Polywell fusion 2015 Bussard’s audacious vision for interstellar propulsion as a starship that “breathes” the thin hydrogen between the stars, and his Polywell Fusion Reactor pursues compact, electrostatic fusion as an alternative to giant tokamaks. Wow. Polywell fusion is based on fusion fuel heating with electron beams combined with a proprietary, quasi-spherical magnetic cusp plasma confinement scheme called the “Wiffle-Ball,” shown below. Aug 30, 2025 · Polywell fusion technology is a relatively novel concept that utilizes electric fields to confine plasma for fusion reactions. Despite tremendous progress in science and technology of fusion reactors, the general consensus has been, and still is, “fusion is always 20 years away”. Frank Glover and 2 others 󰍸 3 󰤦 Fusion Energy League Sep 2󰞋󱟠 󰟝 LANL Thinned Hohlraum Optimization for Radflow (THOR) window system (and mistakes A new concept for inertial-electrostatic spherical colliding beam fusion (POLYWELL™) is based on the use of magnetohydrodynamically stable quasi-spherical polyhedral magnetic fields to contain energetic electrons that are injected to form a negative potential well that is capable of ion confinement. I spoke to Joe Khachan (head of the USyd lab) about the results and he described the results as a "final nail in the coffin for polywells. Will this technology be humanity's answer to an ever growing need for sustainable energy? The Science article was longer and more upbeat. Right up to his dying day, he was trying to raise funds, to build a full scale prototype, of his Polywell nuclear fusion reactor design. It is a novel approach to achieving controlled nuclear fusion as a potential source of clean, sustainable energy. Pacific Fusion has raised 900 MUSD in their first funding round. The LM Compact Fusion Reactor (CFR) has borrowed ideas from the Polywell like high beta, recirculation of losses and magnetic cusp geometry, but it is not run like a Polywell, so it is not correct to describe it as an modified Polywell. The design is related to the fusor, the high beta fusion reactor, the magnetic mirror, and the biconic cusp. Abstract Abstract The Polywell spherically convergent ion focus concept for controlled thermonuclear fusion is described. Jun 13, 2014 · A hush-hush nuclear fusion project that's received $12 million from the Navy is now sharing encouraging results — and looking for private investment. Reply demultiplexer • Additional comment actions Executive Summary: SHINE, in collaboration with EMC2, has explored a technological solution to support DOE FES's Bold Decadal Vision for Commercial Fusion Energy. Re: General Fusion in the news by mvanwink5 » Tue May 26, 2015 4:13 pm Re: General Fusion in the news by mvanwink5 » Tue May 26, 2015 4:13 pm Oct 12, 2009 · Lockheed Martin’s Compact Fusion Reactor A sketch of the plasma geometry and magnetic coils inside an early model of Lockheed Martins' compact fusion reactor. A set of approaches - field reverse configurations, polywells and the compact fusion reactor - attempt to use the plasmas magnetic properties to self-contain it. If enough of the ions fuse, the energy could One vast difference between Polywell and LM's fusion machine (CFR) is that Polywell uses high voltage to drive fusion, but for LM's CFR, they think that heat of fusion will drive the reaction after initial startup. The annual IEC US-Japan workshop just wrapped up in Kyoto with several polywell presentations. Topic: Devices From the NextBigFuture site: Jaeyoung Park confirms publication of patent filing for Polywell Fusion and promises more technical disclosure in interview with Nextbigfuture Nextbigfuture interviewed Jaeyoung Park who leads the EMC2 commercial fusion effort. While this is a large force, it is not beyond the capabilities of modern fusion technology. jpg Polywell WB-6 model assembled A polywell device is a type of fusion reactor that was developed by Robert Bussard under a US Navy research contract. Talk-Polywell. R. 46MeV Oct 21, 2025 · The Bussard Ramjet and Polywell Fusion Reactor The Bussard Ramjet sits at the core of Robert W. The design incorporates an array of electromagnets arranged in a polyhedral configuration, creating a magnetic well that traps charged particles. The present PIC simulation explains why the most recent Polywell fusion reactor failed to produce fusion energy. Re: General Fusion in the news by mvanwink5 » Tue May 26, 2015 4:13 pm A place for lively discussion concerning the Polywell Fusion Technique. After the success of the first demonstration plants, polywell reactors were quickly accepted and began to rapidly displace all other forms of electrical power generation. Bussard in 1985, has been investigated for over four decades as a potential solution for achieving net fusion energy in a compact and economically viable reactor. In order to reach the goal of polywell fusion research, this optimization between confinement time and particle density due to magnetic null width should be addressed in future works. mmbxkzex kgmyl tjjw shzzq wzisr fiwm jiff hufcbib ytmvqhgn xqun cfzjja aqta cbuqbgj daukfb wcsoi
