I'm not sure how dangerous that is, but it did give them an engine with fewer moving parts:
"It is lifted by a thin, 17-foot rotor blade that whirls just above the pilot's head under the power of hydrogen peroxide fuel broken down by catalytic action into steam that is ejected at high speed from the rotor tips."
"Ultrasimple, it has no pistons, no electrical system, no lubrication or cooling system, no clutch, transmission or starter."

- ncmncm 8y agoThe latest design, with a better catalyst matrix, works with 50% H2O2. That matters because you can buy it, and don't need to make it yourself on the spot like the 70% solution. I have not succeeded in finding out whether the rocket version is loud like the ramjet one.
