Tiny Amounts of Lithium Improve Temperature, Pressure in Hot Fusion Experiments

Thanks to Matt Severens for sending the following

An interesting article has been posted on the Science Daily website regarding the use of lithium in hot fusion experiments. Researchers from the Princeton Plasma Fusion Lab in Princeton, New Jersey have been doing some testing where they inject tiny grains of lithium into a plasma which undergoes turbulence.

The researchers found that under certain conditions this caused the temperature and pressure to increase dramatically. Lithium has been known by fusion scientists to increase temperatures, but this testing has apparently surprised researchers since only small amounts of lithium raised temperatures more than was expected.

From the article:

High heat and pressure are crucial to fusion, a process in which atomic nuclei — or ions — smash together and release energy — making even a brief rise in pressure of great importance for the development of fusion energy.

“These findings might be a step towards creating our ultimate goal of steady-state fusion, which would last not just for milliseconds, but indefinitely,” said Tom Osborne, a physicist at General Atomics and lead author of the paper.

[. . .]

“These results “could represent the birth of a new tool for influencing or perhaps controlling tokamak edge physics,” said Dennis Mansfield, a physicist at PPPL and a coauthor of the paper who helped develop the injection device called a “lithium dropper.””

Of course there is a big difference between the hot fusion, and LENR approaches — but the fact that small amounts of lithium have a significant effect in these fusion experiments may be somehow connected with the way that lithium seems to enhance Andrea Rossi’s E-Cat and allow for the high temperature reactions that have been achieved in the Hot Cat.

    Essentially this:

    7Li3+p -> 8Be4 -> 2 Alpha -> Mossbauer Effect-> Heat + (2 Alpha + 2e)-> 2He

    Combined with what appears to be hot fusion researchers taking cues and clues from cold fusion experiments and acting like the ideas are their own.

      how can they apply the principles of cold fusion to its opposite? aint this hard…explain how that works

      • US_Citizen71

        It was intended as a sarcastic joke … hence the winking smiley face. Others played off of my joke.

        Hot fusion research has essentially been at a dead end for over 50 years trying to solve the same limitations and problems discovered early on in the research. I found it humorous and ironic that a breakthrough was achieved by using materials (Lithium) currently being used in LENR research and attempts.

        A joke explained loses its humor.

          Sorry honestly I find the ecat and focus fusion to be the best options

  • Tom

    It only took 50 plus years for the hot fusion boys to make this amazing discovery. They were too focused on getting and spending trillions of dollars in taxpayer money to do any experimental work. It took the competition from the LENR faction to light a fire under their butts.

    Commercial aerospace uses aluminum-lithium forging for low cost ultra hard alloys. One company has huge leverage in alumina AND lithium-based alloys – Alcoa: http://www.alcoa.com/hard_alloy_extrusions/en/lafayette_expansion.asp

    Well positioned for LENR??

    This looks like A Papp engine type reaction to me. At the edge of the plasma channel, there is a zone where the heat level allows for the formation of lithium, hydrogen, and lithium hydride nanoparticles to form. These particles will explode when exposed to an EMF pulse. This explosive reaction can be very powerful and will tend to compress the plasma channel from the edge inward.

    There must be a cooling cycle where the nanoparticles can reform. This is why there is a chipping or turbulence in the plasma required to allow for the reformation of the plasma into suspended nano-dust.

    I have away through that LENR in a plasma mode might be configured as a hybrid application of a hot fusion reaction and a Rossi type meltdown plasma reaction. This new lithium based reaction is a Papp engine reaction and hot fusion reaction hybrid. It might be that the fusion reaction is providing the Papp reaction the nuclear radiation it needs to thrive and the Papp reaction is providing the plasma compression that the hot fusion reaction needs to be stable.

      I suspect it is more of a skin effect. A homogenous plasma is very hard to squeeze evenly, since any irregularity get distributed through the whole plasma. Adding a bit of lithium gives a slight increase in rigidity to the outer plasma, creating a surface with different characteristics than the majority of the plasma, but acting very similarly to the bulk. Much like trying to squeeze a handful of water is very hard, but adding jello powder or putting it in a ballon makes it easy to handle and squeeze with predictable results. The lithium will act something like a jello balloon.

    Since the DOE knows about this, everyone does, including the skunk works, ITER, and focus fusion. Due to the huge increase in inertial confinement time, density, pressure, temperature, and heat release, this should put focus fusion into the success region without having to do PB11 with attendant radioactive material problems.

    It seems the atomic community is seeking success wherever it can, especially to steal the thunder and continue to prevent funded LENR.

    After all, if the process can be kept complex and radioactive, then it remains a monopoly exploitation tool, otherwise not.

    I just stumbled across a similar article at http://www.eurekalert.org/pub_releases/2015-05/dppl-tgo052015.php . It seems the news has reached here already, very good! It’ll be interesting to see what they attribute the excess energy to.

  • Obvious

    So…. um… they got excess heat?

        Wait. You mean our boys on Castle Bravo didn’t expect to get TWICE the yield??

        Particularly if used as an antipsychotic.

  • US_Citizen71

    Next they will accidentally discover that if they use Li7 and ionized H they get a sustained fusion reaction. 😉

    • Alan DeAngelis

      Yeah, and some nickel on the reactor walls.

      • Omega Z

        And then they will discover that an Alumina tube will suffice without huge magnetic walls for containment.

        • blanco69

          Yes. This does raise a thought about a potential shift in the hot fusion strategy. It’s possible that they are planning to use their considerable resources to gradually morph themselves into direct compeditors to the current LENR protagonists.If that happens, and they are successful, Rossi could be dropped out of the history books like so many other pioneers. I suspect they’d have to drop the word “fusion” from their labels though.

            Good thing AR has friends in the shade.

          • Albert D. Kallal

            Brilliant!

            While I suspect you are being a bit tong and cheek?

            LENR will not drop out or loose to hot fusion. Hot fusion is super expensive, and the domain of big governments and military projects. Such projects are BIG dollars and fusion STILL does spew out HUGE amounts of deadly radiation during operation. So while there is little if any bad by products from the hot fusion reactor, they are VERY DEADLY during their operation. Huge shielding is required and that radiation is as bad as any fission reactor. Such fusion reactors will kill you without shielding. And much of the machinery does become contaminated during operation.

            ONE thing I much agree: The hot fusion will likely learn and glean VERY much from the cold fusion folks. In fact the resulting first successful hot fusion device will VERY LIKELY be based on a LENR effect!!!

            This is a “most” interesting way to “save” hot fusion (by robbing the intellectual ideals from cold fusion). However at the end of the day, LENR will win due to the relative SIMPLE design and simple safety, and low cost.

            I also think the smaller size will result in LENR “heat” type batteries or cartridges for powering your camping lanterns, camping stove, camping heater etc.

            LENR will this race hands down. In fact it ALREADY has won the race! In fact LENR will likely will remain the winning power source for the next 1000 years of main kind.

            LENR is a history making event – and fission, fusion, coal and EVERY FORM of energy will take a back seat to the new kind of energy!

    Very interesting – and encouraging.
