4. Protein Printer This is only hardware part of whole procedure. It will produce desired real proteins from amino acid sequence received from software. It may be able to work in any of two ways:

* Artificial Ribosome: It will mimic functionality of cell to produce proteins. We will generate an mRNA using some assembling mechanism. Then, our artificially designed Ribosome will translate it into a protein which we can use. * Artificial Recombinant DNA: We will assemble a fragment of DNA corresponding to desired amino acid sequence. Then by using some automated means we will introduce DNA into a colony of E. coli (or some other organism)/ Then E. coli will produce these synthetic proteins in same way they produce natural proteins in recombinant DNA technology.

5. Conclusion Using this system, we only need to define: "What do we want protein to do?". All other procedure is automatic. We just need to tell if we want a protein to degrade plastic, convert CO2 into diamond and oxygen, and catalyze/initiate cold fusion, etc. & we will have ready made proteins. It can also help in finding proteins which will help us attain Immortality.

The potential is immense. The only need is its correct use.
