Very Interesting Knowledge Sharing

I'm seriously into knowledge sharing. Especially for those who find my thought process worthy of public discussion. I find this physics paper quite interesting...

The goal of molecular manufacturing is to build engineerable high-performance products of all sizes, rapidly and inexpensively, with nanoscale features and atomic precision. Molecular manufacturing is the only branch of nanotechnology that intends to combine kilogram-scale products, atomic precision, and engineered programmable structure at all scales. It is no coincidence that molecular manufacturing has gone far beyond other branches of nanotechnology in investigating productive nanosystems, because high-performance nanoscale manufacturing systems are the only way that these goals can be achieved. Building such a product appears to require direct computer control of very small operations. In other words, it needs programmable manufacturing systems capable of acting at the nanoscale. So, you find this interesting? The core of this project is planar assembly: the construction of products by deposition of functional blocks one layer at a time. Planar assembly is a new development in molecular manufacturing theory. It is based on the realization that sub-micron nano-featured blocks are quite convenient for product design as well as manipulation within the nanofactory construction components, and can be deposited quite quickly due to favorable scaling laws. Seriously? The development of planar assembly theory, combined with recent advances in molecular fabrication and synthesis, indicate that it may be time to start a targeted program to develop molecular manufacturing. I hope you have a dictionary with you because I don't think you even understand simple English. Molecular manufacturing emphasizes the use of precise, engineered, computer-controlled, nanoscale tools to construct vast numbers of improved tools as well as products with vast numbers of precise, engineered nanoscale features. It has not been clear how to design and build the first nanoscale tools to start the process of scaleup and improvement, or how easily the operation of many advanced tools could be coordinated. Wouldn't want you to misunderstand, you see... This paper develops a roadmap from today's capabilities to advanced molecular manufacturing systems. A number of design principles and useful techniques for molecular construction via nanoscale machines are discussed. Two approaches are presented to build the first tools with current technology. Incremental improvement from the first tools toward advanced integrated "nanofactories" is explored. So, do you think this molecular thingy bite people? A scalable architecture for an advanced nanofactory is analyzed. The performance of advanced products, and some likely applications, are discussed. Finally, considerations and recommendations for a targeted development program are presented. Are you sure? Would be scary if I were to run into them on the streets. Although most forms of nanotechnology do not pose unfamiliar risks, one advanced field – molecular manufacturing – may present a source of extreme risk due to the implications of the power of its products. Are you still reading? Molecular manufacturing will benefit from multiple advantages that other technologies, including earlier generation nanotechnologies, do not possess. Work toward this form of manufacturing is still in formative stages, but development could rapidly become easier, and it may be achieved with surprising speed once a few basic capabilities are attained. I admire your determination. Rapid, inexpensive, large-scale manufacture of highly advanced products may have several unfortunate consequences, including new classes of WMDs (weapons of mass destruction), unstable arms races, environmental impacts, destructively enabled individuals, social upheaval, and oppressive governance. I'm yawning here... However, the technology is dual-use and also may be highly beneficial. For this and other reasons, patchwork policy solutions will be counterproductive. The goal of molecular manufacturing is to build engineerable high-performance products of all sizes, rapidly and inexpensively, with nanoscale features and atomic precision. Managed to catch a few winks. Molecular manufacturing is the only branch of nanotechnology that intends to combine kilogram-scale products, atomic precision, and engineered programmable structure at all scales. It is no coincidence that molecular manufacturing has gone far beyond other branches of nanotechnology in investigating productive nanosystems, because high-performance nanoscale manufacturing systems are the only way that these goals can be achieved. So, where are we exactly? Building such a product appears to require direct computer control of very small operations. Already? In other words, it needs programmable manufacturing systems capable of acting at the nanoscale. The core of this project is planar assembly: the construction of products by deposition of functional blocks one layer at a time. What will happen if nanoscale were to marry nanoblock? Planar assembly is a new development in molecular manufacturing theory. It is based on the realization that sub-micron nano-featured blocks are quite convenient for product design as well as manipulation within the nanofactory construction components, and can be deposited quite quickly due to favorable scaling laws. Nano nano! Get it? No? Robin Williams? No? The development of planar assembly theory, combined with recent advances in molecular fabrication and synthesis, indicate that it may be time to start a targeted program to develop molecular manufacturing.Molecular manufacturing emphasizes the use of precise, engineered, computer-controlled, nanoscale tools to construct vast numbers of improved tools as well as products with vast numbers of precise, engineered nanoscale features. Sighh... It has not been clear how to design and build the first nanoscale tools to start the process of scaleup and improvement, or how easily the operation of many advanced tools could be coordinated. I should award you with a medal. This paper develops a roadmap from today's capabilities to advanced molecular manufacturing systems. A number of design principles and useful techniques for molecular construction via nanoscale machines are discussed. For sheer determination. Two approaches are presented to build the first tools with current technology. Incremental improvement from the first tools toward advanced integrated "nanofactories" is explored. And a complete waste of time. A scalable architecture for an advanced nanofactory is analyzed. The performance of advanced products, and some likely applications, are discussed. Time for tea! Finally, considerations and recommendations for a targeted development program are presented. Although most forms of nanotechnology do not pose unfamiliar risks, one advanced field – molecular manufacturing – may present a source of extreme risk due to the implications of the power of its products. That was delicious! Still reading? Molecular manufacturing will benefit from multiple advantages that other technologies, including earlier generation nanotechnologies, do not possess. Work toward this form of manufacturing is still in formative stages, but development could rapidly become easier, and it may be achieved with surprising speed once a few basic capabilities are attained. Did you notice I copied and pasted this text twice? Rapid, inexpensive, large-scale manufacture of highly advanced products may have several unfortunate consequences, including new classes of WMDs (weapons of mass destruction), unstable arms races, environmental impacts, destructively enabled individuals, social upheaval, and oppressive governance. I bet you didn't! However, the technology is dual-use and also may be highly beneficial. For this and other reasons, patchwork policy solutions will be counterproductive.

I hope you learned a thing or two!
