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 a hot water rocket except the water is butane and it is heated by a fluid with a much lower vapour pressure.
