Submission + - Wind Power Economics costs aren't declining (ref.org.uk) 1

Stonefish writes: It is often quoted that the cost of wind power has been declining and while business should be booming, in 2022 all major wind farm manufacturers lost money. https://watt-logic.com/2023/06...
Gordon Hughes, a former Professor of Economics at the University of Edinburgh, and senior adviser on energy and environmental policy at the World Bank published Wind Power Economics, Rhetoric and Reality for the Renewable Energy Foundation https://www.ref.org.uk/publica.... This shines a light on the fundamental economics of these projects and the results sit in stark contrast to the conventionally accepted wisdom. The data has been pulled from publicly available sources where wind power companies must publish their results to participate in the UK Government's rebates program.
The summary is that Wind farm costs are increasing and that companies appear to be significantly underbidding on contracts, hoping that they can renegotiate subsidies. This process has already begun with companies claiming price increases due to scarcity and inflation even though their returns are indexed to inflation and it was clear that turbine manufacturers can't continue to manufacture at a loss.
I'm hoping that this isn't true however I'm struggling to refute this analysis, sources such as Lazard focus on LCoE cost not the overall economics of the project.
I was hoping that Slashdot might be able to provide some form of rebuttal

Submission + - What happens when you cross a gas turbine with an internal combustion engine? (driving.ca)

Inzkeeper writes: Here is another radical replacement for the traditional combustion engine.
Check out the Astron Aerospace H2 Starfire Omega 1
. Astron Aerospace is makes turbines for commercial jet engines.
However, they have come up with a novel way to make an ICE engine with a turbine configuration.
This raises engine thermal efficiency from 35% for ICE engines to 80%.
From https://www.hotcars.com/omega-...:

Even though the Omega 1 is around the size of a regular sewing machine, it packs a punch well above its weight. The entire engine only weighs in at around 35 lbs and the system produces in the region of 160 hp and 170 lb-ft – around the same as a non-sporty turbocharged 2.0-liter 4-cylinder. Unfortunately, Astron Aerospace is not able to tell the cubic size of the engine, but we expect it to follow the traditional rotaries’ smaller capacities.

Although there is a working prototype, there are still many hurdles to overcome to get this to mass market.

Submission + - Climate scientist gets published in Nature by omitting key details (thefp.com) 2

Okian Warrior writes: [[Note to editors: This is an important topic that should be discussed on slashdot, and there is no better place for this discussion. You don't need to suppress opposing viewpoints if you are on the right side of an argument, that's not something the good guys do.]]

Climate scientist reports on getting a paper published in Nature:
"I just got published in Nature because I stuck to a narrative I knew the editors would like. That’s not the way science should work."
"So why does the press focus so intently on climate change as the root cause? Perhaps for the same reasons I just did in an academic paper about wildfires in Nature, one of the world’s most prestigious journals: it fits a simple storyline that rewards the person telling it. "

Submission + - Harvard Now Ranks Dead Last on Free Speech

christoban writes: This year, Harvard has finally been ranked as America’s worst college for free speech by The Foundation for Individual Rights and Expression (FIRE). The Ivy League university's approach has been labelled 'abysmal,' with a rating of 0.00, down from 55.5 in 2021-22 and 34.5 last year. The university was the only one to receive the lowest possible score. According to the article, the real figure is “more than six standard deviations below the average” and was based in part on nine deplatforming attempts at Harvard since 2019. The report sampled over 50,000 undergraduate students nationwide.

He even says where he is, which isn't downtown Chicago itself. He's in the suburbs, just like you're talking about. And secondly, he even says that those few days that are too cold you definitely need the "pump" to have "emergency/backup" regular heating coils. But by my understanding, that's a standard feature. So it's the same device on your house doing the work, and no worse than electric the rest of the time.

You seem well-informed, and making genuine arguments, but I'm not quite sure what you're advocating. If it's electric, then that's what Heat Pumps are, but better, and no worse during the worst part of the year. If you're advocating gas, then it's better 1 month of the year? Or less? You agree that the 32F thing is bullshit, right? Where I live in Nova Scotia, considerably colder, and you can't get a heat pump up here unless it heats when outside ambient is -15C I think (around zero F).

Or what else are you advocating? I agree that a cheap method not to freeze to death in the dark is essential, but I'm not sure where you're coming from with your argument.

Submission + - Popular .Net mocking framework Moq extracting user emails, nagging for funds (snyk.io)

SoCalChris writes: The latest version of the popular .Net mocking framework Moq has started extracting user's emails from git and checking if they sponsor the project, and throwing a build warning if they don't. The framework is hashing the email and sending it to a closed source third party for verification. In addition to the privacy concerns, this is likely breaking numerous EU privacy laws, and breaking builds for projects that treat warnings as errors. Numerous large projects, such as Stack Exchange are already looking to replace Moq with alternatives. There's a good post about what it's doing here, as well as a reddit thread full of developers discussing the implications. While funding for large widely used OSS projects is a topic that needs to be addressed, this is the wrong way to go about it.

