Could nuclear power be the key to sustainable motoring? We don't mean putting atomic reactors under car bonnets. What we mean is: whether nuclear power could generate electricity so cheaply it could be used to mass-produce biofuels. They work in conventional engines, and altogether this could make it much easier to  decarbonise motoring. 

So far so logical, but is it achievable? That's the question we discuss with Dr Tim Gregory, nuclear chemist and author of ‘Going Nuclear - how the atom will save the world’.
