Ethanol could fuel a jet engine, but kerosene has a higher energy density.
Ethanol production doesn't tend to be carbon neutral either, though maybe it's closer than petroleum pumped out of the ground.
- jjoonathan 9y agoMaybe it's better than petroleum? The hell? It's not only better, EtOH becomes entirely neutral in the limit where it takes over. The carbon released from burning all comes from the plant, which in turn all comes from the air. All other carbon costs are incidental (e.g. it doesn't make sense to immediately convert transportation, farming, and production equipment) or one-off and amortizable (ploughing fields).
