The Core

20 10 2008

The Polywell reactor has a core. This is the core of WB6 from EMC2:





This is what it looks like opened up:



the core exposed

the core exposed, you can see the coils of the electromagnet


So lets start by modeling the shape of the core. To make it more interesting, we’ll use the truncated dodecahedron. Supposedly the truncated dodecahedron has advantages over the truncated cube:

This is a simple dodecahedron:




To find the midpoint of the dodecahedron’s planes, we can use the Icosahedron:



So now we can generate a torus at each of the vertices of the Icosahedron, orthogonal to the line connecting the vertices to the origin. But first lets take a look at some of the tool and technologies we might use.

The Big Idea

20 10 2008

The truth is, I don’t really understand the physics of the Polywell reactor. Fortunately I’m not alone. An often expressed sentiment on the forums is that you really need to “build it and see”. I couldn’t agree more. 

So I will attempt to build it. 

How do you build a device when you don’t understand the principles of it’s operation?

Trial and error.

Now you won’t get very far with trial and error if you are making a handful of attempts. But you _might_ get somewhere if you are making a large number of attempts. I’m suggesting applying brute force to the problem.

What this means in practice is a fully automated fabrication and testing cycle. Computers and robots will fabricate, assemble and operate all of the candidate reactor designs. This approach would allow for the fabrication and testing of a large number of reactor designs, potentially in parallel.

Essentially I am describing finding the solution using an evolutionary process. Although the candidate reactor designs can come from human designers or from genetic algorithms.

Now, this all sounds pretty expensive no? I’m sure it will be! So how does a broke loner like me make any progress?

Turns out quite a bit can be done in the pre-production that doesn’t cost money, although is does cost time (lots of it).

It all starts on the computer.
