Required information
The oceans in the tropics have substantial surface-to-deep-water temperature gradients. Depending on the location,
relatively constant temperature differences of 15°C to 25°C can obtain for depths of 500 m to 1000 m. This provides the
opportunity for using cold (deep) water as a heat sink and warm (surface) water as a heat source for a power cycle. The
technology is known as OTEC (Ocean Thermal Energy Conversion).
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
