Can Spinlaunch throw rockets into space?

maestro156 says...

Yeah, 20000ft is roughly 6km. The air density is about 1/2 but from what I can determine that doesn't equal 1/2 air resistance, but something more like 90-95% air resistance of sea level.

Having said that, I haven't studied aerospace engineering, so I might be getting the details wrong.

There are definitely some minor advantages to building on a mountainside, but I don't think they outweigh logistical difficulties under normal circumstances.

The idea has a good bit of scifi (and probably scientific) history behind it though. I believe Heinlein used a railgun cargo launcher from the moon in Moon is a Harsh Mistress and a mountainside sled rocket in one of his earlier books.

Project Rho is a great resource for hard scifi and rocketry research for writers. http://www.projectrho.com/public_html/rocket/surfaceorbit.php is the link to a page that discusses maglev, railguns and rocketsleds.

I’m thinking Mt Chimborazo in Ecuador…at over 20000 ft, it’s peak it the farthest from the center of the earth (while not being the highest above sea level thanks to the equatorial bulge).
Sure, it doesn’t remove air resistance or friction, but halving it, even cutting it by 1/3 is a massive leap in efficiency and negates much of the extreme engineering and materials needed to overcome the friction….plus, as you mentioned, there’s the rotational speed advantage from launching on the equator vs Florida.
Also, while extremely minor, there’s also a slight reduction in gravitational pull at those heights. A joule saved is a joule earned!

And today, memos from the Trump Whitehouse detailing the first coup attempt were released, how they wanted Pence to simply discard the electoral votes from 7 states that went to Biden so no one would get 270, then the (at the time) Republican house would each get one vote, with Republicans voting for Trump.

Mind you, this scheme was totally illegal, unconstitutional, and anti democratic. Pence had no legal reason or method to simply deny the votes from 7 states, and he refused to go along. If you recall, that's why Trump's coup crew was chanting "hang Mike Pence" and built a gallows to do it at the second failed attempted coup for Trump. That's why Pence refused to leave congress with Trump's secret service detail, he was certain they would either murder him or deliver him to the crowd that would.

BTW...under 500 showed up to support those treasonous traitors from Jan 6...not a single Republican representative. Not even MTG or Bohbert. Even they gave up on the lie.

Undercover: EXPOSING MAGA Hypocrisy on Afghanistan

newtboy says...

The end of the war and resumption of the Third Indochina War would precipitate the Vietnamese boat people and the larger Indochina refugee crisis, which saw millions of refugees leave Indochina (mainly southern Vietnam), an estimated 250,000 of whom perished at sea.
The war exacted an enormous human cost: estimates of the number of Vietnamese soldiers and civilians killed range from 966,000 to 3 million. Some 275,000–310,000 Cambodians, 20,000–62,000 Laotians, and 58,220 U.S. service members also died in the conflict, and a further 1,626 remain missing in action. -wiki

So, millions fleeing as refugees, hundreds of thousands died in their attempts to escape, tens of thousands of allies killed by the VC, far more weapons, vehicles, and equipment left abandoned (and less of it decommissioned) to the enemy and a similar abandonment of the government we had been supporting. The scale of Vietnam was exponentially larger, so were the losses when we retreated. How is Kabul worse than that?

Please explain in detail how Kabul is worse. My guess....you've got nothing.

Yeah, I'm curious as well.

Did they do it mimicking how nature works, by pumping different temperatures in different places in the room, etc.?

What's with the lack of details?

Cool stuff.

Day of Rage: How Trump Supporters Took the U.S. Capitol

luxintenebris jokingly says...

stolen? 6M is a hell of a heist. AZ & GA? pretty sweet haul. what is obvious is that if this was true, it took tight organization, supreme attention to detail, and wildly deft implementation. talking superior leadership and a task force of the finest to pull it off. if they are that good - let them keep the W.H and give them the rest of Congress!

the nation wants nat'l healthcare, better educational systems, intelligent ideas - folks that can solve problems. Or just, all the things the GOP can't/wouldn't provide or structure. rather have folks that can figure out how to do the impossible, fashion plans that work on the first take, and accomplish miracles.

that's your inadvertent testimony; they're so bad they're good!

fake news? honestly, don't believe you could source where you bought your morning cereal.

put the other comments under "what can he be thinking". kind of like this news...

