Eating into the Future
I have always been intrigued by the food synthesizers in the "Star Trek" universe, which can produce any food in its database with a single command. It does use some form of transporter technology to create the dish requested, but we are already making strides in that area with 3D technology which allows us to "print" any object, including body parts, that we need.
Not only are we currently able to analyze all (or almost all) the ingredients in any food product, we can also genetically enhance natural substances to create better-tasting or longer-lasting variants. Our world's population is growing, and much of it is starving. Conventional food production cannot keep up with the increasing demands for food.
As the world's foremost inventor, I would marry the ideas of 3D printing and chemical analysis to create a first-generation food synthesizer. It would have a voice interface not unlike those on most smartphones today, so all you'd have to do is say the name of the food you want and the temperature you'd like it to be, and - presto! Your food is ready to be eaten.
