Really big changes. However there is no clear winner amongst the alternatives to fossil fuels. Wind, solar, nuclear fission, geothermal… each one has disadvantages and limitations. For this issue, I sought to understand why fusion matters. Why should we continue to invest our physicist’s time and our taxes into researching and realising a source of power that will, if all goes well, start feeding into the electrical grid sometime after 2060? Then on July 14 my dear wife gave birth to our daughter ATTENTION new readers! Anna Norma. That’s her picture there. She’s my answer to the question “why fusion?” Sure, we do not know exactly You’ll find many acronyms and terms in this when we’ll solve the fusion puzzle. But for her sake, and magazine that are most likely foreign to you. Fear for the sake of all our children, we have to. not! We've highlighted them and provided easy- to-understand descriptions on our website: What’s your answer? www.euro-fusion.org/glossary Maybe by sharing our reasons why, other people will take notice. This might inspire others to learn about fusion. That could increase the support for fusion. Which will help us realise it all the sooner. Keep up with all things EUROfusion-related That would certainly be a good thing. online: @FusionInCloseUp Karl Tischler @fusion2050 Editor of Fusion in Europe linkedin.com/company/eurofusion/ [email protected] Have a question, comment or suggestion?

    Journal of Physics & Astronomy Review| Vol 8 Iss 2 The Big Bang Never Happened: A Conclusive Argument Rowland D* Independent Researcher, Canadian Association of Physicists, Canada * Corresponding author: Rowland D, Independent Researcher, Canadian Association of Physicists, Canada, E-Mail: [email protected] Received: February 15, 2020; Accepted: March 2, 2020; Published: March 20, 2020 Abstract For over 100 years, the prevailing belief has been that the universe was created by a big bang singularity. This speculative event is an impossibility that has become a firmly entrenched notion only because of a fundamental scientific error that few have questioned, until now. This paper provides both logical proof and corroborating scientific evidence that the universe could not have begun from a singularity, that galaxies are not receding from the Milky Way, and that we are not on a collision course with Andromeda. Edwin Hubble made faulty assumptions and significant miscalculations. Big bang theory presupposes that somehow the universe spontaneously created itself from nothing. This notion defies both physics and logic, the science of thinking and reasoning. Nothing cannot be the cause of something. Aristotle is reputed to have expressed it this way: “The notion that there could be nothing that preceded something offends reason itself.” Keywords: Big Bang, Astronomy, Astrophysics 1. Introduction For over 100 years, the prevailing belief has been that the universe was created by a big bang singularity. Because of both logical and scientific errors, this speculative event could not possibly have happened. The big bang idea has become firmly entrenched because of a fundamental scientific error compounded by faulty assumptions, presumptive reasoning, and miscalculations.

K. Lau, [email protected] Experimental progress by TAE Technologies has led to successful suppression of MHD insta- bilities in field-reversed configuration (FRC) plasmas using C-2U and C-2W devices. Resultant particle and energy confinement times are on the order of several milliseconds, governed by mi- croturbulence driven transport processes. Understanding these mechanisms is essential towards improved confinement and a viable FRC fusion reactor. Experimental measurements of low frequency density fluctuations in C-2 have shown that fluctuations of the FRC core and SOL exhibit distinct qualities. In the SOL, fluctuations are highest in amplitude at ion-scale lengths and exponentially decrease towards electron-scale lengths. In the core, fluctuations are overall lower in amplitude with a dip in the ion-scale lengths and a slight peak in electron-scale lengths. Using the Gyrokinetic Toroidal Code (GTC), local linear simulations of drift-wave instabilities have found qualitatively similar trends. The SOL is linearly unstable for a wide range of length scales and pressure gradients. On the other hand, the core is shown to be robustly stable due to the stabilizing FRC traits of short field-line connection lengths, radially increasing magnetic field strength, and the large finite Larmor radius (FLR) of ions.

