Tour of Dartmouth/Petrenko Ice Laboratory (cold rooms)

Dartmouth Engineering Professor Victor Petrenko and his research team discovered that applying short pulses of electricity directly to an ice-material interface produces some novel and desirable effects. This discovery led them to invent an ultra-fast and efficient method of ice removal and prevention called pulse electro-thermal deicing (PETD).

The heating effect of Petrenko's thin-film, PETD technology creates a melt-water layer with nearly perfect efficiency to deice windshields, power lines, roofs, roads, walkways, runways, refrigerators, airplane wings, helicopter blades, and wind turbine blades, just to name a few.
