GeSp2167 MEGABRIDGES by J. E. D. Cline 920503 PURPOSE OF THIS LIBRARY FILE Explore the benefits of initiating a KESTS Technology program. KESTS Technology R&D hasn't begun yet! A fresh look at its potentials here hopefully may stimulate action to begin serious R&D on it, instead of waiting for someone else to do it. DEFINITION KESTS = Kinetic Energy Supported Transportation Structure POTENTIALS CREATED BY KESTS TECHNOLOGY There are potential applications that would have unmatched ability to help both mankind and earth's ecosystem. The technology has the potential of bridging really vast distances, which means the transportion of resources to where needed, such as the bringing of glacial water to desert farm areas, and transporting coal from the mine to the consuming powerplants far away; also incredibly means the potential for opening up GEO for construction of vast living habitats enough for far more than the whole earth's population... enabling continued expansion of civilization and populations while taking the load off of the earth surface ecosystem; also means meaningful work for vast numbers of people going for greatly improved standards of living. Thus it also means a powerful positive alternative to the threat of forced severe population and economic controls imposed worldwide. WHAT ARE KESTS Kinetic Energy Supported Transportation Structures basically would be long tubular structures that are supported by the tremendous kinetic energy of streams of hurtling objects circulating within them. They have a curved shape, much like the shallow curve formed by the path of a baseball thrown by the pitcher to a catcher's mitt, returned by the catcher to the pitcher, back and forth continuously, forming a curved arc between them. WHAT KESTS PERHAPS COULD DO These structures could be used for transporting people and goods between places very far apart, and also for storing and transfering electrical power around its loop length. HOW KESTS WOULD WORK The basic technology would create extremely long structures in which energy is stored in the form of circulating streams of fast moving objects. The structures have had all the air removed from inside them, so the stream of objects can move at speeds of thousands of miles per hour without air's interference. The objects move almost in free-fall at orbital velocities within their long, gently curving tubular structures. They are electromagnetically exchanging their kinetic energy at a low rate only with specific things: the mass stream accellerators, the electrical power extractors (decellerators), the enclosing structure, the "benders" of stream direction, and the vehicles moving along the structure. The speed of the mass stream is changed electromagnetically, much as an ordinary dc motor is sped up or slowed. Some of the energy in the stream is used to support the container's structural weight. More of that energy is used to move payloads along the surface of the container. POTENTIAL APPLICATIONS The technology could create extremely long structures which are far beyond that which is possible using the ordinary strength of materials, since the circulating energy within the structure is what supports the structure. Some examples are: * Pipeline support for piping glacial water to desert areas. * Single span bridges hundreds of miles long. * Ore and coal transport from mine site to processing sites. * Direct transportation between distant cities and suburbs. * Very tall radio towers for the plains states. * Intercontinental single-span bridges within the equatorial belt. * Direct connection between the surface of the earth and space. * Direct support of low earth orbit altitude launch platforms. * Direct connections possible as far as the Clarke Belt, 22,300 mi. * and KESTS on the Moon and Mars could improve access to/from them. The technology could store enormous amounts of energy, accessed electrically, and be used to smooth out the supply and demand fluctuations in commercial electrical power. The technology could move energy from place to place. Since the energy storage involves very high velocity circulating streams of energy, the containing structures can be very large. The electrical energy can be input at one place and extracted for use from another place along the structure. There are potential applications of this technology that utilize all of these capabilities. One extremely important megaproject application would have the circulating structure range from the surface of the earth out to earth synchronous orbit and back. This could enable an astonishing opportunity for humanity, the opening up of a potentially vast unique new real estate. In more detail it has potential for: * Storing enormous energy along its length * Provide connection to space-located solar electric powerplants * Be the transportation link between those powerplants and earth * Bring solar electric power to earth surface electrical grids * Be a bridge from earth surface to GEO materials processing * Provide the power for payload vehicles moving along itself * As a bridge for a railway between earth surface and earth synchronous orbit (known as "GEO" and the "Clarke Belt"), efficiently moving materials to that high place for building the spacecraft and construction gear to go to the Moon as a major resource for raw materials for building vast space settlements back in the Clarke Belt high above the earth's equator g * Be a bridge from earth surface to vast GEO space settlements which then could be built in earth synchronous orbit, relatively stationary