Welcome back to The Information Entropy Podcast! This week, we’re diving into the sticky, smelly, and utterly essential world of oil. We start underground, exploring how ancient fossils turn into crude oil, and follow it all the way through fractional distillation and chemical refining—yes, cracking, reforming, and hydrotreating are actually real things that chemists do every day. We’ll talk about the environmental impact of fossil fuels, from spills to climate change, and then look forward to modern alternatives like biofuels, algae-based oils, and synthetic e-fuels. Finally, we ask the big question: how long until these sustainable fuels can really take over? It’s a journey from deep time to your gas tank, and everything in between.
