You're in Houston, questions of Oil & Gas and energy sources will be naturally be bandied about.
Brandon Sanderson (paraphrased)
Naturally.

Is the gasoline on Scadrial a fossil fuel or biodiesel?
Brandon Sanderson (paraphrased)
Oh. Hmm. Well It's fossil fue... No. What they're using now is mostly biodiesel, I think. It's not something we really talked out.
Cadmium (paraphrased)
Ok, we had a whole thread on 17th Shard and even discussed how scientifically fossil fuels could have been put into place during the Catacendre.
Brandon Sanderson (paraphrased)
Well, fossil fuels are possible, and I don't want to seem like I'm clearly giving credence to those that believe in a Young Earth, but Scadrial is a relatively young planet. Relatively.
Cadmium (paraphrased)
Young Earth doesn't bother me, though I know I'm not the majority.
Cadmium (paraphrased)
Where on Scadrial is it being produced? No mention of refineries in Elendel or the Roughs.
Brandon Sanderson (paraphrased)
Where on Scadrial... Well it's... I'm going to have to RAFO that for now. It starts to touch on questions of the future as they will need more fuels for travel and they'll need to look for different sources.