compared to the earth's surface AN OLD SPACE SETTLEMENT DESIGN, FOR A NEW PLACE TO LIVE IN SPACE The major detailed design of the assocoated kind of space settlement was done back in 1976 by a NASA study group. Back when the reality was fresh in people's minds, of people traveling to the Moon, exploring while the proud eyes of earthbound people watched, and bringing samples of raw materials back to here on Earth. The structure of these space settlements was to be built entirely from raw materials brought from the moon, launched from there to special areas in space known as L4 and L5, places which are the same distance from the earth as the moon, and form the points of an equal sided triangle, the moon being the third point, and the earth being at the center of this imaginary triangle. The space settlements built of raw material brought from the moon were designed to be home for 10,000 people each. Half of their internal area was devoted to agriculture to feed them well. The other half was residential, commercial and light industrial. The sense of gravity was created by putting a slow spin on the huge wheel-like settlement structure. The typical residence was to be like a townhouse built on a hillside on one side of a valley 600 feet across, with plenty of grass areas and trees, and an artificial stream going down the center of the valley. This valley, of course, gently curved upward in each direction, as it went around inside the mammoth wheel. The outer shielding mass did not rotate, and was the netted mass of the slag left over from the refining processes that made the aluminum, iron and titanium sections from which the main structure was built. The new thing here is that the KESTS make it possible to build some of the huge space settlements nearer earth in GEO, only 10% as far from the earth surface as is L4 and L5, without waiting for the moon to be outfitted with mining and launching equipment. The massive transportaion capability of the KESTS probably would make it feasable to build the first several of the 10,000 person space settlements out of prefab sections built on th earth surface, and then hauled up the KESTS to synchronous orbit. The space settlement design could be more easily perfected with daily direct access to the earth surface. And from an associated spaceport there in orbit with these settlements, a robust return to the moon could occur. Then the lunar ores could be gathered and transported for construction of more of the space settlements in GEO. And there is room for 1.5 million of these space settlements in each ring of them around the earth in GEO...at 10,000 people each, that is high living for 15 billion people, far more than the present entire population of the earth. KESTS has the potential to make this possible. Too far in the future? Perhaps not nearly as far as one might think. For example, examining the previous plan for building such space settlements out in L4 and L5, it was to have taken 22 years from when started until when the first one were to be occupied. Starting then in 1976, 22 years from then would be 1998, just 6 years from now. And that was doing it the hard way, building launchers and mines on the moon first, and sending the material far to L4 and L5 for entirely fabricating the structure there in space the hard way right from the beginning. The first one would have been ready for occupancy a mere 6 years from now if we had started it back then in 1976. And like the combination of KESTS and this ring of space settlements in synchronous orbit, the earlier plan was also to be funded from selling clean electrical power derived from the endless solar power out there in space. The sooner the development of KESTS technology gets started, the quicker they will be available for use. The presense of the KESTS between earth surface and earth synchronous orbit could make the first occupancy of a 10,000 person space settlement much quicker, since it could bring up the prefab materials directly for building the first settlement right there at its high point, relatively motionless over the equator. THE HUMAN ELEMENT There are social/psychological requirements for the synergistic cooperation so necessary for long term survival in such a delicately balanced system. Very consistent individuals as well as very creative individuals are needed to keep it all running and cope with new challenges, and provide a high standard of living for all. An essential aspect of creating the KESTS and associated ring of space settlements is to create and populate them with people who are fully functional, well balanced human beings who are having all their needs fulfilled in the process, including such uniquely human needs as a satisfactory love life for everyone. FUNCTIONAL RELIABILITY Reliability of the technology is of extreme importance. They will need to function indefinitely, once people depend on them. So research needs to focus on which kinds of KESTS technologies potentially have extreme long term reliability. A goal might be to make the reliability equivalent to that of a heat pipe. A heat pipe is a sealed tube which transports heat from one end to the other end by vaporizing fluid in itself at its hot end, and condensing the resulting vapors back to liquid at the cold end. The liquid runs downward back to the hot end, maintaining the circulation. Such a sealed system with functional long term reliability needs to be a developmental goal of KESTS technologies. KESTS technologies which have only short term reliability have applications, too: * Emergency