LOL you noob you just forgot to tune the spangles on a pallet of tanks pre Inglebertization.


True i'm not sure how i overlooked something so obvious.

Don't you just hate it when videos like this gloss over the details.


Remember to oxidate your galvanized x432 scuba cylinder not before but after the hotplate tempering Inglebert process.

shit happens.. I am going to get a hot dog.


hope you seen my videos in my que with the 18 cylinder tractor.

GAWD DAMN THAT SOUNDS LOVELY ! ! !!


brawwwwwwwwwww brawwwwwwwwwwwwwwwwwwwwww brawwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww

*edit, you did GOOD FOR YOU. that sound so wicked. VR000M VR0000M VR00000M. I want one of those engines in my pt cruiser.

What new channel would you like to see? (User Poll by Throbbin)

kronosposeidon says...

@Throbbin: These are all rocket-testing videos:

http://videosift.com/video/Plasma-Rocket-Testing
http://videosift.com/video/Ares-Rocket-Test-Fire-At-Corrine-Utah-9-10-09
http://videosift.com/video/Nasa-methane-gas-engine-test
http://videosift.com/search?q=rocket+test

That's mega-combustion in all cases. Would they fit, yes or no? And like I said, cars have internal combustion engines. There are mini-explosions genuinely taking place inside of each cylinder in them. Now you might think it wouldn't come up, but I guarantee you, sooner or later it would. Like in the case of this video:

http://videosift.com/video/Actual-footage-from-inside-a-4-stroke-engine-Wow-cool

So if that were added, then one might legitimately claim that anything involving engines would be kosher for the Combustion channel. So it's not as common-sense as you might think.

Look, people sometimes debate shit about what belongs in all of these channels:

Femme
Lies
Terrible
Viral
Sexuality
Eia

And others. So is it so terrible to ask for clarification, or to even suggest that maybe a combustion channel might be too broad?

And the last part of my comment is tongue-in-cheek, esse. It was meant to show that I'm not being overly serious about anything. I trust that most sifters would understand that - you may not.

Wikileaks - U.S. Apache killing civilians in Baghdad

NordlichReiter says...

I've never seen a RPG with a telephoto lens before this video. Hell, I've never seen a rifle swing like a camera does on a sling either. When they said he had an AK-47, I thought, "Well that's a fucked up looking AK-47, why is it swinging like that next to his hip? Fucking thing must be bore heavy." The point is, the fucking camera was swinging at an axis with the strap it was connected to, simple laws of physics. A rifle has a stock, well most of the AK47s I've seen, and is not bore heavy.

What I saw was escalation based on assumption. You know what they say about assumptions? They make an ass out of you and me, and in some cases they kill people.

Now, I empathize with the pilot, and gunner at 4:01 in the video. One of the guys appears to be carrying a long object of the cylinder variety. If the video is any indication of what the gunner is seeing then how is he to know that the cylinder isn't a camera tripod?

I've watched this video multiple times, and I have to say given the right primer a person can imagine that they saw an AK-47.

One person's fear, stink, or demeanor can cause a whole shit storm. For instance humans can smell the fear stench of anotherContagious gunfire?

Millions of dollars spent on this technology and a simple problem like contagious gunfire can't be solved. It can't be solved because it is a sociologically evolved symptom of contagious fear, fear is beneficial to genetic survival. That's my observation anyway.

Detach yourself from emotions, think critically and with the mindset that all people are innocent until proven otherwise. That is the only way to minimize innocent death, or capture. That's called a black-list, meaning that something has to be explicitly denied given a certain body of evidence. Conversely a white-list give special privileged to only those that are safe and supported by a body of evidence. Given that the real world is not electronics a white list is not possible, because it philosophy, and inherently denies every one until otherwise. That does not engender itself to support from the masses.

I honestly cannot say that I saw weapons in that footage, because I cannot trust my eyes.
For this I cite the Mind Hacks by Tom Stafford and Matt Webb. Specifically Chapters 2 and 3.

Michio Kaku discusses the Science of Mass Effect 2

Raigen says...

That was always the biggest question I had when I heard about this "cylinder" of light bending around an object. Yes, if you bent light around you, so that it recombined on the other side, you would in effect be totally blind because no light was reaching your eyes.

Michio Kaku described this as a problem in a video I saw here on the Sift a while back, and he said so far you'd basically have to cut two eye holes in the cylinder, but then there would just be two eyes floating around the room.

How To Handle Unintended Acceleration

supersparky says...

The Prius that was in the news recently, here in San Diego, the conventional brakes were useless, and shifting to neutral wouldn't work, as it wouldn't allow it. What was successful, according to the CHP, was a very zealous tug on the hand brake (definitely an "emergency" brake in this case) as well as the foot pedal. The officer positioned his car in front, not to slow it down, but to prevent it from shooting forward after the driver finally got the car to a stop, despite it still wanting to move forward. Essentially the squad car was acting as a brick wall, but not a brake assist.

In this case, the car would not shift into neutral, nor did foot braking alone make a difference. It was muscle on the hand brake that ever so slowly dropped the speed.

