By the way, a "buckeyball" is a truncated icosahedron. It does not meet the criterion for making a polywell because it does not have an even number of faces at each vertex. If you continue to truncate the icosahedron, you get to the point where it is "rectified". At that point you could make a poly...

Maybe you misread it. I said was .5 (0.5) meter radius, not 5 meter radius. Would smaller coli's produce net power?

I had a dream last night

Last night I had a dream that I was involved with building a polywell. The magrid was a buckyball made of 32 0.5 meter radius, frustum shaped coils (similar to the ones proposed by charliem), each one independently suspended from the vaccum chamber by 2 cooling pipes. There were no connectors betwee...

Neutron flux? Aren't we talking about pB11?
pBj still has a neutron flux. About 1E6/cm sq S at the vessel walls IIRC. Side reactions.
And that exceeds the tolerance of DI-BSCCO?

My BOE calculations say that to get reasonable fields - .45T continuous - you have to go to LN2. It is cheap for one shot experiments and can be reliquefied for continuous operation. Or just operated total loss for the first few months to see if further capital investment is warranted. So what's th...

This U-tube video shows how the system works with great detail- err some pretty pictures. From the little I could extract with a brief viewing- ions are injected with an ion gun, further accelerated with injection of high energy(?) electrons , apparently confined laterally with a magnetic field, an...

Could this be viable for WB100? I see a couple of possible advantages: 1. it could be cooled with liquid CO2 and water - cutting cooling cost 2. the simpler cooling would reduce the cross section of the coils - reducing lost energy 3. It will probably be relatively inexpensive compared with other s...

There already exists a 200K superconductor http://superconductors.org/200K.htm The 200K material is believed to have a B212/1212C intergrowth structure, where B=11 and C=copper chain. This structure is shown below left and has the chemical formula Sn6Ba4Ca2Cu10Oy. The general formula for this new fa...
