Bending salty ice up to 1,000X more efficient generating electricity than bending pure ice; could be sustainable power source

"streaming flexoelectricity: electricity generation by bending material... salt prevents ice from freezing completely, creates tiny channels filled with salty water, pressure from bending forces liquid flow through channels, electric charge in moving water creates streaming current... ice covers around 10% of Earth's surface so may also be relevant to electrical activity of ice-covered terrestrial regions and distant icy ocean worlds... drawbacks: up to 80% less power after numerous bends, more waste heat than piezoelectrics"