bridges for rescue or emergency supply activities * Creating the temporary "falsework" upon which is built a high reliability KESTS along the same path. * Temporary demonstration of the potentials of KESTS A conventional bridge, once built, needs little attention except for anticorrosive painting. Although the KESTS bridges similarly are essentially stationary structures, they require the control complexity of a jet airliner and power plant. Constant monitoring of wind loads pushing against the side of the KESTS, and shifting moving payloads along the lenght of the KESTS, require constant compensatory tiny shifts in the velocity direction of the stream as it exits the re-accellerator. PUTTING IT UP IN THE FIRST PLACE Emplacement of KESTS is a major challenge, like building any bridge. What is to support the sections of the structure while it is being built? Only another KESTS has the span and strength for this task. The temporary form of KESTS needs to get emplaced itself first, of course. One way is to launch a non-enclosed temporary KESTS built like a linear turbine engine, something analogous to how a linear electrical motor is like an unrolled ordinary electrical motor, so analogously would this form of KEST be launched by a chemical rocket engine's exhaust push against a chain of buckets thusly being accellerated meteorically upward, like an "unrolled" jet turbine engine. Once a circulating loop is formed by this very inefficient KESTS, and maintained by continued added energy at earth surface contact points by continued chemical engine power or by steam pushing against the stream of buckets, this could be the "falsework" upon which a true KESTS could be built and accellerated up to self-supporting speed. Another possibility is by using an unbalanced force at the upward end of a very small diameter flexible KESTS which perhaps could raise and direct itself upward to eventually define the circulating path of the larger more permanent KEST to be built. SOME RELATED MATH There are some general mathematical principles which apply to KESTS. One is that the kinetic energy of any one of the objects in the hurtling stream inside the KESTS is one-half of the mass of the object times the velocity of the object again times tho velocity of the object (Ek=.5*m*v*v). Another is that the total energy contained within a KESTS is the rate of energy flow at the output of the re-accellerator times the length of the KESTS. Another is that the energy needed to be input to the re-accellerator(s) is the sum of the energy needed to support the weight of the tubular shell, the energy used to support the weight of the stream benders, the energy needed to power the vehicles moving payload along the structure, and the energy that is drawn out at another location along the KESTS, all divided by the efficiency of the accellerator(s). SOME OTHER PRINCIPLES INVOLVED The weight of the mass stream itself does not need energy to be supported, since its considerable mass is essentially coasting in free-fall and does not additional energy to support it once it has been accellerated to its correct velocity. The energy of each piece of the mass stream is continually excahnging between the kinetic energy of high velocity and the potential energy of altitude above the earth surface, so this means the speed of the components of the mass stream near it top is significantly slower than that speeding past the earth surface contact point(s); since the actual number of mass stream components passing any given part of the KESTS loop is constant, this means they are closer together at the top than at the bottom of the loop. And there are actually at least two laterally-connected tubes with mass streams flowing within them around the loop, because support of the weight of the tube can only be done by electromagnetically dragging against it by an upward-direction moving mass stream, so there needs to be an upward portion of the mass stream on both sides of the KESTS, speaking of one of the kind which does a loop all around the planet and extends out to GEO at one point. Undoubtably, serious R&D on KESTS Technology would produce real working systems that differ in many ways from that envisioned here. In a dozen years of so, the idea of KESTS may have faded from knowledge; or perhaps someone looking down at a KESTS tube from a prototype space settlement, and muse that this 1992 file resembles reality reminiscent to the following item on electricity: This is transcribed from an ad received at a WESCON, by the T.

That is, if we choose to do it, if we start soon, if we somehow resume our high rate of technological competancy and advancment, and if it all pans out. The concepts are perhaps still too vague and undefined to be a launching point for serious action by the scientific and industrial powers. But let's consider the lecture advertisement of 1752, and yet also notice the electrical and electronic technology around us, electric lights, telephones, circulating fans, elevators, household appliances, digital watches, computers, color television and stereo Walkmans: they are real, useful, and essential parts of our daliy lives. The almost incredible potentials represented by Kinetic Energy Supported Transportation Structures, especially that of the possibility of them enabling the heavy weight of the massive human civilization to move to earth synchronous orbit within most of our lifetimes, and thus allowing the restoration of a naturally balanced earth surface ecosystem, seem at least worthy of real immediate attention.