Trump didn't do anything wrong

JiggaJonson says...

Whatever you say. They kept very detailed records of on the books and off the books transactions (ironically their illegal expenses are also very detailed).

Tax evasion. All there. Black and white. Clear as crystal.

And we got trump saying it over and over. 'I don't pay taxes because I'm smart'

And we got trump junior saying exactly "my dad paid for his private school" https://m.facebook.com/DonaldJTrumpJr/videos/1262946037499155/

Posted it himself. What he's describing is tax evasion.

Tell me he did nothing wrong. Those tax evasion charges are easy to beat I bet. Just ask Al Capone.

Land of Mine Trailer

newtboy says...

Thanks…I like to think what I cook up is entertaining, even when the menu doesn’t appeal.

Not kill kill kill, but definitely a lack of sympathy if it happened to some. I have no sympathy or tolerance for nazis and fascists, and I don’t see a thing wrong with that. Their atrocities at the time were unfathomable, and the youngsters could be more zealous and hateful than the adults.
I also learned about WW2 at an early age, preschool or kindergarten, I had an uncle who fought on a mobile howitzer in almost every major battle in Europe after D day, and helped liberate one of the smaller concentration camps, I can’t recall which one off hand. I heard first hand about man’s inhumanity towards man in details too graphic for children.
It’s just my worthless opinion though, it’s not like I pass judgment at The Hague or hunt down aged nazi youths. Who cares if I don’t sympathize with one group of young soldiers’ plight from almost 80 years ago? War is hell for all involved, there’s just not enough empathy for everyone.
I think the Nazis earned my disdain, if I don’t give it to them they might try to earn it again!

Yep, I’m on the West coast, in the one spot not baking like an oven, Humboldt, Ca. coast. We’re having low 70’s but overcast. I could use some more sun and warmth.

Who was the nazi?
What are my choices? In what context?
With no criteria, there are so many to choose from… I think I’ll take Mengele for the block.

Land of Mine Trailer

newtboy says...

Big assumption. Many Hitler youth made the choice to fight for Germany, and joined on their own before children were being drafted.

As for those that were conscripted, is it your position that draftees are somehow immune from responsibility for murdering their neighbors, women, children, rapes, burning towns, or planting millions of landmines on foreign soil, etc? How convenient for them. I don't believe that's a popular or legal position.

I take responsibility for my actions. If their fate was mine, I would be eternally grateful I was treated so much better than I would have treated them if the tables were turned. I would be part of an invading Nazi army, trying to undo just a tiny bit of the damage we had caused, doing so at the direction of my superiors just like when I caused the situation. I would deserve execution, not release. This assumes I wouldn't have the spine to refuse to be a Nazi and be imprisoned or executed.

If the majority of Germans weren't complicit, the Nazis would have never come to power. You give them far too much credit. From the holocaust encyclopedia- "Opposition to the Nazi regime also arose among a very small number of German youth, some of whom resented mandatory membership in the Hitler Youth." Same with adults, the opposition was a minority by far, not the majority of Germans. Who told you that?

"Survived the fighting"? "Here"? "They"? Please finish your thoughts so they have meaning. You seem to be equating Nazi soldiers with the Jews they tried to eradicate. What?!?

The Geneva convention we know today was ratified in 1949. The accords of 1929 were found to be totally insufficient to protect POWs, civilians, infrastructure, etc. Yes, Germany did appear violate it's vague provisions....so did the allies. That's why it was strengthened in 49.

https://en.m.wikipedia.org/wiki/Geneva_Conventions

What provision of the 1929 version do you claim this violates?

Articles 20, 21, 22, and 23 states that officers and persons of equivalent status who are prisoners of war shall be treated with the regard due their rank and age and provide more details on what that treatment should be.
Or
Articles 27 to 34 covers labour by prisoners of war. Work must fit the rank and health of the prisoners. The work must not be war-related and must be safe work. ("Safe" and "war related" being intentionally vague and unenforceable).
Please explain the specific violation that makes mine removal a "war crime". It's not war related, the war was over, and it's "safe" if done properly.
Since this was done at the direction of German officers, the convention as written then doesn't apply.

