Derek Foxwell about killed me when I asked I could use High Test Hydrogen peroxide to make high pressure steam to power things in Robot wars.

Now I couldnt say I wasnt warned. I made the idea public on the old forum, and most of the old guard warned me Youre nuts.

Its plainly not safe at all. Its next to impossible to provide a safe working enviroment in the pits when you start to use hydrogen peroxide in concentrations abouve 20-25%.

N2O is another kettle of fish. Its simular to CO2 in pressure-temperature-gas-liquid curve, so, you have to store it in a suitable bottle, having a seperate PRV, and then the other effect of the stuff could get funny side effects; Imagine the PRV popping open when you open that bottle. Youll laugh, but if it goes wrong, youll do stupid things, or aspyxate...

Again, on safety alone I wouldn,t allow it.
