Mel, We've never tried 70%, because we had access to 90%+ HTP, and there is no need to prove something would work with 70%. For actual flights, its pointless to carry 30% water with you. It clearly would be more difficult to catalyze as well, and the Isp would be poor.
Frankly, individuals or small businesses will not be able to find any 85%+ available from any source. Even FMC is getting very reluctant to sell to any non-governmental groups.

It is said to produce 200 pounds thrust on 90% hydroegen peroxide--would it produce any thrust at all on 70% hydrogen peroxide? As it appears that is the highest percentage obtainable through industrial sources. If 90% is obtainable, can anybody tell me where it may be obtained. Any help on these two questions would be greatly appreciated.
