Ethanol fuel was always a mystery to me. Really, I never took the time to learn about it until I watched this 3:31 video that shows how a Pennsylvania company, Coskata, converts anything that contains carbon into fuel. Yeah, it’s an infomercial for GM, but it always quickly explains the whole waste to fuel conversion process and so it might be worth your time.










What’s the residual waste product though? The stuff that’s left over from the feed when the ethanol is extracted? And what do they do with that?
GM’s YouTube video has its comments disabled, so I can’t ask them that.
I’d like to know how much energy they consume to produce an equivalent amount of fuel.
