It’s worse. Just heard some of the testimony and the idiot is talking about an all electric Navy by 2030.

Thar is so far beyond current technology as to be beyond fantasy. The current peak of battery tech resides in a Ford pickup and contains around 110 kW hours. This is approximately the equivalent of 140 HP hours or 14 HP x 10 hours or some equivalent multiple. The Ford pickups have proven worthless for towing any load more than a few miles.

The current US Destroyer, the Arliegh Burke class, is powered by 4 gas turbines with a combined out put of 78,000 kW, or about 105,000 HP. That’s just propulsion, in addition there are generators on board totaling 21,000kW for misc electric power. So we’re talking about right at 100,000 kW of power generation onboard.

If they get into wartime mode, I’d expect they would need the great bulk of that. A Ford PU battery would power that for around 3 seconds, 1000 Ford PU batteries would push it for an hour.

But a deep water war vessel has to be self reliant for weeks. Even just patrolling at cruise speed, the power requirements must be in the 20,000 kW range. Your hypothetical 1000 Ford batteries would power it for 5 hours then.

And you may think you’ve heard of what happens in a battery fire.

Lets say that battery tech has increased 50X, allowing an Arleigh Burke to do it’s normal 5100 mile cruise at 20 knots and you pull into some South American port on your last couple of kW and looking to recharge 4,400 megawatts hours. And that powered by windmills that aren’t working right now. Yeah, right.

Charging at sea? How’s that going to work? The replenishment boat is running on batteries too.

We are no longer a serious nation. We’ve collapsed into a silliness and stupidity forced on us by, what?

(Editorial Note:

This post is in reaction to this linked post: We’re Better Than That

that stated that determining whether America was still the “best” place to live based on available freedom was a worthwhile exercise.

Problem is, the ones who say that other places are worse are pretty much right. Singapore is wealthy but they’ll cane you for chewing gum. Australia, NZ, Canada and the UK are all serfs to their mega-parliament. Disarmed, cowed

In Scotland it is an arrestable offense if you walk too closely behind another at night. In England, carrying a Gerber or Leatherman multitool is fairly serious arrestable offense. In the UK you can be arrested, held without council, interrogated, have your kids dragged off to social services, then released without charge (in other words, political terrorism) for owning or distributing pamphlets supporting a legal political party, UKIP. And they’ll do it a couple times a month until you are sufficiently subdued.

Look at what Trudeau has been up to the past couple of years. Japan and South Korea are xenophobic. Mexico is now a failed narcostate. Argentina is normally ok but they have coups and other issues on a regular basis. The entire continent of Africa is screwed. Western Europe is woke as hell.

Eastern Europe is attractive but too close to Russia who will not be satisfied with Ukraine. The Caribbean is as rife with crime as when the pirates ran the place. Ecuador isn’t bad if you can handle the climate and altitude. Costa Rica is okay but its crime is rising. Most of the rest of South and Central America is second world.

Brazil is becoming quite crazy. Great beaches and attractive women, though, but I doubt Camera Girl is going to go for that. Israel is the only sane place in the Middle East but of course they are embattled. If I had to move I believe I’d choose either Argentina or Romania/Czech Republic despite their issues

Then again, you and me both have cherished family in the States. I would not want to remove myself from their proximity. My last act of love may be to die defending them if things go bat-crap here. If so, I will sing my death song and die like a warrior going home.

Guest Contributor – Glenn W – 18APR2023 – Subjectivity on the Right

ZMan, as a rule, is an excellent observer and commenter on the moral and social decline of the West. That being said, his over confident analysis of the psychology of woke is subjective and full of unsupported allegations. I’m not going to try and write a comprehensive critique but I do want to point a couple of things out that are worth considering.

I know James Lindsay and Paul Gottfried got into a dust-up but haven’t followed it closely. I don’t have, and won’t have, a Twitter account so I couldn’t follow the discussion. This statement by ZMan is, at best, a half truth:

“It needs to be said that Paul Gottfried’s dog probably knows more about this topic than Lindsay will ever know. Given Gottfried’s connection to Frankfurt School theorist Herbert Marcuse, he is as close as we get to an expert on the forerunners of this new ideology gripping the minds of the ruling class.”

First of all I’ve heard Gottfried say that his PhD is in European history. His studying under Marcuse as a PhD student gives him no special insight into what is happening now. He may have such insight but it isn’t because he studied under Marcuse 60 years ago.

Lindsay has spent a tremendous amount of time studying the “woke” primary source material and can legitimately be called a subject matter specialist. That does not mean he can’t make mistakes but ZMans blowing him off out of hand is just hand waving.

This ZMan statement made me chuckle:

“That said, there is a tendency of people on what we call the Right to engage in the same binary thinking we see with the people we call the Left. That means playing the old game of linguistic guilt by association.”

