  • Thermonuclear AB-Reactors for Aerospace
    1 Article Micro Thermonuclear Reactor after Ct 9 18 06 AIAA-2006-8104 Micro -Thermonuclear AB-Reactors for Aerospace* Alexander Bolonkin C&R, 1310 Avenue R, #F-6, Brooklyn, NY 11229, USA T/F 718-339-4563, [email protected], [email protected], http://Bolonkin.narod.ru Abstract About fifty years ago, scientists conducted R&D of a thermonuclear reactor that promises a true revolution in the energy industry and, especially, in aerospace. Using such a reactor, aircraft could undertake flights of very long distance and for extended periods and that, of course, decreases a significant cost of aerial transportation, allowing the saving of ever-more expensive imported oil-based fuels. (As of mid-2006, the USA’s DoD has a program to make aircraft fuel from domestic natural gas sources.) The temperature and pressure required for any particular fuel to fuse is known as the Lawson criterion L. Lawson criterion relates to plasma production temperature, plasma density and time. The thermonuclear reaction is realised when L > 1014. There are two main methods of nuclear fusion: inertial confinement fusion (ICF) and magnetic confinement fusion (MCF). Existing thermonuclear reactors are very complex, expensive, large, and heavy. They cannot achieve the Lawson criterion. The author offers several innovations that he first suggested publicly early in 1983 for the AB multi- reflex engine, space propulsion, getting energy from plasma, etc. (see: A. Bolonkin, Non-Rocket Space Launch and Flight, Elsevier, London, 2006, Chapters 12, 3A). It is the micro-thermonuclear AB- Reactors. That is new micro-thermonuclear reactor with very small fuel pellet that uses plasma confinement generated by multi-reflection of laser beam or its own magnetic field.

    1 Inexpensive Mini Thermonuclear Reactor By Alexander Bolonkin [email protected] New York, April 2012 2 Article Thermonuclear Reactor 1 26 13 Inexpensive Mini Thermonuclear Reactor By Alexander Bolonkin C&R Co., [email protected] Abstract This proposed design for a mini thermonuclear reactor uses a method based upon a series of important innovations. A cumulative explosion presses a capsule with nuclear fuel up to 100 thousands of atmospheres, the explosive electric generator heats the capsule/pellet up to 100 million degrees and a special capsule and a special cover which keeps these pressure and temperature in capsule up to 0.001 sec. which is sufficient for Lawson criteria for ignition of thermonuclear fuel. Major advantages of these reactors/bombs is its very low cost, dimension, weight and easy production, which does not require a complex industry. The mini thermonuclear bomb can be delivered as a shell by conventional gun (from 155 mm), small civil aircraft, boat or even by an individual. The same method may be used for thermonuclear engine for electric energy plants, ships, aircrafts, tracks and rockets. ----------------------------------------------------------------------- Key words: Thermonuclear mini bomb, thermonuclear reactor, nuclear energy, nuclear engine, nuclear space propulsion. Introduction It is common knowledge that thermonuclear bombs are extremely powerful but very expensive and difficult to produce as it requires a conventional nuclear bomb for ignition. In stark contrast, the Mini Thermonuclear Bomb is very inexpensive. Moreover, in contrast to conventional dangerous radioactive or neutron bombs which generates enormous power, the Mini Thermonuclear Bomb does not have gamma or neutron radiation which, in effect, makes it a ―clean‖ bomb having only the flash and shock wave of a conventional explosive but much more powerful (from 1 ton of TNT and more, for example 100 tons).

Fomitchev-Zamilov Quantum Potential Corporation, 200 Innovation Blvd, Suite 254, State College, PA 16803 e-mail: [email protected] Cavitation-induced fusion (also known as bubble fusion or sonofusion) has been a topic of much debate and controversy and is generally (albeit incorrectly) perceived as unworkable. In this paper we present the theoretical foundations of cavitation-induced fusion and summarize the experimental results of the research conducted in the past 20 years. Based on the systematic study of all available data we conclude that the cavitation-induced fusion is feasible, doable, and can be used for commercial power generation.

  • Cold Fusion Again 1 Introduction
    Prespacetime Journal j February 2016 j Volume 7 j Issue 2 j pp. 379-396 379 Pitk¨anen,M., Cold Fusion Again Exploration Cold Fusion Again Matti Pitk¨anen 1 Abstract During years I have developed two models of cold fusion and in this article these models are combined together. The basic idea of TGD based model of cold is that cold fusion occurs in two steps. First dark nuclei (large heff = n × h) with much lower binding energy than ordinary nuclei are formed at magnetic flux tubes possibly carrying monopole flux. These nuclei can leak out the system along magnetic flux tubes. Under some circumstances these dark nuclei can transform to ordinary nuclei and give rise to detectable fusion products. An essential additional condition is that the dark protons can decay to neutrons rapidly enough by exchanges of dark weak bosons effectively massless below atomic length scale. Also beta decays in which dark W boson decays to dark electron and neutrino can be considered. This allows to overcome the Coulomb wall and explains why final state nuclei are stable and the decay to ordinary nuclei does not yield only protons. Thus it seems that this model combined with the TGD variant of Widom-Larsen model could explain nicely the existing data. In this chapter I will describe the steps leading to the TGD inspired model for cold fusion combining the earlier TGD variant of Widom-Larsen modelwith the model inspired by the TGD inspired model of Pollack's fourth phase of water using as input data findings from laser pulse induced cold fusion discovered by Leif Holmlid and collaborators.

