Hi Josh,

The last time I tried it the water got cold.   Seriously though, if you put dry ice in water it looks as if it's boiling but that is just the dry-ice, really solid carbon dioxide, turning into the gaseous phase and making bubbles.  The net effect is to cool the water.

You could do it indirectly. You could run a heat engine off the temperature difference between the ice and the room, say using a thermoelectric cell to generate current. The current from that cell could then be used to drive some sort of electric heater to boil a little water.