Let me get this straight: Paul Gottfried who studied under the hard core leftist Herbert Marcuse is a great guy but Harry Jaffa who studied under that “mediocrity” Leo Strauss is a bum. Gee, that seems pretty binary to me. Projection anyone?

The last thing I want to point out is ZMan claims special insight into the psychology of the “woke” ruling class. While he is a smart man he has no claim to special insight into the hive mind that is our “woke” overlords. His opinion isn’t worth any more than those dreaded civic nationalists.

AI medical imaging potential should not be stifled.

 

“Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.”

-Marie Curie (1867-1934)

 

The de facto position concerning new medical discoveries cannot be that it will inevitably be used for sinister purposes. This anti-science viewpoint stifles innovation and progress for humanity, thus stunting potential breakthroughs in medicine. Tools available to researchers and health professionals are just that, tools. The usage and application are dependent on who wields these instruments. It is not hard to imagine the first Neanderthals who discovered fire might have been dubious about its utilization, once one of them tried to touch it.

Recently it was found that Artificial Intelligence (AI) used to screen medical images can detect with near-perfect accuracy the patient’s racial ethnicity without prior knowledge from outside inputs. This ability for AI covered a broad series of image types; from CT scans to chest X-Rays, and persisted over all anatomical regions. This finding was replicated even from images that were cropped, corrupted, or not ideally clear. Even more surprising is that human experts trained to analyze these scans cannot determine the patient’s race, yet AI trained with deep learning developed this ability by itself.

The AI utilizes ‘Deep Learning’ as the machine learning model that imitates the human learning process to a degree with predictive analytics, and complex learning algorithms.

A good analogy describes the process as:

“To understand deep learning, imagine a toddler whose first word is dog. The toddler learns what a dog is — and is not — by pointing to objects and saying the word dog. The parent says, “Yes, that is a dog,” or, “No, that is not a dog.” As the toddler continues to point to objects, he becomes more aware of the features that all dogs possess. What the toddler does, without knowing it, is clarify a complex abstraction — the concept of dog — by building a hierarchy in which each level of abstraction is created with knowledge that was gained from the preceding layer of the hierarchy.”

In this fashion, deep learning differs from traditional linear algorithms that are dictated by the computer programmer. A deep learning model will independently sift through massive data sets to create complex statistical models from large amounts of unstructured data. This represents a new frontier in AI technology. Prior to the 21st century, access to big data sets and cloud computing were out of reach for many computer programmers.

Not everyone in the medical field sees the potential in AI recognition. This article from MIT discounts any benefit to the computer model’s ability to detect race.

“The fact that algorithms ‘see’ race, as the authors convincingly document, can be dangerous. But an important and related fact is that, when used carefully, algorithms can also work to counter bias,” says Ziad Obermeyer, associate professor at the University of California at Berkeley, whose research focuses on AI applied to health.

This understandable caution for bias by AI is the prevailing theme for a significant part of the medical community. Numerous papers and articles sound the alarm for potential abuses of AI racial recognition. However, not one study or opinion piece expanded on the potential uses for AI’s talent to discern race in medical imaging. Remember, no human experts can do this, regardless of experience or training. What if this could unlock new, highly effective therapies tailored to different races depending on the disease? Maybe this leads to discovering distinct correlations that would allow for earlier detections of cancer and other diseases. AI using multivariate analysis would give all patients an edge in their treatment plans. An entirely new realm of possibilities could open up for science, but only if the courage is there to look for it.

This may be of no value in the field of medicine, and possibly even be a feature of AI that needs to be eliminated entirely. Yet to dismiss out of hand the ability for AI to detect racial identity in medical imaging without more research into potential uses would be folly and a discredit to the goal of furthering medical science and artificial intelligence.

Guest Contributor – War Pig – 30MAR2023 – Confiscations

photog Current Events, Guest Contributors, War Pig , , , ,

The day the feds start gun confiscation is the day the 2nd US civil war begins.

I believe Biden and the left are purposely trying to destroy the USA on behalf of their owners, the Chinese, Russians and Soros.

Biden’s plan to stop gas sppliances such as cook stoves, furnaces, clothes dryers, and water heaters will only serve to further erode the power grid. California is already at the point of rolling brownouts. Imagine taking away all gas appliances and adding in mandatory electric cars to boot? Grid meltdown. Add on anything else such as a good-sized earthquake or solar flare and California will have massive blackouts and, as a result, lots of deaths. California is broke. And remember, the hospitals, etc, will be forbidden gas or fuel powered backup generators.

I have a natural gas standby generator, a gas water heater (looking at an on-demand unit to replace the tank type), gas range and a gas clothes dryer. That reduces my electrical load during outages and puts less stress on the generator, so I can basically run my whole home as if I still had line power. I can cook, wash and dry clothes and the rest on a smaller generator. All circuits are available, not just an essential few. Big Daddy Joe wants to take that from me. Good luck.
