Unfortunately, I don't think it's possible. You'll have to add enough energy to heat the liquid to its boiling point and also enough energy to make it all evaporate. (The liquid to vapour phase change consumes a very large amount of energy btw.)What you are describing is not so different from the way a steam engine or steam turbine works. Sadly, they are not terribly efficient, so a substantial amount of heat energy always gets wasted.
Thermodynamics is a cruel master!
If you would like to try different scenarios, and learn a lot about Thermodynamics at the same time, go to http://www.thermofluids.net/You'll find a lot of great information there as well as a free calculator that lets you model different systems while avoiding the tedium of a lot of lengthy manual calculations.One of the things you could try is just turning a certain mass of water into steam, first by raising its temperature to boiling point, then converting it into steam.
Heat engines can only operate when there is somewhere for the heat to flow to.
