I have read the book once now, I will need to let the information sit in the back of my mind for a couple of months and try reading it again. I read his book recently, too. It was quite interesting and a good read. I seem to recall that Woodward claims that gravitional potential falls off as 1/r^2 ...

Let me see if I've got this straight: We have a boiler and steam plant that everyone here would agree is of unorthodox design. Moreover, at least some folks here assert the design is actually unsafe. ... I don't know what the regs are like in Italy, but in the US any steam plant (or even a household...

Is there some quantifiable figure-of-merit to say if any of these variants is "better" than the WB-6 configuration? Do we even have a criteria for saying that a particular grid configuration is "acceptable" or "unacceptable"?

For what it's worth, here is an avi of the interior fields of a six-grid WB-7 class system which encloses a diamagnetic sphere whose diameter is 80% of the inscribed diameter of the grids: http://i826.photobucket.com/albums/zz184/kevin_w_baugh/th_wb7_wb.jpg The background color again shows the log-m...

As it turns out, I have the image coils implemented and running for the six-grid system, and should have the dodecahedron working by tonight sometime. I will post the files as soon as I can get the bandwidth. I will go back and look at kcdodd's results.

Gentlemen - I think I understand a bit better now: the plasma ball at the center will behave as a diamagnetic surface. Although not spherical, it can be approximately modeled as a sphere using Kelvin's method of images. The monopole approach is easy to implement (I just add a radial component everyw...

DeltaV: Yes, this is MATLAB on a Windows box. I will look at what other video formats are available; "avi" was easiest. I am also looking into whether I can get the "streamslice" and "pcolor" functions in Octave. KitemanSA: I never quite understood the rationale behind Indrek's superconducting spher...

I think I have the B-field for a dodecahedron grid here: http://i826.photobucket.com/albums/zz184/kevin_w_baugh/th_wb10.jpg Again, the background color indicates the field strength in dB Re: Tesla, and the streamlines are for the in-plane components only. Here is the avi that shows the field strengt...

Here is another avi. As before, it shows the in-plane streamlines as the 2D analysis plane rotates around a vertical axis. In this plot, the background color indicates the strength of the out-of-plane component of the B-field in dB re: 1 Tesla. Note that the out-of-plane field strength drops to zero...

ladajo - Actually, I was going to do one more thing with the WB-7 class grid, and then try a dodecahedron. One thing that I did to get the avi working was to go from explicit descriptions of each field in terms of location in absolute space to a description in terms of each loops magnetic moment (un...

So here is an image of the 3D field strength (in dB Re: Tesla) and the in-plane field streamlines for a WB-7 grid system. Note that I am including all 3 field components (x,y,z) in the field strength calculation, but the streamlines do not show out-of-plane components. The 2D analysis plane rotates ...

Thanks to all for the words of encouragment. I was sitting in a meeting at work when I suddenly went "D'oh! The out-of-plane field lines are going the wrong way!". The model as it sits is in MATLAB, which has a nice streamline generation function. My next step is to (carefully) extend this to a 2D a...

First, my apologies for posting a busted simulation. Let's see if this looks better: the big picture The problem with the original version of the model was that I had the current flowing the wrong way in the out-of-plane loops. The in-plane loops established a B-field flowing out of the system, and ...

Sorry - my bad for trying to do trig at 0700. Yes, both components fall off in the far-field approximation. However the sum of the non-radial components of the six fields cancel. Correction: the non-radial components of the four grids that are in-plane cancel. The two out-of-plane fields are still ...

Sorry - my bad for trying to do trig at 0700. Yes, both components fall off in the far-field approximation. However the sum of the non-radial components of the six fields cancel. If the simulation is broken I don't quite see it, but would be glad to share the code to whomever wants to help me scrub ...
