What about low cost hot fusion?

On Sept. 17, 2007, Camilo Andrés Urbina Alonso wrote:

I have read some assays from french scientist Jean Pierre Petit that comments on some Sandia Labs Z machine results obtained a few years ago. This scientist claims (and mentions that his colleagues agree) that the Z machine, a very cheap machine compared to the TOKAMAK or the ITER experimental fusion reactors, is enough tool to reach, within a few years and with a fraction of the resources, a commercially viable fusion reactions system.

Petit himself is a very controverted scientist that supports some "out of the box" cosmological ideas, but he is also the only scientist that remained in the field of magnetohydrodynamics in the civil world (as most MHD research is classified). I allways read his assays with help of an online translator, I paste a couple of links on the Low cost fusion he has written. He says that the reason this is not further researched is because it would put fusion at the disposal of every country, something that defense ministries of the G9 will never allow.

More on the Z machine

I have been combing Dr. Petit's assays and I have got much more clear picture.

He recommends for starters to read the French wikipedia article of Z machine (English does not mention the same facts with the same emphasis), I translated it use Google languaje tools.

Under the title: New Perspectives:

In recent experiments (2004-2005) whose results were made public by Sandia in March 2006, the increase in the diameter of the wire network and the replacement of tungsten wire by steel wire made it possible to measure in produced plasmas of the ionic temperatures from 2 to 3 billion degrees. No device of human design had made it possible until now to reach, in a proven way, such temperatures, much higher than those of the heart of stars of average size (about 10exp7 to 10exp8 degrees). They are very largely higher than the temperatures necessary for the fusion of the atoms of hydrogen, deuterium or tritium, and would allow, in theory if not in practice, the fusion of hydrogen atoms with heavier atoms like lithium or boron these two reactions have the advantage of being really clean, insofar as they produce neither neutrons nor radioactive waste, which is not the case of the reactions based on deuterium and tritium.

For the first time, the radiated power exceeded (of a factor 3 to 4) the estimate of the kinetic energy developed during the compression of plasma. The origin in this addition of energy remains still dubious, because only of rare attempts at explanation were published [4] [5]. The first in date is that of Malcolm Haines, professor and researcher in plasma physics to the Imperial College of London it proposes the possible appearance, at the time of the final phase of constriction, of a myriad of microinstabilities MHD from which the kinetic energy would be transferred to the ions, thus increasing the temperature of plasma, then with the electrons, which would release it by emitting x-rays.
