No, the error is that I wrote "gallons" on the second line when I meant to write "pounds." It is a million pounds of water to make 28 pounds of fuel. That still means 125,000 gallons of water to get enough carbon for less than one minute of flight. A one hour flight would take over 7.5 million gallons of seawater to be processed. 7.5 million gallons that has to go through a chemical/screen/electrolysis method to extract that CO2 even before doing the Fischer-Tropsch synthesis.

A one hour flight would take over 7.5 million gallons of seawater to be processed. 7.5 million gallons that has to go through a chemical/screen/electrolysis method to extract that CO2 even before doing the Fischer-Tropsch synthesis.

That makes no sense: you had already stated that "So, a million pounds of water would have 337 pounds of CO2, and thus about 112 lbs of carbon." Why would 112 lbs of carbon result in only 28 pounds of fuel when all the carbon is turned into hydrocarbon fuel? The hydrogen atoms attaching to the carbon chain are not antigravity devices. 112lbs of carbon should result in more than 130lbs of hydrocarbon fuel (hydrocarbon chains usually have 2 hydrogen atoms for each carbon atom in the chain, plus two more hydrogens at the head and tail; assigning atomic weight 12 and 1, so (112/12) * (12+1+1) = 130.67; that's before adding the weight of the hydrogen atoms at the head and tail of the chains). A million gallons of sea water should result in over 1000lbs of hydrocarbon fuel if all the CO2 is taken out and the carbon in the CO2 molecules turned into hydrocarbon fuel, assuming roughly 337ppm CO2 concentration in sea water.

Edit: also the CO2 concentration number provided by Headset is wrong. Atmospheric CO2 concentration is usually cited as 412ppm in 2020. Sea water in 2021 is assessed at around 2050 micromol CO2 per kg of sea water (Molar mass of CO2 is 44). The latter translates to close to 900ppm by weight. So we should be looking at enough carbon in a million gallon of sea water to make about 3000lbs of liquid hydrocarbon fuel.

Reality says

Why would 112 lbs of carbon result in only 28 pounds of fuel when all the carbon is turned into hydrocarbon fuel?

Because JP5 weighs 6.4 pounds per gallon and it is about 2/3 carbon. Therefore, I divided 112 by 4 to get 28 pounds of fuel. But you are correct - the 28 lbs is just the carbon component, I should have added in the hydrogen part.

Reality says

Edit: also the CO2 concentration number provided by Headset is wrong

I had sources that averaged about 337 ppm, and here is one that I did not consider:



I thought .00205 moles/kg sounded high, so I compared it to the CO2 in Coke. Since Coke turned out to be about .14 moles/kg, your estimate is well within reason.

Gotta admit, I made a couple of unforced errors here, and Patnet has too many knowledgeable folks like you to get away with such goofs.

So, according to your inputs and calculations, 1 million gallons of water makes 3,000 lbs of fuel. My estimate of 28 pounds of fuel lasting about one minute would be true for a something like a Learjet flight, an Navy fighter in an operational mission would use that 3,000 lbs in about 30 minutes. So, the question is the feasibility an extraction process that needs 2 million gallons of sea water per hour of flight time, in addition to the process that creates the fuel from that extracted CO2. Interesting to see if the Navy actually does this.

What synthetic fuel would this be? Hydrogen? It has very high energy density in terms of kg/watt but compression of it to transport it makes it very inefficient.

Synthetic fuel as in produced by the Fischer-Tropsch process . . . i.e. both jet fuel (what the USN is after) and every kind of fuel and lubricant that Germany produced during WWII and their modern day equivalents.

I did not know that. I knew the Germans were making gasoline from coal but I didn't realize the were starting from carbon monoxide. I would bet even low grade high sulfur coal could be used to make synthetic fuel this way.

They eventually figured out the soils didn't suddenly become depleted of nutrients, acid rain from uncontrolled nitrous oxide and sulfide emissions lowered the pH of their local environment to the point where the still-plentiful elements couldn't get absorbed by the plant. Fortunately, the general danger had already been recognized and mitigation efforts started upon in the form of industrial and vehicle emission controls, so the multi-faceted problem of "acid rain" was already well on the road to being solved WITHOUT depriving humanity of the fruits of industry or mechanized transportation as critics of "the left" often claim.