    Looking Back at Half a Century of Fusion Research P. STOTT Association Euratom-CEA, Centre de Cadarache, 13108 Saint Paul lez Durance, France. This article gives a short overview of the origins of nuclear fusion and of its development as a potential source of terrestrial energy. 1 Introduction A hundred years ago, at the dawn of the twentieth century, physicists did not understand the source of the Sun‘s energy. Although classical physics had made major advances during the nineteenth century and many people thought that there was little of the physical sciences left to be discovered, they could not explain how the Sun could continue to radiate energy, apparently indefinitely. The law of energy conservation required that there must be an internal energy source equal to that radiated from the Sun‘s surface but the only substantial sources of energy known at that time were wood or coal. The mass of the Sun and the rate at which it radiated energy were known and it was easy to show that if the Sun had started off as a solid lump of coal it would have burnt out in a few thousand years. It was clear that this was much too shortœœthe Sun had to be older than the Earth and, although there was much controversy about the age of the Earth, it was clear that it had to be older than a few thousand years. The realization that the source of energy in the Sun and stars is due to nuclear fusion followed three main steps in the development of science.

  • Chemistry Casts Doubt on Bubble Reactions
    From the Science newsroom More News Posted 24 July, 5 pm PST Chemistry Casts Doubt on Bubble APNet Reactions Home A controversial claim that scientists had detected signs of fusion in a rapidly collapsing bubble may have further imploded this week. A new experiment that measures the energy budget of a collapsing bubble for the first time indicates that so-called "bubble fusion" is unlikely to occur. The controversy involves a peculiar phenomenon known as Encyclopedia of sonoluminescence. If liquid is zapped with sound waves in the Biodiversity right manner, it will "crack," creating bubbles that contract so Online violently that they glow with light. Earlier this year, Science Journals published the results of such an experiment by engineer Rusi Taleyarkhan of Oak Ridge National Laboratory in Tennessee and five colleagues. The group reported the detection of neutrons that they argued were generated by a fusion reaction inside a sonoluminescing bubble. The claim was greeted with skepticism even before it was published (Science, 8 March, pp. 1808 and 1868). Now two scientists have taken a close look at whether enough energy is available in an imploding bubble for fusion. Kenneth Suslick and Yuri Didenko, sonochemists at the University of Illinois, Urbana-Champaign, used fluorescent dyes to measure Book the byproducts of sonoluminescence in water. From the Catalog concentrations of these molecules created by different single- Concise Encyclopedia of bubble sonoluminescence experiments, Suslick and Didenko the Ethics of New figured out the conditions that led to those reactions--and Technologies where the energy goes when the bubble collapses. Most of the energy is dissipated by chemical reactions, Suslick reports in the 25 July issue of Nature, noting that the experiment roughly matches theorists' expectations.

    +44 20 8123 2220 [email protected] Analyzing Fusion Energy 2017 https://marketpublishers.com/r/AAF7C2E2BB4EN.html Date: March 2017 Pages: 185 Price: US$ 850.00 (Single User License) ID: AAF7C2E2BB4EN Abstracts Fusion power is the power generated by nuclear fusion reactions. In this kind of reaction, two light atomic nuclei fuse together to form a heavier nucleus and in doing so, release a large amount of energy. In a more general sense, the term can also refer to the production of net usable power from a fusion source, similar to the usage of the term "steam power." Most design studies for fusion power plants involve using the fusion reactions to create heat, which is then used to operate a steam turbine, which drives generators to produce electricity. Except for the use of a thermonuclear heat source, this is similar to most coal, oil, and gas-fired power stations as well as fission-driven nuclear power stations. Aruvian Research brings a research report on the lucrative field of fusion energy – Analyzing Fusion Energy 2017. The research report takes a look at the importance of fusion power in an era where the usage of renewable energy has become a norm. The report begins with an analysis of the basics of fusion energy, the various stages of development in fusion power, the magnetic concept, the Z-pinch concept, inertial confinement concept and many others. The role of tokamaks are analyzed in the report, along with the physics of fusion reactors. The concept of plasma heating is analyzed so as to provide a better understanding of fusion power.

  • Theoretical Feasibility of Cold Fusion According to the BSM - Supergravitation Unified Theory
    Theoretical Feasibility of Cold Fusion According to the BSM - Supergravitation Unified Theory Stoyan Sarg Sargoytchev York University, Toronto, Canada * E-mail: [email protected] Advances in the field of cold fusion and the recent success of the nickel and hydrogen exothermal reaction, in which the energy release cannot be explained by a chemical process, need a deeper understanding of the nuclear reactions and, more particularly, the possibility for modification of the Coulomb barrier. The current theoretical understanding based on high temperature fusion does not offer an explanation for the cold fusion or LENR. The treatise “Basic Structures of Matter – Supergravitation Unified Theory”, based on an alternative concept of the physical vacuum, provides an explanation from a new point of view by using derived three-dimensional structures of the atomic nuclei. For explanation of the nuclear energy, a hypothesis of a field micro-curvature around the superdense nucleus is suggested. Analysis of some successful cold fusion experiments resulted in practical considerations for modification of the Coulomb barrier. The analysis also predicts the possibility of another cold fusion reaction based on some similarity between the nuclear structures of Ni and Cr. Keywords: cold fusion, LENR, Coulomb barrier, atomic nuclear structures, alpha decay 1. Introduction The scientific research on cold fusion was pioneered by High Flyn (1913-1997), an emeritus professor at the University of Rochester. Being an expert in ultrasonic waves, he advocated a method of cold fusion based on cavitation in liquid metals with injected hydrogen or deuterium and obtained a patent in 1982 [1]. At this time however, little attention was paid since cold fusion was thought to be theoretically impossible.
