A Crash Program
To Create the Fusion Economy

[PDF version of this article]
This is the second in our series of articles from the 21st Century Science and Technology (TCS) Special Report, "Mankind's Thermonuclear Future." Here, TCS calls for an immediate, international, collaborative crash program to achieve controlled thermonuclear-fusion power generation in the short term, along with other ultra-high technology industrial applications of fusion technology. Last week, EIR (Sept. 13) published "The Pacific Development Corridor: Maglev Across the Bering Strait," by Benjamin Deniston.
We have reached the point that not only is man's power to harness the processes of the Sun an emerging reality, it is, in fact, an existential necessity.
We must now direct our creative faculties and physical resources, in an international collaboration reaching from Eurasia to the Americas, toward achieving critical breakthroughs in the domain of thermonuclear processes. This is the long-delayed next step in the willful process of human evolution, illustrated by the previous successive transitions from a wood-based society, to a coal economy, then to petroleum and natural gas, followed by the higher potentials of nuclear fission power.
By increasing what the American economist Lyndon LaRouche has defined as the energy-flux density of the economy, we gain control over processes of higher energy throughput per unit of area, as expressed in a wide range of technologies, infrastructure projects, and production methods. With the fusion economy, energy supplies become relatively limitless, since the fusion fuel contained in one liter of seawater provides as much energy as 300 liters of petroleum.
But this is more than limitless power. The fusion economy brings mankind into the domain of "high-energy-density physics," dealing with thermonuclear reactions and plasmas with energy densities on the order of 1011 joules per cm3a billion times the energy density of the battery in your smart phoneand the dynamic interrelationship among plasmas, lasers, fusion, and antimatter reactions. For example, ultra-high-powered, petawatt lasers are capable of producing extremely brief pulses of laser light 1,000 times as powerful as the energy coursing through the entire U.S. electrical grid.
This new platform brings a wide range of fusion-related technologies and experimental capabilities, from high-powered lasers, to particle accelerators, to high-temperature plasma generators, to directed-energy explosions, all working in a dynamic relationship, complementing each other to transform mankind's entire economic system, eliminating any concerns over limited power or limited resources. Given the crises both in the United States and globally, this is an absolute necessity, and requires a global crash program, comparable to the Manhattan Project or the Apollo Program, but on an international scale (see box).
Full transformation will take some time, but certain fusion technologies can provide economic benefits in the relatively short term.
Already at the beginning of the fusion age, such visionaries as the co-founder of Lawrence Livermore National Laboratory and leading proponent of the Strategic Defense Initiative (SDI), Dr. Edward Teller, supported the utilization of the immense energy-density made available with fusion reactions, in the form of Peaceful Nuclear Explosions (PNEs). It was demonstrated that this could revolutionize canal building, port construction, mining, aquifer creation, tunneling and other requirements of bulk earth moving. Today, PNE technology can be improved and applied for rapidly accelerating and cheapening the construction of vital projects, such as NAWAPA XXI.
For materials processing and natural resources, the plasma torch, operating at temperatures below that required for fusion, can break down and separate many materials into their constituent elements and isotopes, meaning that chemical and nuclear "waste" can be processed into valuable resources. Such plasma torches can be a driver toward the higher densities of power achievable with a self-sustaining fusion reaction, at which point we could theoretically extract many times the current annual U.S. production of iron, copper, aluminum, and many other resources from virtually any cubic mile of dirt, and reprocess the valuable concentrations of materials in landfills.
Beyond separation and concentration of resources, a fusion economy allows for the creation of completely new materials with new properties, and even the transmutation of one element into another. For example, petawatt lasers have already demonstrated the ability to transform gold into platinum, and future transmutation potentials are much broader. Thus, the fusion economy demonstrates beyond a doubt that, for an advancing mankind, there are no limited resources, and no limits to growth.