  • TAE Milestone Press Release
    Fusion Energy Milestone from TAE Technologies Validates Path to Cost-Competitive Carbon-Free Baseload Energy Company Raises Additional $280M for Reactor-Scale Demonstration Facility “Norman” Platform Outperforms Goals; Generates Stable High-Temperature Plasmas Additional Funds Will Support Final Step Toward Commercialization Foothill Ranch, CA -- April 8, 2021 -- TAE Technologies, the world’s largest private fusion energy company, has announced a landmark fusion technology milestone by producing stable plasma at 50M+ degrees Celsius in a proprietary compact reactor design that can scale to competitive fusion-generated power. This milestone furthers confidence in TAE’s path to commercialization, and has aided the company in raising $280M in additional funding. When combined with prior rounds, TAE has now raised over $880M from some of the world’s most sophisticated investors. The latest financing is the direct result of TAE achieving its most recent scientific milestone on the path to delivering carbon-free baseload energy from the Hydrogen-Boron (aka H-B11 or p-B11) fuel cycle, the most abundant and environmentally friendly fuel source on Earth, capable of sustaining the planet for millennia. This success crucially confirms a key differentiator of TAE’s patented technology: a positive relationship between plasma confinement and reactor temperature, meaning that the company’s compact linear configuration improves plasma confinement as temperatures rise. By generating such stable high temperature plasmas, TAE has now validated that the company’s unique approach can scale to the conditions necessary for an economically viable commercial fusion power plant by the end of the decade. A portion of the capital will be used to initiate development of a demonstration facility called “Copernicus” that will operate well in excess of 100 million degrees Celsius to simulate net energy production from the conventional Deuterium-Tritium (D-T) fuel cycle.

  • Nuclear Fusion As a Solution to Energy Needs Gerencia De Riesgos Y Seguros
    Nuclear Fusion as a Solution to Energy Needs gerencia de riesgos y seguros Nuclear Fusion as a Solution to Energy Needs Society needs new options to sustainably meet the population’s growing demand for energy. With this objective, researchers worldwide have been working for decades to create fusion power, which is a massive, sustainable source of energy that is a veritable scientific and technological challenge. However, industrial production and commercialization of this power source may not be achieved until the second half of this century. “The search for sources of energy goes back to the dawn of the human race,” acknowledges Carlos Hidalgo, head of the Experimental Physics Division at the National Fusion Laboratory at CIEMAT (Center for Energy, Environmental, and Technological Research). The current problem is that people’s needs have multiplied by a factor of 100 throughout history. And advances in this field of research have caused radical changes in our society. In fact, experts estimate that humans’ demand for primary energy will have grown 25% by 2040 and will be close to doubling by the end of the century. These predicted scenarios will require an investment of more than 2 trillion dollars per year in new energy sources according to the World Energy Outlook 2018, published by the International Energy Agency. If this amount is not invested and a viable solution is not found, it could lead to a large-scale energy crisis. Against this backdrop, fusion power stands out as the principal energy source of tomorrow: clean, safe, and, in theory, limitless. Yet, Hidalgo urges caution as “the need for new strategies to generate, convert, and store power represents a colossal challenge,” while the dynamics of energy markets are increasingly impacted by the exponential growth of the population and demand.

Nov. 2, 2005 Primary Grid Power Potential (Source) Focus Fusion poses overwhelming competition to Tokamak Purports to be a far more feasible and profoundly less expensive approach to hot fusion, in contrast to what the international project (ITER) in France is pursuing. Lawrenceville Plasma Physics is currently researching and developing the Plasma Focus Device for hydrogen-boron nuclear fusion. by Sterling D. Allan Open Source Energy News -- Exclusive Interview (Listen to anchor, Charlee Redman introduce this story) WEST ORANGE, NEW JERSEY, USA -- Imagine a non-polluting power plant, the size of a local gas station, that would quietly and safely power 4,000 homes, for a few tenths of a penny per kilowatt-hour, compared to 4-6 cents/kw-h of coal or natural-gas-powered plants. One technician could operate two dozen of these stations remotely. The fuel, widely available, is barely spent in the clean fusion method, and would only need to be changed annually. That is what inventor Eric Lerner envisions with his focus fusion technology in which hydrogen and boron combine into helium, while giving off tremendous amounts of energy in the process. The size and power output would make it ideal for providing localized power, reducing transmission losses and large-grid vulnerabilities.
