Bd6r saysSo optical activity of deeper oil deposits is lower than that of more shallow deposits? Link please with values of optical rotation for both
Not talking about comparing different well depth from different areas. The deep drilling / cracking in the last couple decades has been below the zones of old "depleted" oil wells and coal mine areas, and they have been coming with natural gas, with little optical activity to speak of.
well ICE engine management keeps breaking through points of diminishing returns of earlier generations, but it's hard to see much improvement from where we are now. Thanks largely to cheap MOSFETS and the energy density breakthrough of lithium, electric vehicles are very competitive now with ICE vehicles. Converting the entire fleet to electric faces constraints in the delivery grid and lithium supply.
The difference wasn't meaningless, it was "worth it" enough to purchase a years supply of different fasteners and tooling, and by 1mm steps to previously "odd" sizes, not 2 mm steps to the next "standard" tool head size. The design and development departments at this time were working with world suppliers like Bosch, Nippondenso, and Aisin-Warner 6-8 model years ahead of the one in question, so basically production matters like the fasteners don't affect the design team in a zero sum game in enterprises of this scale.
the fastner size therefore strength reduction might make the vehicle less safe
Do you know what compounds are present in nat gas and how many of them can be optically active?
Nope, they used similarly sized fasteners with not loss of performance on future models, the originals were overkill if anything.
Patrick says@CaptainHorsePaste That's interesting. So what's the answer?

Imagine you are eyewitness to an important event. You know exactly what happened. But then someone down the line tells a different story. This fake account by someone who did not witness it becomes the prevailing theory on what happened. So you take out your diary where you have recorded what actually happened and start to share it with anyone who will listen.
richwicks saysAutoman - you can't do this to make an argument. You're appealing to a faith that isn't shared by everybody.
it's his thread.
You can proselytize your views and correct people for their reasoning and tell them why they are wrong on your own thread.
My critique of the American auto industry is that they really DID spend money on lawyers and lobbyists and PR, INSTEAD of engineers. The Japanese in particular quietly went about meeting and exceeding the requirements, and ate the American carmakers' lunch starting in the 80s as a result.
All you fuckers are either really smart or the best bull shitter's I've ever run across.
Bd6r saysDo you know what compounds are present in nat gas and how many of them can be optically active?
Likely no optical activity whatsoever, like I said "with little optical activity to speak of." IIRC, so-called "optical activity" happens/happened only to petroleum components/distillants greater than 220 molecular mass, that's equivalent to having more than 15 carbons in a chain or ring; peaking around 400 molecular mass, i.e. equivalent to nearly 30-carbon in a chain or ring. That's some heavy lubrication oil / ship bunk fuel territory before hitting wax territory around 40-50 carbon. Natural gas is mostly 1-carbon Methane, with some smaller fractions of 2-4 carbon chains, far shorter than the 15-carbon jet-fuel range, where "optical activity" started to show.
If I may speculate a little here: IMHO, that focus on "optical activity" was a little fraud like today's PCR (magnificat...
you didn't witness. You're just repeating a story

That story was written by the eyewitness. It is his diary.
Origins of petroleum: Biotic or abiotic? Biden's farts.
Anyhow, you didn't witness. You're just repeating a story.richwicks says
I wouldn't start a thread just to criticize somebody's reasoning. I'm just tellingrichwicks says

I remember those times. In 1980's, a "rice burner" didn't even come close to meeting American safety standards but American car makers had to meet those standards.
Are any of my statements incorrect?
Also, they absolutely DID have to meet minimum motor vehicle safety standards to be able to sell in the North America market.
except the Pinto.
They denied it was a problem for as long as they could
History is rhyming.
richwicks saysexcept the Pinto.
The Pinto was actually a VERY good car in many ways.
then did a recall that consisted of inserting a plastic shield between the tank and its mounting straps by the differential it would puncture upon.
Yes, in these cases owing to the underlying fact that laissez-faire capitalism routinely and ruthlessly places personal, shareholder, and company profit above public and individual client health, safety, and value.
It's one thing to discuss the topic Automan asked, biotic or abiotic? That's a fun topic for discussion. Quite another to use his question to point out the Intellectual Inferiority in others.