K is just as arbitrary. It's still based around water at an arbitrary pressure, which is just a measurement of the pressure at Earth's surface. So the divisions aren't based on anything more than the freeze/boil points, and saying "It's 100 between these!" But if you alter the pressure even a little bit, then the division would change. Yes all of Metric is based on "this is a kilogram, now work out the rest" for a lot of it, but temperature isn't. Still arbitrary to the "average" pressure of Earth's surface. So still a few arbitrary selections.

Fun thought experiment: what if a kilogram had been defined to be as close to identical to an Imperial (let's say the British Empire version) pound as was measurable? Everything else would change (except temperature, see above), showing how arbitrary Metric is as well.

Browser integration only occurs with both an addon for the browser, and explicitly setting it up in the application to handshake with the browser (you have to click a button on the application side, it's not automatic from the browser), and then when going to the sites an additional explicit acknowledgement on top of that, given that you even gave the entry a website association in the first place (if your entry doesn't have a URL field, it doesn't associate).

Pretty secure by default, and that's what really matters, not what options you can optionally enable.

Slight alternative, same idea: KeepassXC. It's actually open source, unlike the base Keepass (which I used to use). I used Keepass for years, and it's great, but I think that "XC" is better both philosophically, as well as features, like browser integration. And just like regular keepass, if you want it on the cloud, put your encrypted file on Google Drive, or your other internet location of choice, and you're good.

Submission + - SPAM: Amazon Locks a Man Out of His Smart Home Over Racism Allegations

schwit1 writes: Brandon Jackson recently found himself in the midst of a problem. On May 25, he discovered that his smart home, which is tied to Amazon, was no longer doing that which he was paying for it to do. In a piece on Medium, Jackson noted that his primary way of interfacing with all of this wondrous technology is through Amazon Echo via Alexa. And lo and behold, suddenly nothing would respond to his requests or commands.

At first, Jackson thought he had possibly been hacked. But he goes to great lengths to keep his passwords secure. So with security issues off the table, what could it have been? The answer is stranger than you think. Or maybe it is part and parcel of 21st century America, and should serve as a lesson for those who are so enamored of having a “House of the Future.”

On May 24, a package was delivered to Jackson’s home. His doorbell camera was programmed to say, “Excuse me, can I help you?” For one reason or another the driver who was walking away from the door and wearing headphones decided that the doorbell camera had somehow uttered a racial slur. The driver filed a complaint andlights out, so to speak.

It took a week, but Jackson was eventually able to gain access to his devices once again. He wrote:

Through sharing my experience, I hope to encourage Amazon to reform and rethink their approach to handling such situations in the future. It’s essential for customers to feel confident in the security and reliability of their services, especially when those services are integral to the functionality of their homes. It’s time for Amazon to take a more customer-focused approach to problem-solving and conflict resolution.

The problem, however, is not with Amazon’s customer service. Well, it is in that any large company can be painfully slow in reacting to the needs of a customer or any problems with products. But the issue is with the Almighty Algorithm (blessed be its name) that did exactly what it was supposed to do. It received an accusation of racism and doled out what it deemed to be the appropriate punishment. This is what one risks when one turns one’s life over to a corporation. One wrong move and it all goes away with a flip of a switch. If that. Note that Jackson did not make a racist remark. He only needed to be accused of one to have his life turned off.

Submission + - Boeing delays Starliner launch ... again (arstechnica.com)

xanthos writes:

A Boeing official said Thursday that the company was "standing down" from an attempt to launch the Starliner spacecraft on July 21 to focus on recently discovered issues with the vehicle. Mark Nappi, vice president and program manager for Starliner, said two spacecraft problems were discovered before Memorial Day weekend and that the company spent the holiday investigating them. After internal discussions that included Boeing chief executive Dave Calhoun, the company decided to delay the test flight that would carry NASA astronauts Suni Williams and Butch Wilmore to the International Space Station.

TLDR; the parachute cords might not be strong enough and the tape that holds down all the wiring harnesses might go up in flames. Manned flight score: SpaceX 9 — Boeing 0

Comment Re:This is good (Score 1) 167

the laws (and highest secular laws, constitutions) should be written soundly enough that judges need to outright ignore the text (ie: Canada, Living Tree Doctrine, etc) in order to go against it.

It's impossible for the law to be written in a way that covers every case, since reality is a fractal of ever-complicating edge cases.

Agreed, but that should still be the goal. It seems like many laws are written with obvious loopholes for exactly the opposite purpose. Almost anything allowing "discretion" for prosecution just opens things up to malicious prosecution against whomever is in power's enemies. If a law is broad enough to allow such, it shouldn't exist.

So no matter how specific you are, you still need judges, I agree, but ideally it should be extremely rare for their personal politics to have significant influence, because the laws are written well. This won't (and can't) solve all the problems, but it's a good rule of thumb to start with.
