The pie shaped conductors are standard technology in high current long distance power cables. Easing the pieces together is not much of a problem, I think. There are companies that specialize in custom cable manufacture. Once the $$$ are available, the skills are available. Just like almost everythi...

Dr Bussard said in the Google video at 20min 40sec “In the 1985 patent we said the polyhedron must have an even number of faces around every vertex with faces of alternating polarity. The cube does not satisfy this requirement. It has three.” (Paraphrased) Why then did he continue to work on cubic c...

That new MgB2 superconductor should be great for this app. I noticed the company that makes the wire supplies it in round section and in, I believe, kilometer-long continous lengths. I wonder how much wire we would need for a 4T, 3 meter diameter coil? It's ampere-turns that partially determine fie...

Going to larger coils defeats the purpose of increasing the B field with a limited current. If larger diameter coils could carry enough current to create the larger B field it would be better to simply apply that to the main coils. Of course complications are to avoided whenever possible. I thought ...

Indrek's double coil simulation makes me wonder what it would look like if the second coil were smaller, say half the diameter, with the same current but with the current in the same direction as the main coil. The smaller diameter coil would make the field intensity on the centerline higher, so the...

Liquid copper coils? The copper could be circulated to limit max temp. hall effect pump? I have considered a low melting NaK eutectic inside a copper tube. My equations showed the tradeoff of thicker copper and water cooling to be better when considering resistive heating. But someone else should ch...

Yes, I would rather have my ideas escape into the wild than to be captured by someone else. I don't have the resources to nail down any of them with patents so I would rather see every one use them. Those (globally) who are really threats would use them in any case. (assuming I have any that are wor...

The way I see it is: The field lines are closed so any electron orbiting a field line will eventually follow it back into the center of the device. (barring collisional diffusion, walls etc.) i.e. If it follows a field line out through a coil it will come back in through an adjacent cusp. If you loo...

If we dare not post anything that could be patentable then we will get nowhere here.
Because, I suspect that a good patent attorney could find things to patent in most threads.
But it is a big conundrum.
What about open source?

Yes and real pinhole leaks. Usually where the welder starts and stops. I have seen a semi automated welding rig go 2 times around a 30' diameter tank without stopping. The crew does this day in and day out. They are good. Virtual leaks are a different issue they usually involve cavities inside or in...

OK here are what the 8" thick coils look like on a 2 meter dodecahedron with the ones on a 2 meter icosahedrons in between. My assumption being that the closer it is to a sphere the better. Smaller coils give higher fields at their centers for the same current. Generally smoother fields make for smo...

I stand corrected.

The new picture is beautiful.
Way Cool!
Go Guys Go!
Now I have a handle on the diameter of the plasma ball.

I am still curious about the sealing technology.
It makes a big difference in cost and complexity.

Yep, stuck from being hammered against the pin.

There is a picture up at http://www.emc2fusion.org/ EMC2 Fusion showing the WB-7 Test Reactor vessel. All polished stainless steel with a nice logo. I'm seeing a large door with what look like O-Ring compressing clamps. That O-Ring looks too big to buy molded in 1 piece but must be glued from cord ...

My experience with large tanks was we had them built in place from sheet stock with rolled stiffeners. Worked fine for 20' & 35' dia mild steel tanks. It is standard technology you can get lots of competitive bids. I can see no reason why the fabricators could not do the same thing with stainless st...