Whereas socialism excels in unpersoning and killing huge numbers
People's selfishness is not the result of laissez-faire government policy or capitalism.
Capitalism with an overlay of some "socialist" regulations and standards brought us cars producing low pollution and high fuel economy while still offering great performance.
Guys, that wasn't an anti-Capitalism position, and certainly not a recommendation to switch to socialism instead. I love Capitalism the way Churchill loved Democracy. It's a flawed system that sucks in these particular ways, but it's still way better than all of the alternatives. Capitalism with an overlay of some "socialist" regulations and standards brought us cars producing low pollution and high fuel economy while still offering great performance. A win win for big industries, consumers, and conservationists. A famous comparison before the Berlin Wall fell, Soviet industries like steelmaking tended to use 5X the energy as Western industries did to convert raw materials to the same amount of finished product.

WRT to the abiotic origin for hydrocarbons, what we've found on Titan to me strongly suggests that hydrocarbons may very well have been part of the formation of the planets.
After several billion years it seems unlikely most primordial gaseous hydrogen would have long since outgassed or bonded with non-mobile elements including what may become abiotic petroleum.
From what I was just reading (having just boned up more than ever on the topic of abiogenic oil for sake of this discussion), there EXIST deposits that are considered abiotic in origin by both geologists and oil companies, but only a few of them are commercially exploitable and small/limited at that. All the large pools of oil, whose availability and cost of extraction and delivery is a huge mover in the world economy, are considered mostly biotic in origin, with a minor abiotic contribution possible in some formations.
Relevant to the usual context of abiotic versus biotic origins of oil, if primordial hydrogen is a big constituent of abiotic oil production, it's a finite, limited, closed system resource. People usually cite abiotic oil as part of anti-conservation sentiments, as in "Oil's made by the earth and endlessly renews itself! Therefore, conserving it is pointless and stupid"
What they call signs for biogenic are actually signs for bio-contamination of what came up from below.

The abiotic case is that carbonate rocks and water get subducted by plate tectonics and changed by the deep heat and pressure into petroleum spectrum molecules.
This is often brought up by people holding cornucopian pro-petroleum positions, suggesting that because it's an abiotic process, oil is endlessly renewable. Proponents never take the hypothesis further and detail processes, timelines, and specific deposits showing clear evidence of abiotic origin. Furthermore, they never seem to recognize that even if petrogenesis proves 100% abiotic and as described, it's STILL too slow of a process to provide limitless energy resources to humans for limitless time.
The biotic case is that extant petroleum deposits consist of metamorphosed ancient biological deposits like algal mats in lakes. Much of the coal on earth was originally jungle land that existed before cellulose eating bacteria evolved, resulting in very long term in-situ accumulation of carbon.
Accessible oil shale deposits contain identifiable fossils and chemical signatures of biological processes. A particularly good example is the Messel Pit in Germany, an ancient lake which formed in a deep volcanic vent with chronically low oxygen below the surface waters. The pit was believed to release intermittent clouds of CO2 that caused mass die-offs of larger animals, whose bodies sank to the hypoxic depths to become preserved in remarkably excellent condition. The contents of this pit were estimated to represent over a million years of accumulation, from a time period approximately 47 million years ago. Therefore, this pit is not only proof that oil CAN form biotically, it gives a lower bound of 47 million years needed for that to become oil under those specific conditions since. The location is believed over time to have drifted 10 degrees further North in latitude in addition to gaining up to a few hundred feet of overburden above the shale deposits. https://www.age-of-the-sage.org/evolution/messel_pit.html
Proponents of abiotic petrogenesis, are you aware of any specific oil deposits that can be conclusively proven to have formed only by abiotic processes?
