Today is the shortest day of the year, with the sun at its lowest angle at noon. Using only photovoltaic solar power, today I get the least potential for energy. It’s less cloudy than usual, so I’ll get some power, but a tall building a block south of mine blocks the sun for most of the morning. Actually, low buildings do too. Here’s a schematic illustration: Here’s a more detailed[…] Keep reading →

I can’t believe how little value people place on trees. Each year I ask myself if I want to bother taking all those pictures of trees people throw away. Am I going to change culture this way? I doubt it. Then again, I’m not hurting anyone and I’m going to post daily anyway. Then I see another Christmas Pagan tree being thrown out well before Christmas. This one appears denuded.[…] Keep reading →

Readers who have followed my blog over a year know that for the past few years I’ve taken pictures of the trees people throw out on the street. Since history shows that the tradition that Americans associate with Christmas came from paganism, and I’m concerned people who complain about “wars” on Christmas or Christians, I call them Christmas Pagan trees. That way if someone quotes me about how we can[…] Keep reading →

The building with the clock tower in the picture below is my local public library. The iron fence behind the guy in the white hat encloses a park behind the library. It had two crab apple trees in it. As far as I could tell, nobody else knew it produced crab apples. The branches were higher than you could reach or even see the crab apples since they were the[…] Keep reading →

This photograph shows a guy employed by a local “business improvement district” to pick up litter, the “BID” on the gray trash bag and his coat/uniform show. How do we reach this level of failure? In principle we shouldn’t litter. For that matter, with all the talk about circular economies and reaching “net zero,” shouldn’t we not produce goods that could become litter? Doesn’t New York City have a sanitation[…] Keep reading →

I see these plots a fair amount from people on the right. They come from Bjorn Lomborg. They’re a straw man and a distraction. Global warming is a problem, but it’s one of many. As I’ve written, I recommend Only specify fixing climate and carbon if you want to wreck everything else (forests, biodiversity, rivers, etc) because that happens when you do. There are other places where our behavior mediated[…] Keep reading →

I just found this opinion piece in the New York Times from 2023: The World’s Population May Peak in Your Lifetime. What Happens Next? It starts: The global human population has been climbing for the past two centuries. But what is normal for all of us alive today — growing up while the world is growing rapidly — may be a blip in human history. Children born today will very[…] Keep reading →

The winter solstice is in one month. During the summer if I need to charge, I can go to the roof any time from around 8am to 8pm, weather permitting. This time of year, the sun only rises high enough to charge from about 9am to maybe 3pm. It’s cold. It’s windier so I can’t leave the panels alone because if the wind catches them, they blow like a sail.[…] Keep reading →

When did a 5,000-year-old practice to attain liberation and promote physical and emotional well-being come to hurt people for centuries, even millennia? Here’s a definition of yoga I found online: Yoga : a Hindu theistic philosophy teaching the suppression of all activity of body, mind, and will in order that the self may realize its distinction from them and attain liberation : a system of physical postures, breathing techniques, and[…] Keep reading →
