Cooling Off (1955)
An operator opens one of the condenser valves at Schiller Station in Portsmouth, NH. When the valve is open, river water is able to cool off the exhaust steam from the turbine—which sits above the condenser—thus squeezing the last bit of energy out of the steam to maximize unit efficiency. This completes the Rankine cycle, converting heat into energy. The same valves exist at Schiller today.
