    Everything I have heard about sustainable jet fuel basically points to it being a pipe dream. Bio fuel is not effectively scalable and shows no hope of being so. Where synthetic fuel just increases the energy input per unit of fuel. Neither one addresses the fact that petroleum combust engines at a high altitude have a much greater impact than ones on the ground due to the fact that they inject particulates into the stratosphere. This needs to be placed in the bin as “clean coal”
