You explained enthalpy very well. I still remember learning about it in a thermodynamics class.

You really need to read up on some science. Steam is a phase change for water and the latent energy is released in the steam that is not available in the water. Steam expands greatly while water does not. Water is an excellent latent heat capture material and it is the pressure from the phase change expansion that allows the energy to be extracted in driving turbines. Hot water doesn't drive turbines without a pump, steam does. This is very elementary science, something a person might learn in a decent elementary school as a science fair project.
