WASHINGTON, D.C. — The U.S. Department of Energy today announced the winners of $32 million in funding for 15 projects as part of the Breakthroughs Enabling THermonuclear-fusion Energy (BETHE) program. These projects will work to develop timely, commercially viable fusion energy, with the goal to increase the number and performance levels of lower-cost fusion concepts.

“Fusion energy technology holds great potential to be a safe, clean, reliable energy source, but research and development of fusion technology is often constrained by prohibitive costs,” said Under Secretary of Energy Mark W. Menezes. “BETHE teams will build on recent progress in fusion research and the growing fusion community to lower costs and further foster viable commercial opportunities for the next generation of fusion technology.”

“These BETHE projects further advance ARPA-E’s commitment to the development of fusion energy as a cost-competitive, viable, energy generation source,” said ARPA-E Director Lane Genatowski. “Commercially viable fusion energy can improve our chances of meeting global energy demand and will further establish U.S. technological lead in this crucial area.”

Swapping out spent uranium rods requires hundreds of technicians—challenging right now.

Circa 2009 could used for a new fusion reactor using only a magnet.

Physicist Stewart E. Barnes and his collaborators at the Universities of Tokyo and Tohoku, Japan, have created a device that can store energy in nanomagnets.

Physicists have attempted a new way of controlling nuclear fusion and it has worked.

Long Haul

There’s a lot that needs to happen before that pilot fusion plant gets built — if scientists had already conquered the challenges of practical nuclear fusion then the report wouldn’t have been necessary.

“This is the first time in a generation when the fusion community has been called upon to self-organize and figure out its highest priorities for getting from fusion science to fusion energy,” Bob Mungaard, CEO of Commonwealth Fusion Systems, said in the release. “How we can get ready, with data, experience, test facilities — the things that are needed to support the science, and eventually an industry.”

[en] In order to continue cold nuclear fusion reaction reliably and easily, gases of deuterium or deuterium compounds are introduced to a plasma reaction vessel and electric energy is applied to convert the gases into plasmas. Further, deuterium ions are attracted to the surface of materials which cause nuclear fusion by an electric field which is negatively self-biased or externally biased. Atomic deuterium collides against the surface of a cathode on the side of palladium to cause nuclear fusion reaction at the surface or the vicinity of the inside of the cathode. Since a metal absorbing a great amount of deuterium is used as the material for the cathode in order to improve the efficiency and the absorption is increased at a low temperature, the cathode is cooled by liquid hydrogen. Further, the deuterium is introduced in the form of blowing so as to increase the absorption of the deuterium. When the scale is increased by 10 to 1000 times, practical fusion reaction can be caused to utilize as a controllable energy source which can provide a remarkable industrial effect. (N.H.)

:ooooo These could make great fusion devices.

Magnetars are the bizarre super-dense remnants of supernova explosions and the strongest magnets known in the universe.

Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars.

In principle, such magnets can greatly simplify the design and production of twisty fusion facilities called stellarators, according to scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany. PPPL founder Lyman Spitzer Jr. invented the stellarator in the early 1950s.

Most stellarators use a set of complex twisted coils that spiral like stripes on a candy cane to produce magnetic fields that shape and control the plasma that fuels fusion reactions. Refrigerator-like permanent magnets could produce the hard part of these essential fields, the researchers say, allowing simple, non-twisted coils to produce the remaining part in place of the complex coils.

There’s a new breakthrough that might just be the secret ingredient to commercialize “the holy grail of energy,” nuclear fusion.
