I think biologically produced nanocomputers might be do-able, but the likelihood is that there will be far more efficient ways to build them. The kinds of nanocomputers that might be produced in living cells are bound to be far more limited than the ones we'll be able to make with general purpose nanomachines that are specially designed to handle all sorts of types of atoms and atomic clusters. I refer all of you who are interested in nanotechnology to Eric Drexler's masterpiece called "Engines of Creation." It is >the< book to read on the topic, and it just came out in paperback. Sorry I don't have pub info on hand right now. I recall one image that might be worth some discussion. In the book Drexler describes a system where rocket engines (and virtually anything else you could imagine) would be grown in vats. One "seed" machine the size of a very large virus is dropped into the nutrient mixture, and it in turn assembles machines that then assemble other machines, and so on, until eventually this wondrously detailed macroscopic structure begins to emerge. The potential kinds of things we could build with such a system are unlimited. If you could design such a system, how would you make it work? What sorts of stuff would you build/grow? What kinds of atoms and molecules would you use in your structures? How would the nutrients be circulated? How would you deal with the inevitable waste products? How would you supply energy to the nano- machinery? These are important questions. Any ideas out there? NickyT
