Hi Gary

He says that H2O2 is stable if pure, but metal impurities "catalyse" its decomposition, thus it has to be kept in special containers. He claims he put some peroxide rockets on a bike! Serious bit of pace there! Plus he has made a jet-pack - of course, being one of the early uses of peroxide as a monoprop, but only ~ 160s Isp.

Mark Wade's site says that it's been successfully used as an oxidiser with hydrocarbon fuels - I've pondered it as an alternative for deep space missions to N2O4. From what I've read it's not made from water, but a number of different pathways can make it - electrolysis of ammonium bisulphate being one commercial process.
