I wonder why the author is so caustic in regard to hydrogen peroxide.<p>Here - <a href="http://yarchive.net/space/rocket/fuels/peroxide.html" rel="nofollow">http://yarchive.net/space/rocket/fuels/peroxide.html</a> - second message mentions Clark's "Ignition!" facts, and in first Henry Spencer states:<p>While there are some storage headaches -- the stuff decomposes slowly no matter what you do, so you must provide for tank venting -- otherwise peroxide is much easier and safer to handle. Its bad reputation is half outright myth and half the result of 1940s experience with seriously impure peroxide. To quote a friend, a rocket-propulsion professional, who investigated the matter as part of a study some years ago:<p>"As far as we could find out, the stories about problems with peroxide were just that, stories... Peroxide, now, seems to only very rarely do anything exciting, at all. And, even then, it seems to never do many of the things attributed to it in the stories."<p>Of course hydrogen peroxide can be dangerous - relatively recent explosion in Sweden (peroxidepropulsion.com) reminds us about that. At the same time significant volumes of it with more than 70% concentration are routinely used - so a chemist can calibrate the feeling.
