Hydrocarbons have been really helpful to humankind and some technology relies so heavily on them that we'll not stop using them any time soon. Antonia, Jasmin, Sophie and Alasdair discuss eFuels which are a new source of hydrocarbons that could replace fossil fuels. Sophie and Alasdair talk about the company they have founded called Carbon Neutral Fuels which aims to suck carbon dioxide out of the environment and turn it into fuel for airplanes. The team discusses the different technologies to do this as well as what else it could be used for. 

They also touch on TRLs (Technology Readiness Levels - a way of describing how mature a technology is) and explain some of the terminology used in this new and fast-growing industry.
