Well, burning time itself is not that issue for me. But concentration and quantity are. If time was an issue, I would never believe in the feasibility DPF, because the other similar model, the quasar jet, lasts for 20 orders of magnitude more, according to your model.

BTW, congratulations on your published paper! 🙂 I hope to see its pre print on arxiv… 🙂

I convinced myself now that this won’t work because O15 and N13 rely on spontaneous fission, so it would require high concentrations and great quantity of both elements.

Now, I understand jamesr comment.

You mean, from the big one? The big one is just to make the gas. It would run until it has a quantity. Send it to the smaller and efficient ones, and start them.

The purpose is to rely only in the atmosphere and does not require refuel. The possibility of using an airplane to go to orbit, for example.

Making them in another lossy focus fusion and feeding it right away.

O-15 has a half-life of 122s and N-13’s half-life is 9.9 minutes

in a bound atom these decays are normally via electron capture, but in a plasma this decay time will be different (possibly even longer).

So although the temperature required is in the realm of what a DPF can handle the confinement time needed is impossible for anything other than a gravitationally bound system where the confinement time is essentially infinite (ie a star).

here is a missing element on the cycle, right? which decays in 9.5 minutes among others. So, just like in an ethanol car, where a small tank of octanol is kept for turning up the engine keep the short half life product available just before starting the engine the rest will be produced inside the engine as a by product

I am not good with analogies… So, I’d like what was the difference between the misfiring of before and the more recent ones.

So, the October news was partly the machine playing a red herring on the team…

Wasn’t that achieved by the end of September?

BTW, I also thought about the preshock. Having a larger magnetic field would give a larger set of values to try and less interference from Earth’s magnetic field.

Lerner wrote: If you look at the patent we have, you can see that the only reason that a very small initial magnetic field can influence the very powerful ones in the pinch is because the axial field gets greatly amplified during the run-down and pinch. Introducing the field very late will eliminate this amplification, so will make the field’s effect insignificant.

I read the patent, this is why I said that it also might amplify the random axial asymmetries between the filaments. So, I suggested a stronger one, but not too late.

Seriously now, the only two parameters to play with are pressure and the intensity of the axial field. Going down didn’t work and it seems there is not much room to go up. I am not sure about the reasons, given that 35KV, with the 10 banks that are actually working now, would still allow pinch at significantly higher pressures. So, the only thing that remains is playing with is the axial field.

I think the reason it won’t work with the axial field being constant it is that the path of the filaments are not really radially straight, but slightly randomly bended. So, a constant field will not converge perfectly the filaments to the axis, so they will meat at the axis with slightly different angular momentum. Some of them will bounce a little, others will arrive and converge fast. In the end, the density of the plasmoid will be small.

So, my idea is to let the filaments converge as much as possible and then give a large magnetic pulse. The filaments will be closer to the target, so they will miss the each other less, and will have the required angular momentum.

5F?

[MTd2]

Not news on the websites. Getting a trillion neutrons per shot by adjusting the axial field, as it was be hoped to achieve according to the November updated, was not achieved until now, despite of the persistent attempts to do so…

“All donations at the level of family membership or higher will receive, in addition to Fusion Focus, an autographed copy of the book “The Big Bang Never Happened” by Eric Lerner.”

Damn it, I didn’t notice that the donation should be $100 or more.
