> condense the steam

That's what the water is for!

Turbine systems follow the Rankine cycle, https://en.wikipedia.org/wiki/Rankine_cycle , which includes a condenser. The water circulating is a closed loop. The steam you see coming off cooling towers is the external water which has been used to condense the circulating steam.

The water is a source of "coolth".

i know what the water is for i'm saying there is no need to release the steam and have to pump additional water for cooling; you can also use radiators to cool water down etc. as i said the additional water and steam stacks are a quick and easy method for cooling when a water source is nearby. there are other options that can be used when water isn't available.
