I apologize to tombo for not paying close attention (went to bottom of postings and scrolled up to see image, and then neglected to notice it was a quoted reply). The merged-coil image is "off" in a few ways from my mental image, which is OK since that image preceded my posting by who-know-how-long....

Complicated winding schemes reduce fill fraction. True, but not necessarily unmanageably so. For example, the crossover places could be bigger than the general minor-diameter of each torus. Ideally, each loop-and-a-fraction would be multiplied such that a whole number of loops resulted, in each tor...

To MSimon, Thanks! Excellent image! The next notion to dissect involves pretending all those coils are merged . Open up a single existing torus and you see one wire in there wrapped many times, filling the torus. In a merged design, that one wire snakes around all the toruses. If some distortion occ...

To D Tibbets, well, as long as some ions are oscillating back and forth along the X-axis, some on the Y-axis, and some on the Z-axis, inside a cube, we should be able to get some collisions/fusions. I wouldn't especially object to some electrons being included, EXCEPT for the fact that since they ar...

The Noblefuse design appears to be relying on a combination of the well known "pinch effect" in a plasma that carries an electric current (somehow being made to happen in a tank of heavy water!), plus an external squeezing magnet. The positive ions in the plasma are all basically moving the same dir...

Maybe something like this would help: + ------/ | / | -| | + | / | /------ + - Add an angled plate, also positively charged (probably not sticking out quite as far as portrayed). Ions would be repelled from it in a way that should prevent curving toward the corner. On the next part of the cycle, thi...

Hmmmm...Bussard claimed outright in his Google presentation that "the physics is done". I take that to mean the problems are solve-able, and that possibly some things that some people think are problems actually aren't (the nubbin zones, for example).

OK, then, that is why a "high vacuum" is required in any sort of Fusor (including Polywell). You might note that if some remaining gas atom gets energized by a collision, it is thus encouraged to reach the walls of the container, where the vacuum pumps are. I would tend to think that the presence of...

This idea starts with a nice cube holding a vacuum. On the inside of each face of the cube is a flat metal plate, not quite as large as the face it contacts. The plates will be electrostatically charged. And now for a 2D ASCII sketch: + ---- -| | + | | ---- - The ion guns inject positive ions from t...

To chrismb: When it appears you are mistaking almost everything I write about, and, if I am not to assume that you are a complete ignoramus on these topics, then the only conclusion I can reach is that you are doing it deliberately --being silly, that is. Your most recent message, though, contains o...

charliem wrote:why the declared intention of changing the design of the "nubbins"?

No such thing. I did not know what the nubbins were, when I started writing about the corners. So, I'm talking about affecting the magnetic fields at the corners, and the actual nubbins are completely out of that picture.

To chrismb, it is pure silliness to talk about infinitely-intense magnetic or electric fields; there are none such anywhere on Earth, including any existing Fusor. Nor are there going to be, any time soon. So stop trying to confuse the topic with "singularities", please. Next, round wires in a vacuu...

To hanelyp, the diagram is mostly what I had in mind, but the corner coil doesn't need to be that large. To KitemanSA, one reason I've mentioned an octahedron more than once, for the facet coils, is because there are 4 facets at each corner instead of 3. That means a round corner coil is a better sh...

To D Tibbets, yes, the standard/existing wiring of a Fusor grid is not right for planning DC flow through it. A redesign of the grid would be needed. Keep in mind that I did specify that all the wiring involved (in that redesign) would need to be isolated from other electric circuitry. Even though w...

I copied the message to a new topic. Feel free to delete the old one, and two others (including this one!)