Death camp!!! LOL. Now I know you aren't serious.
"The removal was part of a controversial agreement between the German Commander General Georg Lindemann, the Danish Government and the British Armed Forces, under which German soldiers with experience in defusing mines would be in charge of clearing the mine fields.
This makes it a case of German soldiers under German officers and NCOs clearing mines under the agreement of the German commander in Denmark who remained at his post for a month after the surrender - this means Germany accepted that they had responsibility to remove the mines - they just had far too few experienced mine clearance experts and far too many “drafted” mine clearers with no real experience in doing so." So, if it's a war crime, it's one the Germans committed against themselves.

I'm happy to say that anything done to a Nazi soldier is ethical, age notwithstanding. Many Nazi youth were more zealous and violent than their adult counterparts. Removing their DNA from the gene pool would have been ethical, but illegal. Taking their country to create Israel would have been ethical, but didn't happen.

At the time, there were few mechanical means of mine removal, they didn't work on wet ground, they required a tank and that the area be pre-cleared of anti tank mines, they often get stuck on beaches, and had just over a 50% clearance rate, cost $300-$1000 per mine removed, and they were in extremely short supply after the war. The Germans volunteered in this instance. Now, the Mine Ban Treaty gives each state the primary responsibility to clear its own mines, just like this agreement did.

So you know, the film is fiction, not history. Maybe read up on the real history before attacking countries over a fictional story. History isn't nearly as cut and dry as it's presented, neither are war crimes.

psycop said:

These boys neither chose the age of conscription nor to go to war. Given their age and the time in the war, they would have been forcably made to fight. If you had the misfortune to be born then and there, thier fate could be yours.

Being in the German army did not imply being a Nazi, the majority of the German population were victims as well, pointlessly lead to slaughter by monsters.

Those of them that would have survived the fighting ended up here. They didn't feed them. They worked until they died. They expected them to die. They wanted them to die.

The Geneva Conventions were signed in 1929 making this an official war crime if that's important to you. I'd say the law does not define ethics, and I'd be happy to say this is wrong regardless of the treaty.

As for alternatives for mine clearance. I'm not a military expert, but I believe there are techniques, equipment, tools or vehicles that can be used to reduce the risk to operators. Frankly it's besides the point. Just because someone cannot think of a solution they prefer over running a death camp, does not mean they are not free to do so.

If you have the time, I'd recommend watching the film. It's excellent. And as with most things, particularly in times of war, it's complicated.

Arizona secretary of state, Katie Hobbs sent a letter to the Arizona attorney general yesterday asking him to please investigate Donald Trump. And of course his close allies, Rudy Giuliani, and possibly even Sidney Powell for possible election interference in the state of Arizona.

Here's what happened in case you missed it last week, it was revealed that both the Trump white house and Rudy Giuliani on separate occasions and on multiple occasions made phone calls to officials in the state of Arizona following the November election, trying to get them to stop the counting, begging to be called back. In fact, it got so bad, the Arizona Republic detailed two separate attempts by Trump to reach Republican supervisor Clinton Hickman in the weeks after the election, as the president's allies sought to alter the election results in a state he narrowly lost to Democrat Joe Biden at the time, Hickman was chairman of the board of supervisors, the elected body that oversees elections in the state's most populous county, Maricopa. Hickman received the first call from the white house switchboard on December 31st while he was out celebrating the coming new year with his wife and friends, he let the call go to voicemail.

Second call came on the night of January 3rd after the Washington post published a recording of Trump's hour long phone call with Georgia secretary of state Hickman sought to avoid talking to the president because of ongoing litigation, any let the call go to voicemail and yes, for the record, the Arizona Republic does in fact have those voicemails where you can hear what they were trying to do. Then of course, Rudy Giuliani steps in, he starts emailing or I'm sorry, texting and calling the chairwoman of the Arizona Republican party, trying to get her to somehow interfere, stop the counting of the votes. Honestly, it is pretty much identical to what these idiots were doing over in Georgia, trying to get them to stop the vote, trying to get them to go find the votes as Trump said, and let's not forget... Trump is already under criminal investigation in Georgia. I know we all get distracted with New York, but there have been two grand juries empaneled in the state of Georgia regarding Donald Trump's potential criminal election interference in that state. That's a big deal that everybody seems to have forgotten about.

