Documentary.these guys are great, very enjoyable.
The video starts with the first test. It uses a hydrogen peroxide gas generator. The video goes on to show the various parts of the V2 rocket inspired turbopump.
This is the first time I've seen amateurs building a turbopump.. pretty amazing I think.
The results were overwhelmingly positive: We have more than doubled efficiency, and we had demonstrated that a Svanehøj-fire pump can supply 20 liters of liquid per second at up to 18 bar, driven by a turbine we have built. It is both higher pressure and greater flow than we need. And the best part was that despite the more than doubled the pump power is not increased our consumption of T-stoff.
We have found on all unregulated tests seen that the steam generator very briefly rendered slightly more at the T-stoff burnout. We have not quite no explanation why, but apparently something happens differently in the catalyst when flushed with a mixture of T-the substance and propellant. This power spike came as test # 5 ran out. And it was the straw that broke the damaged sheet to crash. Just as we burned out, changed turbine sound slightly. Inside, the damaged leaf caved in and become detached. It took manifest a trip or two around while a number of other turbine blades went in sympathy strike.
Ouch, T-stoff. There are much more enjoyable ways to kill yourself.

Well I dunno. It inspired me to go off and read about " "-Stoff[1]. They came up with a BUNCH of nasty mixtures back then. Was it on-thread? probably not. But you don't have to be snide.

Concentrated hydrogen peroxide is an extremely dangerous and unstable oxidizer. I am profoundly concerned for anyone having to deal with it, especially amateurs. Too many professionals have been killed by it. Copenhagen Suborbitals would not survive a fatal accident.

Please give a reference of the "Too many professionals have been killed by it." statement. I know of only person killed by HTP (85% H2O2).
Another anecdotal story from Woomera is that for fun they would pour HTP onto plants and watch them burst into flames!
Does a liquid that bursts plants into flames sound very safe?
It's 80% H2O2. LOX is just as "dangerous".
FFS, it's 80% H2O2. LOX is just as "dangerous".
HTP as used by the British at Woomera is 85% H2O2. Copenhagen Suborbitals are using 90% H2O2 (http://www.wired.com/wiredscience/2013/03/diy-rocket-grade-hydrogen-peroxide/).

No, it doesn't, because in this case HTP was being used in an unsafe manner. Handling LOX or any other oxidiser in such a manner is just as unsafe.
Madsen seemed to have good protective gear while loading HTP to the TP test thingie ... but the flimsy household ladder looked risky. Stack those concrete lego bricks for a stable platform, or better yet, lower the tank to ground level.
