Eric Lerner's Focus Fusion Lecture

Has science taken a wrong turn? If so, what corrections are needed? Chronicles of scientific misbehavior. The role of heretic-pioneers and forbidden questions in the sciences. Is peer review working? The perverse "consensus of leading scientists." Good public relations versus good science.

What has happened in the 13 years since the original 2007 lecture?

The research continues.

Lawrenceville Plasma Physics
Experiments and computer simulations to investigate the capability of DPF for fusion power are underway at Lawrenceville Plasma Physics (LPP) under the direction of Eric Lerner, who explained his "Focus Fusion" approach in a 2007 Google Tech Talk.[25] On November 14, 2008, Lerner received funding for continued research, to test the scientific feasibility of Focus Fusion.[26]

On October 15, 2009, the DPF device "Focus Fusion-1" achieved its first pinch.[27] On January 28, 2011, LPP published initial results including experimental shots with considerably higher fusion yields than the historical DPF trend.[28] In March, 2012, the company announced that it had achieved temperatures of 1.8 billion degrees, beating the old record of 1.1 billion that had survived since 1978.[29][30] In 2016 the company announced that it had achieved a fusion yield of .25 joules.[31] In 2017 the company reduced impurities by mass by 3x and ion numbers by 10x. Fusion yield increased by 50%. Fusion yield doubled compared to other plasma focus devices with the same 60 kJ energy input. In addition, Mean ion energy increased to a record of 240 ± 20 keV for any confined fusion plasma. A deuterium-nitrogen mix and corona-discharge pre-ionization reduced the fusion yield standard deviation by 4x to about 15%.[32]

In 2019, the team conducted a series of experiments replacing tungsten electrodes with beryllium electrodes (termed Focus Fusion 2B). After 44 shots, the electrode formed a much thinner 10 nm oxide layer with correspondingly fewer impurities and less electrode erosion than with tungsten electrodes. Fusion yield reached .1 joule. Yield generally increased and impurities decreased with an increasing number of shots.[33]

In December there was an interview with him on See the Pattern channel:

I am finding it slightly ironic that in Lerner's quest for solar nuclear fusion he has built a device that uses electric current input to force pB plasma to fuse with an overall greater electric current output.

Where did our sun's original electrical input come from? And what mechanisms of nuclear fusion, given that the sun is not an idealised pB plasma mix, are operating within it to cause it to generate within our solar system an overall net positive electric current?

It's interesting how the Vela 'pulsar' looks exactly like a Plasma Focus device in X-ray, Ultraviolet & Infra Red.
https://chandra.si.edu/photo/2013/vela/ and if you run a search for 'Vela Pulsar' you get this:
https://www.google.com/search?q=vela+pu ... 7&biw=1920

So it seems to me that each & every galaxy creates it's own power once it gets going, so even if the initial currents that Z-pinched to get the whole galaxy going are now extinct, or in Dark mode, then every galaxy is still an over-unity power generator. Everything we have been taught about the inevitable plunge towards total entropy is seemingly incorrect - the universe appears to evolve into ever increasing complexity, doing more with less energy in an ever more efficient way. Just like life really. Amino Acids became (eventually) RNA/DNA, single celled life, simple multi-cellular life, and so on - so why should the Cosmos not be a similar process?
You will never get a man to understand something his salary depends on him not understanding.
