I chose [http://en.wikipedia.org/wiki/N2O N<sub>2</sub>O] over [http://en.wikipedia.org/wiki/Oxygen O<sub>2</sub>] because although N<sub>2</sub>O carries a lot of conjectural inert nitrogen (64%) oxygen is much harder to handle (tank filling, storage & injection). Additionally the [http://en.wikipedia.org/wiki/Nitrogen nitrogen], though not participating in combustion, raises the fuel erosion rate and cooles the nozzle enough to reuse it many times. | I chose [http://en.wikipedia.org/wiki/N2O N<sub>2</sub>O] over [http://en.wikipedia.org/wiki/Oxygen O<sub>2</sub>] because although N<sub>2</sub>O carries a lot of conjectural inert nitrogen (64%) oxygen is much harder to handle (tank filling, storage & injection).
