Butane/Hot water rocket

Is it feasible to make a rocket from butane and hot water? The hot water and luke warm butane are pressure fed into a chamber, like a combustion chamber, but where the two fluids mix turbulently and come into thermal equilibrium, the butane expands and the mixture then exits out the back. A bit like...

mixed fuel - CO2/propane

I read that non pulsing pressure jets which use superheated propane to compress air in an ejector are limited because they cannot entrain enough air to work efficiently. Would it be possible to mix, say (off the top of my head), 3 parts CO2 to 1 part propane in the same cylinder and use this to fuel...

windmill-jet

Hi i'm a newbie. This is slightly tongue in cheek but, I had an idea for an unconventional engine a few years ago and wondered if anyone here would know if it might work. Its not the most useful of engines as it would probably need a 'bump start' of several hundred miles per hour to get it going. It...
