Mitsubishi Electric has given us the gift of green. A new fridge will actually enhance the nutrients in your vegetables the longer they stay in.
The box gives off orange light-emitting diodes (LEDs) that promote photosynthesis in the greens. Typically vegetables lose vitamins and other such goodies the longer they stay in the fridge, but now that process will actually be reversed. Truth be told, however, I tend to only eat vegetables when they come topped on pizza. So really this does me no good.
Also related is a refrigerator that actually keeps things cool by using sound. Researchers at Penn state actually designed a refrigerator which makes such loud sounds that the gases inside the box constrict and cool down. I hope they figure out a way to turn off the sound when you open the fridge, like that annoying light I always try to catch off.
