No, it's possible to boil the water to make steam

It is impossible to recover nearly as much energy from that that steam as it would take to boil it.

It's not a 'today's technology' thing it's a law of thermodynamics thing.

Water is not a source of energy, it is a medium of energy transfer.

Every kg of water at boiling point being converted to steam takes say 2133 kJ of energy.

You cannot then power a generator with that steam and get more than 2133 kJ of energy out of it. Your actual efficiency of a steam generator is 10-40%

So now you have 2133 x 0.4 = 853 kJ of electric energy.

So you take 20% to the boiler and you have 170 kJ of energy. Which is not enough to boil a kg of water.

Even if you had an impossible 100% efficiency boiler, steam system, turbine and battery system you'd never be able to pull even 1 kJ out without decreasing your steam volume.
