Best Hope For Fusion?

Written by Tim Lash, Focus Fusion Society Contributor. So much resources have been devoted to ITER it must be mankind’s best hope for achieving clean sustained fusion energy. Right? Many countries have devoted billions to its construction. Vast teams of researchers have engaged multiple fronts of science and engineering challenges. Road maps with timelines stretching into decades have been drawn. With so much activity this must be the ideal path to fusion, right? Last month the BBC posted a summary report that paints a pretty grim picture for ITER’s prospects. ITER is an international effort to construct the worlds largest tokamak fusion reactor. The plans call for ITER to be built in southern France. Long ago the scientific community deemed […]

A Hybrid for Nuclear

Written by Tim Lash, Focus Fusion Society Contributor. These days the term hybrid normally refers to automobiles. Most car companies now offer models propelled by both battery powered electric motors and fossil fuel engines. Nuclear reactors can also come in hybrid varieties. In this case the hybrid design features both a nuclear fusion and a nuclear fission component. An article recently posted to power-technology.com offered a comparison of this hybrid reactor design in relation to some of the leading fusion research efforts. All nuclear power stations in the world today use fissile materials for fuel. They use heavy atomic isotopes which split into lighter elements under the right conditions. The most common reaction is when a heavy atom absorbs a […]

Liquid Metal Fusion Reactors

Written by Tim Lash, Focus Fusion Society Contributor. One of the most challenging aspects of sustainable fusion power are the high temperatures required. These high temperatures stress any imagined containment device. Researchers from the Netherlands Organisation for Scientific Research (NWO) tested a containment model lined with liquid metal. They believe such an approach could improve dealing with the severe temperature gradients of fusion plasma. Their findings are documented in an article published in the journal Nature. A plasma reactor trying to sustain fusion is a very corrosive environment. Solid reactor walls and any equipment in proximity to the plasma will become degraded over time. Metallic parts become pitted and brittle with prolonged plasma exposure. Refreshing the liquid metal in this […]

Moon Dreams of Aneutronic Fusion

Knowing What We Know Today August 8, 2017 We learned from history that a Roanoke Colony colony disappeared in 1587. The Anglo-Spanish war prevented anyone from sailing back to the colonists until 1590. If industries finally chase after the mineral riches on the moon, they will need a colony there, and sustainable plans will be required. There is a huge opportunity to advance our science and engineering by setting these large goals, but we must also remember the legacy of those who have sacrificed as explorers. Surviving in that environment should remind us of contingency plans for those distances. There should be ways to rescue pioneers or miners. Moon Pioneers need long term energy plans and a vast number of […]

Optimizing Plasma

Written by Tim Lash, Focus Fusion Society Contributor. Lawrenceville Plasma Physics fusion research has aneutronic hydrogen-boron fueled fusion as its energy production goal. Another fusion project that proposes to use hydrogen-boron fuel takes a clever approach to finding a hot plasma regime. Tri Alpha Energy (TAE) is building a colliding beam fusion reactor. A recent article published in the journal Science Reports outlines a high tech approach to optimize the operating characteristics of their device. By its very nature producing energy via fusion is complex. The science can be daunting, and the machines that attempt to achieve fusion incredibly intricate. These machines generally have a multitude of operating parameters that need to be tuned and calibrated. Response to input parameters […]

Fusion Fuel

Written by Tim Lash, Focus Fusion Society Contributor. Often when considering the relative merits of fusion energy reactor designs the focus lands on underlying scientific principles or construction costs. Rightly so since these are the upfront hurdles to reach viability. Less often is the proposed fusion fuel a topic of comparison. A recent article discussing theoretical extra-terrestrial mining operations touched on the availability of Helium-3 on the moon. Helium-3 is an isotope of helium with one less neutron than the far more abundant helium-4 variant. In fact, there’s only one or two atoms of helium-3 on earth for every million atoms of helium 4. This scarcity makes helium-3 harvested from earth a poor choice for powering a fusion reactor. However, […]

Desperate Energy Needs

Written by Tim Lash, Focus Fusion Society Contributor. The world is in desperate need of energy. Growing populations, dwindling natural resources and continuing global strife place enormous strains on delivering enough energy to all earth’s inhabitants. The primary goal of Lawrenceville Plasma Physics research is to deliver abundant, cheap, green fusion energy to the world. A story recently carried by Reuters emphasizes the ever present need for such energy solutions, and the horrific lengths society can go to satisfy those needs. A town called Douma in war torn Syria supports an energy production facility detrimental to both its workers and the environment. In a series of open furnaces, workers feed plastic waste into the flames. The fumes generated by this […]

More Stellarator News

Written by Tim Lash, Focus Fusion Society Contributor. Recently we posted an update on the Wendelstein 7-X fusion reactor at the Max Planck Institute for Plasma Physics (MPIPP) in Greifswald Germany. This week sees more news on the stellarator front. Southwest Jiaotong University announced plans to build a stellarator fusion reactor. This undertaking will be in partnership with Japan’s National Institute for Fusion Science (NIFS). NIFS already operates a similar reactor in Japan called the Large Helical Device. NIFS and Southwest Jiaotong University will design, implement and construct, plasma heating, technical diagnostics and ultimately conduct plasma experiments. They will then introduce the helical device to be called CFQS (Chinese First Quasi-axisymmetric Stellarator). This announcement is on the heels of another […]

A Shift in Energy Needs to Include Fusion(Part One)

Pictures of energy technologies in the present and near future. Written by Mark Nelson. On June 13, 2017, Stanford University futurist Tony Seba gave a presentation at the Colorado Renewable Energy Society(CRES). He predicts a 13-year ramp up of solar power, autonomous electric vehicles, and large energy storage capacities, all with decreasing prices in the market. This convergence of technologies will cause a disruption in our transportation and energy systems. He presents his case in a YouTube video here. He says it will also disrupt our economic systems, just as the internet, the cell phone, and the adoption of business models have changed the speed of communication. Mr. Seba uses historical references, and a leverage of data trends, asking the […]

Stellarator News

Written by Tim Lash, Focus Fusion Society Contributor. Edited by Ignas Galvelis, Supervising Director. At the Max Planck Institute for Plasma Physics (MPIPP) in Greifswald Germany, a team of scientists and engineers continue working to bring the worlds largest stellarator online. A stellarator is a type of toroidal magnetic confinement fusion reactor. The most common form of toroidal fusion reactor is a tokamak. Tokamaks are shaped like ordinary doughnuts. Stellarators retain the basic doughnut shape but twists its way around to make the loop. This design, while far more complex, allows physicists to craft more ideal magnetic confinement fields. The machine under construction in Germany is called the Wendelstein 7-X (W7-X). The W7-X was first powered up at the end […]
