Mist Lift is a form of Ocean Thermal Energy Conversion (OTEC) wherein a waterfall is created within the sea to operate a hydro-electric turbine. Mist Lift takes place inside of a low-pressure concrete vessel submerged a few feet below sea level. A vacuum pump maintains the low pressure causing the falling water to quickly evaporate. Cold water is strategically injected upwards into the warm mist causing it to condense whereby a pressure difference acts to accelerate and lift the water back to the surface, keeping the vessel clear for new water to continue falling through the turbine.

Mist Lift does not require large pumps and heat exchangers and is much more efficient than other types of OTEC. Less cold water for the same energy output equates to significant cost savings due to the smaller pipes required.
