People Who Claim To Worry About Climate Change Don't Cut Energy Use

kenwd0elq Re:No real surprise (710 comments)

Thanks. See? There's the scientific method working; I learned something new. Unfortunately, many of the more passionate advocates will not admit mistakes, and don't learn anything new.

Which was my original point.

People Who Claim To Worry About Climate Change Don't Cut Energy Use

kenwd0elq Re:No real surprise (710 comments)

" Science resolved. Nothing even to discuss. Period."

There speaks a man who knows NOTHING about the scientific method. "Science" isn't a thing, it's a process for narrowing in on the truth. The "science" is NEVER settled; there's always more to learn. Even Stephen Hawking is still changing his mind about how black holes work (or don't) and he's the guy who INVENTED the things. AGW is a RELIGIOUS belief, which is why we "deniers" are treated as heretics and apostates.

Remember, 30 years ago the existential crisis was the coming ice age, and 120 years ago, the existential crisis was that London was going to be 5 feet deep in horse manure.

kenwd0elq Re: No real surprise (710 comments)

That's because their claims of enviro-superiority are like medieval "indulgences", permissions to sin without penalty. So Saint AlGore flies all over the world preaching the "Stop flying!" mantra, as if he'd never heard of Skype or Webex. As Instapundit Glenn Reynolds writes, "I'll believe that there's a crisis when the people who are telling me it's a crisis start ACTING like it's a crisis."

Two Earth-Like Exoplanets Don't Actually Exist

kenwd0elq Next Great Example of Planet Hype (102 comments)

http://apod.nasa.gov/apod/ap14...

Gleise 832C is another "planet" with a remarkably Earthlike "artist's rendering" of an exoplanet in a very close orbit around a smallish star. Is this a real planet candidate, or another case of "sunspot confusion"?

Two Earth-Like Exoplanets Don't Actually Exist

kenwd0elq Re:Yeahhh (102 comments)

Ditto here. The "New planet may support life!!!! meme is so COMPLETELY overblown based on a telescope that detects occultations, and doesn't generate any images. The "artist's renderings" were way off in fantasyland, entirely unsupported by the data.

New Class of Stars Are Totally Metal, Says Astrophysicist

kenwd0elq Re:One slight problem with that ratio... (119 comments)

Fusion of hydrogen into helium produces a LOT of energy. Fusion of helium into carbon produces less. In physics terms, it's the "packing fraction" curve, which can show you what energy you'd get out if you fuse elements together.

Iron is at the bottom of the packing fraction curve; when you fuse other stuff into iron, you're getting out the dregs of the fusion energy, partly because it takes higher and higher pressures and temperatures for fusion to occur for heavier elements.

When you get to the pressure and temperature points where iron fuses into still heavier elements, it begins to EXTRACT energy - from the core of the star. Stars exist in a delicate balance between the heat and pressure that tries to blow them apart, and the gravity that tries to crush them together. Take heat OUT of the core of the star, and there's less internal pressure - and gravity starts to win. The core will collapse, generally abruptly, and a crushing "rebound effect" will accelerate the heavy fusion, extracting MORE energy, leading to a core collapse supernova. The star explodes, leaving a black hole or pulsar at the center and blasting a lot of the stellar material back into space.

Which is where we got the iron for our blood, or the gold for our jewelry - blasted out of a supernova. Probably MANY of them.

New Class of Stars Are Totally Metal, Says Astrophysicist

kenwd0elq Re:Fission? (119 comments)

In fact, the fusion of anything that produces an element heavier than iron will extract energy from the star's core, hastening its collapse.

New Class of Stars Are Totally Metal, Says Astrophysicist

kenwd0elq Not the Usual Definition of Metal (119 comments)

In astrophysics, the term "metal" normally applies to any element heavier than lithium. Carbon, silicon, even gasses like oxygen and nitrogen, are "metals". We're not talking about star remnants that are primarily iron or lead or uranium. Gold would be right out.

Gecko Feet Inspire Hand-Held Spider-Man Paddles

kenwd0elq Re:Uh Oh! Here comes Iron Man (64 comments)

The problem with trying to USE Van der Waals forces for anything is that in order to stick together, both surfaces must be microscopically smooth; the sort of "smooth" that would make plate glass or mirrors look like "volcanic rock under a magnifying glass". "Reflecting telescope mirror" smooth. Making materials that smooth - and KEEPING them that smooth - is going to be a challenge.

As physics, it's pretty neat. From an engineering perspective, it's going to be a problem.

ISS-Above Tells You When the International Space Station is Overhead (Video)

kenwd0elq Why Bother? (59 comments)

SpaceWeather.com has a "Flybys " website; enter your zip code (USA) or Lat/Long (Anyplace) to see a list of overflights of the ISS and a couple dozen other satellites that are bright enough to see.

http://www.spaceweather.com/fl...

The web site is free; they have an Android and iOS app for five bucks, I think, that sounds an alarm.

More than good enough. Although I can see how designing your own device and programming it yourself is more impressive than buying an app or navigating to a web site.

