They put up a maintenance notice on the ffs org site and I'm working on the problem itself.

[DeltaV]

I dunno.

focusfusion.org - down
fpgeneration.com - gone
Paul Koloc's site - gone
emc2fusion.org - gone
talk-polywell.org - no load 2 or 3 out of 10 attempts

I see a disturbing pattern evolving.

[Ivy Matt]

Well, at least the Tri Alpha website remains unaffected.

... that was mean

FF site and forums upgraded and online although new forum regs remain disabled.

No way in hell this is just a coincidence. Absolutely no reason for emc2fusion to be down for so long. You can build a new site offline and then just replace it when the new one is ready.

Better make a complete backup of talk-polywell. Anybody with a know how on this site should consider it

Edit. Hmm. Only admins can do it apparently. http://www.siteground.com/tutorials/php ... backup.htm

How about passing along some copies? The forum is already on the www after all, should be no reason to hesitate

Correct... but perhaps not for the reasons that you may think.

Never attribute to malice what can be ascribed to ignorance, indifference and generic human stupidity.

Do the elites responsible for the power situation take maximum advantage of that stupidity?

Hell yes.

The forum is stored as a database and includes private information such as personal details and login data so distributing a direct copy of it would be a no-go.

In fact the oppositeis true. There has been no reason for the EMC2Fusion site to be "up" for the past 3 years or there abouts. Remember, EMC2Fusion.ORG was and is NOT EMC2 Inc. With no reason to exist there is no reason for a site.

Perhaps the reason for these internet sites going away is because the people being hind them are too busy doing the real work of developing fusion power itself and, hence, do not have time to maintain a website for information or PR purposes alone. Or they may be developing proprietary advantage, in which case they may not want to draw attention to themselves right now.

The LPP report for July 15, 2013 can be downloaded here.

Topics covered include:

LPP at Google Solve for X Fusion Brainstorming conference: Still leading the field

Moving the goal posts closer: quantum “herding” may allow net energy with lower density requirements

Monolithic cathode planned to achieve plasma purity, higher densities

Also, the "Fusion Energy Flow Chart" Sankey diagram used in the Google Solve for X talk can be found here.

Hyperbolic headlines may attract the clicks, but they leave a bitter aftertaste. I prefer this headline:

LPP makes experimental results data public

Although that may be slightly hyperbolic as well. It seems the data are available upon request.

Interesting review. Ignition with P-B11 is desirable, in DPF, and in point 4, seems to be a goal exclusive to DPF. How does that apply to FRC efforts? And , remember that ignition is not a requirement for proposed P-B11 Polywells.

That smaller scales is desirable, might be related to density ^2 relationships to the fusion rate. If you can compress a smaller starting volume to a proportionately greater density, the fusion rate will be higher than a larger starting volume/ particle number situation. I guess that this is consistent with the limited fusion yields of a few MW of power associated with DPF type of machines. The yield might be increased progressively as the machine size is decreased, but only to the limits of 100 % burn up of the fuel and of course vaporizing the machine.

Heavier gasses compress better in the pinch. I guess this may be related to the momentum of the particles and may actually be a benefit for pB11 over D-D. Perhaps it is enough to overcome some of the cross section disadvantages of the pB11 reaction.

I thought that in the DPF the electrons was in thermal equilibrium with the ions. The saving grace in the DPF is the claimed quantum magnetic effects at huge B fields that limits Bremsstruhlung radiation. The direct conversion scheme for the x-rays may help achieve a net positive useful energy balance, but perhaps is unrelated to the ability to drive the system to ignition conditions .

In the Polywell the electrons are cold- but only in a spacial perspective. In the core where the ion density is greatest the electrons are slow/ cold, on the edge the electrons are hot relative to the local ions (but there are fewer ions to interact with). The average temperature of the ions and electrons is the same. It is the density difference between the ions and electrons at any given radius and electron temperature that leads to net lower Bremsstruhlung radiation in relation to the fusion driving ion core density. Hot electrons drive Bremsstruhlung but only if they interact with ions. The electrons are hot on the edge, but the ion interactions are less . It is a consequence of the potential well combined with the spherical geometry. The ions converge towards the center. The higher speed leads to decreased numbers of particles (ions) per unit area per unit of time if convergence is ignored. But with convergence this difference is overwhelmed by the convergence of these ions to a central core. This consideration is probably required for successful pB11 fusion in the Polywell. Apparently this is not so in the DPF.
