subway under the ocean |

Posted by JRR4 on Fri Jun 16 11:30:41 2023 Biden says he wants to build a railroad crossing across the ocean. I wonder if a subway makes more sense. |

If Russia had a more reasonable government, there would probably be good economics in a decently speedy freight and maybe even passenger railroad from Chicago to China and Europe via the Bering Strait. Probably a tunnel under the Strait. |

My father was a motorman on the Flushing line, and back in the 1950s and 60s, the workforce was overwhelmingly Irish and Irish-American. My dad used to call the Irish-born ones "Hibernians." We were at Main Street one day, probably to go shopping at Gertz, at the time when the TA was lengthening the station to accommodate longer trains. As we were going upstairs, my dad ran into one of his Hibernian co-workers. I asked him what they were building at the end of the station.The Hibernian said to me, "Why they're building a subway to Ireland!" I must have been maybe 7 or 8 years old and totally believed him. |

This is the sort of idea that is born strictly of ideology-- in other words, since jet fuel is bad, and electricity is good, therefore, an electric-powered railroad across the ocean must be a good idea, even if it is more or less impractical today. I can only imagine the cost-- and the cost overruns, not to mention the ongoing maintenance costs of such a venture. |

It's not that "jet fuel is bad" that is the key concern...it's that there's only so much oil to make it out of. One day that WILL run out. What are we going to do then? And it's that attitude so many people have of "Well, I won't be around when that happens" that only makes it worse, because it makes people not inclined to do anything, to leave it to the generations who will face the issue instead of fixing it NOW so we don't have to worry. There is a saying that gets bounded around and the wording shifts, but the idea is the same. "A society grows great when old men plant trees in whose shade they shall never sit." The actions your generations have taken, will have a direct effect on mine and the those that come after. Do you want to leave us with even more of a mess to clean up, or the groundwork for a future where we won't need jet fuel because we'll have something better? |

It's not that "jet fuel is bad" that is the key concern... it's that there's only so much oil to make it out of. One day that WILL run out. What are we going to do then? Production Jet fuel is a mixture of various hydrocarbons. The range of their sizes (molecular weights or carbon numbers) is restricted by the requirements for the product, for example, freezing point or smoke point. Jet fuels are sometimes classified as kerosene or naphtha-type. Kerosene-type fuels include Jet A, Jet A-1, JP-5 and JP-8. Naphtha-type jet fuels, sometimes referred to as "wide-cut" jet fuel, include Jet B and JP-4. "Drop-in" biofuels are biofuels that are completely interchangeable with conventional fuels. Deriving "drop-in" jet fuel from bio-based sources is ASTM approved via two routes. ASTM has also found it safe to blend in 50% SPK into regular jet fuels.[40][22] Only tests have been done so far with blending in synthetic paraffinic kerosene (SPK) in considerably higher concentrations.[41] HEFA-SPK Hydroprocessed Esters and Fatty Acids Synthetic Paraffinic Kerosine (HEFA-SPK) is a specific type of hydrotreated vegetable oil fuel.[2] As of 2020 this was the only mature technology.[15][2] HEFA-SPK fuel is considered to be a leading alternative replacement for conventional jet fuel by the CAA.[42] HEFA-SPK was approved by Altair Engineering for use in 2011.[43] HEFA-SPK is produced by the deoxygenation and hydroprocessing of the feedstock fatty acids of algae, jatropha, and camelina.[44] Bio-SPK This fuel uses oil that is extracted from plant sources such as jatropha, algae, tallows, waste oils, babassu, and Camelina to produce synthetic paraffinic kerosene (bio-SPK) by cracking and hydroprocessing. Using algae to make jet fuel remains an emerging technology. Companies working on algae jet fuel include Solazyme, Honeywell UOP, Solena, Sapphire Energy, Imperium Renewables, and Aquaflow Bionomic Corporation. Universities working on algae jet fuel are Arizona State University and Cranfield University. Major investors for algae based SPK research are Boeing, Honeywell/UOP, Air New Zealand, Continental Airlines, Japan Airlines, and General Electric.[citation needed] FT-SPK Another route involves processing solid biomass using pyrolysis to produce oil or gasification to produce a syngas that is processed into FT SPK (Fischer–Tropsch Synthetic Paraffinic Kerosene).[citation needed] ATJ-SPK Alcohol-to-jet (ATJ) pathway takes alcohols such as ethanol or butanol and de-oxygenates and processes them into jet fuels.[45] Companies such as LanzaTech have created ATJ-SPK from CO2 in flue gases.[46] The ethanol is produced from CO in the flue gases using microbes such as Clostridium autoethanogenum. In 2016 LanzaTech demonstrated its technology at Pilot scale in NZ –using Industrial waste gases from the steel industry as a feedstock for its microbial fermentation.[47][48][49] Gevo developed technology to retrofit existing ethanol plants to produce isobutanol.[50] Alcohol-to-Jet Synthetic Paraffinic Kerosene (ATJ-SPK) is a proven pathway to deliver a bio-based, low-carbon option to travelers.[citation needed] Future production routes Systems that use synthetic biology to create hydro-carbons are under development. The SUN-to-LIQUID project is examining Fischer-Tropsch hydro-carbon fuels (solar kerosine) through the use of a solar reactor.[51][52][53] Alder Fuels raw material is waste from forestry and agriculture. This is mainly structural polymers cellulose, hemicellulose and lignin. They are processed via pyrolysis. The result is condensed into greencrude, a hydrocarbon-rich liquid, which is turned into fuel in refineries.[54] Piston engines Small piston engines can be modified to burn ethanol.[55] Swift Fuel, a biofuel alternative to avgas, was approved as a test fuel by ASTM International in December 2009.[56][57] Technical challenges Nitrile-based rubber materials expand in the presence of aromatic compounds found in conventional petroleum fuel. Pure biofuels that aren't mixed with petroleum and don't contain paraffin-based additives may cause rubber seals and hoses to shrink.[58] Synthetic rubber substitutes that are not adversely affected by biofuels, such as Viton, for seals and hoses are available.[59] The United States Air Force found harmful bacteria and fungi in their biofueled aircraft, and use pasteurization to disinfect t |

We can make synthetic organic fuels from coal, or biomass. It might be more expensive, but the option is there. Germany did it during World War II because they didn’t have enough oil.It is not at all about “running out of oil,” it’s about the fact that the molecular waste* produced by using organic fuels have negative effects and ought to be avoided. The rest of your post is just “OK Boomer” claptrap. *cf. “nuclear waste.” |
