The point I'm trying to make is that we should have some government-guaranteed loans for the purchase of exotic cats.

Here comes that Musky Scent again

2 Comments
Elon Musk revealed as one of the largest donors for a House Republican PAC:

Filings show that the Tesla and SpaceX CEO donated $38,900 to the PAC, which is dedicated to keeping Republicans in control of Congress. The PAC raised over $8 million in quarter two, according to filings compiled by ProPublica.

The top donors of the PAC include Sheldon Adelson, the Vegas casino magnate, and Robert McNair, the owner of the NFL's Houston Texans. Although Adelson and McNair's contributions far outweighed Musk's -- Adelson and McNair each gave $371,500 respectively, while Musk gave $33,900 -- Musk was one of the top 50 donors of the PAC. [...]

"Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world," Musk said on Twitter at the time.

One year later, the tech entrepreneur has taken active measures to help the Republican Party maintain Congress. The reports on Musk's political contributions is just another data point marking Musk's nonsense.

The other latest example was Musk's voluntary involvement in the Thailand cave rescue. [...] One of the rescue leaders, Vern Unsworth, ridiculed Musk in a video interview released on Friday.

"It just had absolutely no chance of working. He had no conception of what the cave passage was like... It wouldn't have made it the first fifty meters in the cave. It was just a PR stunt," the rescuer said. "He can stick his submarine where it hurts." [...]

Musk's feud with the cave rescuers resembles the Twitter debate he engaged in after proclaiming he was a socialist. Musk trolled some socialists by explaining his view of socialism, which remarkably sounded a lot like capitalism. [...] for him to refer to himself as a socialist appears to be another troll attempt from one of Twitter's most persistent trolls. (Musk just last week tried to say that "billionaire" has become a derogatory term.)

Musk's donations to the GOP may have catapulted him to all-world troll status.

I know a lot of you temporarily-embarrassed millionaires think he's super cool because, like, wow, rockets, but seriously, fuck this guy.

More trolling, or just cluelessness? He stirs up the fanboys by naming his products after ships from Iain M. Banks, but it's too bad that he fundamentally misunderstood those books:

JR: Many critics and reviewers have claimed that the Culture represents the American Libertarian ideal. Given that this is clearly not the case, how do you characterise the politics of the Culture?

IB: Really? I had no idea. Obviously I haven't read the output of the relevant critics and reviewers. Let's be clear: unless I have profoundly misunderstood its position, I pretty much despise American Libertarianism. Have these people seriously looked at the problems of the world and thought, 'Hmm, what we need here is a bit more selfishness'?... I beg to differ. This is not say that Libertarianism can't represent a progressive force, in the right circumstances, and I don't doubt there will be significant areas where I would agree with Libertarianism. But, really; which bit of not having private property, and the absence of money in the Culture novels, have these people missed? The Culture is hippy commies with hyper-weapons and a deep distrust of both Marketolatry and Greedism. One rests one's case.

It could be that Musk does believe that a post-scarcity society would be awesome -- but there's as really good reason for that. As a billionaire, he already lives in a post-scarcity society. It's just one that admits vanishingly few people as its citizens.

@cstross: Attn @elonmusk -- I knew Iain and I'm pretty sure he'd have trenchant and unkind things to say about your stance on unions, workplace sexual/racial harassment, and socialism in general.

@Richard_Kadrey: Any gazillionaire who calls himself a Banks-inspired utopian anarchist is just a Libertarian who jerks off to Wired.

Previously, previously, previously, previously, previously, previously.

Well, Musk, alas, but my defending of your audacious plans is hereby ended since you want to help destroy lives and democracy. Enjoy your world.

Just last month the ACLU confirmed that Elon is one of their largest contributors. AFAI recall, he gives amounts to both parties and is registered as an Independent.

