Chrysler Hemi FirePower Engine Rebuild Time Lapse

newtboy says...

Nice.
I wish they paid more attention to the combustion chamber. Most people don't know what a hemi is beyond a powerful motor. The hemispherical combustion chamber produces far more power than a normally shaped one. Even partial hemispherical combustion chambers (semi-hemi) can seriously increase the power of most motors....but also decreases the fuel efficiency.
I use a semi-hemi cut 1776 VW motor in my race buggy, and it outperforms much larger motors.

Avatar Style Mech

SFOGuy says...

Yup; here is the Live Science take---in brief--it's a conceptual artist's thing (Vitaly Bulgarov) who has faked a website and even the Korea development company...

"New video clips purporting to show a 13-foot-tall (4 meters) humanoid robot piloted by a person in its torso look like something straight out of "Avatar" or "Transformers," but a Live Science investigation has revealed reasons to believe some skepticism might be in order.

The robot clips have been picked up by a variety of online news and technology outlets, including Kotaku and Wired UK. But the South Korean company that is supposedly developing the robot has virtually no online presence and was unfamiliar to robotics researchers contacted by Live Science.

Furthermore, the only source for the videos or any information about them is the Facebook and Instagram pages of a designer whose website mentions a conceptual art project about a "fictional robotics corporation that develops its products in a not-so-distant future."

The designer, Vitaly Bulgarov, told Live Science that the robot is real. However, he declined to share the names of scientists or engineers working on the project, and messages to the purported CEO of the company went unreturned. [Gallery: See Images of the Giant Humanoid Robot]

Mystery business

According to Bulgarov's Facebook page, the videos were taken in South Korea at a company called Korea Future Technology. Almost all references to this company online appear to be associated with Bulgarov's posts and the subsequent news pieces on the robot. Bulgarov said the company has been operating for several years."

""Robots are messy business," said Christian Hubicki, a postdoctoral robotics researcher at Georgia Tech who worked on the DURUS robot. "They get torn apart and put back together over and over, and transmission grease gets all over the place. Even the nice white floor is beautifully unscuffed [in these videos]. Never once during likely hundreds of hours of debugging the giant robot did it kick in a way that scratched it up?"

The people around the robot also appear to be too close for safety and are not following the standard practice of wearing safety goggles, Hubicki said.

Bulgarov said the company's CEO required that the lab be clean, and that the videos had been brightened in postproduction. Fearing said robotics labs in Asia can be relatively neat.

However, there's another problem: Hubicki told Live Science that the robot's leg joints look unusually smooth given the force that the step of a 1.5-ton robot would exert on the motors. [5 Reasons to Fear Robots]"

Detroit Lt. Arrested For DUI

This isn't the first time and the dude blew a .28 after the ride to the station and going through booking. That isn't a typo, literally over 1/4 of the blood in his body was actually alcohol. Death from alcohol poisoning can occur at .37 or higher.

The scary thing is that his tolerance must be massive, because he was still somewhat capable of speech and movement. Usually .25 to .30 level drinkers display general inertia, near total loss of motor functions, little response to stimuli, inability to stand or walk, vomiting, and incontinence.

Freevalve Camless Engine

robbersdog49 says...

They're using port injection, so without the engine turning there's nothing to pull the fuel into the cylinder.

I love all this technology though, I'm a real petrol head but I really do think this is the dying throws of the internal combustion engine. Electric motors just have so many advantages and the disadvantages are disappearing fast.

Payback said:

I've heard camless engines don't need starters. They just squirt a bit of fuel into a combustion-cycle (down stroke) cylinder and fire the plug.

Working Miniature V8 Paper Engine

Sagemind says...

I think my point was missed here.
It is impressive - no argument there.
But it's not an engine, and couldn't run anything. It's powered by an outside source. It doesn't create energy, it's the recipient of energy. I suppose if you want to credit it as a motor, you could credit it the same as an electronic motor, which uses outside energy, but not as a V8 engine which generates it's own energy.

Youngest Female Monster Truck Driver Builds Her Own Rides

newtboy says...

It depends on how you do it. If you reconfigure the motor/trans so it sits lower overall, but the bottom is the original height, then no. Moving as much weight to the bottom of the frame as possible without lowering the frame itself was always the plan with my race buggy. That said, it does seem like her suspension is Set lower than normal, so she's more prone to high centering, but clearance is usually measured at the axles (except in vehicles with geared hubs that raise the axle above the tub).

ChaosEngine said:

......
I get lowering the centre of gravity, but wouldn't that also affect the clearance?

RetroReport - Nuclear Winter

Buttle says...

Most of the population of the world is still impoverished by a lack of access to electric power, motor transport, manufactured goods, chemical fertilizers ... Stuff you undoubtedly take for granted. Climate change is a gigantic distraction and a power grab, and focusing on it will result in many poor people remaining poor.

There are real problems to deal with, for one, fossil fuels really are present only in limited supply, and we'll have to somehow stop using them eventually. Climate hysteria does not help.

What is the worst case scenario if climate change isn't real?

I can't really think of anything significant.

Bill Burr - Buzz Aldrin Punches Guy

Talking to a conspiracy theorist about either the moon landing or the flat earth theory is exasperating. They discredit a scientific theory on the slightest technicality in your brief retelling of it, but if you baulk at their vague one-sentence alternative you're brainwashed.

You can tell them about the retroreflectors, or the satellite images we have of the landing site. You can tell them about sundials, the phases of the moon or constellations.

They don't care - anything can be faked and their definition of "proof" boils down to seeing it with their own naked eye.

It's totally impractical to take everyone up in a Red Bull balloon to see the curvature of the Earth for themselves. Presumably you'd have to take everyone up twice at two locations to show that the circular horizon is not an edge. Or kill two birds with one stone and take them to the moon landing site and back again because nothing less will suffice.

Because if I take them to the most advanced telescope in the world and focus it on the moon landing site - the image could be faked. You could show them how the telescope works, but each component could produce a faked output. The only way they would accept the telescope information is if they built it themselves from raw materials - oh you used a standard electronic device such as a basic motor? Illuminati dude, that thing can produce EM waves that fake the image. You're going to use a Macbook to read the USB output? Are you a shill?

Literally nothing is good enough but they are all, without exception, too fucking lazy to go and prove it to themselves from first principles.

Which is called "getting a degree in physics", where you are also taught to question every step, AKA being "brainwashed".