And now the same thing might happen in Arizona. There's a catch here. Arizona's attorney general, a Man by the name of Brenna Vich Is running for US Senate as a Republican. So he's got a lot, uh, got a lot at stake here. He can't PISS off Republicans by investigating Donald Trump.

Brenna Vich did, in fact, support Arizona's sweeping new voter suppression laws.

Edit: btw, multiple Republicans including but not limited to McConnell have gone public with their plan of hoping they can cause maximum chaos and division for the next 18 months because it will help them successfully block any and all legislation, then they can blame the gridlock on Democrats during the election. Total nationwide chaos with the corresponding rise in crime and damage to the economy....that's the Republican plan for victory. True patriots. 🤦‍♂️

Better donate to the Trump Twitter lawsuit quick before they manage to destroy your investment portfolio with the planned chaos...Trump can't sue social media without your cash donations because he's really a billionaire so he needs your cash...pay no attention to his standard microscopic fine print explaining that he may, at his discretion, use your donation for personal debts. Doesn't matter, DONATE NOW. He needs your money....to fight the invisible fight against those paper tigers and windmills. Please don't remember when he did the exact same thing begging for money to fight for the "election fraud" fraud in court but then pocketed the money and fired his (now disgraced and disbarred) lawyers without filing a legitimate lawsuit.

Netflix Series "Dark" Trailer

I didn't pick up any German words.

There's plenty to keep track of in this series: many characters and their interactions, many plots and subplots, many jumps between years, etc. YouTube is full of supplemental videos for details possibly missed by viewers.

Not today motherfucker

StukaFox says...

I'm pretty sure the dude's just having a good time because he's at a concert and he's all young and shit. He's probably high, too. Look at that glorious blue sky! Who wouldn't be joyous on such a perfect day when they're all young and high and shit? Dude, I'm old, it's dark and I'm not even at a concert (full disclosure: I am listening to Lord Huron's new album and it's fucking amazing. There's some stuff that's not up to their other work, and a weird 14-minute filler piece at the end, but Drops In The Lake might become the most beloved Lord Huron song ever) and I'm totally joyous right now. I'm also stoned out of my mind, so take that as a plus, a minus or a none-of-the-above. Look, all I'm saying is there's a cute video video of a sheep standing down a Border Collie. Props to the sheep for having the kinda balls it doesn't have anymore, but fucking with a Border Collie is asking for that dog to fuck up your tax return later. So yeah, y'know, cute dog and cute sheep and some Welshman who knows he's getting some pussy tonight and if that dog screws this up, it ain't gonna be the sheep getting fucked. That's life in Wales, man. Those dudes will fuck anything. I mean, if I was stuck in Wales with nothing else to do, I'd be looked at our four-legged friends in a far more than friendly way, too. Also, they don't have vowel mines there so they're stuck spelling words with all contestants and chunks of coal for punctuation. NO idea how that little linguistic hiccup got passed the Proto-Germanic language tree, but people in Quebec speak a language that's completely similar to French, only without the word order, the grammar and any words that are actually in French. The French hate that shit because they're French and no one in Europe is being all shirty these day. Except that dude in Belarus who apparently doens't know what an utter fucking legend the guy who runs Ryanair is. Fucking hell this shit's good. Anyway, the whole point of this was that a dog, a sheep and a Welshman walk into a bar and the bartender asks the man what he wants. And the Welshman tells, in exceedingly graphic detail, what he wants while the sheep and the collie listen in horror, straining against their leads and praying Pop-Up Darwin will suddenly appear and gift them opposable thumbs, a cellphone, and a SIM card that actually works in fucking Wales, because those vowel-less cocksuckers have a totally different cell system than the rest of the UK. Shit, you try to make a call to anywhere in Gwfjhsrmflsslll, the first thing you notice is that numbers have apparently joined the vowels in being MIA, and you're trying to explain that you just want to make a call to London and the operator is speaking some language that'd scare the shit outta C'htulu and finally you just give up and hop back on the Ryanair flight to JFK while scanning constantly for Mig-29s.

Anyway, be happy.
