This is the Huntley Coal Plant started in 1916. Units were added until it reached 780 MW in 1963 & that level was maintained for 35 years. Plant output declined from 1999 to 2017 when it was retired after a century of operation. This view from the house where I was born. Huntley was big, ugly & surrounded by coal piles. However, unlike wind & solar farms it provided reliable base load power for decades. This ugly old coal provided useful power for a century despite the fact that it operated less than 12 miles from the huge carbon-free Robert Moses Niagara Falls Hydroelectric plant.

Conventional thinking treats wind and solar as permanent infrastructure. They aren't. These are a form of short life-cycle, industrial gadgetry with roughly 15-to-25-year lifespans. They are all in various stages of permanent decay and replacement - hydrocarbon and nuclear plants last generations. We see this in the mounting graveyards of unsalvageable wreckage. Yes, much of it can be recycled in theory. But in reality, the economic and energy costs usually outweigh the benefits. They are now decomposing faster than we can replace them and this is the Treadmill Effect. If a nation installs 5 GW of wind power every year, by Year 20, they aren't expanding the grid anymore. They are being forced to build 5 GW just to replace the rusted, fatigued and degraded turbines built in Year 1. Growth flatlines, swallowed up in pure maintenance. Look at the scale of this dilemma: despite millions of massive turbines and solar arrays deployed over 40 years, hydrocarbon fuels still dominate at roughly 81% of global primary energy. Solar and wind deliver only a tiny fraction of total primary energy. We've reached the limit. Almost every turbine and panel built over the last two decades is now in the late stages of decomposition. We're struggling just to keep up; and soon we will fall behind. The mines will become hollowed-out and these 'green' rust collectors will fall apart where they stand. To feed this replacement treadmill will need an astronomical volume of minerals: like copper, nickel, cobalt and rare earths. But we have already devoured the high-grade ores. A century ago, copper ore was 5% metal. Today, major mines are crushing ore that is less than 0.5% copper. To get the same tonne of metal, you must blast, haul and crush ten times more rock. This requires more massive, diesel-guzzling mining fleets and heavy industrial smelting. We are cannibalising dense, reliable fossil energy just to chase low-density, short-lived weather collectors. Here is the Einsteinian paradox. In physics, the closer an object gets to the speed of light, the more massive it becomes, requiring exponentially more energy to move it a fraction further. The energy transition is its own relativistic wall. The closer a grid gets to 100% renewable penetration, the greater its structural costs will become. You don't just need more panels; you need a parallel universe of over-building, synchronous condensers, and continent-spanning transmission lines just to handle the asynchronous volatility. We are hitting that Inversion Point. The fossil fuel energy required to mine the rare earths, manufacture the turbines and endlessly replace the dying infrastructure will eventually outpace the net energy the system delivers. You cannot reach the limit of light. Albert Einstein - the ultimate observer of universal limits - would smile at the irony. Net Zero is being driven by an ideological bureaucracy that reads financial blueprints but ignores the periodic table and the laws of thermodynamics. Entropy is universal. Nothing can bypass it. Imagery of rust, mechanical exhaustion and the accumulation of unmanaged composite materials.

Human nature. Humans evolved to live in small hunter-gatherer packs. To survive early, humans needed social cohesion within the pack but the ability to use violence & aggression against threats to the pack. We've learned to form larger packs but social cohesion isn't universal. Humans aren’t evolved to live like social insects as components in a large colonial superorganism. As much as the socialists & the UN may wish it, humans aren’t evolved to live as components in a global super colony.

The swarm of early unguided rockets with folding fins looked impressive but were very inaccurate. As the rockets exit the pod, they are buffeted by aerodynamic forces before the stabilizing fins completely deploy & are tipped off course. The film shows them beginning to scatter. When I worked for the Army, attack helicopters were still using the unguided 2.75-inch Hydra rockets, which had a similar accuracy problem. They were termed "area weapons," meaning the warheads scatter more or less randomly around the aim point. While the Hydras had good-sized warheads, their inaccuracies limited lethality. Putting a warhead on or in the target greatly increases lethality. I'm happy to see guided versions of the 2.75-inch rocket coming online. Sensors, computers, & batteries will displace warhead volume & mass, but increases accuracy should increase lethality.

Young Affluent White Liberal Women (AWFL) are whining because the males they used their political power to suppress aren't appealing life partners. Hypocritically, they still want a male protector/provider partner after calling men who want to play that role toxic. I got my first BS degree in 1972. That year 57% of 4-year undergraduate degrees were earned by men & 43% women. In 1980, gender equality, 50% earned by each. However, by 2024 42% where earned by men & 58% woman. So young AWFL your feminist politics made "your bed," enjoy sleeping in it alone.

