This week we talk about natural gas, plumes, and satellites.We also discuss firedamp, AI detection, and emission numbers.Recommended Book: Excellent Advice for Living: Wisdom I Wish I'd Known Earlier by Kevin KellyTranscriptMethane, the name for a chemical made up of one part carbon, four parts hydrogen, is incredibly abundant on earth as it's formed by both geological and biological processes—the former when organic materials are heated up and have massive amounts of pressure applied to them, underground, and the latter through a process called methanogenesis, which basically means certain types of Archaea, a type of life, exhaling methane.That sort of respiration mostly occurs in organic-breakdown situations, where these microscopic organisms live: so landfills and in the bottom of lakes, where dead stuff falls and is torn apart at a microscopic level by these tiny creatures, but also in the guts of cows and termites and similar beasties, which rely upon their symbiosis with these archaea to help them process the stuff they eat—which they otherwise wouldn't be able to break up and use on their own.Methane was originally discovered, in the sense that it was noted and quantified, back in the late-18th century, when the Italian physicist and chemist, Alessandro Volta—who among other things also lent his name to an electrical measurement and who is credited with inventing the battery—who was studying marsh gas, marshes being a huge natural source of methane, as it's filled with the sorts of critters that break apart biological materials and release methane as a byproduct. We've known about this gas for a while, then, and history is filled with examples of different cultures making use of it in relatively simple ways, as an energy source. And on that note, methane is the primary constituent of what we today call natural gas, though the name methane was only coined by 1866 by a German chemist, August Wilhelm von Hoffman, who derived the term from methanol, which is the flammable, colorless liquid often called wood alcohol which is from whence the gas was first detected and isolated, and before that different cultures referred to it only adjacently, usually because it caused issues they couldn't quite quantify, like, for instance, causing deaths in coal mines—the deathly, gas-pocket-laden air, until methane became an official thing, sometimes referred to as firedamp, which was scary because it could suffocate everyone, or it could explode.Today, methane, mostly as a constituent of natural gas, is harvested and shuttled all over the world to be burned as a fossil fuel; and similar to other fossil fuels, like oil and coal, that burning releases energy, producing heat, which is used to spin a turbine or heat water in a steam generator. Natural gas is, in the modern world, generally considered to be superior to other fossil fuel options because it burns relatively cleanly, in terms of pollution, compared to other options, which is nice for folks in the areas where this burning is taking place, but it also releases relatively less CO2 into the atmosphere per unit of heat it produces when it's used for energy, so although it's still very much a fossil fuel and emits greenhouse gases into the atmosphere, it's the best of bad options in many ways, and can be stored and transported in forms that make it quite versatile and even more energy-dense—it can be refined and pressurized into a liquid, for instance, which makes transport substantially easier and each unit of natural gas more useful, but that also allows it to be used as rocket fuel and for similar high-intensity utilities, which is not something that can be said of otherwise comparable options.What I'd like to talk about today is the role of methane in a world that's shifting toward renewable energy, and why this fossil fuel, which is generally superior to other fossil fuel options, is associated with some unique problems that we're scrambling to solve.—Back in June of 2023, scienti
