Instant Windshield Deicing with PETD

PolarStar | Tue Jan 31, 2012
A PETD-enabled windshield can be deiced in 6-10 seconds from a cold start.

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 de-icing (PETD).
