SYNTHESIZER: #scifi A device that breaks down unwanted materials and then uses the atoms to make needed products. These products may include anything from food or clothing to furniture, but the atomic composition of the products made must match that of the waste material used. (Surplus atoms can be stored, but the input material must contain all the needed atoms.) Luckily most organic materials have a composition overwhelmingly dominated by hydrogen, carbon, oxygen and nitrogen, and it is relatively easy to add small amount of any missing atoms. The synthesizer breakdown on the Bounceabout in Homecoming is a life-threatening emergency.