This NPR article focuses on how we have "missing economically stable men” boiling it down to not enough going to college. But why is this happening? They never mention how, for decades, we’ve only given support, encouragement and resources to girls and women. We’ve told boys and men to “step aside.” They make it sound like it’s all the men’s fault without taking a good hard look at what society has down to hurt our boys and men and ensure they don’t succeed. If we can’t call out the true problem, we’ll never find real solutions.

Selling millions of metric tonnes of coal annually to China to power their ~1,200 coal plants (and growing) is fine. 18 coal fired plants in Australia is an emissions problem. Hit ♥️ if you think Australians are being scammed by net zero grifters

When I worked as DoD civilian physicist. We tried very hard to hire & promote women & minorities. Many leadership positions went unfilled because we couldn't meet race & gender quotas. The university talent pool had many foreign Asians students but few blacks or women. The NFL is sports meritocracy that ended up 58% black, 38% white/ multiracial & only 3% Asian/Pacific Islanders. Physicists are self-selected for intellectual arrogance & come from all races & ethnic backgrounds. Physics is also a meritocracy but intellectual, not athletic; different skill sets. If Professor Small believes Physics organizations can be "fair" only if they look like the NFL, he is delusional. (Has he ever met one of us Physics nerds?) I suggest Professor Small leave the bubble of the "African Studies" Department & visit the physics, engineering, or math departments of a university.

@SOrbit31914 Obama. Easily the worst. Bill "Bubba" Clinton was a woman chasing sleaze bag but was willing to move back to the center to win elections. Obama, while not philander like Clinton, was a thorough-going leftist radical not willing to compromise at all.

The Oaks are ready but the wooden warships they were grown for are decades out of date. This demonstrates the fallacy of long-term linear projections of current trends that "futurists" use. These projections are beloved of liberal women who live to restrict our lifestyles. Despite the failed prediction of "peak oil", the death of barriers reef, sea level rise & submergence of NY city they remain emotionally tied to the theories of catastrophe. The Danish Oaks aren't a catastrophe. They can be used for durable furniture if not warships.

В 1807 году Дания потерпела сокрушительное поражение в морском бою от Великобритании. Датский флот был практически уничтожен, и Дания начала программу посадки дубов для будущего кораблестроения. Эти дубы называли flådeege («флотские дубы»). Было высажено порядка 90 тыс деревьев. В 2008 году Министерство природопользования направило официальное письмо Министерству обороны, что дубы выросли до нужных размеров и можно строить корабли.

@ManifestHistory An accurate reading of military history shows little correlation between moral virtue & military talent. Several great military leaders, such as Nepolitan, Rommel, Robert Lee, Isoroku Yamamoto & Bedford Forrest served immoral causes. Basically, life is not fair.

If President Trump withdraws from the Persian Gulf without verifiably ending the Iranian nuclear program, then it will be a US defeat. The radical left will use the defeat to seize power in the US & destroy the country. The isolationist right is part of the problem. Their "no boots" on the ground rule seems to be keeping Trump from telling the Marines to take Kharg and the islands in the Strait of Hormuz. We should never go back to futile "nation-building" missions. But in any case, we don't have enough troops for a ground invasion. However, occupying the islands would go a long way to open the Strait & to destroy Iran's economy while allowing much of our Navy to withdraw.

@AntiWokeMemes Islam is regions not a race, get your terms right. I grew up in Buffalo in the 50s & 60s & often saw nun's in habits but I haven't seen one in decades. Unlike Muslim, Catholics never required all women to wear the habit. Muslims want to impose their idea of modesty on all women.

PM Starmer is pushing an extreme globalist socialist agenda by displacing the UK's resisting indigenous European population with new Muslim immigrants. Starmer is clinging to power as PM. He & his government could be dismissed by the Monarch but instead Charles III backs him.

While the Hs129 had several design similarities to the A-10 it might not be considered its ancestor. The chronically underpowered Hs129 was displaced by Ju87G "canon bird," an awkward modified dive bomber. The IL-2, like the A-10, was a purpose-built, armored, ground attack design. Unlike the Hs129, the IL2 Stormovik was built in large numbers & used successfully against tanks. The IL-2 differed from the A-10 in that it was single engine, 2 seat aircraft that used small shaped charge bombs rather than an autocannon to attack tanks. The Hs129, like the A-10 was a twin-engine, single-seat plane that used a 30mm autocannon to attack tanks. However, since Hs129 was considered a failed design I don't consider the ancestors of the very successful A-10.

Meet the WWII Tank Killer That Became the A-10’s Forgotten Grandfather Long before the Warthog, Germany built the Henschel Hs 129 a heavily armored tank hunter designed for low altitude ground attack during World War II. Armed with a massive 75 mm anti tank cannon and protected by a steel “armored bathtub” cockpit, the Hs 129 sacrificed speed for survivability and devastating firepower.
