Mist lift
![Example Mist flow power generator. A: Vacuum pump which maintains low pressure in the structure.
B: Inlet to allow warm water surface water to flow down to the turbine.
C: Base of the structure 100M below surface where the turbine is located.
D: Cold water pipe which extends to depth (usually 700 to 1000 meters depth).
E: Location where cold water jets spray upwards into vessel.](/Images/godic/202502/13/Mist_flow_OTEC_power_generator_compact5719.jpg")
The Mist lift, Mist flow or Steam lift pump is a gas lift technique of lifting water used in a form of Ocean Thermal Energy Conversion (OTEC) where water falls to operate a hydro-electric turbine. The water is pumped from the level it drops to using rising steam which is combined into a multiphase flow. Independent of energy production, the technique can be used simply as a thermally powered pump used to raise ocean water from depths for unspecified uses.
