Making "Star Trek" Type "Replicators" Reality
A way to create a Star Trek type replicator might be to create a "3D printe r" which uses particle beams to print matter into the desired form. By usin g particle beams wherein the particles are composed of different elements, it should be possible to create very complex structures with very complex c omposition, possibly even food. Perhaps by using colliding particle beam type fusion it may be possible to use a small number of elements (hydrogen only, for example) to create any e lement through fusion. Then it should be possible to "replicate" the desire d product at very low cost.
