From Democracy Now: In Tulsa, a white security guard faces charges of manslaughter for the fatal shooting of a Black man, Carlos Carson, in a motel parking lot earlier this month. New video emerged Friday showing Christopher Straight — a former sheriff’s sergeant — pepper-spraying, then shooting 36-year-old Carson in the head. Carlos Carson was a father of three.

I’d be very interested to know how one can commit manslaughter with a gun, let alone shooting the victim in the head. You put a bullet in another man’s brain and you didn’t intend to kill him? What precisely was your intention when you pulled the trigger?

My stock broker sent me his company’s quarterly report that, as usual, is so bland and noncommittal as to be very difficult to stay awake through.

I never put too much faith in this type of forecasting, and especially not now.  No one seems to be predicting this, but I don’t see why it’s so improbable that we’ll have a severe recession and possible depression as it becomes ever more clear that COVID-19 has: (more…)

As cities seek low-carbon alternatives, many regions are looking into microgrids. According to the US Department of Energy, a microgrid is a group of interconnected resources that act as a separate controllable energy source. There are three different types of microgrids. Remote, grid-connected and networked. The most common are remote and grid-connected. (more…)

I’m always impressed (he said sarcastically) by people in technology who provide numbers that are expressed in units that don’t exist, like KW/day. That’s like saying my driveway is 60 feet per second long.

I had a friend in college who would ask questions like: “Is it farther to New York or by car?” and “How long is a piece of string?” The difference: he was kidding.

Sir:

The United States has 4.2% of the world’s population and 26% of COVID-19 deaths. Precisely what kind of spin can anyone put on that?

If the news media tried to make that sound good, they’d have the same level of credibility that you have outside your cult: zero.

Here’s a piece that doesn’t come from mainstream news, but rather from the world’s most distinguished medical journal:  The Lancet recently published a scathing, unsigned editorial pleading with U.S. voters to choose a president that will “understand that public health should not be guided by partisan politics,” and slammed Trump for his “inconsistent and incoherent” response to the coronavirus pandemic.

While hydro energy is carbon-free (after the construction), there are numerous environmental drawbacks.

Here’s an extremely minor one.  The world’s largest dam, China’s $30 billion, 22.6 gigaWatt Three Gorges, when completely full, will retain 9.43 cubic miles of water, weighing 42 billion tons. That mass of water, 500+ feet above sea level adds to the Earth’s “moment of inertia,” which is the inertia of a rigid body against spinning on its axis. (more…)

A reader notes:  BS.  This will never happen.

Actually, this isn’t that hard for me to imagine. To think he’s going to walk away from every criminal acts he’s committed over the past 3.5 years, you have to believe that the entirety of the state and federal justice systems are going to overlook dozens of different types of glaring violations of criminal law.

Once he leaves office, he’s almost certain to be hit with indictments on any or all of several different charges: (more…)

In an effort to build taller wind turbines that take advantage of the superior conditions high above the Earth’s surface, GE has begun developing relationships with partners that will culminate in the 3D printing of the huge bases required to ensure stability of these mammoth structures.

But capitalizing on better wind conditions is only one advantage.  Another becomes obvious to anyone who’s ever seen turbine’s parts shipped out to the remote locations where wind farms are sited; the logistics are horrible.  These printers can be co-located, eliminating the need for transportation.

Exactly one half (50%) of Republicans surveyed recently answer yes to the question: “Do you think President Trump is a good role model for children?” That’s sickening, but it’s down from 72% in an identical poll taken in May of 2018.

It’s hard to know which of Trump’s virtues they deem most important to be passed along to the next generation.  Is it his unflagging honesty, marital fidelity, self-sacrifice for the people, humility, fact-based decision-making, devotion to education, environmental stewardship, reverence for the U.S. Constitution, showing compassion to the suffering, or perhaps respect for rule of law?
