Comment Re:Jet engines (Score 1) 54

Jet engines are quite power hungry. They are used in aircraft because they are light with respect to their power, not because they are efficient.

Most current-generation electrical power plants (except solar and wind, of course) are gas turbines, essentially jet engines, because they are very efficient.

The REAL headline and buried lede for the original post should be:

Trump guts nuclear safety regulations

“The president signed a pair of orders on Friday aimed at streamlining the licensing and construction of nuclear power plants — while panning the Nuclear Regulatory Commission for its ‘myopic’ radiation safety standards.”

We now have industry capture of the Nuclear Regulatory Commission.

Who here knows about Admiral Hyman RIckover? All of this is worth reading:

Are You Scared Yet?

I would be.

The Department of Energy is selling off more than 40,000 pounds of weapons-grade plutonium from the Cold War arsenal to nuclear reactor startups. All of which I’m sure will be thoroughly vetted and monitored, because this is done under the direction of a former board member. Yikes!

Christopher Allen Wright (born January 15, 1965) "12) is an American government official, engineer, and businessman serving as the 17th United States secretary of energy since February 2025. Before leading the U.S. Department of Energy, Wright served as the CEO of Liberty Energy, North America's second largest hydraulic fracturing company, and served on the boards of Oklo, Inc., a nuclear technology company, and EMX Royalty Corp., a Canadian mineral rights and mining rights royalty payment company.

Who IS Oklo, Inc. the "private nuclear reactor builder/operator"? Oklo is Sam Altman:

Trump Administration Providing Weapons Grade Plutonium to Sam Altman

"If there were adults in the room and I could trust the federal government to impose the right standards, it wouldn't be such a great concern, but it just doesn't seem feasible."

We're in territory where weapons-grade plutonium is being given at fire-sale prices to billionaires who's ethical boundaries include creating their own demand for otherwise unnecessary, high-risk energy projects. Guys like Altman, who get their ideas from Wikipedia articles about Ayn Rand — because they are one rung lower than people who actually READ that garbage.

But I'm sure no inventory of hot nuke metal will ever go missing.

Comment Exxon isn't a big player [Re:Price-Fixing.] (Score 3, Informative) 71

So, in response to my saying Exxon isn't a big player, you point to Duke and American Electric Power. Neither one of these is Exxon. If you had used these as examples in the first place, I wouldn't have bothered to correct you.

As for Exxon supplying fossil fuels to electric producers, yes, but they're not the big player. The primary fossil fuel used in electrical power production is natural gas, and the big player is not Exxon but BP, 16 billion cubic feet of natural gas per day in the United States. Number two is EQT, a company you probably never heard of (only a third as big a producer as BP, but still producing double the amount of natural gas as Exxon, a company primarily focused on oil.)

Exxon is not and has never been the good guys, but they're only a bit player in electrical power, and most certainly are not driving the price increases.

Comment Why give anyone control? (Score 2) 208

Why even CarPlay or Android Auto? Those are not the dubious features we should be scrambling to get "back". Both of those were bad choices to begin with, handing Google and Apple control of our in-car experience, sending them our location at all times to be sold to the highest bidder. I chose not them, and certainly not to let the car manufacturers get their drool-covered mitts on my experience.

I'd rather have a very good, solid phone holder I can slip my phone into and control everything myself. I have my own satnav I can trust (Osmand). My own music player over vanilla bluetooth. Nothing to tell me when and how I can interact with my device. No "I'm sorry Dave, I can't do that while I'm moving". I choose when I'm safe. Hell, when I'm waiting in a car wash lineup, I can play a movie from my VPN'ed home server. My phone holder is solid with aluminum clamp arms repurposed from a motorcycle, clamped to my Jeep's driver-side grab handle, which I don't need because I have the steering wheel. With an integrated magnetic couple charger, I am set.

Why are people so interested in handing this functionality over to their car? Or to Google? My experience is easy to interact with, feature rich, liberating, and ad and surveillance free.

Comment Aux In (Score 1) 208

I have a Honda with an obsolete "infotainment" system, but at least it has an Aux In next to a USB port that provides power, so I can plug in an $11 UGreen dongle and listen to whatever I feel like. If I cared there are some nice 7" 1080p screens for cheap in the Raspberry Pi space that could be shoehorned in and run at 12V. But I'd rather have no screen at all.

Funny thing is that UGreen pairs faster than any other bluetooth device I have and never doesn't work. For eleven bucks.

With the fickleness of Google and Apple there's no chance they'll even support the current CarPlay and Android Auto in 20 years. I like to keep my vehicles 15-30 years, depending on how well they handle rust.

Maybe Crutchfield will make bypass harnesses for these systems in ten years when absolutely nothing works but the screen and speakers are still useful.

We really should be looking for standards at that level, so the compute modules could be upgraded after the manufacturer abandons their platforms.

As Louis says, you shouldn't be a felon for disabling ads on your refrigerator that you never agreed to.

Price-Fixing. The media's coverage of rampant price-fixing and manipulation is laughable. The largest energy company in the country is Exxon.

I have nothing good to say about Exxon, but since the article we're discussing is about electrical power cost and demand, Exxon really isn't a major player (although in the future they could be.

Comment Re:Acid Rain? (Score 1) 30

Maybe. Acid rain originates mostly from sulfates that come from burning coal (which contains sulfur as a contaminant.) But a large portion of the Delhi air pollution comes from burning the crop residue in fields to prepare the land for the next planting. This most likely doesn't produce sulfates.

True, but bear in mind that coal contains sulfur because it is fossilized plant matter that contained sulfur while it was alive. The residual organic matter from the crops most definitely contains sulfur. It can be more concentrated in coal, but the actual ratio between carbon and sulfur is going to be in the same general area.

not even close. Coal averages 2.5% sulfur. Plant matter averages about 0.25%.

Comment Re:Acid Rain? (Score 1) 30

I think you entirely missed the point. The reason they are proposing promoting rain in the first place is so that the rain can clear the contaminants out of the air. The GP was pointing out that the tradeoff to this is that those contaminants being removed from the air in rain will mean that they end up _in_ the rain. The result of that tends to be acid rain.

Not all of it, though, so some of the pollution may include nitric oxide from internal combustion engines without pollution controls, and sulfur oxides from high-sulfur coal burned in power plants, which indeed would cause acid rain.

Apple had a culture of authenticity. Culture dies pretty hard in most cases. I think we will see the last of that culture dissipate, as it eroded so greatly under Cook and Ive. Then the extractive, enshittifying corruption will spread from Apple, too.

There really was something, that began with Jobs and Woz. It wasn't perfect, and Jobs had a way of twisting ethical stances in ends-justifying-means sophistry. But Steve Jobs would never have prostrated before Trump, proffering a solid gold token.