While the broad-based implementation of some of these systems will require a generation or more of work, their future realization depends on getting started now, and the first steps of a fusion economy are closer than you may think.
1. A Call for an International Manhattan Project
The slow progress in developing fusion power over the past four decades has been the result of political decisions, not scientific impossibilities. For example, in 1980, the U.S. Congress passed Rep. Michael McCormack's "Magnetic Fusion Energy Engineering Act," calling for a crash investment in fusion, and for the construction of a prototype magnetic-confinement fusion reactor by the year 2000. However, the breakthroughs were never made because the program was simply never funded, as is indicated in the following graph of the annual fusion budget.
Thus, the challenge today is as much political as scientific. The decision must be made to develop the fusion economy; with this commitment, and with full funding and support of key governments, an international crash effort can make this a reality (Figure 1).
Fusion scientists from around the world (and especially the remaining veterans of the fusion efforts going back to the 1960s) must be pulled together to properly plan a serious crash program. The purpose of such a scientific gathering is clear: Move the accountants out of the room; get the bureaucracy out of the way; and let the scientists hammer out what must be done from a scientific standpoint. No options should be off the table, including the revival of alternative fusion-reactor designs which were shelved for political or budgetary reasons.
With the scientific, technical, and engineering considerations placed clearly on the table, a crash program can begin, pulling together the fusion and high-technology resources of the United States, Russia, China, Japan, South Korea, the nations of Europe, and other countries, along with support from existing bodies such as the International Atomic Energy Agency (IAEA).
While this new crash program is being developed and implemented, an array of existing fusion programs can be fully supported and accelerated, including the large international project, the International Thermonuclear Experimental Reactor (ITER), which has been delayed because of lack of funding and poor coordination.
In the United States, greatly increased funding must be supplied to domestic fusion programs, reversing the Obama Administration's slashing of the fusion budget. This includes saving the Alcator C-Mod research facility at MIT (the largest U.S. training facility for students studying fusion) and funding the expansion of the ongoing fusion research at the nation's various national labs, universities, and industries.
Other nations can do the same, as with the advanced work going in China with their Experimental Advanced Superconducting Tokamak (EAST), in South Korea with the Superconducting Tokamak Reactor (K-STAR), and the joint Russian-Italian IGNITOR project, among others.
These are only a few examples of ongoing work. A full survey of currently existing programs and past proposals must be done from the standpoint of an open-ended international crash program effort. This will lead to a selection of new demonstration and experimental systems to be constructed (Table 1).
While effectively unlimited electricity is critical to the future, it is not the only benefit of a fusion economy. The international crash program will also focus on the applications of the great energy densities and unique physical properties of the fusion process, as applied to materials processing, industry, and manufacturing, for example. Put simply, a fusion economy completely revolutionizes man's relationship to the Periodic Table of elements, and what are considered "natural resources."
2. Fusion Technology for Production and Industry
With fusion, we will be able to create plasmas at temperatures of tens and hundreds of millions of degrees. At these temperatures, any known substance can be easily broken down into its constituent elements. However, even low-temperature plasmas (tens of thousands of degrees) are already in use in certain industries today, and their use must be expanded. For example, so-called "arc plasmas" are used in welding and in specialty steelmaking, and a plasma separation process has been used to isolate desired isotopes for medical and other purposes. While these lower-temperature plasmas do not exhibit the full potential of what we will be able to achieve with a fusion reactor, they show the promise of what is to come, when man has full access to controlled thermonuclear processes as the basis of his economic platform.
Continuing to broaden our use of plasma technologies today will serve to
- improve our knowledge of plasmas in general,
- aid in the development of technologies to handle them and put them to work,
- train a new generation of scientists and industrial workers in the use of plasmas and fusion-related technologies, and
- produce specialty materials which could overcome materials challenges arising in fusion research, such that the advances in productivity made today will contribute to accelerating the realization of fusion.
