<p>>Iran would have to respond and thus would have to try to find a way to inflict ‘pain’ on the United States to force the United States to back off. But whereas Israel is in reach of some Iranian weapons, the United States is not.<p>This is too complacent for my liking. Every rusty trawler is a viable launch platform for Shahed type drones (operational range ~2500 km per Wikipedia). Nearly every US oil refinery and LNG terminal are on the coast. And then there are floating oil platforms (e.g.: <a href="https://en.wikipedia.org/wiki/Perdido_(oil_platform)" rel="nofollow">https://en.wikipedia.org/wiki/Perdido_(oil_platform)</a>)<p>The article then says:<p>>One can never know how well prepared an enemy is for something.<p>And:<p>>And if I can reason this out, Iran – which has been planning for this exact thing for forty years certainly can.<p>I'll leave it here for y'all to ponder.</p>

<p>Yes, it is nothing like 2022 <i>yet</i>. But the concerning thing is that this may be just a beginning of a protracted event, plus the world, and especially Western Europe, is less resilient today to the disruptions in gas supply.</p>

<p>Yes it does. Consider too that after kerosene whaling declined while world population, wealth and demand for lighting grew rapidly.<p>Also, kerosene for lanterns became a thing in 1846, not 1865 as claimed in the article, and by 1856 was already widespread. Wikipedia has this to say about its impact:<p><i>As kerosene production increased, whaling declined. The American whaling fleet, which had been steadily growing for 50 years, reached its all-time peak of 199 ships in 1858. By 1860, just two years later, the fleet had dropped to 167 ships. The Civil War cut into American whaling temporarily, but only 105 whaling ships returned to sea in 1866, the first full year of peace, and that number dwindled until only 39 American ships set out to hunt whales in 1876.[36] Kerosene, made first from coal and oil shale, then from petroleum, had largely taken over whaling's lucrative market in lamp oil.</i></p>

<p>The really big problem in open source intelligence has been for some time that data to support just about anything can be found. OSINT investigations start with a premise, look for data that supports the premise and rarely look for data that contradicts it.<p>Sometimes this is just sloppy methodology. Other times it is intentional.</p>

<p>Ooh, I love pedantry contests!<p>Let's go back to your opening comment which was something like "I thought methane was 80% hydrogen on a molar basis". Methane does not contain H2 molecules, it contains 4 atoms of hydrogen. Plus one atom of carbon, which would indeed make it 80% hydrogen on a molar basis.<p>If that does not convince you: note also that atomic carbon is also a very unstable, and will auto polymerize into one of its allotropes (eg. C60 - buckyballs). And yet we count carbon by the atom.</p>

<p>"Molar" refers to a number of elementary entities, which could be atoms or molecules or w/e. So yes, if you are counting moles of H2 gas, but not if you are counting atoms...</p>

<p>No, that is not right. The correct answer is "it depends", but let's run some indicative numbers on data for Boston:<p>On average and excluding the minority of routes with dedicated lanes (which may be best run on diesel), the Boston metro buses are in use for 6.6 hours per day, covering on average 53 miles.<p>A full size electric bus uses electricity at a rate of approx 2 kWhr/mile.<p>So, on average the bus would have around 17 hours to charge up with 106 kWhrs of juice, and this averages out to about 6.2 kW. On average.<p>However, the smart thing to do would be to charge the buses when the power costs the least, say between 10 pm and 8 am, so you'd need ~10 kW/bus, maybe ~1MW for the 100 bus fleet. Not difficult.</p>
