That gets you the worst of both worlds: it's cryo, *and* it's an energetic monopropellant just waiting for an excuse to do a spectacular solo performance. In the case of *clean* nitrous near room temperature, the excuse at least has to be a good one -- the nitrous in the Scaled Composites accident almost certainly had organic contamination -- but ozone is less fussy. Much better if all the heats of formation are negative until things mix in the chamber...

Oh, and you have to make it rather than buy it, because nobody in his right mind will make it for you.
