I would be really happy for helping to achieve practical fusion energy, even if that meant getting a life sentence or death sentence… I would feel that my life had a purpose.

It seems that the war rotten egg heads are complaining here already:

What a shame. Many people from US do not want peace, only war and war, and more war! It sickens me. I am glad I was banned (because I complained about the imperialistic intentions from US towards Iran) from that blog a few months ago, although it is also my favorite one.

To tell you the truth, I am not so much interested in knowing a practical method as knowing if it is possible to arrange a pinching configuration, that is, 2 hydrogen atoms bound by a frozen magnetic field that slowly contracts. 2 hydrogen atoms, only, cannot be bound due their opposite charges. But, if you put them to orbit each other very fast, couldn’t they be bound by a magnetic field, like a quantized plasmoid?

For ice shift, this is why I thought in positioning it close to the transantarctic moutains. But it is too far away of the cost so I don’t think climate change will be a problem.

Because it is easier to dig means of melting ice than a mix of several different kinds of rocks that above 1000C. You can dig and install at the same time.

Digging downwards is interesting because there are kilometers of space to make a 3D planned city. A lot of people in little surface with a lot of available volume for people to live. A city of 10 million people could potentially occupy a surface of a 10 thousand people town, with sparse habitation. A rhomboid of 2kmX500mx4km would give everyone mansion sized houses.

A piezoelectric actuator just expands or contracts with an applied electrical current. A piezoelectric transforms pressure into an electric current, so it would be a matter of compensating a difference in voltage.

Yes, this is the problem of realign the electrodes after each shot. The point of using actuators here is making the system remain at a fixed position.

I am referring to the accuracy of the adjustment, not the total adjustment.

I updated the first post. Check that out.

The problem I see it is that the duration of the plasmoid, at most 50 ns, is much smaller the usual variability of the time from firing to pinch, which is at around 200ns. So, it is hard to have a target.

Hi benf,

Actually, I am trying to see that the nature of the plamoid is a little bit different of what is proposed by Eric, and that the results pB11 plasmoid probably won’t correlate with the D+D. For example, I propose that the nature of the plasmoid is of “subtype” plasmak.

Plasmak is a kind of toroid onion in which the outer layer compresses progressively the inner layers. So, most of the fusion happens in the center. He3 is produced by the fusion of deutrerium. So, in my view, the caputred He3 by the plasmoid magnetic field would emit bremsstrahlung too fast and literally sink to the bottom of the onion. Thus, its presence would disrupt the D+D reaction, given that D+He requires higher temperatures to react. Plus, the He3 would cool faster due its bremsstrahlung emission being 4 times bigger than the Deuterium. That would cool the inner layers and bring down fast the toroid core temperature and thus diminishing further the reaction rates.

So, using neutrons as a gauge for the pB11 plasmoid is not a straightforward case, because pB11 would have a very pure core, which is not the case of D+D.

[MTd2]

But only a small part of those ion beams take part in the reaction. At 100KeV, 10^11 ions occupy about ~1 cm^3 at 1atm. Compressed to lead density, isotermicaly, they would occupy around 100cubic micometers. So, those other ions must be extremely cold and outside the plasmoid or in the periphery. It seems then that proportionally, He 3 disrupts the core of the reaction.

[MTd2]

Oops. It seems I ploted the neutron + 14N -> 14C + P. Sorry! The ones with Deuterium are really small in the interval until some MeV. So, yes, Derek is right. Sorry.

I checked some data, and it seems that the cross section for 14N + D -> 14C + n + p peaks at about 1 barn around 300KeV and 700KeV. This is more than 5 times at both intervals, although there is a valey that dips at 5*10^-2 barns around 500KeV. So, I don’t see why nitrogen would not react.
