Method for generating electrical power using low temperature thermal energy in tropical/near-tropical oceans, involves alternating evaporation and condensation processes of carbon dioxide and/or nitrous oxide in pressure build-up stations

摘要

The method involves alternating the evaporation and condensation processes of carbon dioxide (CO2) and/or nitrous oxide (N2O) in the pressure build-up stations (10-13). The pressure build station is comprised of one or more high-pressure cylinders. Each high-pressure cylinder is comprised of a ring of heat exchangers and a separating piston for the separation of water and CO2 or N2O. A water loop is formed at the downstream of a counter-pressure Francis water turbine (T).
