A Humanitarian Invention

If I could invent a Machine to enrich the future, I would create something like the replicators from the "Star Trek" series.
this device would be able to create what ever provisions a man may or may not need at any given time, as well as luxuries. The device would be able to extract molecules from the air, move them to a central holding unit, and repurpose them to whatever the subject requires at that moment. However, this machine does have limitations. The replicator is limited to any type of food, beverage, clothing, or basic needs like a tent. It will not fabricate any money or weapons, because it is strictly a peaceful invention.
This machine could benefit people because anybody can always have food and water, as well as clothes. There would no longer be a worry about famine or drought, because all that a person needs it at the tip of their fingers.
