I get a server stall on this link (from the page you linked):

The other one led to a PDF that I will read later. I'm up to my ears in number crunching at the moment.

Are you trying to do a WB7 size unit with SCs? Your sketch may be proper for that, but given the 29 cm^2 of "engineering" area of SC conductor that MSimon stated was necessary for the WB100, and the ~8in total cross section Tombo claims MSimon stated, the sketch HE made was to scale and the one you...

This is to scale:

As you can see, it is anything but simple.

MSimon wrote:BTW there will be no nubs in WB-100. Because they will melt.

Might as well get rid of them now.

I decided that a long time ago. They were an obvious problem for more than one reason.

The current set up has four stalks. And yet the focus is on nubs. My take: stalks are not a problem because electrons don't circulate. They oscillate. All you need to do (there may be some other things like a high resistance conductive coating on the stalks to make the gradient on the stalks match ...

Yet you seem to want to insert a forest of connections between the round coils (which DrB didn't want) and the shell. Whereas my proposal has, to quote ... oh, YOU, "No unshielded metal. None. Zero. Nada. Zilch." That is what I think DrB wanted. Just two supports per magnet, provided the shell of t...

Personally, I think that the Navy is simply trying to keep DOE out of their business. I don't blame them, either.

No, I claim that the magnetic forces will strive to push all the current carrying members (wires, tubes, whatever) radially outward as if under pressure. True! So far, so good. I further stated that if said wires were placed into trays, said trays could be attached to a strength member within the m...

If you are using Blender to do scaled...er...modeling or drawings, I found a very useful add-on for Blender at the other end of this link: http://www.geneome.net/2007/06/18/bmae-12/ Be advised that Blender has a "plug-in" folder and a "scripts" folder. This thing goes in the scripts folder. If you i...

I can help with the pert charts ad nauseum. I don't like scheduling, but I have done a lot of it.

I do not doubt that the Navy wants this thing to power its new ships. In fact, the Navy would likely be thrilled beyond words if it could be retrofitted into some of their existing hulls, the Virginia Class subs leap to mind immediately. Were I an admiral at BuShips, I would want it for my next clas...

I think this thing is gonna want to spin up and rather quickly. If you can apply a steady torque to a plasma with time-invariant magnetic fields, then you've got a nifty perpetual motion machine. Art, I know you think that this beast hasn't a prayer of ever working. I am even willing to say that ht...

I fail to see the "exoticness" of this design. Layup of this with cryo copper is SIMPLE. All the standard requirements needed to lay this up as a 2-D circular solinoid apply with the 3-D sphere, but it is not hard. Tedius perhaps, but no new technology. Given the data provided by AmSC in their data...

Guys, As much as you want these fancy electromagnets, we do NOT have the techniques to build them. I am not even sure that there are materials available to build them. Internal pressure will NOT serve to support them. Only the materials that they are made from can do that job. I am not telling you t...

You missed the theme of this discussion. We were concerned with the electron losses at the "nubs" that hold the magnet coils together, which as everyone agreed were in tension due to the radially outward magnetic forces. Tom Ligon and I suggested removing the "nubs" to really eliminate the electron...
