Melting Away Ice Hazards

RadioheadKid writes "Dartmouth College Professor Victor F. Petrenko is getting a grip on ice. He and his colleagues have found ways to take advantage of the "protonic" semiconductor properties of frozen water. They see many applications of this discovery from melting ice on power lines to electronic speed control for skis and snowboards. I guess those Petrenkos just love the ice."

4 deg C is greatest density

That's for relatively pure water, and that works out to be about 39 deg F. OF course adding salts and other things to raise the molarity (ionic concentration) of the water will depress the freezing point - I've forgotten what it'll do tho the density curve something about packing inefficiencies
