There are basically two ways to melt ice. Either add heat or lower the freezing point of water. Most of the answers give alternate ways of heating ice (friction, microwave........etc.) The freezing point of water can be lowered by adding a contaminant like salt. Salt will only go so far. It will not melt ice below about 15 degrees F.

Friction - which technically is kinetic energy aka heat. One idea which does not include any heat is:...water. Water at 32 degrees F will melt the ice somewhat. Until they reach an equalibrium of water /ice

It is possible to lower the pressure at a given temperature which allows a solid to melt or even vaporize (depending on the pressure-temperature combination). You would need to look at the phase diagram of water to see what temp and pressure could make this occur.
