This is one book which every immortalist should read. Please purchase a copy -- I'm a librarian, but I think people who write this kind of book should profit from it. Maybe we'll get more. (I want to thank "The Immortalist" for pointing out this book in their February, 1985 issue.)

MOLECULAR ENVIRONMENTS FOR ASSEMBLY AND OPERATION There is a wide variety of environments for both the assembly and operation of molecular structures. These environments may be very uniform, or may vary sharply over very short time and space scales. The parameters that may be varied include temperature (cryogenic, etc), pressure, phase (gas, aerosol, liquid, liquid crystal, gel, solid, etc.), chemical (pH, polarity, etc.), electromagnetic fields, particle currents (electrons, protons, neutrons, etc.) and so on. Transport of molecular structures between these environments may be used. For example, at the extreme lower end of the temperature scale, one could make microscopic cryogenic castings of parts using many liquids, some (room temperature) gases, and other materials. Tiny superconducting loops attached to nonconducting components would allow such building blocks to be "glued" and "unglued" to each other by switching indefinitely persisting currents on and off. All sorts of electrical machinery, including magnetic bearings, electromagnetic mass transit systems, etc., might be constructed. This involves building up a range of microindustrial manufacturing, handling, test, and assembly capabilities (including teleoperators) which would always remain in, and function in, a superfluid liquid helium environment. This avoids problems such as thermal cycling induced stress that plague superconducting technologies such as Josephson junctions. ----------------------------------------------------------------------(27)

VLSI MICRO-CHEMISTRY SYSTEMS For chemical processing systems using DNA, RNA, ribosomes, polymers, enzymes, etc., the intermediate products consist of small numbers of molecules that can be exponentially replicated for the final product if needed. Here, one could use Very Large Scale Integration (VLSI) pattern definition equipment from electrical circuit deposition to deposition of highly miniaturized chemical transport channels, reaction chambers, piezoelectric pumps, electromolecular propulsion (Maugh, 1982), solid state laser (Zewail, 1980) and ultrasonic wave (IRD, 1982) "catalysis" sites, immobilized enzymes, electrophoresis sorters, pH sensors, impedance sensors, etc. , on a chip. These would be extensions of the technology used to put miniaturized gas chromatographs on silicon chips (Angell,