Retiring Worn-Out Wind Turbines Could Cost Billions That Nobody Has

2 Comments
schwit1 shared this article from Energy Central News: Estimates put the tear-down cost of a single modern wind turbine, which can rise from 250 to 500 feet above the ground, at $200,000... Which means landowners and counties in Texas could be on the hook for tens or even hundreds of millions of dollars if officials determine non-functional wind turbines need to be removed. Or if that proves to be too costly, as seems likely, some areas of the state could become post-apocalyptic wastelands steepled with teetering and fallen wind turbines, locked in a rigor mortis of obsolescence.

Companies will of course have the option of upgrading those aging wind turbines with new models, a resurrection of sorts. Yet the financial wherewithal to do so may depend on the continuation of federal wind subsidies, which is by no means assured. Wind farm owners say the recycling value of turbines is significant and recovering valuable material like copper and steel will cover most of the cost of decommissioning... Yet extracting valuable materials from the turbines is not as easy as it sounds... "The blades are composite, those are not recyclable, those can't be sold," said Lisa Linowes, executive director of WindAction Group, a nonprofit which studies landowner rights and the impact of the wind energy industry. "The landfills are going to be filled with blades in a matter of no time...."

Unlike Duke Energy, some of the smaller wind farm companies operating in Texas, with fewer financial resources, may be tempted to just walk away when aging turbines no longer spin a profit. Linowes believes such moves may begin occurring even before wind turbines outlive their useful life as manufacturing warranties on the big turbines expire. "At what point does the cost of maintenance tip over to the point it's not worth maintaining a turbine?" she said. "We're in something of an unknown or uncertain territory... It could be a very ugly situation in the next five years when we see turbines need work, and are no longer under warranty and not generating enough electricity to keep running them."

are companies allowed to simply walk away from dams/oil/gas/coal/nuclear plants when they're unprofitable currently?

I'm not entirely sure. I think it depends on the kind of plant and the hazards that it presents. I imagine they need to be made safe, like with a nuclear plant, operating it until the fuel has been expended, and cleaned up, but I don't think there's any requirement to remove the building, the company probably continues to own the land, until it's sold for another purpose. Composite blades, are they glass fiber composites or carbon? Those could be considered a means of removing carbon from the environment if they're carbon fiber composites. I wonder if land owners could step in and refurbish them to run on their own.

Bandpass Filters from the CNC Mill

1 Comment

A bandpass allows a certain electrical signal to pass while filtering out undesirable frequencies. In a speaker bandpass, the mid-range speaker doesn’t receive tones meant for the tweeter or woofer. Most of the time, this filtering is done with capacitors to remove low frequencies and inductors to remove high frequencies. In radio, the same concept applies except the frequencies are usually much higher. [The Thought Emporium] is concerned with signals above 300MHz and in this range, a unique type of filter becomes an option. The microstrip filter ignores the typical installation of passive components and uses the copper planes of an unetched circuit board as the elements.

A nice analogy is drawn in the video, which can also be seen after the break, where the copper shapes are compared to the music tuning forks they resemble. The elegance of these filters is their simplicity, repeatability, and reproducability. In the video, they are formed on a CNC mill but any reliable PCB manufacturing process should yield beautiful results. At the size these are made, it would be possible to fit these filters on a business card or a conference badge.

How to Spend July, 1612

1 Comment and 3 Shares
Wenceslaus Hollar, Summer (1644)

"In July. Now arrives the Sommers Solstice, which with the fiery Dogge turnes the moisture of our bodies into parched exhalations, which we commonly call cholerick symptomes. And therefore shunne roast or broyled meates. Shunne salt meates, Bacon, and strong Beefe. Spare not to drinke Ptizans, Endive, or Succory waters, which coole the liver. Now you may boldly sleepe in the after noone, so that it be not presently after dinner, and not above an houre. Beware of bloud-letting, Physick, and venerous acts. When you are emptie, bath your selfe in colde water, for that recreates the animall powers."  
William Vaughan, Approved Directions for Health
It's July, and you know what that means: no grilled burgers, no sex, just cold baths and endive water.

On second thought, just boldly sleepe until August.

I feel for Guido, the thing that he loved, that became his life's work, has now thoroughly burned him out. I blame the "community".
