I presume the solid block of coppery color is a kind of "here there be super conductor" place holder, not anything more. That is correct. As soon as I find the way to turn different objects on and off for a particular render job, I will produce a picture without the core and without the e...

Re: Here lies the critical path!

There is a lot of time to work this out. We don't even have anything close to a net power machine yet. Chief, we'll have the magnets done and we'll be waiting on the Brogdingnag. Without the Brobdingnag, we will be little more than a glorified steam generator. Making steam is fine for the recovery ...

Okay, here is my second pass. This one is a lot smoother with the electrical insulation safely trapped between the metal and the SC Core. The empty slots will be for additional support rings. The two ribs you can now see still need more work. I am going to make some minor changes to their shape and ...

The sole source justification has been posted. https://www.neco.navy.mil/synopsis_file/J&A6.302-1_N6893609R0024_J&A%2009R0024.pdf It makes interesting reading if you're in to that sort of thing. The price seems low for a year long contract. The redactions leave us with some interesting hole...

Here lies the critical path!

Assuming we want to use the p-11B reaction, boys and girls, someone needs to be working on a way to adapt this to a BFR, right now, not tomorrow or the next day. http://www.askmar.com/Fusion_files/Preliminary%20Engineering%20Venetian%20Blind.pdf Golly gee! This is a big son-of-a-gun! Oh, and on the ...

Billy, Keep to the circular model until you have finished it. Complications are only for action later, and then only if they are really needed. We may discuss them, but what you are doing is the basic design which should be followed right through. Will do, Keith. At the moment I am trying to poke h...

There is a paper on this from Uni Wisconsin that shows most DD reactions are outside the grid and accounts for fusion with embedded nucleii. I think they came to the conclusion that there *were some* fast-fast reactions, but I can't find the paper to remind myself of their exact conclusions. That's...

I've not seen any sort of formalised material of that nature. I'm not sure there has ever been 'significant' fusion rates, though I suppose amongst the sweet few neutron counts that have been seen a single count would be 'significant'. Let me know what the data actually is at 5kV and we can visit t...

The Room of Requirement: Material Data.

Let there be a place with links leading to required information on various construction materials for the BFR. http://www.timet.com/index_new.htm I am thinking that the labor costs between using 316SS and Titanium to construct the thing I am working on now, so we may as well go with titanium for the...

The evidence and discussions are scattered around the fusor.net forum. Basically, if you plot out the reactivity curve for DD on a linear scale, you'll see it pretty much asymptotes to zero below 10keV, collision energy. If you then plot out actual neutron emissions from a fusor, that same shape of...

Re: The Bussard Fusion Reactor for Dummies.

It is an essential part of the history of the Polywell to realise that Bussard, like so many with fanciful notions of net power from spherical focussing, believed collisions between fast ions at the centre was the usual order of things. There is essentially no evidence that this ever happens. A 'co...

It still baffles me every time I see a comment here on why ITER won't work. Isn't this a Polywell site? Does it make Polywell more likely to work if ITER won't? I don't see Art saying at all that tests on the Polywell shouldn't happen. He's just predicting that it'll all come to naught. Which the t...

You mentioned that you like the octahedron. I also like it because I have a design based on it that is relatively stron...

Billy, I would like to congratulate you on having introduced some engineering realism to the Magrid design. As you say, you have a long way to go: keep up the good work. I have one suggestion, that you may not wish to incorporate at this stage, but which will need to be considered when you get a li...
