I assume the illegible exponent at the bottom of page 1 is 2:
page 1 wrote:P_br = Integral( q_br 4 pi r (exponent of r illegible) dr) over 0 <= r <= R
Should be:

P_br = Integral( q_br 4 π r^2 dr) over 0 <= r <= R

Determination of the minimum possible value of nu_e that can be achieved is of some complexity, for it involves consideration of ion/electron up- and down-scattering collisions in different regions of the system, as well as of the ratio of ion current to electron drive current used to establish and...

Detailed calculations of fusion power density distribution and total fusion power output have been made for a variety of systems, using the EKXL v.4.1 code. Results(ref.6, ref.7) of these show that both the power density distribution and total power are functions of the central virtual anode height...

The major focus for the next generation Polywell is transport. We will be trying to take the machine from "OK" confinement to "good" confinement. Historically, this is a step that has been difficult for fusion machines. The next couple of years are going to be interesting. I also notice that a numb...

There will be a lot to work out once we can prove net power. I know this is offtopic, but in response to what you said, MSimon... Imagine it's the moment Rick Nebel and EMC2 are satisfied that the polywell works. So it's reasonably assured that an investment in the engineering questions will result...

Being the low cost producer is one way. Since polywell is cutting edge, MSimon can achieve lowest cost because he has lots of the engineering background. (This is why high tech has tended to stay in the USA. Not to over generalize or start a flame war or anything.) Having a good brand is another. H...

AC systems handle changing loads much better This is true. But it is more due to transmission line effects. Which to some extent also operate with DC. And yes - DC multi input/output lines would need to be co-ordinated. Yeah. Polywell (or IFR or anything nuclear) is good base load generation. In an...

I don't think telling the world to go back to DC is going to work. AC has a multitude of advantages the first 2 that stand in my mind are: 1. Voltages and currents are easily stepped down and up 2. Very long transmission distances are allowed by high voltage AC Number 2 could be accomplished with h...

So until the machine gets above .35 T the fusion alphas will behave poorly? Smashing into the magrid and causing heat loss? Above .35 T the fusion alphas will circulate and escape at predictable points? What is the Be (Beryllium) fission reaction? http://en.wikipedia.org/wiki/Aneutronic_fusion didn'...

It is surprising, but a large part of your existing household setup is fine on something like 110VDC. The wiring is fine. The fuses and breakers are fine. Anything with a switching power supply is fine (computers, monitors, flat screen TVs, newer stereos and amps, printers, etc.). Even most new wash...

Since I haven't heard anything, I'm deleting http://polywell.nfshost.com. What this means is that anyone can register http://polywell.nfshost.com now. However, there's no meaning to that specific address. You would pick (and register) your real address and then move the site over to your real addres...

Just a note to clarify (thanks, mrchito): http://polywell.nfshost.com is not the final address. However, to start putting content into a site, you create one that's at .nfshost.com first, then you assign it to a domain name, such as http://www.polywellnuclearfusion.com/ . At that point, the .nfshost...

A lot of the convenient features I am talking about would just be things like pre-installed WordPress and other tools that we can use for mashups on the site. Also nearlyfreespeech offers mysql. So if we get that we can just install any of the numerous GPL tools out there. Not as easy as pre-instal...

I was looking for more information about "getting slashdotted"... there is this: A "major slashdotting" of a site hosted on our service will cost you (on average) less than $10, one time. The best part about that is that as soon as it's over, your costs go back to normal, but you'll save any usage-b...
