Pulse deicing

Because in pulse deicing (braking) the heat diffusion lengths are typically much shorter than the thickness of the ice and that of a substrate, the result would not depend on the materials thickness at all, to simplify boundary conditions we can consider infinitely thick layers of the materials ... 

A recently invented Pulse Electro Thermal Deicer (PETD) [2], successfully overcomes that high-energy requirement limitation by effectively isolating an ice-solid interface from the environment. When optimized, a pulse deicer requires only 1% of the energy conventionally used in thermal deicing and can deice surfaces in less then one second. This technology has... 

In deicing applications the refreezing time should at least allow for the ice to slide off of the surface before the interface refreezes. However, in a pulse electro-thermal brake, this refreezing time should be as short as possible to prevent slippage of the slider before the interface refreezes.