Hundreds of Cities Wired With Fiber, But Telecom Lobbying Keeps It Unusable

kenwd0elq Re:Government of the people ? (347 comments)

Agree completely. Here's a classic example of how foolish, supposedly "well meaning" citizens screwed themselves....

http://www.mystatesman.com/new...

POLITICS: Woman who voted for every Austin, TX tax increase discovers that now she can’t afford to live there. “I have voted for every park, every library, all the school improvements, for light rail, for anything that will make this city better. But now I can’t afford to live here anymore. I’ll protest my appraisal notice, but that’s not enough. Someone needs to step in and address the big picture.”

Whenever "We the peepul" allow the government to "take care of us", we allow rapacious wolves to take over our lives. Democrap, Rinopublican, Socialist, "Green" - most political parties will promise you ANYTHING to get the power to jail you and steal everything that you have.

It might - just MIGHT - still be possible to roll it all back. Probably not, but I'm the eternal optimist. Vote Libertarian if possible, or Tea Party - and then roll THOSE crooks out of office at the next election. We don't want to "control government spending"; we want to abolish departments and sell their buildings. I want to revoke their pensions and jail a few. Cut all government salaries by a third - and then do it again the next year. We want to make Washington D.C. a ghost town. As it is, 9 of the ten highest income zip codes are in or next to the Beltway. Legend says that in ancient India, new rulers were weighed every year, to see if they had gotten fat at their subjects' expense. It ought to be illegal for a government official to own a luxury car or a boat or a swimming pool; those things mean they're making too much money.

I blame air conditioning. Washington D.C. used to be a fetid, barely inhabitable swamp. That's why Maryland and Virginia were willing to give it up. Air conditioning lets the parasites live in comfort. Ban air conditioning within 100 miles of DC, and just SEE how quickly the government shrinks!

Strange New World Discovered: The "Mega Earth"

kenwd0elq Re:Science Writers: Stop Causing Us Intellectual P (147 comments)

Marketing people would much rather use the word "more" than the word "less", and bigger numbers rather than fractions. So in trying to say "uses one-eighth as much", it comes out as "saves 87% MORE than".

Optical Levitation, Space Travel, Quantum Mechanics and Gravity

kenwd0elq Re:An Old Idea Resurrected - Again (82 comments)

"Proven" is, perhaps, the wrong word. "Made to be practical", perhaps. A $5 radiometer from a craft store proves quite readily the idea that light has pressure. The trick will be, as with the nuclear fusion proposals that are perhaps twenty years in the future - and have been "20 years in the future" for thirty years now, to make it big enough and practical enough that we can extract usable amounts of energy from it.

Optical Levitation, Space Travel, Quantum Mechanics and Gravity

kenwd0elq An Old Idea Resurrected - Again (82 comments)

There's nothing new about the idea of spacecraft being propelled by light pressure. There was an Arthur C. Clarke story published in "Boy's Life" in the early 60's about sunlight powered "sailing yachts" in a race from Earth orbit to the Moon. Or the Niven story "The Fourth Profession", in which an alien trading ship arrives at Earth, wanting humanity to build a launching laser to send the crew on the next leg of their journey.

And it's been 30 years since Niven & Pournelle published "Mote In God's Eye" in which an interstellar probe riding a the combined beam of battery of laser cannons arrive in human space.

So if actual human physicists are finally going to get around to proving the concept, so much the better!

Kids With Wheels: Should the Unlicensed Be Allowed To 'Drive' Autonomous Cars?

kenwd0elq Re: Would You Leave This Child At Home Alone? (437 comments)

There's this great tool called "Google". Or use DuckDuckGo. Or any search engine of your choice. You won't believe the results of my research, so do your own.

But this is somewhat far afield of the original "Should the unlicensed be allowed to 'drive' autonomous cars. No.

Kids With Wheels: Should the Unlicensed Be Allowed To 'Drive' Autonomous Cars?

kenwd0elq Re:Would You Leave This Child At Home Alone? (437 comments)

You also won't find any law prohibiting a child from nibbling his Pop-Tart into the shape of a gun, but a 6-yo was suspended from school for having a "weapon" - or anything which a mentally-disturbed teacher might think LOOKED like a gun. Yes, it happened.

ThisIsTrue.com is a weekly compilation of bizarre but true news stories; search for the "zero tolerance" ones.

But here are a few selections from a Google search for "parents arrested for leaving children alone".

kenwd0elq Re:Would You Leave This Child At Home Alone? (437 comments)

Go ahead; leave your 10-yo child at home alone. When CPS takes your children and the cops arrest you for "child endangerment"- which HAS HAPPENED - your (true) argument that you can't find any law about it WILL NOT get your kids back or your bail reduced.

The problem is that the bureaucrats who are supposed to ADMINISTER the law often, with judicial connivance, are making up the law as they go along.

Sorry; he neglected the tag, and it was not obvious to me that sarcasm was his intent. If it was, I apologize - but the problem is far too real.
