Summary

Story summary

Chinese scientists at Xi’an Jiaotong University report ice can generate electricity via flexoelectricity, with salt as a catalyst.
Salty ice is about a thousand times more effective than pure ice.
The findings are published in Nature Materials and Nature Physics; energy from ice covering about 10% of Earth’s surface could reach Europa and Enceladus, though fatigue and low efficiency limit.
