Safety analysis of natural gas vehicles transiting highway tunnel - June 1989

A safety analysis was performed to assess the relative hazard of compressed natural gas (CNG) fueled vehicles traveling on various tunnels and bridges in New York City. The study considered those hazards arising from the release of fuel from CNG vehicles ranging in size from a passenger sedan to a full size 53 passenger bus. The approach used was to compare the fuel hazard of CNG vehicles to the fuel hazard of gasoline vehicles. The risk was assessed by estimating the frequency of occurrence and the severity of the hazard. The methodology was a combination of analyzing accident data, performing a diffusion analysis of the gas released in the tunnel and determining the consequences of ignition. Diffusion analysis was performed using the TEMPEST code for various accident scenarios resulting in CNG release inside the Holland Tunnel. The study concluded that the overall hazard of CNG vehicles transiting a ventilated tunnel is less than the hazard from a comparable gasoline fueled vehicle. 134 refs., 23 figs., 24 tabs.

The thing with natural gas is it's *very* picky about stoichiometric ratio. Too much or too little air and nothing happens.

The danger with LNG is the cryotemps before the 'natural gas' and the danger with CNG is the compressed cylinder more than the natural gas. Both can easily be mitigated.

That's why you had to go to the Old Testament to get the barbaric bits.

The name escapes me but I swore there was a small group that wasn't kosher with that Jesus guy. (And the whole first testament as a result).

So does it still let you "always click to flash"?

It'd be a real pain in the ass if, by watching one video, I have to always allow Facebook (major example) to run flash content, rather than just the specific flash content I authorize.

Also: where's the "click to run HTML5 video", please?

Well, that's utter bullshit.

The very first link's very first sentence in the transcript:

"During the presidential campaign, Donald Trump suggested that he might favor creating a database for Muslims who enter the United States."

That's just adding religious affiliation to the already massive amount of information we collect about visitors entering the U.S., including their fingerprints and criminal records.

It's for visitors.

Slashdot editors: Please corrector your headline to add the word "Visitors" after the word "Muslim", and replace "Muslim-Americans" with "Muslim Visitors" in the first sentence of your summary.

It is their job, their purpose, to spread Islam and the Sharia law to every corner of the globe.

Exactly, as the Quran says:

“And he said to them, “Go into all the world and proclaim the gospel to the whole creation. Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.'” - Mark 16:15-16

“And this gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come.” - Matthew 24:14 NKJV

And what about those that are sinners?

Now therefore, kill every male among the little ones, and kill every woman who has known man intimately. But all the girls who have not known man intimately, spare for yourselves - Numbers 31:17-18

And let us not forget how the Quran deals with unruly children:

If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them: Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place; And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard. And all the men of his city shall stone him with stones, that he die. Deuteronomy 21:18-21

And what if someone mentions other faiths?

If your very own brother, or your son or daughter, or the wife you love, or your closest friend secretly entices you, saying, “Let us go and worship other gods” (gods that neither you nor your ancestors have known, 7 gods of the peoples around you, whether near or far, from one end of the land to the other), 8 do not yield to them or listen to them. Show them no pity. Do not spare them or shield them. 9 You must certainly put them to death. Your hand must be the first in putting them to death, and then the hands of all the people. 10 Stone them to death, because they tried to turn you away from the Lord your God, who brought you out of Egypt, out of the land of slavery. 11 Then all Israel will hear and be afraid, and no one among you will do such an evil thing again. - Deuteronomy 13

At least I swear that was the Quran, I always get my fairy tales mixed up.

Why in gawd's name would anyone mass produce such a device? This must be one of those fake news stories we've been hearing so much about.

I can't imagine any legitimate use for such a device, so I assume it would be made illegal as soon as the politicians can get off their duffs.

I'm sure certain companies and government agencies working with very sensitive information or critical infrastructure would find some value in it. You can disable USB in software or fill the ports with hot glue gun glue, but both can be undone/worked around. There may be other, better methods to secure the USB ports, but there are definitely some legitimate uses for such a device.

These guys have finally designed the world's best 2005 Semi Truck.

Also one or two full-size beds will be included inside the vehicle's enormous cab.

For who? Are they trying to milk the last owner operators? Walmart quibbles with OEMs over 0.1 MPG claims. The second they can, every single Walmart truck is going to be replaced by an autonomous driver, even if it's just between cities. (Given where most Walmarts are located it'll replace 90% of their need for drivers). They spent a lot of time and money designing something that will never get used by time this hits the market.

, the vehicle will provide nearly double the power of the current-gen diesel-powered semis/articulated lorries

And? Truck OEMs are moving to Natural Gas. Locomotives are too.

Everyone thought Warren Buffet was crazy buying a rail company in 2009. Turns out that he owns Northern Natural Gas the largest interstate natural gas pipeline system in the United States. Northern Natural Gas' pipeline system stretches across 11 states, from Southern Texas to Michigan's Upper Peninsula, providing access to five of the major natural gas supply regions in North America. (At which point he starts to sound a bit more like Rockefeller).

10 years ago Natural Gas was a 3rd party add on. Now the engine OEMs are selling it in addition to dual fuel engines (NG/Diesel). That goes for engines for a small tractor up through their largest stationary engines.

Natural gas is:

  1. Domestic.
  2. Cheap
  3. Run to households in a lot of the US.

With a tiny compressor you could come home and 'fill up' at night..

If I was an investor the 2 power sources for vehicles going forward are going to be natural gas & batteries. You cut out a lot of gasoline and diesel refineries. You can run locomotives and semis on natural gas (since batteries alone can't (yet)).

Hydrogen, in 2016, is a non-starter. First you can't just 'get' it. We're quickly getting an EV grid and the Natural Gas 'grid' is already there.

Finally it's not about horsepower. Those Semi truck engines "only" pushing a few hundred HP can easily put out more. The Caterpillar D11 bulldozer only has 850 HP. The reason they're de-tuned is they're designed to do that 24 hours a day, 7 days a week for a million miles. You can easy tune them up to easily out do the 1,000 horsepower and 2,000 foot-pounds. [And why geeks that aren't into machinery shouldn't just look at specs like they're computers.]

By 2020 this is going to look like a dinosaur.

No, what you're saying is that people with no expertise in a field feel that they have an ability to critique a rather specialized field they have no expertise in.

It's a fallacious appeal to authority, full stop.

You are claiming authority without evidence when you argue, but when they argue under the same circumstances, you claim fallacy.

You are engaging in a variant of the false equivalence fallacy called the false inequivallence fallacy.

You right, because you're right, and they're wrong, because they disagree with you, even though you are not an acknowledged expert, nor are you citing sources who are acknowledged experts. Full stop.