2.1 The Fusion Torch
The "fusion torch" design, first proposed in 1969 by Bernard Eastlund and William Gough of the U.S. Atomic Energy Commission, uses an ultra-high-temperature fusion plasma, diverted from a fusion reactor core, to reduce virtually any feedstock (low-grade ore, fission byproducts, seawater, garbage from landfills, etc.) to its constituent elements. Once the feedstock has been injected into the plasma, the elements become dissociated into electrons and ions, and the desired elements (or isotopes) can be separated from one another by atomic number or atomic mass, creating pure, newly synthesized mineral "deposits" from virtually any substance (Figure 2).
To make the point, an average cubic mile of dirt contains approximately 200 times the amount of annual U.S. aluminum production, 8 times the iron production, 100 times the tin, and 6 times the zinc, though most of it is not in a concentrated form, making it impossible to effectively mine and process with current technologies. Even with the fusion torch, we will likely not need to mine random plots of dirt, but this indicates how extensive the available resources are when we move to more energy-dense processing techniques. Lower-grade ores and lower concentrations (which are currently useless to us) will suddenly become readily available resources. Dirt becomes ore. Scrap materials which already contain concentrated elements, can also be efficiently reprocessed as new, vital raw materials. Urban landfills, containing disorganized forms of most all the elements we already use, become one of the most potentially valuable concentrations of materials waiting to be processed. According to Eastlund and Gough, with the wide availability of commercial fusion, the fusion torch will become an efficient method of generating whatever bulk raw materials are necessary to meet humanity's industrial and other needs.
Even before mastering a self-sustaining fusion reaction, a high-temperature plasma torch can be created with today's technology. By the 1980s the company TRW had patented and was promoting the commercial construction of a plasma torch design fully capable of processing spent nuclear fission fuel, and retrieving valuable isotopes. Already then, what some still today call "nuclear waste" or "chemical waste" had become a potential resource, with the application of the available processing technologies.
Beyond accessing existing resources, the ability to select and harvest very specific ratios of isotopes and elements in substantial quantities creates the potential for a revolution in the qualities and properties of materials. For example, specialty steel can be isotopically tuned, improving the capabilities for handling high-energy processes, ranging from industry, to fusion reactors, to space travel.
Claims of crises caused by "limited resources" fly out the window with the fusion torch and a fusion economy.
2.2 Chemicals Processing
Another use for the fusion torch design will be the transformation of the energy from the plasma into a radiation field for processing industrial materials and chemicals.
By injecting selected "seed" materials into the fusion torch, the emission frequency and intensity of the radiation can be finely modulated by the amount and type of materials chosen. With a fusion plasma, as opposed to lower-temperature plasmas, it is possible to maximize the energy within specified, narrow bands of the spectrum. This radiation can then be transmitted through a "window" material to a fluid or other body. Because the frequency of the radiation can be tuned to the material being processed, the existing limitation placed on bulk processing by the limits of surface heat transfer is greatly overcome. For example, ultraviolet radiation could be generated to sterilize industrial process water and drinking water.
The neutrons from the fusion reaction can be used for direct or indirect heating of process materials to temperatures ranging from 1,000°C to more than 3,000°C. They can also be used themselves, or converted via a blanket material into high-energy gamma rays, for catalyzing chemical reactions, thus directly converting the fusion energy into chemical energy. This could greatly increase the efficiency of the production of industrial chemicals requiring high heats or high activation energies, such as hydrogen, ozone, carbon monoxide, and formic acid. This increased power over materials and chemicals processing opens up a scale of production never before possible.
With the use of high-temperature plasmas the quality and quantity of available resources is completely transformed. Eastlund and Gough said in 1969, "the vision is there; its attainment does not appear to be blocked by nature. Its achievement will depend on the will and the desire of men to see that it is brought about."
