Hotter water will provide faster melting but I think the jetting of the warm water from Ice Pick will also serve to increase the melting efficiency because of the motion of the jetted material. Stirring your ice tea melts the ice faster than if it is not stirred. ____________________   That's one conclusion reached with absolute certainty by the Cryobot design teams already -- using active hot water jets vastly increases the efficiency with which it melts through the ice, and in fact is now considered an absolutely necessary feature (quite apart from their ability to wash away the non-ice sediment that otherwise builds up in front of the Cryobot's nose).
