  "definition": "These systems use fluid with a low-boiling point, such as ammonia, to rotate a turbine to generate electricity. Warm surface seawater is pumped through a heat exchanger where the low-boiling-point fluid is vaporized. The expanding vapor turns the turbo-generator. Cold deep-seawater - pumped through a second heat exchanger - condenses the vapor back into a liquid, which is then recycled through the system.",
