization has lost one of its giants with the passing of Dr. Jane Goodall.

One of the great primatologists with her exhaustive study of chimpanzees, she became even better known for her conservatorship of the natural world.

About her decision to become a vegan she said, “I remember looking down on a plate full of pork chops and all I could see was fear, pain, and death.”

RIP.
