Take CO2 from the Air, combine it with Hydrogen extracted from Water ( using renewable energy) and you can make various fuels like ethanol, diesel, kerosene, petrol and aviation fuel. Fuels made like this can notionally get to Net Zero, although are more likely to generate 90% fewer emissions than the conventional hydrocarbons. Still pretty good, and another benefit is they work without needing expensive modifications to the car or plane. https://carbonengineering.com/news-updates/ce-lanzatech-jet-fuel/
Nuclear is becoming a hot topic as a source of clean energy so we decided to have host a conversation about it. Nuclear power remains banned under two Australian federal laws, but it’s an industry with a lot of industrial potential. Among 60 recommendations in a recent NSW Productivity Commission white paper was lifting a ban on nuclear electricity generation for small modular reactors.Many Australian political discussions don't consider latest developments in SMR's but now that Australia is contracting to buy nuclear-powered submarines we should. According to our discussion Australia could even benefit from a circular economy in uranium.https://youtu.be/uypAIsQdaWI
For Type 4 & 5 plastics, upcycling is hard. It requires two stages, temperatures of over 200°C, lots of energy and the process can produce undesired by-products.Researchers have identified a one stage, faster process, requiring less energy and temperatures of around 70°C. The process also minimises unwanted by-products and still produces desired chemicals, fuels and other high-value materials from the plastic waste.https://www.anthropocenemagazine.org/2023/03/plastics-to-fuel-in-one-quick-step-using-minimal-energy/
