    To cook food, a microwave oven converts voltage into high-frequency electromagnetic microwaves. The molecules in food—especially water and fat—absorb this energy and wiggle at high speeds, causing them to heat rapidly and warm the surrounding food. Microwaves can only speed up atoms, not slow them down.

    There is a method for slowing atoms, however: lasers. Shoot a moving atom with a laser, and it will absorb the laser’s photons and re-emit them every which way, causing the atom to hold nearly still. Placing an atom at the junction of multiple beams can slow its momentum in all directions, decreasing its energy and cooling it. This drops an atom’s temperature a couple hundred degrees Fahrenheit in less than a second. But because it works most efficiently on low-density gases of atoms of a single element, it will not be useful for cooling food anytime soon:

    A refrigerator is my best guess. I know your looking for something that's more advanced but you might want to check out vortex cooling. Vortex cooling uses a small pneumatic pressure, turns in into an extremely high pressure and by using coils around (whatever), causes the same affect as refrigeration but less than freezing. An extremely reliable source of energy (low pressure-less Oxygen consummation) and works well with cooling, say electrical devices.
