I refuse to assume otherwise. To do so would be to ignore one of the most fundamental lessons of the history of propellant chemstry: As Clark liked to put it, "there's always a 'but'...". IMHO, any catalyst system that will operate reliably without needing more than 35-40 C liquid peroxide inlet temperatures shoule be worthwhile if it will withstand operation at >96% H2O2 concentrations. (And if all else fails, there's always electrically boosted regenerative trickle preheat... if we can't do something clever with catalyst chemistry, after all, I've got some thoughts on how we could still pound the problem into submission with plumbing...) -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