The disappearance of the Acid Rain Scam, explained:

The situation turned out to be much more complex than had been predicted. The acidity of a lake is determined as much by the acidity of the local soil and vegetation as it is by acid rain. Many lakes in north-eastern America, dead in the 1980s, had plenty of fish in 1900. It was surmised by environmentalists that 20th-century sulphur dioxide emissions had choked these lakes to death with acid rain. But the NAPAP showed many of these lakes were acidic and fishless even before European settlement in America. Fish survived better in these lakes around 1900 because of extensive slash and burn logging in the area. The soil became more alkaline as the acid vegetation was removed, reducing the acid flowing into the lakes and making the water hospitable to fish. Logging stopped in 1915, acid soils and vegetation returned and the lakes became acidic again. The study also found that in many cases forests were suffering debilitation due to insects or drought and not acid rain.

The NAPAP reported in 1990. The findings were explosive: first, acid rain had not injured forests or crops in US or Canada; second, acid rain had no observable effect on human health; third, only a small number of lakes had been acidified by acid rain and these could be rehabilitated by adding lime to the water. In summary, acid rain was a nuisance, not a catastrophe.

SO2 cap and trade was immensely profitable; Enron wanted to expand it to CO2 and both protect their Nat Gas Pipeline investment and profit like it did from SO2 cap-and-trade bullshit:

Boreal Pines emit NO2 and contribute to smog and acidification of high altitude/latitudinal water bodies.
https://www.abc.net.au/science/articles/2003/03/13/804613.htm

Sensing profit through the ability to create panic and get the government to regulate competitors, the NAPAP release just made Corporations seek out new BS to amplify. After Acid Rain, the media pivoted straight to the Ozone Layer, another issue which was "disappeared".

Even though we now know that CHY-na is violating the CFC Treaty, and I very much doubt Chinese factories are limiting their SO2 emissions either, but not a peep.
https://theconversation.com/how-we-traced-mystery-emissions-of-cfcs-back-to-eastern-china-117545



Additional lines of investigation confirm NE China is source for burst of CFC Production; well in excess of Montreal Agreement amounts.
http://hydrocarbons21.com/articles/9010/study_confirms_source_of_cfc_11_is_northeastern_china

Because CHY-na is above criticism, it's too much of a supplier for Amazon and Walmart and for Wokeness in US Academia and NGOs... and cushy consulting jobs and good words with Chinese Universities and US NGOs for Revolving Door Bureaucrats to stand up against.

Totally politicized for profit and Narrative Construction purposes.

I'm talking about acidity of rainwater, which affects the microclimate of individual plants collectively but won't significantly change the long term pH of bodies of water due to dilution and buffering. Acid rain researchers and activists never claimed that acid rain was affecting the pH of bodies of water, that is a red herring dismissal of the entire topic. Sounds like you're just mashing up different claims, situations, and concerns as if they're one and the same.

I do not do "gotchas" here. I like the intellectual discussions with a knowledgeable crowd that includes various subjects and interests.

If your discourse was consistently as you claimed, you would have responded to the content of my original claim and rebuttal to you, not the form of it. Nobody is claiming higher atmospheric CO2 levels will NOT increase plant growth in the absence of other localized nutrient constraints, and to my knowledge this has claim NEVER been made in any discussion or prediction of the effects of rising atmospheric CO2 concentration.

Oh, I've heard this. The forests were burning down last year on the West Coast because of global warming and large areas of the Earth was going to return to desert. Famines were going to happen as a result of global warming, I've been hearing that since I was a kid.

I spent a few minutes the other day trying to get images of what South America looked like over the years, but I gave up. If http://maps.google.com is accurate (?) the amount of jungle in South America is in 2007 is identical to what it is today.

I've heard so much BS about global warming, so many lies, how can I believe anything they say at all? The arctic was actually reported as being ice free one year. They actually printed that in national papers. It was completely false.

The purpose of the Acid Rain panic was to privilege Nat Gas over Coal. There was never any Precipitation driven acidification of mountain water, which was the metric by which they measured acid rain to begin with and how it got to be a concern in the first place; that acid rain in isolated mountain water bodies were killing fish.

Instead, it was the soil chemistry caused by protecting mountain lake areas "Area of Natural Beauty" from harvesting.

Geological evidence confirmed that Pre-European (much less pre-industrial) mountain lakes in North America were more acidic with smaller fish populations than today.

