The paper presents designs for a practical thermomechanical engine that can generate electrical power from seawater using the extreme chill of frigid polar air as a heat sink. Latent heat from freezing seawater boils a high pressure natural refrigerant and drives a vapor expander to generate power. The temperature difference between seawater and cold wind is small, but a large amount of heat is generated per ton of ice produced equivalent to heating liquid water by 80 C. End-to-end thermal efficiencies of 510% at interior sites embody equivalent power to the same mass of freshwater sent through a hydro-dam 1,7003,400m tall. Commercial refrigeration technologies might be readily adapted for electricity production. Practical, clean and affordable glaciothermal power generation represents a significant and timely development in energy technology.