3. Magnetohydrodynamics (MHD)
For Direct Conversion
For the generation of electricity from fusion power, we will have to revive and advance the science of magnetohydrodynamics (MHD), a technology which can be used with virtually any source of energy to generate electricity directly from a high-temperature plasma. As a "direct conversion" process, it eliminates the need for large steam turbines, and has the potential to double the amount of electric power generated from every unit of fuel used.
While in the 1980s, some of the basic technologies were under development in the United States, with coal-powered systems; in the USSR, with natural-gas-based systems; and in Japan, using petroleum, the ultimate goal is the application to fusion-power generation, with a possible role for utilization in fission-power systems along the way.
The basic principle in MHD conversion is to pass a high-temperature plasma through a magnetic field. The magnetic field creates an electrical current in the plasma, which is drawn off by electrodes along the length of the channel through which the plasma flows. There are essentially no moving parts, since the plasma is itself moving through the magnetic field (Figure 3).
In a standard power plant (coal or nuclear), only 30% to 40% of the energy released by the fuel gets converted into electricity through the heating of steam used to spin a turbine, while the rest of the energy is lost as "waste heat" (this is the efficiency of the power plant).
In basic MHD systems, the direct conversion can nearly double the electricity generated without changing the amount of fuel, with the 50% efficiencies of simple MHD systems. Adding a steam turbine (to take advantage of the remaining heat) can increase the efficiency to 60%.
These are more than theoretical concepts: In the late 1970s, researchers at Argonne National Laboratory succeeded in achieving 60% efficiency with a nuclear fission-powered MHD system, and the experimenters were confident they could reach 80% with future developments.
However, despite these exciting studies and results, serious MHD direct conversion research basically ended in the 1980s (along with many other areas of promising research).
MHD must be revived for the generation of power with fusion (with the possible application for more efficient fission systems as well). Using advanced fusion fuels, such as deuterium and helium-3, in a magnetically confined system, the charged particles of the fusion product can be continuously run through a magnetic field to directly generate electricity at efficiencies of 70%.
4. Plowshare and Engineering
With Nuclear Explosions
An important and relatively short-term application of thermonuclear power is the use of peaceful nuclear explosions (PNEs) for construction, the general precedent for which has already been well established by the 1960s-'70s U.S. Plowshare Program, which took its name from the Book of Isaiah: "And he shall judge among the nations, and shall rebuke many people: and they shall beat their swords into plowshares, and their spears into pruning hooks: nation shall not lift up sword against nation, neither shall they learn war any more."
Although detailed plans for their application in the construction of the NAWAPA project are not known to the authors of this report, in 1968, Ralph M. Parsons (founder of the company which originally designed NAWAPA) did raise the general possibility of using nuclear explosives for its construction, in a letter to a leading proponent of the project at the time, Sen. Frank Moss.
Today such considerations must again be put up front, to fast-track the construction of NAWAPA XXI and similar projects.
To bring some of the abundant northern waters down into the water-starved regions of the continent (from the Mississippi River to the Pacific Coast, and from the Canadian Prairies to Northern Mexico), NAWAPA XXI requires that an immense amount of earth be moved, totalling some 725 billion cubic feet (about 5 cubic miles), including 39 tunnels (totalling 1,200 miles) and 5,400 miles of canals. PNEs could be used for the construction of these new tunnels and canals, for widening or deepening existing rivers and reservoirs involved in the system, and even for the construction of new deep-water ports, if needed.
Peaceful nuclear and thermonuclear explosions can be used to sculpt terrains on scales difficult or impossible with conventional methods, dramatically decreasing both the construction time, and the physical costs, based on the higher energy density unique to nuclear and thermonuclear reactions.
For example, according to the 1960s Atomic Energy Commission's informational videos on Plowshare, a 10-kiloton nuclear explosive could, at the time, be as small as a cylinder 3 feet long and 15 inches in diameter. To release an equivalent amount of energy from conventional explosives would require 10,000 tons of TNT (hence the "10 kiloton" measure of the yield of the nuclear explosive), which would form a cylinder 200 feet long and 36 feet in diameterequivalent to comparing the size of about 36 semi-trucks to the size of your chair.
