I found another solid tutorial for Blender. This one is written by a high school teacher. I skimmed it and it appears to be well written and, thank the gods, well organized.

Toroids with Wing-Like Internal Structure.
This is my first rough layout of a toroid with internal similar to the structure of an aircraft wing. It is also the result of me learning to use Blender's built-in render engine: http://farm4.static.flickr.com/3248/3363500549_6871c57f62_o.png This shows a 5 degree segment of the LHe Jacket and the ...

I think a list of standard arguments pro- and anti- would be good too. We seem to spend a lot of time rehashing those. I suspect that all the F.A.Q.s will have a bit of pro and con. I think the pro's and con's should go into a separate document. The glossary is important. A basic explanation of how...

Yes, stainless steel is probably a 2nd choice but it has its issues. It is the obvious choice for the cryogenics. Full command of my software hah! It took me 10+ hours just to add those jumpers and get everything to line up correctly. Now it would have been faster if I had been less picky about ali...

When I started to reply to this yesterday, I was about to just tell you to read what I had already posted. But then Tom Boydston "tombo" did that really nice graphic that I used in my reply to him a few posts back. So I will use it again by reference here. Now I am going to plead with you to read t...

I need an approximate model that is simple enough for me to solve. To calculate (estimate) the forces on the bottom coil (Antarctica) I chose to substitute 2 concentric coils (tropic of cancer and tropic of capricorn) for the 4 coils on edge by reconnecting the corners at the equator (in my imagina...

Okay, my first pass at a design for this thing turns out to have more problems than even I had thought about. Ed Kribbs pointed out to me that my shoes-in-the-pipe idea will suffer from significant sag. We can't have that, so I'll start over. And, Kiteman, you are not that far off on your suggestion...

Conversely to your last statement, I am concerned that you are trying to react loads inefficiently. It is bad enough that the gravity loads on the SC core need to be carried past the thermal barriers to ground. But it seems that you want to carry the magnetic ones too. This seems unwise if there is...

Second, the 1+cm walls an all those courses look WAY excessive unless you are trying to restrain boiling (see first comment). Were it just the fluids, Kiteman, I would take chances with s/10 pipe. [Third, I don't see any real thermal radiation shielding, but that may just be because it is hard to d...

I made this partial model to double check the dimensions I calculated for the magnet placement. This, of course, is the Belarus Tractor version of the magrid: http://farm4.static.flickr.com/3654/3350253171_52d1911be9_o.jpg There is a 2cm clearance between the outermost jackets on the solenoids.

Like this? But 3 support pips for every coil. The pipes are in shadow for the alpha radiation but the lean structure may make it more stabile. http://farm4.static.flickr.com/3437/3347988436_5b20f87cfd.jpg?v=0 That's pretty close insofar as the general configuration goes, Torulf. There are some ques...

The Kavli Foundation?
These kinds of organizations frequently creep me out, but maybe this is worth a shot. The guy who founded it is still alive and can, therefore, influence the directions it takes.
