Let me first suggest that returning water directly to the river, unpolluted and at its original temperature, is in itself a useful purpose. The point is to draw as much heat from the water as possible and use that heat for some useful purpose. The question is, what the limit of heat transfer -- that is, at what point in the heat-recovery process does it become thermodynamically or economically inefficient to recover more, and how much warmer than ambient is the cooling discharge at that point?

My students are currently working on a project to design and create model structures that would reduce or completely inhibit the return of warmed water from power plants back to the enviroment, with a focus on re-using the water for a productive purpose. Your sight has been useful to gather info. Any other ideas or resources you can suggest for us? Thanks. Traci Dorsey I am a science teacher at a private high school in NH.
