How fast the energy is provided (power, in joules/second or watts) is irrelevant, as long as not too much energy gets radiated away. What you really need to know is how much energy (in joules) is needed.
Iodine sublimes - it does not melt

No, but an aluminum can can be recycled using much less energy than it takes to separate an equivalent amount of aluminum from its ore.

The rate at which water freezes depends on the thermal conductivity of the container. Plastic is generally not very thermally conductive, whereas aluminum foil is more thermally conductive. Thus, as long as the foil is not very much thinner than the plastic, the water will freeze faster in the foil.