Yeah, well I've been hearing skeptics take a gunny sack of completely independent claims about climate change, mash them together in nonsense ways, and conclude that "climate change is fake and proponents crazy/stupid" for decades. I expected much better than that from you in this thread.

Man, if there's on phrase that is total bullshit

"The Science says..."

or the alternative version:

"not according to the Science."

There is no such thing as "The Science". Science is a process, that depends on Free Debate, Falsification, Criticism, and repeated observations and testing.

100 years ago, if today's standards applied, you'd be told it was "The Science" that Continental Drift/Plate Tectonics were just Human Beings seeing Patterns in Nature as usual, just like People can see Mickey Mouse in a Cloud. Although the fossil record and geological strata fit beautifully with the theory.

15 years ago I'd be in complete agreement with you. Seriously.

I remember thinking "they can't be possibly lying about this, because if they are, they have entirely destroyed their credibility and will have a full track record of themselves being wrong repeatedly. They can't be that stupid!"

* They did this with weapons of mass destruction in Iraq. I actually expected the US to plant MOBILE weapons labs, after all that's why they were claiming they were MOBILE, that's easy to fake..
* They did this with "Qaddafi was about to cause a humanitarian crisis" in Libya.
* They did this with Climate Change.

After all, a huge well founded organizations couldn't be so reckless could they? But they have been.

I remember LAUGHING and denigrating people that questioned the climate change story. They didn't understand science, they would bring up stories like Egyptians thought their arrows being shot through the air effected the weather, and other nonsense - comparing those primitive civilizations to ours and probably wasn't even true. Religious charlatans like televangelists railed against it. Well, if those MORONS were on that side, and a bunch of scientists were on the other, who should I trust? I can't evaluate the data. I have to have some faith, and here's all these REALLY SPECIFIC predictions that if they get wrong will completely ruin their credibility if not CAREERS.

All the predictions were wrong. ALL of them.

You might complain that "the science about covid has been politicized" - well climate change sure as hell has been, at least 30 years ago.

I know it's hard to believe, but the dummies, the religious nuts, the fundies, the people that just think scientists have no clue what they are talking about - were right. Do you think I came to this conclusion easily? I used to argue with my parents about this, I couldn't believe how STUPID they were. A few years ago I was talking to them and admitted I was wrong - and their response was "you really believed that crap??" They had no clue I was being serious from previous conversations. They thought I considered it a possibility, not an absolute - and being the fucking nice assholes they are, they didn't pushback. I hate it when people do that shit. If you think I'm wrong, do me a favor and point it out, but if you're wrong, I'll reciprocate. For 20 years I believed the nonsense.

For almost half a century, we've been routinely promised global warming that will "result in Manhattan being THREE FEET under water by the end of the (90s, 00s, 10s, now 20s) if we don't take action now.

In the 70s, Brown Geologists wrote to the President demanding action on the coming Ice Age, expected to come within the next 40-50 years.

Some suggested Nixon not wait a moment, but load up 100s of C-130s with soot and ash byproducts of coal burning and industry, and spread them over the poles ASAP to lower the albedo of the Earth. As usual, it was Action Now! There is no Time to Lose Before the Crisis Hits! No more research, just DO IT NOW!

Thank goodness they were ignored, but contrary to AGW alarmist websites, talk of avoiding an ice age were routine items in Media in the 1960s and especially 1970s. It's consistently gaslighted away, even though it made covers of widely read weekly magazines and even the subject of entire network TV documentaries.

Except now we hear wide ranging plans, but along the opposite lines. Yet the very wealthy continue to buy oceanside property and banks are still writing mortgages on them and insurers still insuring those properties.

One reason I'm convinced it's all actors looking to manipulate markets - like SO2 and the proposed CO2 cap-and-trade desired by Enron - is that Nuclear Power is entirely off the table, and "The Science(tm)" keeps the general population ignorant about Nuclear Power not being limited to high pressure Steam-Powered Fast Reactors.

Much of the AGW is a game to facilitate third world outsourcing while kicking the ladder down in first world countries by imposing enviro laws; and a battle between Fossil Fuels.

I have what ought to be a pretty easy task for you.

Find a prediction made in a journal or a newspaper about the effects of "climate change" that turned out to be correct. If you say "hurricanes", I'll stop you. We see a lot more hurricanes since the late 1960's, because we have satellites - the number that hit landfall hasn't changed.
