Among ocean energy sources, OTEC is one of the continuously available renewable energy resources that could contribute to base-load power supply. The resource potential for OTEC is considered to be much larger than for other ocean energy forms [World Energy Council, 2000]. Up to 88,000 TWh /yr of power could be generated from OTEC without affecting the oceanâs thermal structure [Pelc and Fujita, 2002]. Systems may be either closed-cycle or open-cycle.
Messenger Plus! allows to export all its preferences and save them into a single file (.pld) on disk. The .pld file is a binary database container that uses Yuna Software's proprietary format to store the exported settings and preferences.