Over two decades, Project Plowshare completed 27 test nuclear explosions, and proposed using the technique for projects ranging from an artificial harbor at Cape Thompson, Alaska, to a new, sea-level Panama Canal, where studies showed that the excavation costs could be reduced by up to an order of magnitude with the usage of PNEs. This reflected the general optimism of the "Atoms for Peace" outlook outlined by the Eisenhower Administration and promoted by President Kennedy.
While the official U.S. program ended in the 1970s, the concept has continued to be discussed and considered. For example, another well-known case for the use of PNEs is a project which currently has renewed momentum: the construction of the Kra Canal across Thailand, providing an alternative to the congested Strait of Malacca (see box). While also designed for construction with conventional methods, this project attracted the interest of scientists at Lawrence Livermore National Lab for the application of PNEs. In fact, to dispel unjustified fears of radiation release, Lawrence Livermore scientist Dr. Edward Teller promised that he would move his family to Thailand after the construction of the Kra Canal, if they built it with PNEs.
While the original Plowshare tests were dealing with the very early stages of nuclear and thermonuclear technology, the tests allowed them to figure out how to contain the radiation released from the explosions, and by the end of the program the scientists were confident that the most dangerous safety hazards posed by PNEs would be the same as in any conventional explosionthe groundshock, air blast, dust cloud, etc.and not the radiation.
If a PNE program is restarted today, the development of newer technologies can guarantee that the radiation issue will pose no problem whatsoever.
This includes the prospect of "non-nuclear triggers" for thermonuclear explosions. Currently, fusion explosions require a fission reaction to trigger the fusion, meaning the fission products are involved in the explosion (although they can be contained). However, other methods can trigger fusion reactions as well, including inertial confinement (as with lasers, for example) or even small amounts of antimatter.
Fulfilling the Thermonuclear Age
The fusion economy is not just a new way of acquiring power to be applied to the existing economy.
The entire history of the development of humanity has been characterized by the creation of new economic systems, with new resource bases, and new technological capabilitiesa series of qualitative changes driven by increasing levels of controlled energy-flux density. This is one of the purest expressions of the unique creative powers that separate mankind from any mere animal species.
The greatest economic revolutions have been driven by transitions to qualitatively higher levels of power sources. Fusion is now the imperative for mankind. By starting now, over the course of the next two generations the power and resource requirements of a growing world population can be met, and mankind can be set on a new path, one actually befitting our true, creative nature.

 The absorption depth of ultraviolet radiation in water is about 1 meter. With the fusion plasma torch, energy fluxes of ultraviolet radiation on the scale of megawatts per m2 can be generated and transferred to the water with very little loss, thus permitting a scale of bulk processing not possible before.

 In a May 10, 1968 letter to Sen. Frank Moss, discussing NAWAPA, Ralph Parsons said, "In the past five years great advances have taken place in tunneling, for example, in earth moving, and in transmission of electric power. One construction factor which could very drastically change both the design and economic basis is the prospect of using nuclear explosives to create deep artificial aquifers for both storage and transfer underground." This was five years after the original NAWAPA design was proposed by the Parsons Company.

 President Kennedy appointed Leland Haworth to the Atomic Energy Commission in 1961. An avid proponent of Project Plowshare, Haworth studied the proposal for a harbor in Alaska, "Project Chariot," in July 1961. In March 1962, Kennedy requested the AEC, to "take a new and hard look at the role of nuclear power in our economy," and Haworth led the writing of the report "Civilian Nuclear PowerA Report to the President1962." In 1963, Kennedy asked Haworth to direct the National Science Foundation.
 Unlike fusion, which creates a very limited number of products, almost none of which are directly radioactive, fission creates nearly all the isotopes of the Periodic Table.