You are correct about the first casualty. It was a Lexus and it happened in Santee, CA (part of San Diego County). The brake and neutral attempt were useless. The situation is described thus:

---
California Highway Patrol Officer Mark Saylor, 45, his wife, Cleofe, 45, their daughter Mahala, 13, and Cleofe's brother Chris Lastrella, 39, were traveling on a freeway near Santee on Aug. 28 when their vehicle reached speeds of more than 120 mph, hit a sport utility vehicle, launched off an embankment, rolled several times and burst into flames.

Investigators found that a wrong-sized floor mat that trapped the accelerator was the cause of the crash. (Note, this has not been forensically proven, and is in dispute at the moment.)

A haunting 911 call captured Lastrella telling the others to pray before the car launched off the embankment.

...the Lexus ES350 "began to accelerate on its own." Saylor attempted to apply the brakes and do everything possible to stop the car, but he was unable to do so...
---

The video demonstrated the "technique" on a relatively low horse power (and low torque) four cylinder engine. A Lexus ES350 has a 272HP V6 (at full throttle) and the Prius has a high torque electric motor. Good luck with that braking.

What this article fails to include are the unique issues with the hybrid cars. Oddly enough, two have gone out of control in my home city, San Diego. The first being a death, which started the publicity. This one was driven by an off duty cop! I would think his training would have given him these skills to stop the car. However, as more and more facts have come out, the brakes it seems are useless. The Prius uses a combination of electrical and mechanical braking. Unfortunately the mechanical only kicks in under a certain speed.
Many people have reported burying the brake pedal to the floor and it having little effect. They also seem to not be able to shift into neutral, as it's a drive by wire system. Many cars don't let you shut off the engine if it's in gear too.
The Prius, while being a butt ugly eye sore and gutless wonder, also has an electric motor. These have 100% of their torque at any RPM. This means a gas engine can be fought and stalled with functional brakes, but you fight the full torgue of an electric motor all the way down to stopping, if you're lucky.
No, a fail-safe override needs to be considered for all drive by wire vehicles. Something that actually physically disconnects power from the system as a last resort.

My understanding is that the car driven by the off duty officer was a 2009 Lexus ES 350. That is not a hybrid. That said, I tried the 'move the shift to neutral' trick yesterday in my Windstar and it worked just fine.
However, the link I provided also noted: Last month, Consumer Reports found that models that don't have so-called smart-throttle technology, which allows the brake to take precedence over the throttle, a vehicle might not have adequate brakes to overcome a stuck throttle at 60 mph.
So, jam your foot down on the brake and kick it into neutral, pray like hell that you hit a truckload of Snuggies.
As for the electric cars, maybe a nuclear air burst that issues an effective electromagnetic pulse would do the trick.

Liquid Fluoride Thorium Reactor - Google Tech Talk Remix

curiousity says...

Here's a talk by Bill Gates about nuclear power as an energy source. Not about Thorium, but still interesting... I tried to sift it, but it kept giving me an "code is incorrect" and I just don't know enough to fix it:

Boing Boing article: http://www.boingboing.net/2010/02/12/highlights-from-ted-2.html
TED video: http://www.ted.com/talks/bill_gates.html?awesm=on.ted.com_89Dt

excerpt from article above:
"A molecule of uranium has a million times more energy than a molecule of coal." He and Nathan "Mosquito Zapper" Myrhvold are backing a nuclear approach. It's called Terrapower, and it's different from a standard nuclear reactor. Instead of burning the 1% of uranium-235 found in natural uranium, this reactor burns the other 99%, called uranium-238. You can use all the leftover waste from today's reactors as fuel. "In terms of fuel this really solves the problem." He showed a photo of depleted waste uranium in steel cylinders at the Paducah Gaseous Diffusion Plant in Kentucky -- the waste at this plant could supply the US energy needs for 200 years (woah!), and filtering seawater for uranium could supply energy for much longer than that.

@dag: I studied how fluids mix in a granular medium, ie in a glass cylinder filled with small plexiglass pebbles. When air is inserted into such a cylinder filled with a liquid, it creates beautiful finger-like structures if done in the absence of gravity.

Young Woman's Field Strip Demonstration-AK-47

radx says...

>> ^Napalm:
She actually uses the screwdriver and the butt (heh heh heh "butt") of the screwdriver several times.


Four times total: 1) on the gas cylinder release to remove it, 2) on the handgrip release (lever on that small ring she moves towards the front of the barrel) to remove it, 3) on the handgrip release to reattach it, 4) on the gas cylinder release to reattach it.

She had some problems getting the dust cover back on though, so it might be a slightly damaged weapon.

Young Woman's Field Strip Demonstration-AK-47

radx says...

>> ^Napalm:
Question for people with more assault rifle experience.
Is it normal to require tools to field strip a rifle? Would improvised tools work (rocks)?


No tools are needed to strip an AK47.

At 0:27-0:31, she uses a screwdriver to pull back on the gas cylinder release. It's a small lever that's a bitch to move on poorly maintained weapons, but becomes easy to use with age or proper maintenance. Same for the handgrip release she manhandles 0:37-0:42.

It's just those two levers that she couldn't pull without a tool.
