A method for controlling a coefficient of friction between an object and
ice includes steps of (1) pulsing power to an interface between the
object and the ice to melt an interfacial layer of ice at the interface
and decrease the coefficient of friction, (2) facilitating refreezing of
the interfacial ice at the interface to increase the coefficient of
friction; and (3) repeating steps (1) and (2) to control an average
coefficient of friction between the object and the ice. A slider having a
surface intended to interface with ice or snow includes a power supply
for generating power. The slider also has a heating element that converts
power to heat at the surface, the heat being sufficient to melt
interfacial ice at the interface, and a controller for controlling
delivery of power to the heating element to control friction between the
slider and the ice or snow.
